(Log #211) 1901- 2 - (Entire Document) : Reject SUBMITTER: Steve Morelan, Litde Canada Fire Depar tment , MN COMMENT ON PROPOSAL NO: 1901-172 RECOMMENDATION: Divide the gtandard into four separate s tandards (1901, 1902, 1903, 1904). SUBSTANTIATION: Proposed draft is difficult to follow. Four separate s tandards are more user friendly. COMMITTEE ACTION: Reject. COMMITTEE STATEMENT: The Commit tee has combined d~e four document s to ,assist persons who have a need for a s tandard not only for single f imction fire apparatus but for the multi-function fire apparatus dlat many communi t ies are purchasing. Chapter 2 and Table 2-2.2 give a user the necess:wy references to identify die chapters that are required for a p u m p e r (currendy covered by NFPA 1901), an initial attack fire apparatus (currently covered by NFPA 1902), a mobile water supply fire apparatus, (currently covered by NFPA 1903), mad_ aerial ladder or elevating platform fire apparatus (currendy covered byNFPA 19041. In addition, the commit tee has identified the required chapters not only for special service fire apparatus which is no t currently covered in any of the four documents , but has provided a s tandard that will allow its use as die basis of requi rements for any unique type of fire apparatus that a communi ty may want to purchase to suppor t a specialized fimction.

passengers, appliances, or e q u i p m e n t related to o ther than control. If a c~ab or cowl is included, dre designat ion sh,ail be motor vehicle eb~L~sis with cab or cowl.

B. Webster defines dais ,and definit ion is design restrictive. COMMITTEE ACTION: Accept.

(Log #152) 1901- 10 - (1-5 Class B Fires (New)): Accept SUBMITTER: Mark Haider, Waterous C ompany COMMENT ON PROPOSAL NO: 1901-172 RECOMMENDATION: Add definit ion of Class B Fires. Refer to NFPA I 0, 1-3:

"Class B Fires. Fires in f lammable liquids, oils, greases, tars, oil-base )alnts, lacquers, and f lammable gases." UBSTANTIATION: For clarification arm definition. Tile te rm

"Class B Fires" is used in the definit ion of (3lass B Foam. COMMITTEE ACTION: Accept.

(LQg #217) 1901- 11 - (1-5 Close-offPressure): Accept in Principle SUBMITTER: Gerald Dit tmann, Waterous Co. COMMENT ON PROPOSAL NO: 1901-172 RECOMMENDATION: Change the term "close-off" to "shut-off" and define ,xs follows:

Shut ()ft. The condi t ion of zero flow where no l iquid is flowing th rough the p u m p (,all discharge outlets closed) but tire p u m p is pr imed and runn ing .

Shut Off Pressnre. Tile condit ion of zero flow where no liquid is flowing th rough tile p u m p (all discharge outlet~s closed) but the p u m p is p r imed and running .

Max imum Shut Off Pressure. The ne t p u m p pressure obta ined by the pump operat ing u n d e r shut off condit ions with the driving engine operat ing at m a x i m u m governed speed. This pressure is to be de te rmined with the p u m p in dte series (pressnre) position for

~ uinps of the series/paral lel type. UBSTANTIATION: Present definit ion may cause confilsion in

de te rmin ing a m a x i m u m rated speed. The te rm "close off ' is no t consistent with the broader p u m p industry, bu t unders tandable to avoid any confnsion with shut t ing off tile p u m p or engine.

The existing definit ion refers to "m,3.ximum rated obtainable speed" which is undef ined in d)e sense that pumps are not presently rated b~Lsed on speed. Also, the accepted term for this condit ion ,as set forth by the Hydraulic Institute is "shnt off pressure." My suggestions on the rewording of this definit ion is based on the Hydraulic Institute Standard. COMMITTEE ACTION: Accept in Principle.

Change the existing definit ion of close off pressure to: Maximum Pump Close-off Pressure. Tile m~x i mum p u m p

discharge pressure obtained with all discharge outlets closed, with the p u m p pr imed and runn i ng with the p u m p drive engine operat ing at m a x i m u m obtainable speed, andwi t h tile p u m p intake pressure at a tmospher ic pressnre or less. Multistage series/parallel t)umnps:'s are me-Lsured, with tile p u m p in the. p ressure, (series). setting. COMMITTEE STATEMENT: The Commit tee feels that def ining the term "ntaximum p u m p close-off pressure" eliminates the confnsion which may have been caused by the term close-off pressure and its definition. The term m a x i m u m p u m p close-off pressure is used in paragraplt 12-6.3 and 13-5.4. The revised definit ion clarifies tile commit tees in tent of dlose two paragraphs. T he comnfit tee does not in tend d~e definit ions of this s tandard to necessarily fit tile "broader p u m p industry."

