AbstractIn the world of arts and ceramics, glazes are often used to color or finish clay pieces. These glazes primarily consist of a mixture of silica, fluxes and colorants. During the weighing and mixing of glazes there exists a very concerning possibility of inhaling large amounts of free silica, as well as the inhalation of fluxes such as barium and lithium, which are also highly toxic in their own right. Inhalation of large amounts of silica may lead to silicosis, often referred to as “potter’s rot”. In order to avoid potential health hazards during the mixing operation, it is necessary to install adequate ventilation and/or wear an acceptably rated respirator.

The following report is a detailed analysis and evaluation of the current state of Northern Illinois University’s Respiratory Protection Program in regards to the Studio of Art’s (SOA) ceramic laboratory. This report includes documentation of current mixing procedures as well as existing controls in place to reduce respiratory related health hazards. Ultimately, this report will also consist of feasible recommendations with the goal of leading to a more efficient and practical respiratory program.

1. Introduction

Between the dates of November 3rd through November 7th of 2011, Northern Illinois University, including the School of Art (SOA), was subject to a safety inspection conducted by the Illinois Department of Labor (IDOL). As a result of this inspection, the SOA was issued two citations containing a total of eleven items, each of which carry the potential of an accompanying fine.

Two of the eleven items are closely related to issues that are within the scope of the respiratory protection program concerning the ceramics laboratory. The two previously mentioned cited items both include violations for “Hazard Communication” (See Appendix B). The first, is a failure to provide labels and appropriate hazard warnings on containers comprising of hazardous chemicals as required by OSHA standard 29 CFR 1910.1200(f)(5). The second cited item related to the ceramic glaze mixing operation was a failure to maintain copies of the MSDS’s (recently changed to SDS) as stated by OSHA standard 29 CFR 1910.1200(g)(8). Although the SOA did not incur any financially related penalties, compliance with the cited standards was necessary in order to avoid future financial penalties.

The following report will include an analysis of the remedial steps taken to improve the safety of both the students and staff that participate in, or are in the immediate vicinity of, glaze mixing operations. By conducting several on-site inspections as well as interviews with the head staff technician directly in charge of the ceramics laboratory, vital information was able to be gathered concerning the present respiratory practices and procedures in place within the SoA ceramics laboratory.

Currently, only the head staff technician is responsible for mixing glazes, however if students wish, they are permitted to mix their own glazes. The frequency of glaze mixing operations varies significantly depending on need and demand for a specific glaze. According to the lab technician, mixing operations and procedures can occur anywhere from once or twice a semester, to six or more. Due to OSHA regulations only applying towards employees, students are not required by OSHA to be enrolled into NIU’s respiratory protection program. Thus, due to the ambiguity of OSHA regulations regarding students, students are also not required to wear respirators, but are permitted to do so by NIU if they desire.

Northern Illinois University is responsible for ensuring the safety of its staff in regards to respiratory safety throughout all campus activities and areas requiring some sort of protection. NIU understands that engineering controls may not be enough to ensure the protection of its employees, so the respiratory program is in place to provide protection where those controls lack. The goal of this report is to determine how well the respiratory program covers the activities that take place within the SoA Ceramics Studio. This report considers not only the negative factors within the program, but also the positives aspects that provide exceptional protection against potential respiratory hazards.

2. Materials and Methods

The material under review is the current respiratory program put together by NIU to protect their students and staff against all possible exposures across various places on campus, more specifically, the SoA Ceramics Studio. Along with respirators, other controls in place to reduce the respiratory hazards associated with mixing procedures will also be evaluated. Safety Data Sheets (SDS’s), are also required to see if the respirators used can efficiently protect against all chemicals and particulates students and staff may be exposed to. NIU’s most current and complete respiratory program can be located at; http://www.niu.edu/ehs/health-safety/respiratory/index.shtml

In order to determine whether the selected respirators used to protect the students and staff is indeed effective, quantitative fit testing will need to be conducted using identical respirators to the ones currently in use. The instrument used to conduct the quantitative fit testing was provided by the Department of Technology’s Environmental Health and Safety division. The description of the instrument is as follows:

Manufacturer - TSIDescription - PORTACOUNT PRO PLUSModel # - 8038Serial # - 8038114525NIU Tag # - 306557Last Calibrated - January 2012

**However, take note that any results derived from this instrument are not entirely accurate since it requires calibration. Thus, until the instrument is calibrated, results cannot be considered valid and all data gathered serves only for educational purposes.

