This list ~ e s e n t s the r~mbership at the time the Comraittee was balloted on the text of this edition. Since that time, changes in the membership may have occurred.

Committee Scope: Standards for the installation of portable fire extinguishers and equipment and recommended practices for the maintenance and use of these devices. Does not apply to perma- nendy installed fire extinguishing systems even though portions of those systems areportable, such as hose and nozzles which may be attached to a fixedsupply of extinguishing agent.

The Report of the Committee on Portable Fire Extinguishers is presented for adoption in 2 parts.

Part I of this Report was prepared by the Technical Committee on Portable Fire Extinguishers and proposes for adoption amendments to NFPA 10-1990, Standard for Portable Fire Extinguishers. NFPA 10-1990 is published in Volume 1 of the 1993 National Fire Codes and in separate pamphlet form.

Part I of this Report has been submitted to letter ballot of the Technical Committee on Portable Fire Extinguishers which consists of 21 voting members; of whom 12 voted affirmatively, 2 negatively (Messrs. Lonabaugh and Serapi~lia), and 7 ballots were not returned (Messrs.Fledller, Flermng, Harrington, Hoeppner, Kraus, Miller, and Wright ).

Mr. Lanabangh voted negatively stating: ~Log #130, disagree with Committee Action - Production of a

hermetically sealed Halogenated agent fire extinguisher is achiev- able. Log #127 and #133, disagree with Committee action. I supervise the maintenance of 10,000 cartridge operated fire extinguishers and have no evidence to support the proposed requirement. This would force us to eliminate hand portables wherever possible."

Mr. Serapiglia voted negatively stating: Log #130 and Log #131, I understand two manufacturers have

completed all the UL requirements for listing a hermetically sealed halon 1211 fire extinguisher with a 20 year service life. Not recognizing this is inappropriate."

Part II of this Report was prepared by the Technical Committee on Portable Fire Extinguishers and proposes the withdrawal of NFPA 10L-1990, Model Enabling/get for the Sale or Leasing and Servicing of Portable F'n-e Extinguishers. NFPA 10L-1990 is published in Volume 9 of the 1993 National Fire Codes and in separate pamphlet form.

Part II of this Report has been submitted to letter ballot of the Technical Committee on Portable lrtre Extinguishers which consists of 21 voting members; of whom 14 voted affirmatively, and 7 ballots were not returned (Messrs. Flediler, Fleming, Harrington, Hoeppner, Krans, Miller, and Wright ).

Hermetically Sealed Halogenated Agent Fire Extinguisher. A nonrechargeable extinguisher using a halogenated agent in which both the extinguishing agent and expellant gas (if any) are contained in a single cylinder by use of a factory-installed hermetic seal, and which includes an indicating device external to the cylinder that provides a visual indication when the seal has been broken. SUBSTANTIATION: Portable halogenated fire extinguishers we currently Use have been found to leak at a rate of approximately 1.0 to 2.0 ounces per year. An extinguisher provided ~bith a hermetic seal has an inherent leakage rate substantially less than extinguishers with other types of seals. This characteristic can be used advanta. geously, parucularly in halogenated agent extinguishers making the establishment of a separate category desirable.

Explicit is the notation that any penetration of the cylinder usin~ nonhermetical seals must be elinunated, while maintaining an abdity to identify visoally an extinguisher having a punctured seal. COMMITrEE ACTION: Reject. COMMITrEE STATEMENT: The proposed term is not in the standard currently.

SUBSTANTIATION: European and ISO standards do not distinguish between "dry chemical" agents and "dry powder" agents. Their use of the term "dry powder" includes both dry chemical and dry powder as defined in this standard. COMMITTEE ACTION: Accept-

(Log #15) 10- 41 - (1-3 Gauges (New)): Reject SUBMITIT.R: WalterJ. Held, Hrebuster Corp. RECOMMENDATION: Add the following new Definition:

Gauges. Each gauge shall receive a gauge test every three years to determine accuracy. SUBSTANTIATION: Many stored pressure fire extinguishers have insufficient operating pressure which is partly due to inaccurate gauges. This problem is verified when gauges are tested using test method developed by former NTPA 10 Technical Committee member, AI Krulee, engineer. COMMITrEE ACTION: Reject. COMMITrEE STATEMENT: The recommended text is not a definition.