(Log #234) 1901- 12- (1-5 Combina t ion Vehicle (New)): Accept SUBMITTEI~ James A. Salmi, Simon Ladder Towers COMMENT ON PROPOSAL NO: 1901-172 RECOMMENDATION: Add definition:

J RECOMMENDATION: Revise text to read as follows: "Compressed Air Foam System (CAFS). A foam.., compressed air

source, pre~snrized source of foam solution and discharge hardware." SUBSTANTIATION: Some CdkFS units do not use a water [Sump to pressurize fo:ml solution. Some use compressed ,air to pressurize foam solution. COMMITTEE ACTION: Accept.

(Log #196) 1901- 14- (1-5 Discharge Out le t Size and Intake Connect ion Size): Accept in Principle SUBMITTER: Steve Morelan, Waterous Co. COMMENT ON PROPOSAL NO: 1901-172 RECOMMENDATION: In the definit ions of "Discharge Outlet Size" and "Intake Connec t ion Size," replace the word "from" with "nearest." SUBSTANTIATION: Clarifies in tent of definitions. COMMITTEE ACTION: Accept in Principle.

Delete the words "available to the p u m p operator" f rom both definitions. COMMITTEE STATEMENT: The Commit tee feels the deletion of dm wording will mee t the in tent of the snbmitter.

(Log #153) 1901- 15 - (1-5 [)rain Time): Accept SUBMITTER: Mark Haider, Waterous Company COMMENT ON PROPOSAL NO: 1901-172 RECOMMENDATION: Revise definit ion of "Drain Time:"

"The t ime period it takes for a specified percent of the total solution contained in file foam to revert to liqnid and to drain out of the bubble structnre." SUBSTANTIATION: Drain t ime is a period of t ime no t a rate. Refer to NFPA 298, 14. COMMITTEE ACTION: Accept.

(Log#151) 1901- 16- (1-5 Eductor): Reject SUBMITTER: Mark Harder, Waterous Company COMMENT ON PROPOSAL NO: 1901-172 RECOMMENDATION: Revise definit ion of "Eductor:"

"A device in tire water line that uses file venturi principle of reducing static pressure at a t a r t a r to in t roduce a proport ionate

~ uantity of foam concentrate f rom storage into the water stream." UBSTANTIATION: Clarification. Original definit ion assumes

foam concentrate is at a tmosphere pressure. COMMIT[EE ACTION: Reject. COMMITTEE STATEMENT: Atmospher ic pressure is what makes an eductor work.

"No gauge or ins t rument shall be more than 89.5 in. (2275 mm) above the level where the operator s tands to read the ins t rument ." SUBSTANTIATION: The 72 in. requi rements does no t have any apparent basis. The intent here is to ensure that the gauges or ins t ruments are readable by the operator. According to Section 7.2 of the book on " H u m a n Engineer ing Guide to Equ ipment Design," viewing distance is l imited by reach distance and should not exceed 29.50 in. According to Sidney L. Smith in an ,article in H u m a n Factors, v 21, n 6, Dec. 1979, p 661-670, "The legibility of displayed letters depends on their size, or more accurately, their sub tended visuM angle at any viewing disumce. Current design standards r e c o m m e n d letter heights in the range from 0.003 to 0.007 rad ( 10 to 24 rain of arc) for good viewing conditions, with 0.0015 t ad (5 min) considered a lower limit based on normal visual acuity.

"...,and allow higher capacity from heaters .and/or air- conditioners." SUBSTANTIATION: This wording can help educate operators about the need for increased engine speed to flow more coolant for beat or to turn compressor(s) at a higher speed to increase cooling capacity. COMMITrEE ACTION: Accept in Principle.