3. Results and Discussions

3.1 Results:

With the current materials available, quantitative fit testing was limited solely to N95 respirators. The existing procedure for quantitative fit testing consists of first procuring a secondary mask identical to the mask worn by the employee undergoing testing. This secondary mask must then be probed in order to adequately fit the tubing connecting it to the PORTACOUNT. Once the mask has been probed it is no longer acceptable for normal use other than for conducting fit testing. The results of the fit test will then determine if a specific make and model respirator will appropriately fit and protect the employee being tested.

Although an N95 respirator is not the type of respirator primarily worn by the ceramics studio lab technician, it was the only model on hand that was previously probed and suited for conducting fit testing using the PORTACOUNT. Despite the lab technician ultimately failing his fit test for an N95 respirator, this does not necessarily mean that model respirator is unacceptable for the technician. As previously stated, the instrument is past due its recommended calibration date. Also, the ambient particle reading was just over the recommended lower limit. The lab technician was not entirely clean shaven during the time of the fit test. One or all of these factors may have contributed to the ultimate failing result of the fit test.

3.2 Discussion:

3.2.1 Quantitative Fit TestingAs a viable, more practical, and convenient, alternative method of conducting quantitative fit testing, adapters may be purchased that allow fit testing to be performed on the actual respirator that will be in use. These adapters eliminate the need to purchase and probe additional respirators exclusively for testing use. Furthermore, employees submitted to this type of testing, (in this case, the lab technician) can be certain that their specific and unique respirator is providing adequate protection. Utilizing fit testing adapters also greatly reduces the risk of spreading germs through the sharing probed masks. Since the adapter would make the users mask suitable for testing, this would eliminate the need to use a commonly shared probed mask for testing.

A compatible adapter for the respirator currently in use by the lab technician is pictured below. Depending on the distributor, prices for the adapter vary significantly from around $80.00 to upwards of $240.00. The description of the adapter is as follows:

As seen above, the adapter connects to the filter cartridge of the mask, while the tubing connects to the instrument used to conduct testing i.e. PORTACOUNT.Procuring a quantitative fit test adapter may prove to be extremely beneficial when conducting respiratory fit testing.

3.2.2 Dustpak LEVAs a result of the previously mentioned citations (See Appendix B), in order to address the health and safety concerns of students and staff, the NIU ceramics laboratory acquired a Dustpak portable dust collection system with HEPA filtration. The procuring of this device provided a local exhaust ventilation system that controls emissions during the glaze mixing process. The installation and implementation of this device can ultimately significantly reduce both staff and student’s exposure to airborne particulates.

3.2.3 Enrolling Students into Respiratory Protection ProgramAccording to a draft memorandum addressed to the ceramics studio lab technician as well as other relevant individuals (See Appendix A), “The use of respiratory protection will not be required for graduate students, graduate assistants, and undergraduate upper-division (junior and senior) major students as well as the ceramics technician.” However, the draft memorandum also states, “The SOA will enroll a small and limited (manageable) number of students/staff (per Sido a total of 14) that are comprised of graduate students, graduate assistants, and undergraduate upper-division (junior and senior) major students into the respiratory protection program on an annual basis.” Despite the designation for up to 14 students who may enroll into the respiratory protection program, there are currently no

8


students enrolled. The draft memorandum does however specify that “The ceramics technician will also continue to remain enrolled in the respiratory protection program”.

Although not required by OSHA, requiring students who wish to participate in glaze mixing operations to enroll into the NIU respiratory program is another option that has the potential to significantly reduce exposure to airborne particulates.

3.2.4 Use of Pre-mixed GlazesAlthough pre-mixed glazes serve as a much safer alternative, it may not be financially possible or practical to purchase all glazes pre-mixed. However, if the budget allows it, it may be beneficial to purchase a certain amount of glazes that have been pre-mixed. This may reduce the total amount of mixing needed to be performed by either the lab technician or the students, which may ultimately also reduce total exposure.

3.3 Detailed Program Overview

This section describes the respiratory program itself with an overview of what NIU did well when implementing the program, as well as discussing some areas with the potential to thrive by applying minor adjustments. All information in regards to the program come straight from NIU’s Respiratory Protection Program.

3.3.1 RESPONSIBILITIESThe program has been developed and written by the Department of Environmental Health and Safety and the members of the EH&S administer and conduct the proper evaluations to determine how effective the program is. Personnel are fully qualified by appropriate training and experience commensurate with the complexity of the program.