(LOg #16) 10- 42 - (1-3 Weighing (New)): Reject SUBMI'ITEI~ WalterJ. Field, Firebuster Corp. RECOMMENDATION: Add the following new Definition: Weighing. All fire extinguishers shall be weighed with an accurate

scale that is tested and calibrated on an annual basis. Scale graduations shall be shown in 1 /4 lb increments for most uses and shown in less than 1 /4 lb graduations for the smaller capacity extinguishers. SUBSTANTIATION: The type of scales being used in the field ~ ~ ~ C T I t allow for an accurate weighing of the total weight.

( Log #i 7) 10- 43 - (i-3 Weighing (New)): Reject SUBMITTER: WalterJ. Held, Hrebuster Corp. RECOMMENDATION: Add the following new Definition: Weighing. Each fire extinguisher that is in service shall have

correct weight information placed on extinguisher. Both the full weight and empty weight needs to be provided on an affixed weight label. SUBSTANTIATION: Many fire extinguishers that are in service lack adequate weight information on the label. This creates a problem for correct inspection and maintenance procedures. COMMITTEE ACTION: Reject. COMMITIY~ STATEMENT: The recommended text is not a definition.

(Log #1) 10-44- (1-4): Reject SUBMITTER: Paul ASeguin, Rome, NY RECOMMENDATION: Add new text to read as follows:

~Portable fire extinguishers will comply with the color code stated in this standard as follows:

1. CO-2 Types - Color Black 2. Dry Chemical Types - Color Blue 3. Water Types - Color Red 4. Halon Types - Color Limegreen 5. Foam Types - Color Beige--

SUBSTANTIATION: Presently there is no standard that covers what color a fire extinguisher should be, as a result fire extinguishers come in many colors. However, most extinguishers do come in the color RED, no matter what type of agent is inside, this can be confusing to some people that several types in there work center, requiring them to take time to read the label (the right extinguisher for the right type of fire) when time is critical. - - -

Introducing a standard that requires all fire extinguishers to be color coded will make it simple for the public to recognize the type of agent inside the fire extinguisher. COMMrITEE ACTION: Reject. COMMrrTEE STATEMENT: The color coding of extinguishers is outside scope of the standard.

(Log #'29) 10-45- (1-4.3): Reject SUBMITTER: Paul O. Huston, Amerex Corporation RECOMMENDATION: Revise text to read as follows:

1-4.3 Portable fire extinguishers should meet or exceed all of the requirements of one of the fire test standards and one of the a ro riate erformance standards shown below.

~Pl ~ r e TePs~standard:ANSI/UL 711 (b) Performance Standards

1. CO 2 Types: ANSI/UL 154 2. Dry (~emical Types ANSI/UL 299 3. Water Types: ANSI/UL 626 4. Halon Types: ANSI/EL 1093 5. F'llm FonfdngTypes: ANSI/EL 8

1-4.3.2 Extinguishers installed in Canada should meet the following Canadian Standards:

(a) Fire Test Standard: CAN/ULC-SS08-M90 (b) Performance Standards

1. CO 2 Types: CAN/ULGS503-Mg0 2. Dry Che/nical Types: CAN/ULC-S504-M88 3. Water Types: CAN4-SS07-M38 4. Halon Ty~pes: CAN/ULGS512-M87.

