* Via conference call ** Alternates

II. Minutes 1. The meeting was called to order by Tom Euson, Chair, at 8 Am on Tuesday March 23, 2015. Tom explained that the purpose of the meeting was to determine what the Committee wanted to move forward with during the next revision cycle and to form task groups and assign work as needed so the Committee would be ready for the first draft meeting scheduled approximately a year away. 2. Committee members introduced themselves and their affiliation. Tom told the committee that two

members had resigned/retired from the Committee, Steve Gunsel and Randall Nance. Two new committee members, Anton Jensen and Mark Roeber, were welcomed.

3. Minutes of the Second Draft Meeting for the 2016 edition were approved as written.

4. Nancy provided the status of NFPA 33-2016 edition and answered questions about the next revision

cycle for NFPA 33 and NFPA 34. A NITMAM was received on the document and which means that the amending motion will be heard at NFPA’s technical meeting held in Chicago in June 2015. There were 5 motions submitted to accept public comments as written. Four involve the location of the definitions of limited combustible and non-combustible materials in the document and one motion is related to the definition of limited finishing workstation. NFPA members present at NFPA’s the technical meeting will hear discussion on both sides of the issue and will decide if the amending motions will be accepted or rejected. If the motions are rejected then the document remains as written at second draft. If one or more motions pass, then the committee will be re-balloted on those motions that pass to determine if the Committee now wants to accept the changes created by the motion or not. If the ballot passes then the changes will be made as proposed by the submitter. If the ballot fails, then that section of the document that was part of the motion reverts to previous edition text. Regardless of the outcome of the technical meeting, the 2015 edition of NFPA 33 will be released by August 20, 2015. Tom will be representing the committee position at the meeting. He explained that there would be an opportunity for any other committee members who are attending the meeting to also address the membership if they wished to speak on the motion. It was noted that if this amending motion passes and if the committee votes to accept this change, then NFPA 34 and NFPA 33 would no longer have correlated text, something the committee has been working towards achieving. It was also noted that the definition of limited finishing workstation must include a reference to Chapter 14 or it would not be an accurate definition. Tom asked committee members to let him know if they were planning to attend the annual meeting.

NFPA 34 was released in November 2014 as a consent document. There were questions about whether or not the two documents would still be revised in the same cycle and whether or not the public input dates would change since NFPA 33 would only be released for several months prior to the closing date for public input. Nancy explained that unless the Committee decided otherwise, the two documents would still be in the same 3 year revision cycle.

5. Task Group Reports.

a) Sprinkler Systems for Duct and Stack Protection-Tom George provided an update on the task group work and explained that there continues to be questions about how to establish sprinkler requirements in ducts. He explained that it is not always clear what belongs in NFPA 13 and what requirements belong in NFPA 33 and 34. He also noted the confusion users have about sprinkler requirements for powder coating ducts and how explosion protection affects the requirement for sprinklers. A new task group to address this particular issue was formed as a result. The task group will continue working on a draft and will then ask Nancy to contact NFPA 13 staff to ask for volunteers to work with the task group to develop recommendations to be submitted as public input.

b) NEC Updates-Geoff Raifsnider indicated that Article 516 changes had been submitted to the NFPA 70 (NEC) and that NFPA 70 would be open for public comment from 7/7/15-9/25/15. If anyone wishes to review the changes submitted or make comments, they should sign up for email alerts at www.nfpa.org/70 so they are notified when the document is open for comment.

c) Clarification of Terms Continuous Spraying and Spray Booth/Room-Geoff Raifsnider has done some preliminary work on developing definitions for these terms that better clarify what the terms mean. Several additional committee members volunteered to assist with the task. Geoff will submit public input for consideration at the First Draft meeting.

d) Chapter 8 Task Group-John LeBlanc will continue to work on revising Chapter 8 to better clarify

requirements and to better correlate with requirements in NFPA 30. The task group will also look at how these requirements align with those in NFPA 34. John or another task group member will submit public input for consideration at the first draft meeting.

e) Recirculation/Filtration Task Group-Geoff Raifsnider will be leading a task group to look at issues such as what to do with recirculation ducts in a fire alarm situation (how can you prevent recirculation of smoke but still insure fresh air) and heat in recirculation ducts. Additional committee members volunteered to assist Geoff with this task group and a task group member will submit public input by January.

f) Chapter 18 Task Group-John McKnight provided a draft revision of Chapter 18 on the first day of the meeting. The committee reviewed the draft and had comments related to the assignment of duties for the competent person. The task group met again after the meeting and provided a revised draft on the second day of the meeting. The task group may make additional minor changes and will then submit the final recommended changes as public inputs. The task group chair also asked Nancy to contact individuals on NFPA 409 or in the aircraft spraying industry to see if they would like to join the task group to ensure that the requirements are generic enough to apply to that industry.

6. Other Possible Issues to be addressed during Next Revision. The following issues were discussed and

assignments were made or task groups were formed for issues the committee felt needed to be addressed during the next revision cycle.

a. Review of FIs and Ballot Comments-All FIs were reviewed and the committee voted to

withdraw all FIs since the document currently provides clear guidance on all the questions asked in these FIs. Ballot Comments were reviewed and all action to be taken assigned to a task group or to an individual for follow up. One ballot comment related to an error made in Annex C.2.1. The committee expressed a desire to fix this error with a TIA. Bob Feldkamp and Marty Korecky will work with Nancy to submit a TIA in time for it to be published concurrently with the 2015 edition of NFPA 33.

