25 mm (1.024 in.) +5%, in diameter which is equivalent to 0.1 degree angular aperture;

(e) The exit aperture of the source shall be circular and 26 mm (1.024 in.), +_5%, in diameter which corresponds to 0.1 degree angular aperture;

( f ) Retroreflector reference angle = 90 degrees, and (g) Datum mark shall be placed as specified by the trim

manufacturer. 9-x.4.1.2 The Coefficient of Retroreflection (Ra) shall be

calculated by the following equation: R a = R1/A f

where: R 1 is the coefficient of luminous intensity measured as specified

in 9-x.4.1.1; and Af represents only the retroreflective surface are of the trim test

specimen's surface area. Af shall be calculated by subtracting the non-retroreflective surface area from the test specimen's total surface area.

9-x.4.2 Evaluation of Fluorescence. 9-x.4.2 Trim fluorescence shall be determined by examining the

material under a black light at a distance of 30.5 cm (12 in.) for a period of 30 seconds.

SUBSTANTIATION: The current requirement for glove dexterity is a report-only requirement. Dexterity is a serious problem among users of vapor-protective suits and a minimum requirement should be provided that ensures end users have an appropriate level of dexterity for performance of tasks during emergency chemical response. COMMITTEE ACTION: Accept.


1991- 4 - (3-2.5 (New)): Accept in Principle SUBMITTER: Jeffrey O. Stull, Int'l Personnel Protection, Inc. RECOMMENDATION: Add new paragraph to read as follows:

3-2.5 The manufacturer shall provide the recommended storage llfe for each vapor-protective suit.

Storage Life. The date that the vapor-protective suit should be taken out of service when the vapor-protective suit has not been used in either training or for actual use and has undergone proper care and maintenance in accordance with manufacturer's instructions.

Care. Procedures for cleaning, decontamination and storage of vapor-protective suits.

Maintenance. Procedures for inspection, repair and removal from service of vapor-protective suits. SUBSTANTIATION: These products are typically stored for long period without use. End users should be made aware of the storage life limitations that exist for vapor-protective suits. Only manufacturers are in a position to provide this information. COMMITTEE ACTION: Accept in Principle.

Add new definition "Storage Life" to read as follows: Storage Life. The date to remove from services a vapor-protective

~nsemble, or separable elements of the ensemble, that has undergone proper care and maintenance in accordance with the manufacturer's instructions but has not been used either in training or for actual use.

Accept "care" and "maintenance" as submitted. COMMITTEE STATEMENT: Committee modified definition of "storage life" to be concise and not to include requirements.


1991- 5 - (4-1.x (New), 9-x (New)): Accept in Principle SUBMITTER: Jeffrey O. Stull, Int'l Personnel Protection, Inc. RECOMMENDATION: 1. Add new requirement for overall ensemble as follows:

5-1.5 Vapor-protective ensemble spedmens shall be tested for inward leakage as specified in Section 6-x, Overall Ensemble Inward Leakage Test, and shall have no inward leakage greater than 0.05 percent.

2. Add new test method, Section 6-x as follows: 6-x Overall Ensemble Inward Leakage Test. 6-x.1 Application. 6-x.l.1 This test method shall apply to complete vapor-protective

ensembles. 6-x.2 Specimens. 6-x.2.1 A minimum of one specimen shall be tested. 6-x.3 Sample Preparation. 6-x.3.1 Samples for conditioning shall be complete vapor-

protective ensemble. 6-x.3.2 Specimens shall be conditioned as specified in 6-1.2. 6-x.4 Apparatus. fi-x.4.1 High purity sulfur hexafluoride shall be used as the test

agent. 6-x.4.2 A test chamber shall be used for conducting this test.

The test chamber shall have minimum dimensions of 1.5 m wide by 1.5 m long by 2.4 m high (5 ft x 5,ft x 8 ft). The test chamber shall be made from a transparent material. The test agent shall enter the test chamber at the top of the chamber through a flow distributor and shall be directed downward over the head of the test subject at a flow rate of 0.12 m/s (3.28 ft/s) as measured in the region next to the subject's head.