SUBSTANTIATION: The Canadian Regulations and Authorities only recognize equipment approved to Canadian National Standards as meeting fire protection requirements. Equipment approved to American National Standards Institute ANSI/UL standards are not acceptable for compliance to Canadian regulations. Canadian fire test standards and equipment performance standards axe different than the ANSI/UL standards. The Canadian fire protection industry has indicated the intent of adopting the International Standards Organization (ISO) Standards when theyare issued. By separating the Canadian and ANSI Standards into two specific jurisdictions each jurisdiction can adjust the standards references to comply with his close at hand experience commensurate with his own national laws and regulations without compromising the other Jcurisdictions regulations.

COMMITTEE ACTION: Accept.

(Log #13) 10- 48 - (1-5.2): Reject SUBMITTEI~Joseph Bloom, Bloom Fire Investigation RECOMMENDATION: Add the word "motorhomes. ~ SUBSTANTIATION: This i to include motorhomes into the ordinary(moderate) hazard, thereby requiring a 10 B:C extinguisher. At present, a 5 B~C is the only requirement for motorhomes byNFPA501C. Motorhomes-carry 50+ gai of gasoline , 20+ gal of propane, are subject to transmission boil-overs and fuel leak~.

The Uniform Hre Code, Section 79-908, requires a 20 B:C extinguisher at service stations. U.S. DOT, Federal Motor Carrier Safety Regulations Handbook, Section 393.95(2) (i), requires commercial trucks to carry a minimum 10 C extinguisher.

By placing motorhomes into the "ordinary ~ hazard category, a 10 B:C extinguisher will be a realistic minimum standard, considering the size, construction, and amount of flammables or combustibles carried on board. COMMITIW~ ACTION: Reject. COMMrIWEE STATEMENT: The proposed change is outside the scope of the standard. (See NFPA 501~ )

(Log #20) 10- 86 - (Table 3-2.1): Reject SUBMI'I'rER= Lyman L. Parks, P.E., BeUcore RECOMMENDATION: Add three asterisks (***) next to 2-A under the "Light Hazard Occupancy" heading in Table 3-2.1 and add new note to Table 3-2.1 as follows:

"Two 1-A rated extinguishers may be used to fulfill the requirements of one 2-A rated extinguisher for alterations or re-spacing of existing units." SUBSTANTIATION: Several jurisdictions have rendered conflicting interpretations on the use of 1-A rated extinguishers for light hazard occupancies. Section 3-2.1 can be interpreted to permit 1-A rated units when more than one unit is required, i.e., large spaces. Since Section 3-2.1.1 excludes A capable but not 1-A rated extlnguishers, by inference, I-A rated units should be acceptable ff Table 3-2.1 conditions are met for multiple unit locations. Example 3, in Appendix E-3-9 fits the case and bears out the interpretation. The problem arises with Appendix Table E-3-4 which shows no sq ft for 1- A rated extinguishers. Even though paragraph E-3.4 relates the Table to "protected by one extinguisher", it has been interpreted as prohibiting 1-A rated extinguishers.

The proposed Section would clarify the matter in the body of the standard. With the impendingreplacement of Halon 1211, this change will clarify the acceptability of retaining 1-A rated extinguishers until new units and /o r agents are available. In the over 6000 locations covered by Bellcore's Client Companies (7 Regional Telephone Companies), our experience with these units has been excellent and we would like to use them until the replacement for Halon is approved and available, without problems of interpretation. While the primary concern is for A-1 Haion, we feel there should be no problem with 1-A rated dry chemical either. COMMIqi'rEE ACTION: Reject. COMMITTEE STATEMENT: The change grew out of the "Novice fire tests series," and the justification for maintaining it at 2Awould undoubtedly be the same today. A number of people that were on the Rating Subcommittee and conducted the Novice tests are still on the committee today. Based on this series of tests, the committee feels the current minimum requirement isjustfied.