b. Other Recirculation Issues-To be addressed by the Recirculation Task Group c. Reference language to Figures 6.4 (c) and (d) in NFPA 34 Steve Jensen & Mark Roeber to

review and submit public input for revised language to accompany the Figure. d. Review of 9.5 in NFPA 33 and 9.9 in NFPA 34 –no action needed. e. Removal of additional exceptions in document-(Shane Adams to review 33 and Mark Roeber

to review 34) f. Clarification of how 11.3.4 applies to robot sleeves g. Clarification of 6.5.5 application to open containers (Geoff to submit public input) h. Redo of 6.6.2 in NFPA 34 for consistency (Geoff to work with Nancy to revise) i. Protection requirements for No Spray areas in the booth j. Diagrams in 33 Chapter 6-(Geoff to work with Nancy to revise) k. Change MEC C.2.1 to 30 g/m3-A TIA will be developed by Bob and Marty to correct this error

made during 2016 cycle. l. Air exhaust from mixing rooms- Chapter 8 task group to address m. 9.8.2(1) application-Dean Doherty to do a flow chart n. Smoke detection-Recirculation task group to review o. Discussion on listed Electrostatic applicators-Don Scarbrough asked the Committee to look at

this issue but was not present at the meeting. The Committee requests that Don submit public input with substantiation for the first draft meeting if he should wish to proceed with recommending changes.

p. Questions from Jeff Bennett-The Committee reviewed questions submitted by Jeff Bennett to determine if additional clarification was needed in the standard. Tom will bring responses back to Jeff.

q. Discussion about powder fire frequency-Tom asked the Committee if they had the sense that

there had been an increase in powder fire frequency and asked if further work may be needed to look at powder coating. Most felt that this was not the case and that the standard adequately addresses powder coating, especially after the changes made during the 2016 edition revision.

7. New Business.

a) Submitting input on Membrane Enclosures for Airplane Hangars NFPA 409-Nancy indicated that she had received several calls over the past year asking about the use of membrane enclosures in aircraft hangars. The committee felt that public input to NFPA 409 should be done by one of the NFPA 409 committee members or a member of the aircraft industry. (See also task group membrane enclosures (Item 5(e))

b) Data initiative NFPA. Amanda Kimball from the Research Foundation called in to the meeting and provided a PowerPoint presentation about the types of research resources available to technical committees. The Committee explained that they are considering applying for two grants as summarized in item 9 below.

c) Geoff Raifsnider asked the Committee about the possibility of addressing thermal spraying in

NFPA 33. The Committee discussed the issue and decided that they would not to address the issue since thermal spraying has an inherent source of heat and flame which is contrary to all the standard protections provided in NFPA 33 and 34.

d) Ryan Watt, guest from Duroair, addressed the committee and proposed that several changes be

made to the limited finishing workstations chapter. The committee agreed to form a task group to review this section.

e) Jim Sute spoke about sparking issues with bell washers using acetone as a cleaner and the fact

that it is not considered a VOC. Jim offered to look at the issue of gun cleaners in Chapter 10 and submit Public input if necessary.

f) Tom George agreed to submit public input to NFPA 33 4.3 to further clarify the definition of

basements. g) Dean Doherty and Geoff Raifsnider agreed to develop a flow chart or public input to clarify the

layered requirements for fire protection in NFPA 33.

h) John LeBlanc indicated that he had a concern about propane tanks and the spray application of Adhesives. The propane aerosolizes the adhesive and helps dissolve it. Currently the process is not covered by NFPA codes or standards. NFPA 30 does not cover it since it is a gas and not a liquid, NFPA 30B does not cover it since it is not an aerosol as defined, NFPA 54 said it is not covered since it has a liquid component, therefore he was asking about coverage in NFPA 33. The Committee discussed the process and felt that the aerosolization of the adhesive with a gas would be outside the current scope of NFPA 33. John indicated that he was meeting with industry, the 30B committee and Bob Benedetti, NFPA staff to further discuss the issue and would report back to the Committee if further discussion was needed.

i) Nancy indicated that Chapter 6 of NFPA 33 and Chapter 5 of NFPA 34 still had exceptions that

had not been removed during the 2016 revision. Shane Adams volunteered to submit public input revising the wording in 33 and Mark Roeber volunteered to submit public input to revise the wording in NFPA 34 prior to the public input closing date.

8. Formation of Additional Task Groups and Action Items. Additional task groups to deal with the issue

of protection of powder coating booths (sprinklers versus explosion protection) (TG Chair Marty Korecky), to look at whether or not limited finishing workstation requirements can apply to industries other than automotive (TG Chair John Jurasic), to look at electrical and sprinkler requirements in

flash off and drying areas (TG Chair Shane Adams) and to look at the capacity of a flame detector to detect a fire below a grate in a spray booth (TG Chair Tom Euson) have been formed. A list of all previously formed task groups with volunteers and a list of action items are attached to the minutes. Any committee member who is not listed but who wishes to join one of the task groups should contact Nancy.

9. Several research foundation project proposals will be submitted. One on sprinkler requirements in

ducts (how much water and how to space the sprinklers in the ducts) and another on the application of classified areas to combustible liquids heated above their flashpoints. John LeBlanc volunteered to draft the proposals and circulate them to the committee for review before submitting them to the NFPA Research Foundation Code fund for consideration. The grant proposals are due by the end of November.

10. Given the number of new committee members who have joined the committee over the past year, Tom indicated that he would like to show several video/movies of spray booth fires etc. at the next meeting. He asked if members will see what they have available and asked if we can make these available at the first draft meeting. Nancy will make sure to have the appropriate audiovisual equipment available for the meeting. 9 The Fall 2017 revision cycle has not yet been approved or published by Standards Administration.

