NFPA 13 and 14 should be cons is ten t wi th each other and take in to account Model Bu i ld ing Codes and most municipal codes whose requirements are more r e s t r i c t i v e than e i t h e r NFPA 13 or 14.

A l l CABO Codes fo r bu i ld ings over 75 fee t in height requ i re the f o l l ow ing :

l ) Water suppl ies up to 15,0DO gal lon~ in Seismic Zones two and three

2) A minimum of two r i se rs which must be manifolded together at vary ing bu i ld ing heights

3) Onsite suppl ies requ i re a hose stream discharge of I00 gpm on every f l o o r and every r i s e r .

Sections 3-7.8 and 8-4 of NFPA 13-1975 ca l l f o r 2 I / 2 - i nch hose valves fo r f i r e department use or the minimum of 500 gpm. Section 8-4 .4 , which does not requ i re tha t ca lcu la ted sp r i nk l e r demand be added, i s r e f e r e n c e d to NFPA 14 which ca l l s f o r a minimum of 500 gpm fo r the f i r s t r i s e r and 250 gpm fo r the second r i s e r wi th a maximum of lO00 gpm fo r a l l r i se rs . In view of the splendid record of supervised automatic s p r i n k l e r systems in e x t i n - guishing or c o n t r o l l i n g f i r e s , 500 gpm hose stream requirements are excessive.

A member of the IAFC and a member of FEMA have reported tha t f i r e departments, in actual p rac t i ce , use l I / 2 - i nch hose tha t d e l i v e r only lO0 gpm from the hose streams.

I t the re fo re seems incons is ten t to requ i re such a high volume of hose stream water when f i r e departments are equipped wi th 1 I / 2 - i nch hose l ines to back up a s p r i n k l e r system in a complete ly spr ink le red bu i l d ing .

Recommendation:

I -7.1

I -7 COMBINED SYSTEMS

I-7.1 A combined system is one where the water p ip ing serves both 1 I / 2 - inch (38 mm) ou t l e t s fo r f i r e department use and ou t l e t s fo r automatic sp r i nk le rs . Such combined systems shal l comply wi th the requirements of NFPA 13-1975 in

regard to the automatic sp r i nk l e r por t ions of the system, and wi th NFPA 14 in regard to s iz ing of v e r t i c a l r i se rs and water suppl ies. When the bu i ld ing is complete ly sp r ink le red , the r i se rs may be sized by hydrau l ic ca l cu la t i ons .

Supporting Comment:

Delete SI un i ts in Paragraphs I - 7 . 1 , I - 7 . 4 , 3-4.1, 3-4.2 and 3-4.3 and A-3-4.1.

Supporting Comment:

Does not meet NFPA-194-1974 Standard fo r Screw Threads and Gaskets fo r F i re Hose Connections.

Committee Act ion:

Accepted wi th mod i f i ca t i on . New sect ions to be added as fo l lows :

I -5 Units. Metr ic un i ts o f measurement in th i s standard are in accordance wi th the modernized metr ic system known as the I n t e rna t i ona l System of Units (SI ) . Two uni ts ( l i t r e and bar) , outs ide of but recognized by SI, are commonly used in i n t e r - na t iona l f i r e p ro tec t i on . These uni ts are l i s t e d in Table I -5 wi th conversion fac to rs .

14

Because of th is establ ished record, hose stream requirements in NFPA 13 (Table 2-2.1(B) should provide adequate back-up to sp r ink le r systems to f i g h t i n t e r i o r f i r e s .

Recommendation:

I-7.2

I -7 .2 The waLer supply fo r a combined system shal l comply wi th the requirements given in Table 2-2.1(B) of NFPA 13-1975.

Supporting Comment:

HARRY W. MARRYATT'S TEXT "AUTOMATIC SPRINKLER PERFORMANCE IN AUSTRALIA (1886 - 1969) is the most re l iable source of data on supervised automatic sprinkler performance known to us. The record (attached) indicates that 66.56% of f i res were extinguished or controlled by one sprinkler. 92.81% by Five or less sprinklers. This was accomplished with water supplies and densities lower than those in the U.S.

Two problems occur in this section:

I. This section imposes additional water supply requirements in a combined sprinkler-standpipe system by requiring that water supplies also comply with Sec. I-7.3 in addition to the normal standpipe system requirements contained in Sec. 5-3.1.