"Extinguishers shall be subjected to maintenance not more than one year apart, at the time of hydrostatic test, or when specifically indicated by an inspection. SUBSTANTIATION: As the standard now reads, (1990 edition) one could interpret Chapter 4 as not requiring full maintenance Of Carbon Dioxide and Pressurized Water extinguishers at any time. Paragraph 44.1 states that all extinguishers ~ be subject to

maintenance at least once a year and that the procedure shall be in accordance with Paragraph 4-4.2.

Paragraph 44.2 stat~ that the maintenance shall include a thorougfi examination of (a) Mechanical Parts - (b) extinguishing agent- (c) expelling means. It further goes on to exclude an i~ternal ~ < ~ n of Carbon Dioxide and Stored Pressure extinguishers. Paragraph 44.1.3 basically states that those extinguishers previously exduded (C33-2) & Stored Pressure Types) from internal examination AND WHICH REQUIRE A 12 YEAR HYDROTEST, should be emptied every six years and be given full maintenance. (In today's market this would cover only the stored pressure dry chemical and Halon extinguishers.) As we know, Carbon Dioxide and the Stainless Steel Stored

Pressure Water extinguishers require Hydrostatic test every 5 years. Therefore they were excluded from FULL INTERNAL maintenance per the exception to Paragraph 44.2 and not effected by Pm'-agraph 4-4.1.3. The net result is that there is NO requirement for full maintenance of these two type extinguishers within the requirements section of this document. COMMrIT££ ACTION: Accept.

SUBSTANTIATION: The Authority HavingJurisdiction and the end users are generally unaware of the conducdvhy test requirements on CO 2 fire extinguisher hose assemblies. In addition, there are many distributors who are also unaware or choose to ignore this requirement. The requiring of a label on the hose will make everyone cognizant of this requirement.

Why must the halon be removed from a rechargeable extinguisher if they have not lost their charge or weight?

COMMITIT~ STATEMENT: Too restrictive there are other acceptable methods for indicating internal maintenance.

(Log #132) 10-124 - (4-4.1.5): Reject SUBMITTER: James Soteriades, Whitehall Fire Department, OH RECOMMENDATION: Revise: ... When the applicable maintenance procedures are performed during periodic recharging or hydrostatic testing, the six-year requirement shall begin from that date.

To: ... Applicable maintenance procedures shall be performed whenever the extinguisher valve is removed during periodic recharging or hydrostatic testing. The six-year requirement shall begin from that date. S ~ A h r r l A T I O N : Performance of complete maintenance during recharging is a reasonable measure for ensuring peak performance for the fire extinguisher. Since the valve is already removed, there is no reason not to perform maintenance.

This minor change can improve fire extins[uisher reliability with very little additional effort on the recharger s part. I understand that most recharge companies already "label" after recharging. The proposed change will provide standardization of this practice. COMMITrER ACTION: Reject. COMMITTEE STATEMENT: Topping offis permitted.

(No change to the rest of the paragraph). SUBSTANTIATION: A Formal Interpretation for NFPA 10 essentially states that it is not the intent to require a cartridge operated extinguisher to be emptied of dry chemical agent when doing an annual maintenance. This would allow the extinguisher to go l~years to hydrotest time before a thorough internal inspection was made. The proposal wording would result in a requirement to empty a cartridge operated extinguisher and thoroughly inspect the agent and the shell interior at 6 year intervals.

COMMITrRE ACTION: Accept in Principle. Add the following as a new Section 4-4.1.'5 and renumber existing

sections according]T. "Pressure regulators provided with wheeled type fire extinguishers

(Log #18) 10-127- (44.1.5 Exception): Reject S U B - - R : Gary E. Cooper, Inter-Island Fire-Safe Co. RECOMMENDATION: Add to NFPA 10, 4-4.1.3, 1990 edition an exception requiring non-reachargeable extinguishers to be removed from service at a maximum of twelve (12) years. I believe the wording causes some confusion. People seen to interpret i t differently.