However Fall 2017 documents will likely open for public input in late Fall 2015 up till approximately the first week of January. The First Draft Meetings will then most likely be held prior to mid-June of 2016. The Committee indicated that they would like to hold the meeting the week of February 22, 2016 in Florida at or on a beach hotel. The committee requested a location such as Fort Myers, Sarasota or Sanibel Florida. Marty Korecky volunteered to do some checking on possible hotels that may be available and within NFPA’s maximum hotel rate. Nancy will work with Marty and NFPA meetings staff to set up a meeting for that week as soon as possible. Nancy will send out a save the date for that week to all committee members.

Committee Statement

CommitteeAction:

Rejected but held

Resolution: This is new material that was not submitted as a public input and therefore was not included in the firstdraft. The committee needs additional time to review the comment to determine their effect on currentrequirements in the standard and to determine the appropriate chapter to place this material in NFPA 33as well as in NFPA 34. Extracted definition as written will need to be revised to indicate that this is astandard and not a code as indicated in 5.1. The Committee is considering referencing NFPA 5000instead of NFPA 220 as they currently reference. The committee prefers to maintain definitions within thedefinitions section of the document rather than to place the definition within the chapters. The committeewould like additional time to consider how to do this so that it is in accordance with the MOS but alsomeets the Committee's desire to maintain the definition within the definition chapter.

Public Input No. 44-NFPA 33-2015 [ New Section after 3.3 ]

Continuous Spray Application Operations

Recommend the committee provide a definition of 'Continuous Spray Application Operation'.


As a submitting party, I have insufficient technical expertise in this area to offer a definition, but feel strongly that one is needed for clarification of section 9.2 of the standard. The term 'automated' is used in chapter 24 of the 2015 IFC document, and the commentary of the 2015 IFC infers that 'automated' can lead to a 'moving fire.' Other uses of the term 'automated' include a self-operating fixed system. Clarification on the intent of the word 'continuous' would be helpful.

The committee needs additional time to review the comment to determine their effect on currentrequirements in the standard and to determine the appropriate chapter to place this material in NFPA 33as well as in NFPA 34. Extracted definition as written will need to be revised to indicate that this is astandard and not a code as indicated in 5.1. The Committee is considering referencing NFPA 5000instead of NFPA 220 as they currently reference. The committee prefers to maintain definitions withinthe definitions section of the document rather than to place the definition within the chapters. Thecommittee would like additional time to consider how to do this so that it is in accordance with the MOSbut also meets the Committee's desire to maintain the definition within the definition chapter.

A material that, in the form in which it is used and under the conditions anticipated, will not ignite, burn,support combustion, or release flammable vapors when subjected to fire or heat. Materials that are reportedas passing ASTM E136, Standard Test Method for Behavior of Materials in a Vertical Tube Furnace at750°C , are considered noncombustible materials.

(see 5.1)


The explanation for the change to relocate the information on noncombustible materials is being provided in the public input (PI 97) dealing with the relocated language.

Chapter 5 Materials

5.1* Noncombustible material. [NFPA 101, 4.6.13]

5.1.1 A material that complies with any of the following shall be considered a noncombustible material.

(1)* The material, in the form in which it is used, and under the conditions anticipated, will not ignite, burn,support combustion or release flammable vapors when subjected to fire or heat.

(2) The material is reported as passing ASTM E136, Standard Test Method for Behavior of Materials in aVertical Tube Furnace at 750 degrees C.

(3) The material is reported as complying with thepass/fail criteria of ASTM E136 when tested inaccordance with the test method and procedure in ASTM E2652, Standard Test Method for Behavor ofMaterials in a Tube Furnace with a Cone-shaped Airflow Stabilizer, at 750 degrees C).

5.2* Limited combustible material. A material shall be considered a limited combustible material whereall the conditions of 5.2.1 and 5.2.2, and the conditions of either 5.2.3 or 5.2.4,are met. [NFPA 101, 4.6.14]

5.2.1 The material shall not comply with the requirements for noncombustible material in accordance with5.1.

5.2.2 The material, in the form in which it is used, shall exhibit a potential heat value not exceeding 3500BTU/lb (8141 kJ/kg) where tested in accordance with NFPA 259.

5.2.3 The material shall have a structural base of a noncombustible material with a surfacing not exceedinga thickness of 1/8 in. (3.2 mm) where the surfacing exhibits a flame spread index not greater than 50 whentested in accordance with ASTM E84, Standard Test Method for Surface Burning Characteristics of BuildingMaterials, or ANSI/UL 723, Standard for Test for Surface Burning Characteristics of Building Materials.

5.2.4 The material shall be composed of materials that, in the form and thickness used, neither exhibit aflame spread index greater than 25 nor evidence of continued progressive combustion when tested inaccordance with ASTM E84, Standard Test Method for Surface Burning Characteristics of BuildingMaterials, or ANSI/UL 723, Standard for Test for Surface Burning Characteristics of Building Materials, andshall be of such composition that all surfaces that would be exposed by cutting through the material on anyplane would neither exhibit a flame spread index greater than 25 nor exhibit evidence of continuedprogressive combustion when tested in accordance with ASTM E84 or ANSI/UL 723.

5.2.5 Where the term limited combustible is used in this standard, it shall also include the termnoncombustible.

A.5.1 The provisions of 5.1 do not require inherently noncombustible materials to be tested in order to beclassified as noncombustible materials. [NFPA 101].

A.5.1.1 (1) Examples of such materials include steel, concrete, masonry and glass. [NFPA 101]

A.5.2 Materials subject to increase in combustibility or flame spread index beyond the limits hereinestablished through the effects of age, moisture, or other atmospheric condition are considered combustible(see NFPA 259, Standard Test Method for Potential Heat of Building Materials, and NFPA 220, Standard onTypes of Building Construction).

(This is intended to be a new section and the proposal is that it precedes the present 5.1 and notreplace it).