6-x.4.3 A sample probe for measuring the concentration of the test agent in the test chamber shall be positioned in the region next to the test subject's head. The sample probe shall be

993

N F P A 1991 m F 9 9 R O P

configured in such a manner as to allow sampling of the test agent concentration within the test chamber at intervals of 1 minute.

6-x.4.4 A portable pump and adsorbent system capable of collecting sulfur hexafluoride shall be worn inside the specimen in the breathing zone area of the test subject. The sampling pump shall operate at a flow of 200 mL/min. The adsorbent shall have a minimum adsorption capadty of 0.1 mg of sulfur hexafluoride.

6-x.4.5 Test subjects shall be familiar with the use ofvapor- rOtective ensembles and with self-contained breathin~ apparatus CBA). Test subjects shall have had a medical examination

within the past year which shows the test subject to be in good health. The test subject shall select the appropriate size of the vapor-protective suit from available sizes using the manufacturer sizing chart.

6-x.4.6 A Scott 4.5 Air Pak shall be used in all testing as the self- contained breathing apparatus for use with the vapor-protective ensemble.

6-x.5 Procedure. 6-x.5.1 Sulfur hexafluoride shall be supplied to the test chamber

such that the concentration of sulfur hexafluoride is at 1000 parts

~ er million, +100 parts per million over the test period duration. he concentration of sulfur hexafluoride inside the test chamber

shall be monitored for the length of test until the test subject exits the test chamber at intervals o f at least 1 minute.

6-x.5.2 The test subject shall be outfitted with a portable sampling pump which is attached to test subject's collar with the sample port near the wearer's breathin~.g zone. The pump shall be activated before closing the suit. The ume that the pump is activated shall be recorded to the nearest second.

6-x.5.3 The test subject shall don the self-contained breathing apparatus and vapor-protective ensemble in accordance with manufacturer instructions.

6-x.5.4 The test subject shall then enter the test chamber. The time that the test subject enters the test chamber shall be recorded to the nearest second.

6-x.5.5 The test subject shall remain in a standing position for 3 minutes, +15/-0 seconds, and shall then perform three series of the stationary exercises specified in Procedure A in ASTM Fl154, Standard Practices for Qualitatively Evaluating the Comfort, Fit, Function, and Integrity of Chemical-Protective Suit Ensembles.

6-x.5.6 At the conclusion of the exercises, the test subject shall remain in a standing position for 3 minutes, +15/-0 seconds, and then exit the chamber. The time that the test subject exits the test chamber shall be recorded to the nearest second.

6-x.5.7 In an area well away from the test chamber, the test subject shall doff the vapor-protective ensemble and shall turn off the sampling pump. The time that the test subject turns off the sampling pump shall be recorded to the nearest second.

6-x.5.8 The amount of the sulfur hexafluoride adsorbed by the sample pump absorbent shall be determined using a suitable analytical technique which is capable of measuring sulfur hexafluoride at the required detection level.

6-x.5.9 Testing shall be discontinued prematurely for any of the following reasons:

(a) The concentration of sulfur hexafinoride in the test chamber exceeds 1100 parts per million for more than one minute.

(b) The test operation observes an unsafe condition or notices fatigue on the part of the test subject.

(c) The test subject complains about dizziness, unsteadiness, fatigue, or any condition.

(d) The test subject asks to terminate the test. 6-x.6 Report. 6-x.6.1 The concentration of the sulfur hexafluoride in the test

chamber at each measurement interval shall be reported° The average concentration of the sulfur hexafluoride in the test chamber from the time the test subject enters the test chamber to the time the test subject exits the test chamber shall be determined and reported.

6-x.6.2 The concentration ofsuffur hexafluoride within the vapor-protective ensemble shall be determined using the amount of sulfur hexafluoride found in the adsorbent, the pump flow rate, and the time the test subject was in the test chamber. The concentration of sulfur hexafluoride inside the vapor protective ensemble shall be reported in lag/L.