Some extinguishers dearly state in the owners manual that the non- reachargeable extinguisher shall be discarded after six (8) years. Note that six (6) years is also the limit of the manufacturers warranty on some extinguishers. There seems to be a feeling that NFPA 10 would supersede the instructions in the owners manual.

I would suggest that the wording in the exception to be changed to: Exception: Non-rechargeable extinguishers shall not be hydrostati-

cally tested but shall be removed from service as directed by the manufacturer's instructions, not to exceed a maximum interval of twelve (12) years from the date of manufacture. Non-rechargeable halogenated agent extinguishers shall be disposed of in accordance with 4-5.5.5. SUBSTANTIATION: Many of these extinguishers are inexpensive models, often sold at discount stores, have a high failure rate and often wind up in boats, over the road vehicles and commercial applications.

It is my opinion that these extinguishers should not be left in service beyond the manufacturers warranty limits. The NFPA 10 standard of twelve (12) years puts the service technician in a position of assuming liability for equipment that he must certify, but is not properly able to check. In many cases the only difference between a ~erv~ceable extinguisher and a disposable extinguisher is the wording on the gange "do not recharge." If the manufacturer is willing to extend the warranty to twelve (12) years then there would be a sharing of liability for malfunction.

Also, disposable extinguishers should clearly shown on the label the recommended date of disposal.

It is also my opinion that many of these extinguishers should be dxaXig marketed for residential use as the construction does not lend itself to the abuses of temperature extremes, weather and heavy vibration found in non-residential applications. COMMITrE£ ACTION: Reject.

Editorially change "remove from service" to "remove from use." COMMITrEE STATEMENT: Existing text adequately covers the minimum requirement.

(Log #131) 10-128 - (4-4.1.5 Exception No. 1 and Exception No. 2 (New)): Re'ect S ~ ' I I ~ r E R : U Dean Arrington, AT&T RECOMMENDATION: Renumber and revise existing Exception tO Section 4-4.1.5 to read:

Exception No. 1: Nonrechargeable extinguishers other than halogenated types shall not be hydrostatically tested but shall be removed from service at a maximum interval of 12 years from the date of manufacture. Add Exception No. 2 to Section 4-4.1.5: Exception No. 2: Nonrechargeable halogenated agent extinguish-

ers other than hermetically sealed extinguishers shall be removed from service at a maximum interval of 12 years from the date of manufacture and disposed of in accordance with 4-3.3.3. Hermeti- cally sealed halogenated agent extinguishers designed for 20 years of service and marked accordingly shall be removed from service at a maximum interval of 20 years from the date of manufacture and disposed of in accordance with 4-3.3.3. SUBSTANTIATION: Portable halogenated fire extinguishers we currently use have been found to leak at a rate of approximately 1.0 to 2.0 ounces per year. An additional unknown amount is released during required maintenance and testing. Cumulatively, this represent what we consider to be an unacceptable discharge of an ozone depleting agent into the atmosphere.

Engineering documentation provided by manufacturers states that hermetically sealed extinguishers have been and can be designed for a minimum of 20 years of service without a requirement for breakdown maintenance or hydrostatic testing.

298

Any corrosion or damage that occurs to the exterior of the extinguisher would be identified by periodic inspections required by Section 4-3.

The U.S. Government purchased approximately 125,000 hermetically sealed halon 1501 extinguishers m the early 1970's which have been successfully deployed for more than 20 years. Related versions of hermetically sealed units have been utilized successfully in other forms: CO 2 cartridges for inflatable rafts and dry chemical extinguishers, nitrogen cylinders for submarine torpedo recovery systems and for inflating aircraft escape slides, and halon 1301 extinguishing systems for extinguishing fires in aircraft engine nacelles.

Note: Supporting material is available for review at NFPA Headquarters. COMMITTEE ACTION: Reject. COMMITTEE STATEMENT: There currently are no non-rechargeable hermetically sealed halogenated agent extinguishers listed. Additionally, there is no data to support the 20 year provision.