This public input provides a way of eliminating the definitions of noncombustible and limited combustible from chapter 3 and placing them where they can be enforced, in the body of the standard. The location chosen by the public input is not critical to the proponent but should be a choice of the technical committee. The language proposed is an extract from NFPA 101 (Life Safety Code) but an extract from NFPA 5000 would provide the same language.


17 of 108 1/18/2016 12:40 PM

This change provides consistency with both the requirements, and the language, for limited combustible materials and noncombustible materials, within the NFPA system, as agreed to by the major NFPA codes (NFPA 1, NFPA 101, NFPA 5000) and multiple other documents.

There is also an issue that the present definitions within NFPA 33 for limited combustible and noncombustible are not in compliance with the manual of style in that they contain references to other documents (NFPA 259, ASTM E136) and provide requirements in a section that is not enforceable.

The technical committee was opposed to this change at the last cycle with an argument that it was proposed at the comment (second draft) stage; it is now being proposed at the first draft stage.

In 2009, UL simplified its Standard UL 900 for evaluating a filter’s combustibility and smoke generating potential when the filter is exposed to direct flame. The UL Class 2 and UL Class 1 designations are now outdated. Filters are now only required to meet requirements that were formerly recognized as UL Class 2. Filter frames and labels will carry one marking to designate that they meet requirements of the standard.

(1) The air heater shall be located downstream of the recirculation particulate filter and vapor concentrationmonitor.

(2) The surface temperature of the air heater shall not exceed 93 C (200 F).


The proposal addresses the requirement for placing an air heater within the recirculation air stream. Location of the air heater downstream of the recirculation filter reduces the chance of particulate accumulation on the heater. A limit of 93 C (200 F) is consistent will surface temperature limitations elsewhere in the standard.

TITLE OF NEW CONTENT

9.1.1 * Automatic fire protection shall not be required for the interior of any noncombustible exhaust ductor exhaust stack leading from a spray application process, which are maintained free of combustibledeposits sufficient to cause a damaging fire.

A.9.1.1 The systems should be designed to either remove potential combustible deposits before theairstream enters the unprotected duct section, or be designed to prevent particulates from dropping outof the airstream before it is discharged. For liquid spray applications, providing recirculation particulatefilters (as defined in this standard) could reduce the particulates in the airstream to acceptable levels. For powder operations, the ductwork and airflow could be designed to provide the air volume and airvelocity necessary to keep the duct interior clean and free of residual material.


If noncombustible spray process exhaust ducts can be maintained free of combustible deposits, there is no need for automatic fire protection in the ducts. This proposed change will give the user an acceptable option to automatic fire protection without increasing the risk.

(5) Sprinklers shall provide a minimum flow of 114 L/min (30 gpm) per head at a minimum of 1 bar (15psi) pressure.

(6) Sprinklers shall be ordinary temperature rated, unless required to be higher due to operatingtemperatures measured in the ducts, in which case the operating temperature shall be at least 28°C(50°F) above the inside temperature of the duct.

(7) * The system demand shall include the discharge from the hydraulically most remote adjacent headsin a common 100 lineal foot area of duct (horizontal and/or vertical) and 250 gpm (945 l/min)for hose streams.

(8) The supply line to the duct sprinklers shall be equipped with an accessible listed control valve.

A.9.4.6(6)

Consideration should be given to areas of duct resulting in the highest sprinkler discharge demand. Thismay actually include multiple paths of duct, provided the total length of duct under consideration does notexceed 100 lineal feet and all subsections of duct are interconnected.

While a developing fire may follow the direction of airflow and vertical rise in the duct, it should not beassumed that a fire will only occur while the system is operating. Operations such as cutting and weldingcan result in ignition of residues inside the duct while equipment is idle.

Also, in large ducts (width or diameter in excess of 12 ft) where an additional line is added to the duct, bothlines should be calculated if located within the selected 100 lineal foot length if duct.

It is not anticipated that the both the ceiling and duct systems will operate simultaneously if installed inaccordance with this standard and NFPA 13, so a total demand including both duct and ceiling sprinklers isnot required by this section.


The proposed language addresses three issues:

1) Original language discussed in the previous cycle included provision for an additional line of sprinklers inside ducts of large dimensions (width or diameter exceeding 12 ft). This was item was accidentally omitted and is therefore being re-introduced this cycle.

2) NFPA 13 and other standards are largely silent on how to determine the hydraulic demand for a closed head sprinkler system protecting ducts. The proposed language provides a minimum requirement for large systems in which protected ducts exceed 100 lineal feet.

3) It is important to have the capability of isolating either the duct sprinkler systems while leaving the ceiling system active. As duct systems are subject to maintenance, cleaning and head replacement, it is in the facilities best interest to provide a means to leave the ceiling sprinkler system in operation during these times.

Revise text of 11.3

Automated Electrostatic Systems. All automated electrostatic equipment systems shall comply with therequirements of 11.3.1 through 11.3.11. Spray equipment shall be listed or approved. Sprayequipment installed after July 1, 1995 shall be listed.

(Restoring text from NFPA 33-95 9.5)

“9.5 Listing and Approval

9.5.1 Spray equipment shall be listed or approved.

9.5.2 Spray equipment installed after July 1, 1995 shall be listed.”

Substantiation

To reconcile requirements with NFPA 33 – 2016 paragraph 6.4.3. which requires listing.

History

For several decades, up through the 1995 edition, NFPA 33 required listing of all electrostatic apparatus.This requirement was modified following the meeting described below to permit interim operation ofunlisted and incendive equipment under conditions requiring increased capacity for suppression.