Some components the plan covers:1. Assessment of potentially hazardous environments utilizing industrial hygiene sampling protocol if warranted.2. Employee respiratory safety training program.3. Advise employees or proper selection of respirators.4. Employee respirator fit tests.5. Medical surveillance for participating employees.6. Review and approve selection of respiratory protection prior to purchase.7. Review respiratory procedures.NIU did a great job with this because it gives the proper information on the various levels of decision making required when determining what protection is needed and when.

3.3.2 SELECTIONThe next part of the program sets up probably the most important aspect of any respiratory protection program, respirator selection. Respirators are determined by what hazards an employee can be exposed to.EH&S makes all decisions with these OSHA requirements taken into consideration:1. All respirators issued to participating employees are NIOSH-approved;

9


2. Potential toxic or irritating contaminant, its concentration and condition (e.g. dust, vapor, fume. etc);3. Type of work performed, such as but not limited to: welding, grinding, sanding, blasting, abrading, cutting, drilling, sawing or other mechanical operations that can affect respirator performance and reliability;4. Nature of chemical or material involved (e.g. corrosive, volatile, etc.) to which a worker is exposed that affects respirator performance and reliability.5. Limitations of the user and the equipment (e.g. protection factor, health conditions, adequate selection of respirator models and sizes for proper fit);6. Presence of other control measures (e.g. engineering and administrative controls, housekeeping, work practices);7. Percentage atmospheric oxygen in the area to be entered (e.g., oxygen-deficient, normal or oxygen-enriched atmospheres).

When these decisions were made, the most important aspect is to meet the requirements set by standards and regulations. Selecting the right respirator for a job is extremely important and these considerations must be taken into the decision making process in order to gain the protection that employees seek. NIU does a great job in listing certain things to consider, like what types of conditions are they to be exposed to, the type of work they are intending to do, limitations which what their choice is, and what other control measures are already in place that could alter the decision making process on the amount of protection needed.

3.3.3 TYPESThe next section is to cover the specific types of respirators that are used throughout NIU's campus.The first type is the Negative Pressure Air Purifying Respirators, which also happens to be the one used by the technician in the SoA Ceramics Studio. An air-purifying respirator (APR) is a full or half face mask with filters (N, P or R 95 and 100) that filters contaminated air as it is drawn in through cartridge filters. These filters are designed specifically for use in the presence of certain hazardous substances [e.g., high efficiency particulate air (HEPA) organic vapor, mercury vapor, acid gas, etc.]. It 6 does not supply oxygen, therefore it shall only be used in atmospheres where the oxygen content ranges between 19.5% and 23.5%. APRs shall not be used in atmospheres immediately dangerous to life or health (IDLH).

The second type of respirator is the Powered Air Purifying Respirator. The positive pressure air-purifying respirator (PAPR) consists of a full face mask, filter cartridge and battery pack. Please note that EH&S does not have PAPRs in stock available for use. Please contact EH&S during the design and develop stage of a project to determine if a PAPR is needed. The PAPR is not an air supplied unit and should not be used in:a) Atmospheres with less than 19.5% oxygen;

b) The presence of contaminants that are not filtered by an appropriate cartridge;

c) Atmospheres immediately dangerous to life and health (IDLH).

10


The third type of respirator is the Air Supplied Respirator. The Air Supplied Respirator (ASR) supplies clean air from an independent source (e.g., airline). Please note that EH&S does not have ASRs in stock available for use.

The fourth and final respirator is the Self Contained Breathing Apparatus (SCBA). Self-Contained Breathing Apparatus supplies clean air from a portable independent source such as an air tank carried on ones back, shoulder or belt. It may be used in IDLH atmospheres, particularly where oxygen may be deficient or the atmosphere toxic.

When determining which respirator would be needed for the Ceramics Studio, the only type that that gives the proper protection is the Negative Pressure Air Purifying Respirator. This is the only respirator type that provides the filter that protects against high efficiency particulate air (HEPA), and is specifically designed for this. There is a chart within the program that recognizes all of the respirator types on campus and the proper use of each in regards of what it protects against.

The APR, with any approved filter, is for particulates by NIOSH for contaminants consisting primarily of particles with mass median aerodynamic diameters (MMAD) of at least 2 micrometers, (i.e., dust). The usage recommended by NIU's EH&S Department is for strictly for dust control. This is the respirator used by the technician when making glazes and mixing clay. Although this program is in place to protect NIU's staff, it is also important that the students are protected. While the staff uses the APR, students are either to supply their own respiratory protection or can use a N95 NIOSH-approved disposable filter.

