Committee Scope: This Committee shall have primary ~esponsibility for documents related to the design, inspection. testing, and use of rescue tools for the fire services.

This list repr~we'nts the membership at the tim~. the Committee was balloted on the text of this edition. Since that time, changes in the membership may have occurred. A k~ to classifications is ]ound at the front of this book°

The ReAaort of die Technical Committee on Fire Department Rescue Tools is presented for adoption.

This Report was prepared by die Technical Committee on Fire Department Rescue Tools, and proposes for adoption a new document NFPA 1936, Standard on Hydraulic Powered Rescue Tools°

]'his Report has been submitted to better ballot of the Technical Committee on Fire Department Rescue Tools, which consists of 20 voting members: of whom 14 voted affirmatively, 1 negatively after circulation of negative ballots (Mr. Otte), and 5 ballots were not returned (Messrs. Bazemore, Cibulka, Dempsey, Gage, and Van BastenL

Mr. Otte voted negatively stating: "Proposed standard does not allow testing and compliance of

electromechanical (non-hydraulic) rescue tools, such as die Power Hawk® Rescue Tool. This may result in restriction of trade/business for similar application tools dlat are not hydraulically powered."

(Log #2) 1936- 1 - (3-1.3): Reject SUBMITTER: Ronald G. Cibulka, Underwri ters Laborator ies RECOMMENDATION: T h e p roduc t label shou ld also conta in the tool load rating. S U B S T A N T I A T I O N : The load rat ing is being placed in the manna l ins tead of on the tool namepla te . We feel that the load rat ing should also be on the tool in order to always have this reformat ion available to the nser. The manua l may no t be kept with the tool or it may be lost, damaged , etc., mak ing this informat ion unavailable to the user~ COMMITTEE ACTION: Reject. COMMITTEE STATEMENT: There are mult iple load ratings and rat ing points for each tool and for different points of operat ion.

Nowhere in the s tandard is the re a single load rating specified. This genera l in format ion is better provided in user informat ion as specified in Section 3-2.

(Log #18) 1956- 18 - (4-1.5.12): Accept in Principle SUBMITTER: Alan J. Painter, AMKUS, I n c RECOMMENDATION: Revise as follows:

"The open ing of the spreader of file combination tool shall be opened to the fullest extent using the full hydraulic power and no external load and the opening shall be measured in a straight line on the outside surface of the arms at a point 13 mm (1/2 in.) reward from rite fur thermost projection of file tips. The spreader of the combinat ion tool shall then be closed to its full closure using the hydraulic power and no external load. The opening and closing travel distance of the spreader of the combinat ion tool shall be recorded and verified with the data supplied by the manufacturer. The opening and closing times of the unloaded tool at 21°C, + $°C (70°F, +5°F) shall be recorded." SUBSTANTIATION: This paragraph requires that the travel distance be measured 1 /2 in. f rom the end of the tip. For spreaders we require that the distance be measured at the tip. At one t ime we discussed requiring that this be measured at the same point where the force will be measured. At any rate, I believe that they should be measured at the same location.

Also, I believe that the word reward should have been "rearward." COMMITTEE ACTION: Accept in Principle° See revised text in 4-1.3.15 in the Report on Proposals draft shown at the end of this report. COMMITrEE STATEMENT: The Technical Commit tee felt that the measurement of travel time should be d e p e n d e n t on fully opened distance without potentially confusing o ther positions on the arms or tips.

(Log #21 ) 1936- 24- (4-1.4.10 and 4-1.4.12): Accept in Principle SUBMITTER: Alan J. Painter, AMKUS, Inc. RECOMMENDATION: Revise text to read as follows:

"The opening of the cutter shall be measured in a straight line at the tip of the cutter in the full open position, The opening and closing travel distance of the cutter shall be recorded and verified with the data supplied by the manufacturer." SUBSTANTIATION: We found out what a problem it can be to measure the travel distance at the tips of the cntter some time ago when (name deleted) asked each manufacturer to supply the travel distance ,and the time to close so that he could calculate file speed at which the tool moved in inches per second. Some manufacturers repor ted the distance between the tips when fully opened, others measured file total travel distance, since the tips travel beyond the point where they overlap. This caused some tools to appear to be traveling twice as fast as others when the distance between the tips of the blades when fully open was divided by the time it took to travel the entire distance from fil l open to frill closed. Since the distance traveled beyond the point where the blade tips overlap is absolutely useless, it may make sense to only measure tile distance between the tips of tile blades when fully opened because that is the opening of the blades and represents file largest width that could possibly fit into the blade. COMMITTEE ACTION: Accept in Principle. See revised text in 4-1.4.10 of the Report on Proposals draft shown at the end of dais report.

Paragraph 4-1.4.12 is deleted. COMMITTEE STATEMENT: Tile Technical Committee revised the text to be compatible with file same requirement for tile other tools.

] RECOMMENDATION: Delte 4-2.4. S U B S T A N T I A T I O N : SAEJ343b, in and of itself, does no t require anything. It is a set o f instruct ions for test ing to the requ i rements of SAEJSI7. As discussed at our last meet ing, if we specify that the hose h ~ to conform to the r equ i rements of SAEJSI 7, several adverse condi t ions will exist becanse if a hose does not fall ~nto one of the categories which are specified in SAEJ517, the system cannot be certified as mee t ing our NFPA Standard. Some of t hem are ,is follows:

1. This would limit technology, since it usually takes several years of industry use before SAE even considers creat ing a category and r equ i r emen t s for a new type of hose construct ion.