At a 1997 meeting of the Finishing Processes Committee in Savannah, representatives of the Americanautomobile industry appeared to apprise the committee of an urgent situation. With representatives ofChrysler, Ford, and General Motors in attendance, Mr Cieslik of Ford Motors, as appointed spokesman forthe industry, presented the following points:

(1) Chrysler and Ford were currently under citation by Federal OSHA for violation of 29 CFR 1910.107(h) which required that all electrostatic apparatus be listed. While not yet cited, General Motors was,as well, not in compliance.

(2) The entire US auto industry was at risk of being shut down by the US Department of Labor if notbrought into compliance.

(3) The industry stated support for the requirement for listing, and accepted a commitment to bring alltheir facilities into compliance, but could not do so within the time allowed by the Department ofLabor. The industry felt that a full conversion to listed equipment could be accomplished in goodorder within three years.

(4) To avert a disastrous shutdown, and to allow operation during conversion to all listed equipment, theindustry appealed to the Finishing Processes Committee to make amendments to NFPA 33 thatwould be acceptable to the Department of Labor for application to 29 CFR 1910.107 during theinterim. Those amendments were made, and are still seen in NFPA 33-2016.

Conclusion

The three years stated by the industry as adequate for conversion to all listed equipment has elapsedseveral times over, and now would be the appropriate time to restore the requirement for listing, and torelieve the conflict with NFPA 33-6.4.3.

All automated electrostatic equipment systems shall comply with the requirements of 11.3.1 through11.3.11.

11.3.4 *

All electrically conductive objects in the spray area, except those objects required by the process to be at

high voltage, shall be electrically connected to ground with a resistance of not more than 1 megohm (106

ohms). This requirement shall apply to containers of coating material, wash cans, guards, hose connectors,brackets, and any other electrically conductive objects or devices in the area. This requirement shall alsoapply to any personnel who enter the spray area.

11.3.5

Conductive objects or material being coated shall be electrically connected to ground with a resistance of

not more than 1 megohm (106 ohms). Areas of contact shall be sharp points or knife edges, wherepossible, and those areas of contact shall be protected from overspray, where practical.

11.3.6

Highly resistive objects (i.e., surface conductivity between 108 and 1011 ohms per square) that exhibit asurface voltage below 2500 volts, as measured using a nonloading kilovoltmeter and when subjected tocoronal current not less than that expected in the application process, shall be considered adequatelygrounded.

11.3.7

Objects or material transported by a conveyor shall be maintained in electrical contact with the conveyor orother grounding contacts. Hooks and hangers shall be cleaned regularly to ensure grounding.

11.3.8 *

Electrostatic apparatus shall be equipped with automatic means to de-energize under any one of thefollowing conditions:

(1) Shutdown of ventilating fans or failure of ventilating equipment from any cause

(2) Stopping of the conveyor carrying objects or material through the high-voltage field unless stopping isrequired by the spray process

(3) De-energizing the primary voltage input to the power supply

(4) Occurrence of excessive current leakage at any point on the high-voltage system

11.3.9

Safeguards such as booths, fencing, railings, interlocks, or other means shall be placed about theequipment or incorporated therein so that they, either by their location or character or both, ensure that asafe separation of the process is maintained.

11.3.10

Signs shall be conspicuously posted for the following purposes:

(1) To designate the process zone as dangerous with regard to fire and accident

(2) To identify the grounding requirements for all electrically conductive objects in the spray area,including persons

(3) To restrict access to qualified personnel only

Public Input No. 85-NFPA 33-2016 [ Section No. A.3.3.2.3 ]

A.3.3.2.3 Spray Area.

This definition identifies the areas in which vapors, residue and combustible powders may exist either insuspension or on surfaces as a result of the normal operation of the equipment. The presence of thesematerials requires various protection measures as identified later in this standard, such as the installationof fire suppression systems.

The following areas are typically not considered part of the spray area: (1) fresh air make-up units; (2) airsupply ducts and air supply plenums; (3) recirculation air supply ducts downstream of recirculationparticulate filters; and (4) exhaust ducts from solvent concentrator (pollution abatement) units.

For the purpose of this standard, the authority having jurisdiction can define the limits of the spray areain any specific case. The spray area in the vicinity of spray application operations will necessarily varywith the design and arrangement of the equipment and with the method of operation. Where sprayapplication operations are strictly confined to predetermined spaces that are provided with adequate andreliable ventilation (such as a properly designed and constructed spray booth), the spray area ordinarilywill not extend beyond this space. When spray application operations are not confined to anadequately ventilated space, then the spray area might extend throughout the room or building areawhere the spraying is conducted.

Spray booth recirculation systems contain a recirculation particulate filter, or series of filters, that have aminimum removal efficiency intended to minimize the potential for particulate accumulation in downstreamareas. The reduction of particulates downstream of these filters reduces the hazards that are found inspray areas.


The proposed new language, some of which was removed from the current definition in the referenced PI, is intended to clarify why the standard defines the spray area so it is possible to better understand the delineation between "spray areas and "non spray areas".

The language that was removed from the definition and placed in this Annex material was describing what a "spray area" is not. While helpful, this language is not part of a definition.

A.4.3

Processes involving flammable or combustible liquids should not be located in any basement area for thefollowing reasons:

1. Lack of egress

2. Lack of access by emergency response personnel

3. The possibility for extensive structural damage should an explosion occur because ofaccumulations of vapors

Note that other requirements, such as NFPA 30’s prohibition of Class I liquids in basements, are stillapplicable. The requirements of 4.3 are not intended to override or reduce any stricter code requirements asadopted by the authorities having jurisdiction.

The walls and doors of the booth or spray area can impact the existing egress paths in any building area,particularly a basement level or upper story where egress pathways are limited. Paragraph 5.1.7 referencesthe egress requirements in Chapter 40 of NFPA 101 (Industrial Occupancies). As spray operations presenta higher hazard than is typical in most non-industrial areas, this is a minimal standard approach.