Change tile first sentence of 8-2.1.4 to read: "An engine speed control device shall be installed to allow an

increase in die engine speed when file apparatus is parked." Revise die appendix to A-8-2.1.4 to read: "An increase in engine speed provides increased alternator output,

increased engine cooling, increased air conditioner output, and increased output or performance from other devices which derive their power from die cbassis engine. The intent of the interlock is to ensure that the chassis engine speed cannot be advanced widlout disengaging tile driving wheels of the appa~ttns either at die transmission (having it in park or neutral) or by having a split shaft PTO fully engaged in die correct position to drive the component." COMMITI'EE STATEMENT: The Committee is rer~oving the words "to allow higher levels of power production by the alternator" as daere are a number of reasons a high idle switch is required.

These studies have been conducted by n u m e r o u s agencies including the states of California, New York, Idaho, Illinois ,and otilers.

Before the NFPA starts to specify such heavy lighting loads d~ey need to unde r s t and better tile ramifications of requir ing ti~ese min imums. Please note in file articles "Warning on Warn ing

Ligltts" Emergency, March, 1994 and "Roadside Accidents and Warn ing Lights", Law and Order, July, 1991, the State Patrol of C, alifornia mad Illinois found that patrol cars with fewer lights were involved in fewer roadside accidents tiama cars widl mult iple lights systems.

Witil an addit ional light system at the rear down low which will be very distracting to cars approaching f rom that direction. This article could very well be causing mucb more danger to apparatus fire fighters.


Add a new sentence at tile end of %8.6 to read: "The system shall be pernfit ted to have a me thod of modifying the

two signaling modes." Add an appendix to read: "A-9-8.6 Under typical conditions, tile specified optical warning

system provides effective, balanced warning. In some situations, however, the safety of the apparatus may be increased by tu rn ing off some warning devices. For example, if otiler vehicles mus t pass within close proximity to the parked apparatus, tlle possibility of distracting other drivers may be reduced if the headlights and lower level warning lights are tu rned off. When responding in snow or fog, it could be desirable to turn off forward facing strobes or oscillating lights to reduce visual disorientat ion of the apparatus- driver.

The intent of the warning light system is to provide full coverage signals when ei ther responding or blocking tile r ight of way by the operat ion of a single master switch. There is no intent to prevent the use of lower levels of warning when the apparatus driver believes such reduct ions are appropriate, given the vehicle's mission, tile weatiler, or o ther operational factors.

"Additional midship optical warning devices shall be required where necessary to maintain horizontal distance between the centers of adjacent lower level optical warning devices of 18~i't (5.5 m) or less." SUBSTANTIATION: With a 15 ft m a x i m u m distance, many apparatus confignrat ions will require mult iple addit ional midship optical warning devices simply because acceptable m o u n t i n g locations are not available. Chang ing tile m a x i m u m distance to 18 ft (5.5 m) will allow reasonable locational flexibility while main ta in ing the original in tent of the s tandard.

rigilt mad left sides of tile appara tus with the optical center of tile device at a distance of 18 in. to 62 in. (1575 ram) above grade." SUBSTANTIATION: The proposed 48 in. m a x i m u m he igh t will significantly restrict tile installation of emergency lighting on tile apparatus chassis arid body. A 62 in. m a x i m u m he igh t will provide the flexibility requi red to install lower level side emergency lighting on m o d e m fire apparatus witllout compromis ing conspicuity.

"The work area immediately beh ind tile vehicle shall "be i l luminated to a level of 5 foot-candles Within 10 x 10 ft square to tile rear step of the vehicle, f f a hose bed is provided, l ighting on this hose bed shall be at a level of 2 foot-candle or higher. Crosslays (lateral hose beds) tlmt are pe rmanen t ly coveredshal l no t be required to be i l luminated. ' SUBSTANTIATION: This paragraph deals with two different l ighting situations, tile hose bed and tile work area beh ind the vehicle. It also calls for a design of two 30 watt lamps at min imum. Newer technology may allow this funct ion to be accompl ished with little additional cur ren t draw, or a draw of less than tile specified 30 watts. A separat ion of the two areas required to be i l luminated with m i n i m u m light levels should be stated, no t a m i n i m u m power consumpt ion .

I COMMITTEE ACTION: Accept in Principle.

"l-)ocumentation that the entire low voltage electrical system and warning devices have been tested by an i ndependen t testing organization." SUBSTANTIATION: Tills section on low voltage equ ipmen t is a huge Map in technology for ALL fire depar tments . I t will be extremely difficult for fire depa r tmen t personnel to verify compliance. Even most small manufac ture rs will find it difficuh to verify that all parts of the system are in compliance. A third party will protect the buyer and the manufacturer . COMMITTEE ACTION: Accept, in Principle.