2. Mamffacturers f rom other countr ies could no t ge t systems certified unless there was an SAE category for the particular bose that they are using, and it has been tested for conformance to SAE J517. It would no t mat ter that d~e difference between operat ing and m i n i m u m burs t pressure me t or exceeded our requirements : as long as there was no category for that part icular hose const ruct ion it could no t be used even it it does mee t internat ional s tandards .

3. The re is presently no category u n d e r SAEJ517 which includes a hose with a m i n i m u m burst pressure of 40,000 psi or greater, which would be requi red u n d e r our s t andard for systems opera t ing at 10,000 psi. Approximate ly half o f the p resen t manufac tn re r s are opera t ing systems at 10,000 psi or higher . We have at least 15 years of exper ience with successfully us ing hydraulic hose with a 200 pe rcen t difference between opera t ing pressure a n d m i n i m u m burst pressure without failure. T he re is no valid reason for onr s tandard to require a h igher difference allan that which is present ly working.

As we discussed at several of onr meet ings , it is recognized that the single greatest reason why hoses fail is due to damage . Increasing the difference between opera t ing pressure and burst

ressure does no th i ng to gua ran tee a safer hose in use in the field. ose fatigue "affecting impulse cycle life at any given pressnre can

be predic ted fairly accurately by m e a s u r i n g the m i n i m u m burst pressure u n d e r control led condit ions. SAEJ1927 "Cumulative Damage Analysis for Hydraulic Hose Assemblies" provides a m e t h o d for predic t ing fatigue life. Section 2 of this d o c n m e n t says, in par t "SAE J343 establishes s tandard test p rocedures - which may be utilized to develop data at pressures o ther than the established ~es~ vah~e for any hose ,assembly", and "It shou ld no t be necessary ¢o use a hose tha t has over a mill ion cycle capability at a pressure that is likely to occur only a few t imes in the application. What is ~aeeded, then, is a des ign verification p rocedure tha t assures ;~dequate fatigue life for appl icat ions with variable ampl i tude pressure usage where the majority of the peaks are between 100 and 200 pe rcen t of rated pressure." The strict in terpreta t ion of the di f ference between burst and operat ion pressures of 400 percent is u m ~ safety related issue. Rather, it is a cycle life issue. Having dif ference between opera t ing and burst pressures o f 400 percent provides a predic ted cycle life of approximate ly 5 million impulse cycles at 100 pe rcen t of the rated opera t ing pressure when the pressure ampl i tude is constant , which is certainly overkill in our application. Reducing this d i f ference to 200 percen t does reduce the predicted impulse cycle life considerably. However, this is a llfe issue, no t a safety issue.

He is willing to be p resen t and participate in a discussion abu t hydrattlic hose a t our nex t commi t tee meet ing.

equipment , or materials; nor does it approve or evaluate testing laboratories. In de te rmin ing the acceptability of installations, jPurOCedures, equipment , or materials, the authority llaving

risdiction may base acceptance on compliance with NFPA or o ther appropria te standards. In the absence of such standards, said authority may require evidence of proper installation, procedure, or use. The authority havingjurlsdict ion may also refer to tile listings or labeling practices of an organization that is concerned with product evaluations and is thus in a position to de te rmine compliance with appropria te standards for the current prodoct ion of listed items.

A-I-3 Authority Having Jurisdiction. Tile phrase "authority having jnrisdict ion" is used in NFPA documents in a broad manner , since jurisdictions and approval agencies vary, as do their responsibilities. Where public safety is primary, the authority i lavingjurisdicdon may be a federal, state, local, or o ther regional depar tment or individual such as a fire chief; fire marshal; chief of a fire prevention bureau, labor depar tment , or bealth depar tment ; building official; electrical inspector; or others having statutory authority. For insurance purposes, an insurance inspection

safety certification program would be deficient without these contractual provisions and the administrative means to back them up.

A-~-'/.4 Investigative procedures are impor tant elements of an effective and meaningful product safety certification program. A preliminary review should be carried out on products submitted to tile agency before any major testing is undertaken.

A-2-9.7 Such inspections should include, in most instances, witnessing of product ion tests. In the case of certain products, the certification organization inspectors should select samples from the product ion ilne and should submit them to the main laboratory for countercl~eck testing. In the case of other productS, it can be desirable to purchase samples in the open market for test purposes.

Any hydraulic rescue tool system or hydraulic rescue ~oo~ that does not bear the mark of an independent , third-party certification organization is NOT COMPLIANT with NFPA 1936, even if the product label states that the ~ten~ is compl iant !

For fur tber information about certification and product labeling, Chapters 2 and 3 of NFPA 1936 should be referenced. Also, the definitions for certification/certified, labeled, and listed in Section 1-$ should be reviewed.

Third-pa~y certification is an impor tant means of ensuring the quality of hydraulic rescue tool systems or hydraulic rescue tools. To be certain that an item is properly certified, labeled, and listed, NFPA recommends that prospective purchasers require appropriate evidence of certification for the specific product arid model from the manufacturer before purchasing. Prospective purchasers should also contact the certification organizations and request copies of the certification organization's list of certified products to tile appropriate NFPA standard. This listing is a requi rement of third-party certification by dais s tandard and is a service performed by the certification organization. A-2-2.1 The certification organization should have a sufficient breadth of interest and activity so that the loss or award of a specific business contract would not be a de te rmin ing factor in tile financial well-being of the agency.

A-2-2.3 The contractual provisions covering certification programs should contain clauses advising the manufacturer that, if requirements change, the product should be brought into compliance with the new requirements by a stated effective date through a compliance review program involving all currently listed products.

Without these clauses, certifiers would not be able to move quickly to protec t their names, marks, or reputations. A product