"Extinguishers out of service for maintenance or recharge shall be replaced by spare extinguishers of the same type and at least equal rating by the service company performing the work." SUBSTANTIATION: As it is worded now it doesn't say who has to provide the replacement extinguishers, the customer or the service company. In some cases a customer could be left without fire protection. COMMITrEE ACTION: Reject. C O ~ STATEMENT: The Committee cannot dictate who

seal shall be removed by operating the pull pin or locking device. After the applicable maintenance procedures are completed, a new tamper sealshail be installed. SUBSTANTIATION: It is quite often difficult to visually or mechanically ascertain if the pull pin is bent, corroded or binding, or if the operating lever is damaged without removing the pull pin or other valve locking device. This assures that the locking device has been inspected and will work properly when the extinguisher is needed. This procedure has been recommended in the service manuals of some manufacturers. COMMITTEE ACTION: Accept in Principle. Add the following as 4-4.2.1: "Seals or Tamper Indicators. At the time of the maintenance, the

tamper seal of rechargeable fire extinguishers shall be removed by operating the pull pin or locking device. After the applicable maintenance procedures are completed, a new tamper seal shall be installed." COMMrITEE STATEMENT: Editorially revise proposed wording and properly located it.

"Extinguisher shells of the low pressure type that pass applicable internal maintenance procedures shall have the test information recorded on a suitable metallic label or equally durable material a minimum of 2 in. x 3 1 /2 in. The label shall be affixed to the shell by means of a heatless process. These labels shall be self-destructive when removal from an extinguisher is attempted. These labels shall include the following information:

(a) Month and year the test was performed, indicated by a perforation such as by a hand punch.

(b) Name or initials of person performing the test, and name of agency performing the test.

(c) All print shall be in black on a light blue background." SUBSTANTIATION: It is common practice for a fire equipment distributor to affix a label to the extinguisher after performing an internal maintenance procedure, but there is no direction in the standard regarding the type of label. The label described will be distinctive and not confused with the hydrotest label. COMMITrEE ACTION: Accept in Principle.

1. Revise 4-4.1.3 to read as follows: "Fire extinguisher shells that pass the applicable six year require-

ment of 4-4.1.3 shall have the test information recorded on a suitable metallic label or equally durable material a minimum of 2 in. x 3 1/2 in. The label shall be affixed to the shell by means of a heatless process. These labels shall be self-destructive when removal from an extinguisher is attempted. These labels shall include the following information:

(a) Month and year the test was performed, indicated by a perforation such as by a hand punch.

(b) Name or initials of pecson performing the test, and name of agencyperforming the test."

2. Add the following appendix material: A-4.4.3.1 Labels should be printed in black with a light blue

(LOg #88) 10-133 - (4-4.3.1): Accept in Prindple SUBMYIq'ER: Norbert W. Makowka, NAFED RECOMMENDATION: Add the following to section 4-4.3.1:

"In addition to affixing an internal maintenance label to the shell of a fire extinguisher, a permanent legible marking of contrasting color at the top of the s ~ h o n tube shall be made indicating the - following information:

(a) Month and year the internal maintenance was performed. (b) Name or initials of person performing the internal mainte-

nance and the name of the agency." SUBSTANTIATION: Unscrupulous fire equipment companies quite often charge their customers for performing a 6-year full maintenance and internal inspection on a pressurized fire extinguisher without doing so in accordance to the NFPA 10 standard. This practice can result in many fire extinguishers being inoperative and create a dangerous element in the first line of fire defense.

Fire Marshals, Fire Chiefs, and Fire Inspectors are aware of this fraudulent service being performed, consequendy, many states have passed laws requiring that in addition to a 6-year internal maintenance label affixed to the shall, a label shall be affixed to the syphon tube or the syphon tube is marked. COMMrlTEE ACTION: Accept in Principle. Add the following to 4-4.3.1: "In addition to affLxing a label to the shell, rechargeable dry

chemical fire extinguishers shall have an internal legible marking to indicate the following:

(a) month and year the maintenance was performed (b) name or initials of person performing the maintenance and

the name of the agency." COMMITI~E STATEMENT: Internal marking is necessary for verifying that internal maintenance was performed.