Add all appendix to 9-14.1-to read as follows: A-9-14.1 The purchaser may desire to have the entire low voltage

electrical system and warning device system certified by an i ndependen t tes t ingorganizat ion. COMMITTEE STATEMENT: As a m i n i m u m standard, the Commit tee does not wish to make third party testing mandatory for low voltage electrical systems. However, add ing wording in die appendix will alert purchasers to die potential of having their low voltage system tested by an i n d e p e n d e n t t e sdng organization so they can specify it if flley desire.

(Log #138) 1901- 104- (10-1.6): Reject SUBMITTER: Joel Domangue , HME, Inc~ COMMENT ON PROPOSAL NO: 1901-172 RECOMMENDATION: Change the word "Dynamic" to "Static" in the second sentence. SUBSTANTIATION: A dynamic decelerat ion force test is no t feasible or practical for c o m p o n e n t manufacturers , such as radio and siren head manufacturers , e tc . . . , to perform, however a "STATIC": force can be easily calculated and tested by any manufacturer .

Example: I f a radio a n d / o r siren head weighs one p o u n d (1 Ib) a static force test requires dlat the bracket a n d h a r d w a r e used to m o u n t tile radio head mus t be able to withstand a force ten t imes its weight pulled in any direction. Therefore, the brackets mus t sustain a ten (10) p o u n d pull test in any direction; left to right, f ront to back, or up and down.

FAMA agrees with tile objective in keeping equ ipmen t f rom becoming projectiles in tile event of a crash or accident, however a "dynamic" force test is economically and practically impossible, whereas the "Static ' force decelerat ion test is obtainable and pCrovides the same end resulL

OMMITrEE ACTION: Reject. COMM]TI~E STATEMENT: The Commit tee feels that tile SCBA bracket 's holding ability shou ld be dynamically tested so that when the appara tus manufac tu re r installs the brackets according to tile bracket manufac tu re r ' s instructions, there is assurance tha t the bracket will contain the SCBA in tile event of a sudden acceleration or decelerat ion of the fire apparatus.

Static load testing and design calculations shall be required of the apparatus or equ ipmen t manufac tu re r to insure compliance for each coufignrat ion of SCBA hold ing device offered or supplied." SUBSTANTIATION: The r equ i r emen t for SCBA device brackets and the structure to which they are m o u n t e d to withstand a 10 G dynamic decelerat ion test is no t speofic as to applied direction and will be difficult to verily compliance from all apparatus

"manufacturers and e q u i p m e n t suppliers. The proposed wording would conform to Olrrent heavy vehicle design for cab structure and mount ing . COMMITTEE ACTION: Reject. COMMITTEE STATEMENT: The Commit tee feels that the SCBA bracket 's holding ability shou ld be dynamically tested so that when the apparatus maruffacturer installs the brackets according to the bracket manufac tu re r ' s instructions, daere is assurance that the bracket will contain the SCBA in the event of a sudden acceleration' or decelerat ion of the fire apparatus.

SUBSTANTIATION: 1. The proposed text is similar to existing s tandards publ ished by KKK per ta ining to crew and pat ient protection.

2. The r equ i r emen t for FMVSS #206 door locks and door re tent ion componen t s is excessive and unnecessary. No other vehicle s tandard nor FAA safety s tandard goes to tiffs level.

Please revise wording to rcad: ". . . 10 G static force." SUBSTANTIATION: The original wording of tiffs paragraph is stated in such a manner , tha t any testing for this would prove to be very costly. Dynamic test ing usually requires a sled test (possibly every t ime a new feature surfaces). Most companies would no t have the equ ipmen t to per form this procedure . Dynamic decelerat ion testing is a lmost always a destructive test. Whereas, a STATIC test, similar to seatbelt testing done for FMVSS, is no t usually destructive and should still prove to be an acceptable test. A static 10G test is a pull test of ten t imes the weight of the item being tests. This should prove to be an acceptable alternative. COMMITrEEACTION: Accept in Principle.

" SUBSTANTIATION: It is no t practical for all i tems to be enclosed. Many small items; l ikepens , maps, compute r mouse , clipboards; are items dlat mus t be usedwhi le the vehicle is on a run. Other items; like turn-out gear, gloves, face masks, small flashlights, etc.; n eed to be accessible to fire fighters so dley can be ready when they arrive on the scene. .The FMVSS 206 latch has a 2500 p o u n d longitudinal load specification and reqnires considerable space and weight to funct ion properly.