A means of access for emergency response personnel is also required for both search and rescue as wellas manual fire fighting efforts to control and extinguish a fire involving spray equipment. While many spraysystems are relatively benign, the large variety of equipment and types of coating operations in existenceincrease the likelihood of fires in concealed spaces, or flash fires involving a large area within the occupiedfloor. These can be especially difficult to address in below grade are

In some cases, emergency response access can be provided by grade level access to areas that are partlybelow grade (as referenced in the definition for Basement areas).


Without annex material, it is possible that paragraph 4.3 could be interpreted as an exception permitting Class I liquid storage and handling in basement areas (prohibited in NFPA 30). The annex material clarifies this and provides additional background information regarding the requirements (1) and (2).

In addition, this language is identical to that proposed for NFPA 34 A.4.3.

A.9.1

As indicated in Chapter 8, it is not advisable to keep large quantities of flammable or combustible liquids inareas that expose personnel or important property to injury or loss. The primary reason is that fires inflammable liquids are difficult to extinguish by the usual methods, and if large quantities are involved, theycan spread the fire by flowing over large areas. For fires in small amounts of flammable or combustibleliquids, hand extinguishers or large extinguishers on wheels especially designed for such fires are effective.If large quantities of liquids are to be protected, suitable automatic equipment should be provided andspecial attention should be given to proper dikes, curbs, and drains to prevent the flow to other property.

For the extinguishment of fire in spray residues, handheld fire extinguishers suitable for fire in ordinarycombustibles or hose streams are effective.

Regardless of the level of filtration, residues will accumulate in the exhaust ductwork. Because theductwork is part of the spray area, it must be protected in accordance with Chapter 9. This includes theductwork from a water-wash booth.

Because the particulate filters will accumulate paint residue, they must be protected. The solventconcentrator units, by their design, contain high concentrations of solvent, so they also must be protected.Also, the most commonly used solvent concentrators use activated carbon as the adsorption medium. Thismedium is highly combustible, especially with high levels of solvents absorbed. Ketone solvents pose aneven greater risk.

Because suppression media other than water might damage the carbon bed, water-based suppressionsystems (wet pipe sprinklers, preaction sprinklers, dry pipe sprinklers, and open-head sprinkler delugesystems) are recommended for this application.

The recirculated air supply unit must be protected because of the filter media it contains. Also, many largeair supply units have gas-fired heaters to heat outside make-up air.

Air supply ducts from the particulate filter to the air supply unit and from the air supply unit to the spraybooth are not normally protected, since all particulates have been filtered.

The choice of the automatic fire protection system should always be based on good engineering practice.Generally, for most spray areas, automatic sprinklers are considered most appropriate (see A.9.4).However, consideration must be given to how much water is likely to flow and to how much water is to becontained.

Dry chemical extinguishing systems are most appropriate for small spray application operations (e.g.,automotive refinishing, furniture refinishing, and similar processes) that utilize dry filters to captureoverspray. These systems provide economical adequate protection. They are a viable alternative for anyfacility without sufficient water supply to support an automatic sprinkler system.

Carbon dioxide or clean agent extinguishing systems should be used for open area protection only aftercareful consideration. Holding the required concentration of agent for the period of time needed forextinguishment in a spray booth environment can be difficult. In addition, total flooding with carbon dioxidein normally or potentially occupied areas presents serious health concerns. The time delay required prior todischarge can allow a fire time to grow and spread. Carbon dioxide and clean agent systems, however, arean appropriate choice for protecting electrostatic equipment enclosures inside or immediately outside thespray area.

A.9.4

Spray application operations should be located only in buildings that are completely protected by anapproved system of automatic sprinklers. If the operations are located in unsprinklered buildings, sprinklersshould be installed to protect spray application processes where practical. Because of the rapidity andintensity of fires that involve spray operations, the available water should be ample to simultaneouslysupply all sprinklers likely to open in one fire without depleting the available water for use by hose streams.Noncombustible draft curtains can be used to limit the number of sprinklers that will open.

Even when areas adjacent to coating operations are considered under reasonably positive fire control byadequate automatic sprinkler protection, damage is possible if operations are conducted on floors abovethose containing contents that are highly susceptible to water damage. Waterproofing and drainage ofspray room floors can assist in reducing water damage on floors below. Proper drainage of the largevolume of water frequently necessary to extinguish spray finishing room fires often presents considerabledifficulty.

Automatic sprinklers in spray areas, including the interior of spray booths and exhaust ducts, should be wetpipe, preaction, or deluge system so that water can be placed on the fire in the shortest possible time.Automatic sprinklers in spray booths and exhaust ducts should be of the lowest practical temperaturerating. The delay in application of water with ordinary dry pipe sprinklers can permit a fire to spread sorapidly that final extinguishment is difficult without extensive resulting damage.

The location of the sprinklers inside spray booths should be selected with care to avoid headsavoid sprinklers being placed in the direct path of spray and yet afford protection for the entire boothinterior. When sprinklers are in the direct path of spray, even one day's operation can result in deposits onthe sprinklers that insulate the fusible link or choke open head open sprinkler orifices to the extent thatsprinklers cannot operate efficiently.

Automatic sprinklers should also be located so that areas subject to substantial accumulations of oversprayresidue are protected. Generally, sprinklers are located no more than 1220 mm (4 ft) from side walls ofbooths and rooms and from dry overspray collectors (where applicable). Sprinklers in booths or rooms

should be on Extra Hazard occupancy spacing of 9.3 m2 (100 ft2).

All sprinkler systems in spray areas should be controlled by an accessible indicating control valve.