While in the studio, the technician showed what protection there is to provide students without a proper respirator. There were Honeywell General Purpose dust masks and Stanley Protection Particulate Masks. Just from looking at the box of the Honeywell brand, it was not NIOSH approved and not the appropriate protection for the task determined by the chart on what each type of respirator is intended to protect against. The Stanley Protection Particulate Mask was also not NIOSH approved, but even if it, the fact remains that it is not the right protection for mixing glazes.

Staff use the Half Mask Face piece (Reusable Air Purifying Respirator) Survivair 312000 Premier face piece T-Series.

3.3.4 MEDICAL EVALUATIONS/INITIAL MEDICALA medical evaluation is an important element of an effective Respiratory Protection Program. It is necessary to determine whether an employee is medically qualified to use a given respirator. This is intended to prevent injuries, illnesses, and in rare cases, death from the physiological burden imposed by respirator use. At NIU, employees will not be assigned to tasks requiring the use of respirators unless it has been determined that they are physically able to use the respirator.Before any initial examination or questionnaire is given, NIU will supply the PLHCP with the following information so that he/she can make the best recommendation concerning an employee's ability to safely use a respirator:a) Job tasks that required donning a respirator as outline in employee’s job description;

11


b) Type and size of the respirator to be used by the employee;

c) Duration and frequency of respirator use (including use for rescue and escape);

d) Expected physical work effort;

e) Additional protective clothing and equipment to be worn;

f) Temperature and humidity extremes that may be encountered.The SoA Ceramics Studio is susceptible to creating various dust hazards from glazing and mixing the clays. The respirator that is suggested by NIU to use in this situation fully meet the requirements set by them as well as the regulations and standards referenced within the program itself.Once the PLHCP determines whether the employee has the ability to use or not use a respirator safely, he/she sends NIU’s Department of EH&S a written recommendation containing only the following information:g) Whether or not the employee is medically able to use the respirator;

h) Limitations on respirator use related to the employee’s medical condition;

i) Limitations on the workplace conditions in which the respirator will be used;

j) The need, if any, for follow-up medical evaluations; and

k) A statement that the PLHCP has provided the employee with a copy of the PLHCP's written recommendation.NIU will provide additional medical evaluations if:a) An employee reports to his/her supervisor and EH&S medical signs or symptoms that are related to the ability to use a respirator safely;

b) A PLHCP, the employee’s supervisor, or EH&S informs the division director that the employee needs to be reevaluated;

c) Information from the respiratory protection program, including observations made during fit testing and program evaluation, indicates a need for employee re-evaluation; or

d) A change occurs in workplace conditions (e.g., physical work effort, job duties, protective clothing, temperature) that may result in a substantial increase in the physiological burden placed on an employee.

This is important and done very well by NIU because it may be obvious, but to get the best protection from a respirator, it needs to be used correctly. Once the EH&S Department is informed, performing the reevaluation will ensure that the employee avoids any mistakes in the future. The other factor that was acknowledged in the plan is a change to the working environment. When there is any change in an environment, like work effort and job duties

12


mentioned in the program, there can be physical consequences that can impair the employee and create a possibility of injuries. This does not necessarily apply to the studio.

3.3.5 FIT TESTINGRespirators must fit properly to provide protection. If a tight seal is not maintained between the facemask and the employee's face, contaminated air will be drawn into the facemask and be inhaled by the employee. Fit testing seeks to protect the employee against inhaling contaminated ambient air and is one of the core provisions of our respirator program. In general, fit testing may be either qualitative or quantitative. Qualitative fit testing (QLFT) involves the introduction of a gas, vapor, or aerosol test agent into an area around the employee’s breathing zone.

If the user can detect the presence of the test agent through subjective means, such as odor, taste, or irritation, the respirator fit is inadequate. In a quantitative respirator fit test (QNFT), the adequacy of respirator fit is assessed by measuring the amount of leakage into the respirator, either by generating a test aerosol as a test atmosphere, using ambient aerosol as a test agent, or using controlled negative pressure to measure the volumetric leak rate. Appropriate instrumentation is required to quantify respirator fit in a QNFT.NIU ensures an employee is fit tested under the following circumstances:a) New employee or one that has changed jobs into one that requires respirator work;

b) Whenever a different respirator face mask (size, style, model, or make) is used;

c) At least annually;

d) Whenever the employee reports, or the PLHCP, supervisor, or EH&S makes visual observations of changes in the employee's physical condition that could affect respirator fit. Such conditions include but are not limited to, facial scarring, dental changes, cosmetic surgery, or an obvious change in body weight; and

e) When the employee, subsequently after passing a QLFT or QNFT, notifies the employee’s supervisor, EH&S or the PLHCP that the fit of the respirator is unacceptable. That employee will be retested with a different respirator. Employees must have a fit test of a type that follows the protocols and procedures contained in 29 CFR 1910.134 Appendix A.