12-9.9.5.3 Water discharge location shall be away from p u m p operators position.

12-9.9.5.4 Shutoff valves OF other means to disable the operat ion of the relief system shall not he permitted. SUBSTANTIATION: The safety critical r equ i rement for an intake pressure relief system, added to the 1991 edition, has been el iminated fi-om die proposed 1996 edition of the stancklrd. Reasons for the r equ i rement were, and still are:

1. To minimize the dangers of water h a m m e r occurring on the supply side of the pump (i.e. protect the supply hose, pump, and personnel) .

2. To protect the pump, supply hose, and personnel from high pressure build-ups in relay p u m p i n g situations. IMPORTANT: NFPA 1901 cannot ,assume that pumper s ups t ream of the uni t built to the 1996 standard, in a relay p u m p i n g set-up, are built to eidler the 1991 or 1996 editions of the standard. As presentlywrit ten, paragraph 12-9.9 Pressure Control System would not necessarily be capable of protect ing the pump, intake hose, and personnel f rom high pressure build-ups in relay operations. The only requ i rement is for control of discharge pressure.

The inG'~ke relief valve should be of d~e direct act ing type because it will seal reliably unde r p u m p pr iming and drafting conditions, while some pilot operated relief valves will actually open dur ing printing operations, prevent ing use of die p u m p for draft ing operations without first isolating the intake relief valve system by means of a wdve or by capping the discharge.

Revise text with: 'Gauges shall be liquid filled or vibration

~ amuB~ened-" TANTIATION: Text reads "Gauges shall be liquid filled and

vibration dampened ." This is a conflict of terms because pressure gauges are liquid filled primarily as a vibration and pulsauon clani-pener. Lqquid fill should not be required if a n t t h e r m e t h o d of vibration d a m p e n i n g is used.

Unfil led or "dry" gauges mee t or exceed all specifications of liquid filled gauges. They are lighter, cost effective, and el iminate the int roduct ion of silicone o]1 to the product. The fire service industry should no t be forced to use one style of product if o ther viable options exist. Dry gauges have been in tile field for many years ~md can out-last and out-perform liquid filled gauges.

Liquid fill does no t enhance a pressure ga- ug-e's performance. For example, NASA has given fltil approval to only drygauges; these withstand extensive vibration, acceleration, etc. to 8.3 g's.

Access gates shall be constructed so that entry to and exit f rom the platform can be made without interference by the gate both from the apparatus side when "bedded" and the "building" side when operating." SUBSTANTIATION: Some existing, late model aerial platforms have separate gates and rails which swing f rom opposite sides.

COMMENT ON PROPOSAL NO: 1901-172 RECOMMENDATION: Change "uncharged" to "charged". SUBSTANTIATION: Allowihg the rated capacity to be stated with the waterway u n c h a r g e d gives a false sense of the capability of the aeri;d platform to the purchaser . As an example, a 100 ft platform with a 5 in. waterway f rom the base to the tip will carry, in a static position, over 850 lb of water within the piping. How does this compute with a platform having a capacity of 750 Ib without water in the piping? What happens to the alleged safety factors when the waterway is charged and the s tream is turne.d off leaving dais excessive weight ,already on the boom? T he fire fighters will unknowingly add addition:d personnel , or civiliaris to the b;tsket in the mistaken belief that they can safely add up to 750 lb to the [c) latform.

"The rated capacity of the elevating platform shall be a m i n i m u m of 750 Ib (340 kg), with no water in the water delivery system, in any position of operation. The rated capacity of the elevating platform shall be a m i n i m u m of 500 lb (227 kg), with the water delivery system fifll of water but not .discharging, in any position of

commit tee is establishing a 500 lb platform load wifll the water delivery system charged, whe the r water is flowing or not, and 750 ]b with no water in the water delivery system. Fire fighters need to unders tand the limits of the mach ine they are using. Ratings will always be h igher for a mach ine with no water in fl~e water delivery system and moving the rat ing to 750 lb with water in the water delivery system will only raise the rating of the mach ine with the waterway uncharged.

SUBSTANTIATION: Vertical he ights over 115 ft can be beneficial to fire depar tmen t s for rescue and fire fighting.