2. Reference is made to water supply requirements contained in Sec. 2-I.2 and 5-3.1. Section 2-I.2 contains pipe size requirements, not water supply requirements.

Recommendation:

I-7.2

Revise Sec. I -7 .2 to read: "The water supply fo r a combined system shal l comply wi th the requirements given in 5-3.1. Exception: When the bu i ld ing is completely spr ink le red, the water suppl ies shal l comply wi th I - 7 . 3 . "

Supporting Comment:

Problem No. I :

There is a subtle but very important change in the verbiage of Sec. I-7.2 as compared to Sec. 142 of the former edition of the standard. Insertion of the word "also" would require that the water supply be sized, both in compliance with I-7.3 and 5-3.1. Obviously, this takes away the credit

183

14

which has been given in p r i o r ed i t ions of the standard in s iz ing the water supply fo r a f u l l y spr ink lered bu i ld ing . Bui ld ings designed under Sec. 14 of the previous ed i t ions of the standard have produced exce l len t service records and no j u s t i f i c a t i o n fo r an increase in the water supply requirements fo r these bu i ld ings is seen.

Problem No. 2:

This is a m i s i d e n t i f i c a t i o n of a reference paragraph.

Committee Act ion:

I Accepted in p r i nc i p l e . Delete "2-1.2 and" in second l ine and "also" in t h i r d l i ne of I -7 .2 as published in the Technical Committee Reports.

Committee Comment:

The Committee agrees wi th th is proposal.

The water supply for a combined system should relate to the actual system requirements irrespective of the size or occupancy of the building.

Recommendation:

8 Submitter:

Edward J. Re i l l y , National Automatic Spr ink le r & Fire Control Assn., Inc.


See Proposal No. 4.

Recommendation:

I -7 .3

DELETE:

REASONS: I . A combination system as defined in I -7.1 can only be i ns ta l l ed in a completely spr ink lered bu i ld ing .

2. Water suppl ies (as proposed) are governed by Table 2-2.1(B), and 8-4.4 of NFPA 13-1975. NAS & FCA intends to submit an amendment to 8-4.4 to make NFPA 13 and 14 conform to water supply requirements of 2-2.1(B).

Supporting Comment:

None.

Committee Action:

Hold for future agenda.

I -7 .3

Revise Paragraph I-7.3 to read: "The minimum water supply for a combined system shall be equal to the sprinkler system design demand plus 250 gpm for inter ior hose use."

Supporting Comment:

Fire wi l l be controlled by the sprinkler systems. Final mop-up wi l l be with hose lines.

The standard contains no definit ion of a l ight hazard or a high rise building. Thus, reference to these types of buildings which are not properly defined by the standard is inappropriate.

Omission of hose in combined systems is not clearly indicated but is "subject to the approval of the authority having jur isd ic t ion" . This is contrary to most major model building codes.

Recommendation:

1-7.4

Retain present wordage in 144 of NFPA 14-1974.

2-I .6

Revise Sec. 2 - I . 6 to read: "Where pumps supply ing two or more zones are located at the same l e v e l , each zone shal l have separate and d i r e c t supply p ip ing of a size not smal ler than the r iser which i t serves. Zones with two or more standpipes shall have at least one direct supply pipe of a size not smaller than the largest r iser which i t serves."

Support ing Comment:

There does not seem to be any reason to cause the s ize of supply pipes to be l a rge r than the s ize of the r i s e r s , because the same f low w i l l occur in both. I f the committee be l ieves tha t excess f r i c t i o n loss may occur in supply p ipes, e i t h e r because they are of excessive length or because mu l t i p l e r i se rs are being f lowed s imul tan- eously, then the sect ion should be rev ised to ref lect the need for increased supply pipe sizes only under those conditions.

In any case i t does not appear tha t there is any j u s t i f i c a t i o n fo r mu l t i p l e supply pipes between a water supply source and the r i se rs in a m u l t i p l e r i s e r system.

Text of 4 - l . l is not strong enough. A l i f e hazard is involved here for f i re fighers and building occupants. The information contained in "A"4 - l . l , second paragraph, should be included as a part of the standard, rather than kept in the appendix where i t has an information only type of impact.

Recommen da t i on :

Supporting Con~ment :

I t only makes sense to try to prevent smoke from f i l l i n g stairway towers used for evacuation. Having hose outlets in stairwells only, forces f i re f ighters to par t ia l l y jam open selfclosing f i re doors with f i re hose when operating at a f i re .