Ensuring that a respirator fits properly is by far the most important detail when selecting a respirator. Without performing a fit test, employees can be exposing themselves to dangerous substances when in reality; they think they are providing themselves the proper protection. The technician in the Ceramics Studio was fit tested for his APR respirator, but when a quantitative test was conducted on the N95 respirator, it failed the test. Although from the section above about using the correct respirator for the job, the N95 should not be used in the first place because it does not provide to proper protection in the situations within the lab that require the use of a respirator. Employees are all fit tested for their respirators, but when it comes to students, they are at much more of a risk.

Students are responsible for providing their own respirators or using one of the two Dust mask respirators available in the studio to provide the protection they are required to have.

13


When it comes to fit testing, NIU is not responsible for conducting a fit test on students, so they may be exposing themselves to substances that require a degree of respiratory protection. This should be a requirement for the SoA Ceramic Studio since the NIU Respirator Protection Plan only applies to its staff. Since only students of the SoA can access the lab, it should be a department requirement to conduct a fit test to protect its students that will at any point be using the Ceramics Studio.

3.3.6 SEAL PROTECTIONIt is important to keep a tight seal to eliminate any substances that may have the potential to harm an employee. In order to keep a seal, these guidelines should be followed:1. Facial hair that comes between the sealing surface of the facemask and the face or that interferes with valve function; or

2. Any condition that interferes with the face-to-face mask seal or valve function.

3. If an employee wears corrective glasses or goggles or other personal protective equipment, ensure that such equipment is worn in a manner that does not interfere with the seal of the facemask to the face of the user.

4. For all tight-fitting respirators, employees shall perform a user seal check each time they put on the respirator using the procedures in 29 CFR 1910.134 Appendix B-1 (User Seal Check Procedures) or procedures recommended by the respirator manufacturer that can be demonstrated to be as effective as those in Appendix B-1.

Keeping a seal with the respirator is required to ensure full protection. The technician did have a little facial hair when the fit test was conducted. When it comes to the students, it is hard to determine if there is a seal at all since they are not required to have a fit test performed. If fit tests were required, this would have more importance in regards to the students.

3.3.7 CONTINUING EFFECTIVENESSAppropriate surveillance must be maintained of work area conditions and degree of employee exposure or stress. Employees using respirators should leave the work area to attend to any of the following situations:1. To wash their faces and respirator face masks to prevent eye or skin irritation associated with respirator use.

2. If they detect vapor or gas breakthrough, changes in breathing resistance, or leakage of the mask.

3. To replace the respirator or the filter, cartridge, or canister elements.Maintaining the condition of the respirator is essential to provide the most effective protection possible. Any sort of defect can completely ruin a respirator and disable it from doing its job. The plan does a good job identifying situations to which when to leave the work and care to the respirator.

14


3.3.8 MAINTENANCE and CARE PROCEDURESNIU provides all of its employees a clean and sanitary respirator in good working order. However, each employee is responsible for cleaning and maintaining their own respirator.

They should be cleaned after the following intervals: Exclusively for one employee: As often as necessary to be maintained in a sanity

condition and after each use. Used by more than one employee: Before being worn by different individuals and

after each use. For emergency use: After each use. Used for fit testing and training: After each use.

NIU did a good job on making sure that the respirators they distribute to their employees remain clean and working order. If they are too dirty, they will not function properly and may not protect to the degree which it is supposed to. When sharing, it is extremely important to keep them clean because of possible germ transfer and cause illness between the parties that are sharing. The technician is the only one who uses the respirator given to him, so the first interval is the only one that applies. He cleans it with an alcohol wipe after every use.

3.3.9 STORAGERespirators must be stored in a clean plastic zip-lock bag to ensure that the equipment is protected and not subject to environmental conditions that may cause deterioration. Users are responsible to see that respirators are stored to protect them from damage, contamination, dust, sunlight, extreme temperatures, excessive moisture, and damaging chemicals. Respirators are to be packed or stored carefully to prevent deformation of the facemask and exhalation valve.

The program does well in specifying on how it should be stored, as well as the consequences when this is done incorrectly. With the APR used by the technician, there is a specific plastic zip bag that came with the respirator for the storage aspect. When the visit was conducted, the respirator was properly stored in the bag as the program said it should be.

3.3.10 INSPECTIONNIU’s employees are responsible for inspecting their respirators before using them to identify any defects that can cause any sort of decreased protection. The frequency of the inspections is related to the frequency of the use.