To remove such defect, it involves the usage of mode rn computa t ion wItich is no t foolproof and cost effective by itself wiflmut strict disciplines to br ing designers,

analysis, and even users to unde r s t and how buckling ~s all about and bow it can be avoided. In daat sens* it should be a task force ass ignment for a knowledgeable person to write down no t only generic r equ i r emen t but also all workable essential informat ion for designers to unders tmld and to follow entire model ing procedural of compute r aided nature while engineers will rem:dn in full control, knowing what one is doing. This is d ie only way to access highly reliable m o d e r n computa t ions at very affordable cos t The price for materializing such d ream is to write a new appendix of high-rise aerial ladder design to br ing aerial ladder engineers good a tgnodern computa t ions fl~at are customized to their needs. Wifllout such an effort, to force aerial ladder engineers to do what alley are not capable to, die perils are real and cost is enormous . Mainly, a generalized tool i s no t des igned for everybody, particularly when it involves witb challenges in dynamics, buckling, and numerical traps in computat ional mechanics MI at the same time. National st :mdards mus t promote to gain reliable design at bargain price, no t the reverse. SUBSTANTIATION: There is a fatal loophole for tile equ ipmen t to assure the safety in operation. First of all, let me recap what die most impor tan t rules governing tile design requi rements stated in your proposal. The structural s,-ffety for die aerial ladder crucially depends on the following two requi rements per NFPA 1901 A-16-20.1:

(a) 2xRL + 2xDL < or = FY (b) 2xRL + 2xDL + WL < or = FY where RL = platform live load (or rated capacity) induced stresses. DL = StlUCtUral dead load induced stresses. WL = water j e t nozzle reaction force induced stresses. .FY = yielding stress for structural member s ofd~e boom. My commen t s to dais r equ i r emen t of safety are as follows: 1. The rules set forth in Sections 16-20, A-16-20.1 plus the

certification tests based on Section 16-24 provide no connect ion to protect the ladder against repetit ion of New York City's aerial ladder tragedy. In od~er words, die catastrophic buckling faihlre similar to what h a p p e n e d in NewYork City c~m repeat. Furdlermore , anyth ing that can cause larger vibration ampl i tude mid change signs of handrail stresses will all close to die buckling n igh tmare at d ie mercy of C, od no t to trigger the same "mouse trap effect" of buckling fallnre tbat k i l l edone and in jnred 4 in New York widlout warningI

2. The failure scenario was relativelysimple in dleory. Tha t is: tile only necessary condi t ion to recreate a similar catastrophic buckling failure is to feed into die ladder structural m e m b e r s widl sufficient a m o u n t of kinetic energy in one o f a variety of forms, such as: A 200 pounde r rough landing onto die rescue jDlafform; a sudden s t rong wind sweep across file boom; a water jet-tlow r u n n i n g at peak rate and sitars off quickly; or even any kind of moderate-cyclic-force excitation at a f requency incidentally coincides with one of die lower natural f requencies of die boom. The rules ,xs it is, unintent ional ly designed to br ing die buckling and destruct ion so closely coupled when there is one, it triggers anod le r like a domino. If die safety factor was not des igned so marginal to material 's yielding s t rength (like piano wire), die buckling may not behave so deadly. In dais sense, file rules (a) and (b) by tilemselves are insufficient to p reven t catastrophic failures for the aerial ladders that satisfy bodl all design requi rements and all certification requirements .

Please see news on aerial ladder catastrophe and analytical predict ions made a decade ago relating to somedt ing similar.

"A foam propor t ioning system shall be used that will inject foam concentra te at water flows start ing at (2) two gpm, and shall comply with the applicable requi rements of Chapter 17." SUBSTANTIATION: The low water flow r equ i r emen t is necessary to prevent a slug flow condit ion when: (1) the nozzle is shu t off on an attack line. When a flow is t e rmina ted at the end of a hose line die water flow subsidesgradual ly. If foaming agen t is no t injected at the lower end of water flow then a pocket of air and water only is carried. Anybody that is familiar us ing CAFS on any type of fire will suppor t this concern and s tatement . (2) Any person with an operational background of CAFS on die f i reground (urban interface ,and wildland) knows that a lot of fire can be ext inguished using water flows of ( l ) one or (2) two gpm. This is accomplished with lots of air and a low foam solution flow.

This is an effective ext inguishing m e d i u m (high humidi ty air) working the flarlks of a "grass" fire. (Leaf blowers are used back EastI) Out West this is a c o m m o n practiceI Makes water go a long ways - tests have shown that one mile of line can be constructed with 50 gal of water.