Use of water as the extinguishing agent for solvent and coating material fires might, in some cases, causeproblems with splashing and “floating” of flaming liquids and residues. This possibility should be includedwith the other factors that are normally considered in the selection of an extinguishing agent. In addition,water from sprinkler or deluge systems, after coming into contact with coating materials, residues, orsolvents, might have to be collected and treated as hazardous waste.

A.9.4.1

Subsection 9.4.1 lists four types of automatic sprinkler systems and requires that the one “most appropriatefor the portion of the spray area being protected” be used. Generally, an open-head sprinkler delugesystem provides the highest level of protection, given that all sprinklers in the protected area flowsimultaneously. This type of system is most appropriate for large, downdraft, water-wash spray boothswhen protecting automatic electrostatic spray application zones.

Wet pipe automatic sprinkler systems are appropriate for protecting spray booths that utilizenonelectrostatic application processes or operations using listed electrostatic application processes. Wetpipe systems are also generally used to protect exhaust plenums (eliminator or scrubber sections), exhaustducts, and air recirculation filter houses.

Dry pipe systems have been included because some exhaust duct designs include sections that are subjectto freezing.

Preaction systems have been included because some spray application processes and equipment can bedamaged by unwanted water discharge. This damage can be disruptive and costly. Powder spray boothsand solvent concentrator (air pollution abatement) systems are examples of systems where it is appropriateto use a preaction system.

Determining the water supply requirements for a paint spray application system requires identification ofthe credible fire scenario that results in the greatest water demand. In small booths, this is typically acombination of the sprinklers within the booth and those in the exhaust plenum and stack.

Large or complex paint spray systems can include some of the following features that require carefulevaluation in determining the total system water demand in the event of a fire:

(1) Multiple (primary and secondary) fire protection systems. A common example is a wet pipe systemcombined with a deluge or water mist system. These systems can operate simultaneously, and thispossibility should be evaluated to ensure that the water supply is adequate.

(2) Large booths with multiple protection zones. The fire scenario determining the required water supplyneeds to take into account the likelihood of involving more than one water-based fire protectionsystem. This is especially true where optical flame detection is used to activate deluge systems.Consider the following:

(a) If optical flame detection can “view” a fire in adjacent zone

(b) Proximity of two zones

(c) Airflow between zones transporting hot gases to adjacent zone

(3) Recirculating or interconnected exhaust systems. In simple exhaust systems, a developing fire tendsto follow the airflow from the source to the exhaust point. However, in recirculating or interconnectedsystems, the possibility exists that airflow will also draw the fire into adjacent systems.

(4) Multiple exhaust plenum areas. Supply plenums are usually devoid of paint or coating residue andcannot be expected to be part of a single fire scenario involving a spray booth or area. Exhaustplenums, including water wash/eliminator sections in downdraft booths, can contain a build-up ofcombustible residue and the airflow naturally draws a fire from the booth into the plenum and then onto the exhaust system. As in the multiple spray zone example, it is possible that more than oneexhaust plenum could become involved.

(5) Concealed spaces. In some booths, external or internal enclosures are provided for the purposes ofpaint and solvent supply, mixing, and recirculation. These enclosures are often protected by wet pipesprinkler systems independent of the primary booth protection systems. Their operation might ormight not be likely during a booth fire depending on the fire separation of these systems from thespray area.

Building areas outside of the spray area or paint booth are not included in the demand calculation, as thefire suppression systems and booth/spray area construction are intended to contain a fire until manualfire-fighting efforts can achieve final fire extinguishment.

Figure A.9.4.3(a) and Figure A.9.4.3(b) show two examples of demand calculation worksheets todemonstrate how both simple and complex systems can be evaluated. Note that the accuracy of thedecisions made in determining the water supply demand depends on the expertise of the evaluator.

A.9.4.6

Water supply requirements for most industrial paint spray operations should be adequate to supply allautomatic sprinklers in the spray area. Loss experience has shown that fires starting in the exhaust ductcan spread to the spray booth and that fires starting in the booth can spread to the exhaust duct.

Sprinklers or sprinkler systems protecting stacks or ducts should be of a type not subject to freezing.Automatic systems are preferred, but manual systems are also acceptable. Nonfreeze or dry-type sprinklersystems can be used in ducts subject to freezing. For some industries, such as the automotive industry,manually operated open-head sprinkler systems have proved to be effective protection for ducts andstacks.

For dry chemical fire protection systems, it might be prudent to double the quantity of agent and its flowrate,compared to a similar size fully enclosed spray booth to achieve the desired degree of protection. This isdue to the relatively unenclosed nature of a limited finishing workstation compared to a traditional spraybooth.

This recommendation is based on a white paper provided by the Fire Equipment Manufacturers’Association titled “Recommendations for Protection of Curtained Limited Finishing Workstations.”

A.14.3.7 8 .2

Substantiation:The MEC value to be used when manufacturer’s information is not available is 30 g/m3. This was in the 2011 edition of NFPA 33 but was inadvertently changed to 15 g/m3 at second draft. The enforceable language in Chapter 15 states the MEC requirements correctly. Section 15.8.1.1 states that if the MEC of the powder has not been established then the concentration of powder in the duct shall be maintained at 50 percent of the MEC (below 15 g/m3) which is half of 30 g/m3. The application of 15 g/m3 would mean the user would have to provide twice the ventilation rate as currently required in the standard in 15.8.1.1.

Related section:15.8.1.1*


103 of 108 1/18/2016 12:40 PM

Where nondeposited, air-suspended powder (powder overspray) is conveyed by ductwork to a recovery system, sufficient airflow shall be provided in the ductwork to maintain the powder concentration in the ductwork at not more than 50 percent of the minimum explosive concentration (MEC) of the powder in use. If the MEC of the powder has not been established, then the exhaust duct powder concentration shall be maintained below 15 g/m3 (0.015 oz/ft3).