6-x.6.3 The percent inward leakage shall be determined by dividing the measured concentration of sulfur hexafluoride inside the vapor-protective ensemble by the average concentration of sulfur hexafluoride in the test chamber during the time the test subject was in the test chamber and multiplying by 100. The percent inward leakage shall be reported to the nearest tenth of a percent,

6-x.7 Interpretation.

6-x.7.1 The calculated percent inward leakage shall be used to determine pass/fail performance. SUBSTANTIATION: The pressure test sl3edfied in 4-1.2 is primarily a quality control technique apphed to each suit. This technique, while capable of detecting small leaks, is done statically (without simulation of use) and does not evaluate the integrity of the full ensemble since the exhaust valves must be dosed for the pressure test. The proposed test provides a complete, manned evaluation of the ensemble in a manner representative of actual use. The test is based on a procedure used in Europe for gas-tight suits (EN 943), Part 1. COMMITYEE ACTION: Accept in Principle.

See 5-1.5 and 6-8 of the F99 Report on Proposals draft shown at the end of this report for the requirements. COMMITTEE STATEMENT:

The Committee changed the pass/fail inward leakage to 0.02 percent to provide a more severe challenge for the surrogate chemical test.


1991- 6 - (4-1.4, 7-1.2.1 (New), 9-2): Accept SUBMITTER: Jeffrey O. Stull, Int'l Personnel Protection, Inc. RECOMMENDATION: 1. Modify and renumber paragraph 4-1.4 and Section 9-2 as follows:

6-4.5.4 The visual acuity of the test subject in and out of the suit shall be reported.

6-4.5.5 The ability of the test subject to repeatedly remove and reinsert his or her hands completely into the gloves shall be reported.

6-4.5 Interpretation. 6-4.5.1 Following the test subject exercises, an ending suit

pressure of less than 80 mm (3.2 in. water column gauge) shall constitute failing performance.

6-4.5.2 The inability of the test subject to satisfactorily complete all exercises shall constitute failing performance.

6-4.5.3 The non-accommodation of head protection meeting the dimensional requirements of ANSI Z87.1, Top Impact, Class B Cap, by the vapor-protective suit shall constitute failing performance.

6-4.5.4 The visual acuity of the test subject inside the suit shall be used for determining pass/fall.

6-4.5.5 The inability of the test subject to repeatedly remove and reinsert his or her hands completely into the gloves shall constitute failing performance. SUBSTANTIATION: The proposed requirement consolidates several existing requirements, l~lus allows the evaluation of wear removal and reinsert of hands mto the glove system, a perennial problem with some suit styles. COMMITTEE ACTION: Accept.


1991- 7- (4-1.8): Accept SUBMITrER= Jeffrey O. Stull, Int'l Personnel Protection, Inc. RECOMMENDATION: Add new paragraph to read as follows:

4-1.8 Vapor-protective suits shall be offered in at least four unique and different sizes. SUBSTANTIATION: Currendy there are no sizing requirements for vapor-protective suits. A significant hazard in wearing a v~ap.or- protective suit is improper sizing which decreases wearer mobility, field of vision, and comfort. Minimum sizing will help to provide a range of vapor-protective suit sizes which better accommodates the user population. COMMITTEE ACTION: Accept.

Committee: (~-#2H~2) 1991- 8- (4-2.$): Reject SUBMITTER= Jeffrey O. Stull, Int'l Personnel Protection, Inco RECOMMENDATION: Revise paragraph 4-2.3 as follows:

SUBSTANTIATION: The end user community has indicated that they would like liquid splash-protective suits to possess some level of flame resistance, but the current test is overly severe for preventing the use of materials which easily ignite and continue to burn. Modification of the flame resistance requirement as suggested permits a wide range of materials which would be self- extinguishmg and allow the end user to select a higher level of flame resistance with optional flash fire protection was chose. COMMITTEE ACTION: Roect. COMMITTEE STATEMENT: Proposal reduces the minimum flame resistance level to below the acceptable level.