It is extremely important to remove any water or moisture from any extinguisher before recharging. Excess moisture in a dry chemical extinguisher will cause the agent to cake and lump and become unusable, plus cause corrosion to the extinguisher shell and valve. In carbon dioxide and halon extinguishers, excess moisture will cause extremely corrosive acids to form when combined with the extinguishing agent and corrode the extinguisher shell and valve.

Exception: Water type extinguishers do not have to be dried prior to recharging. SUBSTANTIATION: The proposed wording stresses the importance of drying extinguisher shells and gives the reasons why it is important.

4- (5-1.1 through 5-2): Reject ~%| SUBMITTER: Gary K. Cooper, Inter-Island Fire-Safe Company | RECOMMENDATION: I feel that NFPA should at the very least publish an advisory in the next revision of NFPA 10. This advisory should be at least as complete as the NAFED pamphlet "When Fire Extinguishers are Dangerous"

I would like to suggest that NFPA publish a "Do Not Service" alert for the affected extinguishers. Pictures and /o r examples would be most effective.

Some extinguishers ~ a t are apparently on the problem list are: 1. An£ water extinguisher manufactured prior to 1970. Many were

manufactured of dis-similar metals (i.e. brass necks and stainless steel shells). In 1971 the burst and rupture specifications were revised, and the type of stainless steel was changed.

2. &lax stainless steel dry chemical extinguisher pressurized or cartridge operated.

3. ~ mild steel shell with brass neck.

SUBSTANTIATION: The above standard section numbers detail the maximum life of certain extinguishers that will expire December 29, 1992. Since many of these extinguishers still exist and since there is always a certain percent of interested parties that never seem to get the word, I would like to suggest that NFPA publish a "Do Not Service" alert for the affectedextinguishers. Pictures and /o r examples would be most effective. Separate from the above is an issue that causes me great concern.

In 1984, NAFED _published a pamphlet tided "When Fire Extinguish- ers are Dangerous. This pamphlet, if the information is correct, discusses various types of extinguishers that should be removed from service wi~out a phase out period. Examples are given of extinguishers that have caused death (a fire fighter), serious injury; or because of now known design and construction flaws have great potential for causin . Ig injury .. .

I have spent considerable Ume this past year trying to get information andhave received almost nothing.

U.L. has not returned any telephone calls. General Fire Extin- guisher Company, whose extinguisher is pictured in the pamphlet, denies, in telephone conversations, that there is anything wrong with their older units. General sales representative states he has no knowledge of anything that is a safety problem and has twice promised to check into it and call me back.

I have been able to extract some indication that there is more of a problem by asking questions like "If you were a fire extinguisher service company would you certify "blank" and then name the type of extinguisher." This type of question elicits a negative response. Some extinguishers that are apparendy on the problem list are: 1. ~ water extinguisher manufactured prior to 1970. Many were

manufactured of dis-similar metals (i.e. brass necks and stainless steel shells). In 1971 the burst and rupture specifications were revised, and the type of stainless steel was changed.

2. ~ stainless steel dry chemical extinguisher pressurized or cartridge operated.

3~ILY mild steel shell with brass neck. I realize that NAFED is not a policy making organization; however,

they do have a membership to be responsible to. It is my experience that they are very careful with their advisories. If, however, there has been a published problem since 1984 and NFPA has not acknowl- edged it or reacted, then I feel this borders on the edge of being criminal.

I feel that NFPA should at the very least publish an advisory in the next revision of NFPA 10. This advisory should be at least as complete as the NAFED pamphlet "When Fire Extinguishers are Dangerous." COMMrrFEK ACTION: Reject.