D.1.2 Contributing Factors.

Thirty-five of the 250 losses exceeded $100,000 combined property damage and business interruption. Itwas determined that failure to follow one or more of the basic provisions of this standard was the reason forthe large losses in all cases. The most frequent deficiencies were the following:

(1) Lack of complete automatic sprinkler protection. Either no protection was provided or protection waslacking or ineffective in part of the spray area. Normally this was due to lack of protection or sprinklerheads sprinklers coated with overspray in exhaust ducts or the plenum.

(2) Inadequate cutoff between spraying operations and the rest of the plant.

(3) Poor maintenance with excessive buildup of overspray. Failure to keep areas outside booths free ofoverspray residue has resulted in fire spread between booths. Overspray residue can accumulate onthe floor between booths (if ventilation is inadequate or if spraying is done outside booths), theunderside of roofs near where the exhaust ducts penetrate (through loose-fitting duct sections), andon the roof around the discharge openings of several booth exhausts. Fire in one booth traveled upthe exhaust, ignited overspray deposits on the roof, and, in turn, ignited deposits in exhaust ducts ofother booths.

(4) Use of finishing materials containing nitrocellulose. In these losses, personnel discovered the fireimmediately and used portable extinguishers during the early stages of the fire but were unable tocontrol the fire. The fire either flashed across overspray residue outside booths, immediately involvinga large area, or burned in a concealed area where it could not be reached. Smoke quickly drovepersonnel out of the area. Automatic sprinklers can protect the room and the structure of the boothand duct system. However, if there is a continuous surface of residue between booths, the sprinklersmight not prevent spread of fire from one booth to another. Good housekeeping and use ofwater-wash booths are basic to spraying operations involving finishing materials containingnitrocellulose.

3.3.X BASEMENT.

Any story of a building wholly or partly below grade plane that is not considered the first story above gradeplane.


Paragraph 4.3 references basement areas within the standard. For the purposes of clarity, a common definition with other NFPA standards should be adopted within NFPA 34. The proposed language is identical to that used in NFPA 101 and 5000.

5.2.2 .1

If the dipping or coating equipment u lizes flammable or Class 1 combus ble liquids and is enclosed for thepurpose of confining vapors and mists, any panels for light fixtures or for observation shall be ofheat-treated glass, laminated glass, wired glass, or hammered-wired glass, and the panels shall be sealedto confine vapors or mists to the enclosure.

Exception: If 5.2.2.2 If secondary enclosures are provided, including those installed for environmentalpurposes designed to capture low-level fugitive emissions, as well as those used for the purpose of anyvision, panels construc on of other materials shall not be required to meet the requirements of 5.2.2 . bepermi ed.

5.2.2. 1 3

Panels for light fixtures shall be separated from the fixture to prevent the surface temperature of the panelfrom exceeding 93°C (200°F).

5.2.2. 2 4

The panel frame and method of attachment shall be designed to not fail under fire exposure before thevision panel fails.


: Current 5.2.2 reads that flammable and combustible operations would have to have wired glass. We believe that is what the exception is trying to depict but this helps to clarify.

Add the following text between Par. 6.3.2 and 6.3.3

6.3.2A Protection Techniques. Section 500.7(A) through (L) shall be acceptable protection techniquesfor electrical and electronic equipment in hazardous (classified) Division locations. Protection techniquesshall not be degraded by the dipping, coating, or printing process .

Add the following text between Par. 6.3.5 and 6.4

6.3.5A Protection Techniques. Section 505-8(A) through (I) shall be acceptable protection techniques forelectrical and electronic equipment in hazardous (classified) Zone locations. Protection techniques shall notbe degraded by the dipping, coating, or printing process.


Although NFPA 70 Article 500 and 505 allow the use of gas detection sensors as a protection technique for hazardous locations, gas detection sensors are not mentioned in NFPA 34 making it unclear as to whether they can be used or not. To clarify I recommend adding a statement to NFPA indicating that any of the protection methods can be used. I also added a statement that the protection method shall not be degraded as a result of the process.

By adding this text to NFPA 34 it will be clear that all the hazardous location protection methods in NFPA 70 Article 500.7 and 505.8 can be used.

A.4.3

Processes involving flammable or combustible liquids should not be located in any basement area for thefollowing reasons:

(1) Lack of egress

(2) Lack of access by emergency response personnel

(3) The possibility for extensive structural damage should an explosion occur because of accumulationsof vapors

Note that other requirements, such as NFPA 30’s prohibition of Class I liquids in basements, are stillapplicable. The requirements of 4.3 are not intended to override or reduce any stricter code requirements asadopted by the authorities having jurisdiction.

The walls and doors of the booth or spray area can impact the existing egress paths in any building area,particularly a basement level or upper story where egress pathways are limited. Paragraph 5.1.7 referencesthe egress requirements in Chapter 40 of NFPA 101 (Industrial Occupancies). As spray operations present ahigher hazard than is typical in most non-industrial areas, this is a minimal standard approach.

A means of access for emergency response personnel is also required for both search and rescue as wellas manual fire fighting efforts to control and extinguish a fire involving spray equipment. While many spraysystems are relatively benign, the large variety of equipment and types of coating operations in existenceincrease the likelihood of fires in concealed spaces, or flash fires involving a large area within the occupiedfloor. These can be especially difficult to address in below grade are

In some cases, emergency response access can be provided by grade level access to areas that are partlybelow grade (as referenced in the definition for Basement areas).


This language is to provide additional clarity as to the intent of paragraph 4.3 and also to parallel the language being proposed for NFPA 33 paragraph 4.3.