All types used in routine situations: Before each use and during cleaning SCBAs maintained for use in emergency situations: Checked for proper function

before and after each use. Inspections should be conducted monthly.Evaluations should include:1. Respiratory function, tightness of connections, and the condition of the various parts including the facemask, head straps, valves, associated covers and gaskets as well as cartridges, canisters or filters.

15


2. Pliability and signs of deterioration.

3. Self-contained breathing apparatus regulator and warning devices as well as the components listed above. The air and oxygen cylinders shall be maintained in a fully charged state and recharged when the pressure falls to 90% of the manufacturer's recommended pressure level. Metal air bottles shall be hydrostatically tested every 5 years.

Repairs:Respirators that fail an inspection or are otherwise found to be defective are to be removed from service. The decision to discard or repair respirators is to be made only by persons appropriately trained to do so. Only NIOSH-approved parts by the respirator manufacturer are to be used in repairs. Repairs must be made according to the manufacturer’s recommendations and specifications for that type of respirator.

Making sure the respirator to be used is in great working order, regular inspections should be conducted. The program does a good job on the determination of when employees are to conduct their inspections. It describes the evaluation process of what to look at as stated above. Having everything listed helps employees determine if they are forgetting anything. When it comes to repairs, having the right parts that are specifically made for any respirator is important. Different components may not fit correctly in other respirators, which may cause problems when providing the right protection for any sort of job. To our knowledge, there were not any repairs conducted on the respirator that the technician uses.

3.3.11 DISPOSALRespirators that fail an inspection or are otherwise not fit for use and cannot be repaired must be discarded. HEPA cartridges contaminated with asbestos must be disposed of as asbestos waste. Respirators themselves, once cleaned, may be discarded as general waste.This pretty much goes unsaid, if the respirator is not fit for operation, it should not be used. The Ceramics Studio does not need to worry about the asbestos disposal since nothing with their operation contains asbestos. If any employees are to get their respirator replaced, they will need to follow the second procedure of cleaning the respirators before disposal.

3.3.12 TRAININGThe most thorough respiratory protection program will not be effective if employees do not wear respirators, or if wearing them, do not do so properly. Employee training is an important part of the respiratory protection program and is essential for correct respirator use.

NIU’s training program, provided by EH&S, is two-fold, covering both the:a) Respiratory hazards to which our employees are potentially exposed during routine and emergency situations, and

b) Proper use of respirators, including donning techniques, limitations on their use, and their maintenance.

16


NIU is responsible for protecting their employees from all respiratory hazards. Training their staff to know when protection is required as well as demonstrating proper use is the key to any protection plan. From what the technician said about the areas that require some sort of respirator protection, he was fully aware of when it is needed. Along with using it correctly, it is essential to maintain respirator cleanliness and functionality. This is something employees are taught, and from the previous sections about maintenance, NIU did a great job to let their staff know how this is supposed to be done. From the plan, in Appendix 3, there is a respirator training attendance form, which leads for us to believe that there is a class to educate employees on all of the training aspects the program covers.Both training parts are provided prior to requiring an employee to use a respirator in the workplace. However, if an employee has received training within 12 months addressing the seven basic elements of respiratory protection (see "Seven Basic Elements" below) and NIU and the employee can demonstrate that he/she has knowledge of those elements, then that employee is not required to repeat such initial training.

All respirator-using employees need to be retrained when the following situations occur:a) Changes in the workplace or the type of respirator render previous training obsolete;

b) Inadequacies in the employee's use and knowledge of the respirator indicate that the employee has not retained the requisite understanding or skill;

c) Any other situation arises in which retraining appears necessary to ensure safe respirator use.

This aspect of the program is important because if an employee needs to don a new respirator type, it could be entirely different in all aspects than the one he/she previously used. Examples like using an entirely different respirator, having different cleaning procedures or having to maintain it in a different way. In regards to the SoA Ceramics Studio, there should not be any change in a respirator use since it measures up to what the technician will be exposed to. One this that NIU acknowledges is the retraining if the individual cannot retain the information to operate in a safe manner while donning a respirator for whatever reason. If any employee forgets how to properly apply a respirator, they are putting themselves in danger, and that is not the goal of NIU’s EH&S Department. Re-educating that employee ensures that they are aware of skills that they clearly lack to use a respirator in the correct manner.