This change w i l l a l low 3/4-inch (18mm) thru l - I / 2 - i n c h (37mm) including f i rm wall garden type hose for use by bu i ld ing occupants (Class I I and I I I services). An inexperienced person can more safely act ivate such a hose, is more l i k e l y to get water on the f i r e sooner in his attempt to ext inguish i t , and create less hazard to himself. Also, small size garden type hose is i n f i n i t e l y more maneuverable in corr idors and of f ices and can e f f ec t i ve l y ext inguish small f i res with less water damage. The hose connection of a standpipe for Class I I I use should be sui tab le for connection of larger hoses by the f i r e department and should be equipped with an eas i ly removed reducing f i t t i n g to adapt to the smaller hose couplings.

The requirement for a minimum 0.250" wall th ick- ness for ver t i ca l piping in Class I and Class I I I systems does not appear to be j u s t i f i e d . This requiremnt precludes the use of Schedule 40 pipe in pipe sizes 4" and smaller. In addi t ion, the hor izontal bulk feed piping for a standpipe system located at the base of the standpipe r isers may have a thinner wall thickness than the ver t i ca l standpipes.

Recomendation:

6-3.1

l Revise Sec. 6-3.1 by delet ing the statement: "Vert ica l pipe in Class I and I I I systems shal l not be less than 0,250 (6.4mm)" thickness," 197

Table 6-3.1 (Page 14-20) should not be l im i ted to: Welded Seamless Pipe, ASTM A 120-73. Asterick references "Standard Wall" Schedule 40 Pipe permitted for pressures up to 300 P.S.I. Schedule 30 Pipe acceptable in sizes 8 inch and larger.

Paragraph 6-3.1 states wall thickness not less .250. This excludes 4" Schedule 40, which has a nominal wall thickness of .237 (Sch. 80 is .337).

Recommendation:

Section 6-3.1

Refer to NFPA 13, I ns ta l l a t i on of Spr inkler Systems 1975, Paragraph 3-1.1.2 and 3 - I .1 .3 , al lowing usage of E.R.W. pipe having wall thickness of .188 for sizes 4 through 8 inches and .120 for sizes 2 I /2" through 6". Such wall thickness is permitted for pressures up to 300 P.S.I.

I f a f i r e department pumper connects in to such a standpipe you could expect minimum pressures of at least 150 psi . Therefore the system must be capable of wi thstanding at leas t 150 psi wi thout damage or breakage. Refer to N.F.P.A. No. 13-I-11.

Supporting Comment:

During recent years standpipe fa i l u res have been occurr ing at an alarming rate resu l t ing in substant ia l f i r e losses and excessive operat ional delays. Decreased f i r e department manning necessitates a high degree of standpipe r e l i a b i l i t y .

The t i t l e is "Propr ie ta ry Supervisory Service Systems" but the word "Propr ie tary" is not def ined w i th in the standard. A d e f i n i t i o n is shown in NFPA 72D "Propr ie tary Protect ive Signal ing Systems" but fo r your purpose, i t is not cor rect . Also you do not c i t e NFPA 71.

Sprinkler Systems can be rendered in effective by incidents of vandalism, accidents, or small fires which only affect one or two sprinklers out of a complete system.

Recommendation:

7-3

7-3 Whenever possible emergency individual sprinkler shutoffs should be available for temporary use in case. of accidents, vandalism, or small f i re situations. This allows the sprinkler system to remain primed and effective while arrangements can be made to replace expended sprinkler heads. This also has the additional advantage of limiting the necessary access to locked sprinkler shut off valves to only those in charge of f i re protection and allows anyone else to correct an errant sprinkler without significantly reducing the effectiveness of the sprinkler system.

Supporting Comment:

My 15 years experience with the Alhambra Fire Department has convinced me of the need to pay more attention to situations which can disable a sprinkler system. In public places i t is often impossible to immediately replace an errant sprinkler head, therefore, the whole sprinkler system is disabled and i t ' s protection lost until repairs can be conviently accomplished. This Situation must be avoided i f sprinkler systems are to be relied upon for public safety.

Committee Act ion:


Committee Comment:

This proposal const i tu tes new mater ia l . The Committee feels that th is mater ia l is more app l ica- ble in NFPA 13E, Recommendations fo r Fire Depart- ment Operations in Properties Protected by Sprinkler Systems, and wil l be considered at the time of the next revision.