3.3.13 SEVEN BASIC ELEMENTSNIU employees involved in tasks that may require a respirator are trained sufficiently to be able to demonstrate knowledge of these seven elements:1. Why the respirator is necessary and how improper fit, usage, or maintenance can compromise the protective effect of the respirator.2. What the limitations and capabilities of the respirator are.3. How to use the respirator effectively in emergency situations, including situations in which the respirator malfunctions.4. How to inspect, put on, remove, use, and check the seals of the respirator.

17


5. What the procedures are for maintenance and storage of the respirator.6. How to recognize medical signs and symptoms that may limit or prevent the effective use of respirators.7. The general requirements of 29 CFR 1910.134.

NIU does a great job with this section. They want their employees to be safe when conducting work that require a respirator. All seven elements are equally important when it comes to respirator safety, and they want each employee to know them all. Lacking any one of these elements could put employees in danger to unexpected exposure. One thing to highlight is that if any employee cannot demonstrate that they have full knowledge of any of the elements, they will be required to go back and get trained on it again.

3.3.14 PROGRAM EVALUATIONIt is inherent in respirator use that problems with protection, irritation, breathing resistance, comfort, and other respiratory-related factors occasionally arise in most respirator protection programs. Although it is not possible to eliminate all problems associated with respirator use, NIU will attempt to eliminate as many problems as possible to improve respiratory protection and encourage employee acceptance and safe use of respirators. Department of EH&S will thoroughly evaluate and, as necessary, revise the Respiratory Protection Program in order to reduce problems as much as possible.

Program evaluation involves the following:1. Conducting evaluations of the workplace to ensure that the provisions of the current written program are being effectively implemented and that it continues to be effective;2. Conducting medical clearance and annual follow-up evaluation of all employees required to use respirators;3. Consulting employees who use respirators to obtain their views on program effectiveness and to identify any problems. Problems that are identified during this assessment will be addressed.

NIU understands that their plan may have some holes in it, and this section of the plan allows for opinions from employees that are to follow this plan for their take on it. With the first bullet of the evaluation, this allows NIU to determine if what they are preaching is getting through to their employees and to see if they are abiding to the program. The second bullet is important to determine if all employees have any new medical conditions that they are fit enough to use a respirator. The final bullet is to gain the opinion of the employees that are to follow the program and see if it is effective or not. The technician believed that after he reviewed the program, he could not find anything wrong with it, and believes that it does a great job for its purpose.

4. Conclusion

Upon careful examination and close consideration, the Northern Illinois University Respiratory Protection Program was found to be extremely sound and thorough. It consists of all the specified requirements as stated in OSHA standard 29 CFR 1910.134. The program is clear and concise, but without omitting any vital or necessary information. Also, the way in which

18


EH&S representatives responded to the IDOL citations in a swift and efficient manner by procuring the Dustpak demonstrates wise judgment as well as a genuine consideration for the safety of staff and students.

In regards to the ceramics laboratory, adequate respiratory controls are necessary in order to ensure protection against airborne particulate matter. NIU’s implementation of the Dustpak as previously mentioned serves as a prime example of an adequate control measure. During the mixing operation, the Dustpak acts as a vacuum which is capable of collecting a significant amount of the potentially harmful airborne particulates that are produced while mixing glazes. The collected particulates in the air then pass through a HEPA filter, which in theory should separate many of the particulates before releasing the air back into the lab. Utilizing a local exhaust ventilation (LEV) system such as the Dustpak is extremely efficient because unlike a respirator which can only protect one individual, a LEV has the potential to protect many.

Although the program as it stands is certainly satisfactory, NIU may want to consider some additional methods and controls that would further bring program beyond compliance, thus enhancing the level of safety and protection for both staff and students. For example, currently up to 14 students from the SOA are capable of enrolling into the NIU’s respiratory protection program however, at this time none are enrolled. By taking advantage of this designation, students will be better informed and protected during glaze mixing operations.

Also, NIU may want to consider the implementation of a workshop or seminar where all students who will potentially be exposed to glaze mixing operations have an opportunity to learn about the associated hazards as well as NIU’s respiratory protection program and how to enroll if they choose to do so. This workshop may also include optional fit testing for students desiring to wear respirators.

In order to streamline quantitative fit testing procedures, NIU may choose to recommend and assign all staff and students with similar make and model respirators. Ideally, the selected respirators would all be compatible with the same quantitative fit test adapter. This would allow each individual with a respirator to be able to take a quantitative fit test while wearing their own unique mask thus, eliminating the need to share a probed mask.

Re: Meeting Minutes from Ceramics Glaze Discussion

This memorandum serves to summarize the discussion from the meeting held on 23 September 2013 in which we all met to discuss options for dealing with health and safety concerns in teaching students the techniques of glaze mixing.

The meeting commenced with a brief overview of this issue provided by Mr. Jeff Daurer followed by the distribution of the attached document provided by Mr. Scott Mooberry that outlines four options that the Environmental Health & Safety Department (EHS) considered to assist the School of Art (SOA) in dealing with health and safety concerns in teaching students the techniques of glaze mixing. After thoroughly discussing each option the SOA team expressed preference to pursue the industrial hygiene study (option #4) in hopes that option #4 could become the process that the SOA will operate under for this endeavor.

Per our discussion, the SOA team will acquire, either in a temporary or permanent capacity, the Dustpak portable dust collection system (with HEPA filtration) to enable us to evaluate the effectiveness of the machine in the location in which it will be used. Once Mr. Lee Sido informs

21


EHS that the Dustpak has been acquired, EHS will solicit a proposal from an environmental consultant to perform the industrial hygiene study. Once the SOA has earmarked funding for the environmental consultant’s services, EHS will coordinate the study schedule and format with Sido and the consultant. This process is targeted to be completed within a 90 to 120 day timeframe.

The results of the study will determine which options and associated administrative controls will be incorporated into the glaze mixing process. Regardless of the results, the SOA will purchase and install the Dustpak unit which will provide local exhaust ventilation to control fugitive emissions during the glaze mixing process.

Should results of the study reveal airborne dust concentrations in excess of applicable OSHA permissible exposure limits, then the SOA will commit to implementing the various controls outlined in options two and three. Such controls include, but are not limited to:

Most undergraduate students (especially freshman and sophomores) are limited to participating in the process by using a “pre-mix” glaze.

Mr. Jim Kearns may also provide demonstrations of the glaze mixing technique for undergraduate students.

The SOA may offer opportunities for students to participate in field trips and internships, view glaze mixing technique recordings, and engage in applicable interactive computer technologies.

The SOA will enroll a small and limited (manageable) number of students/staff (per Sido a total of 14) that are comprised of graduate students, graduate assistants, and undergraduate upper-division (junior and senior) major students into the respiratory protection program on an annual basis. This list is subject to change based upon current student enrollment status in the ceramics program but the SOA will ensure that there will not be more than 14 students/staff (as defined above) enrolled in the respiratory protection program in any academic year. The ceramics technician will also continue to remain enrolled in the respiratory protection program. Should the SOA feel the need to increase the enrollment, Dean Holly should initiate a request to meet with the Provost’s Office, Facilities Planning and Operations, and EHS to further discuss and evaluate this request. The SOA will be responsible for funding all costs associated with the enrollment of students/staff in the respiratory protection program and may seek to incorporate such costs into the instructional materials fees for those designated students participating in this program.

22


Should results of the study reveal airborne dust concentrations below applicable OSHA permissible exposure limits, the SOA must, at a minimum, implement the following administrative controls:

Most undergraduate students (especially freshman and sophomores) are limited to participating in the process by using a “pre-mix” glaze.

Mr. Jim Kearns may also provide demonstrations of the glaze mixing technique for undergraduate students.

The use of respiratory protection will not be required for graduate students, graduate assistants, and undergraduate upper-division (junior and senior) major students as well as the ceramics technician. Please note that students/staff must be educated about the potential hazards of glaze mixing prior to engaging in this activity and will be provided with the opportunity to use dust masks if they feel more comfortable doing so in this setting. The use of respirators (e.g., N-95, etc.) would necessitate additional administrative controls but this should be provided as an option to those students who are making a specific request to do so due to an existing medical condition.

Regardless of the study results, if the SOA intends to utilize the Dustpak machine they will commit to implementing the following administrative controls as outlined in option four all of which should be in place prior to the completion of the 90-120 day timeframe.

The SOA will hire the Dustpak local distributor to perform routine maintenance and filter changes in accordance with the operations manual. This should be included in the initial purchase agreement and SOA needs to plan for regular maintenance through the distributor going forward.

The SOA will develop and incorporate specific glaze mixing procedures to 1) ensure students/staff understand the potential hazards associated with the glaze mixing process and to 2) ensure the proper use of the Dustpak unit. Such procedures shall be conspicuously posted in the existing glaze mixing area.

The SOA will develop and provide annual hazard communication training for students and staff. Students/staff must sign appropriate documentation indicating they have participated in such training. The SOA has the option of participating in live classroom training sessions or participating in the on-line training course located at https://connect.niunt.niu.edu/p89r6oxrxrs

Students/staff are required to don other types of PPE (e.g. gloves, goggles, aprons) to prevent inadvertent eye contact, skin absorption and ingestion.