1991- 9 - (4-5.1, 4-$.2, 4-5.4, 4-5.5, 4-6.4, 4-6.5, 4-7.1, and 4-7.2): Reject SUBMITrER= Jeffrey O. Stull, Int'l Personnel Protection, Inc.

provide performance consistent with all parts of the ensemble, including closures. Sulfur hexafluoride represents a viable test chemical surrogate. COMMITTEE ACTION: Reject. COMMITTEE STATEMENT: The Committee believes differences in material construction that are affected by flexing and abrasion may not be detected by a single surrogate chemical.


1991- 10- (4-3.3): Accept Note: This Proposal appeared as Comment 1991-12 which was

held from the Annual 94TCD on Proposal 1991-2. SUBMITTER= Jeffrey o . Stull, Austin, TX RECOMMENDATION: Change paragraph 4-5.5 to read:

"Garment materials samples shall be tested for bursting strength and shall have a bursting strength of not less than 200 N (45 Ibf) as specified in Section 9-10 of this standard." SUBSTANTIATION: The new minimum requirement reflects a change is the selected test method for measuring bursting strength. The table shows a comparison of the two techniques for selected chemical protective clothing materials.

Note: Supporting material is available for review at NFPA Headquarters. COMMITTEE ACTION: Accept. COMMITTEE STATEMENT: Number revised to new format. See Section 5-2.3 of the 1799 Report on Proposals draft shown at the end of this report.

1991- 12 - (4-5.2): Accept in Principle Note: This Proposal appeared as Comment 1991-15 which was

held from the Annual 94TCD on Proposal 1991-2. SUBMITTER: Jeffrey O. Stull, Austin, TX RECOMMENDATION: Modify paragraph 4-5.2 to:

"Glove material samples shall be tested for cut resistance and shall exhibit a cut distance of 1 in. (2.5 cm) at 0.9 Ib (0.4 kg) or greater when tested as specified in Section 9-15 of this standard." SUBSTANTIATION: The currently specified cut resistance test method fails to adequately discriminate cut resistance performance of chemical protective clothing and suffers from lack of interlaboratory accuracy and precision as demonstrated by the ASTM F25 Committee on Protective Clothing. The proposed test method reflects significant improvements in test preaston and discrimination of performance among chemical protective clothing tests. The proposed performance requirement is "equivalent" the original requirements based on testing for the same products. COMMITTEE ACTION: Accept in Principle. COMMITTEE STATEMENT: See Committee Action and Statement on Proposal 1991-15 (Log #11).

(Log #11 ) Committee: FAE-HAZ

1991- 13 - (4-5.2 and 4-6.2): Accept SUBMITTER: Jeffrey o . Stull, Int'l Personnel Protection, Inc. RECOMMENDATION: Replace glove and footwear cut

I requirements and test method. Modify requirements for glove and footwear as follows: 5-4.3 Glove material specimens shall be tested for cut resistance

as specified in Section 6-11, Cut Resistance Test, and shall have a cut distance of not more than 25 mm (1.0 in.).

5-5.3 Footwear upper material specimens shall be tested for cut resistance as specified in Section 6-11, Cut Resistance Test, and shall have a cut distance of not more than 25 mm (1.0 in.). SUBSTANTIATION: The cut test method in the 1994 edition of the standard is imprecise and does not readily discriminate performance among different gloves. The recommended test method is based on ASTM F1790, which has recently been approved and applies to a full range of glove systems. COMMITTEE ACTION: Accept.

(Log #7a) Committee: FAE-HAZ

1991- 14 - (4-5.7 (New)): Accept in Principle SUBMITTER: Jeffrey O. Stull, lnt'l Personnel Protection, Inc. RECOMMENDATION: Add new paragraph 4-5.7.

4-5.7 Glove specimens shall be tested for dexterity as specified in Section 9-7, "Dexterity Test" and shall have the dexterity time not exceed 140 percent of the bare-handed control time. SUBSTANTIATION: The current requirement for glove dexterity is a report-only requirement. Dexterity is a serious problem among users of vapor-protective suits and a minimum requirement should he provided that ensures end users have an appropriate level of dexterity for performance of tasks during emergency chemical response. COMMITTEE ACTION: Accept in Principle.

Revise text to read: 5-4.6 Glove specimens shall be tested for hand function as

specified in Section 6-17, Glove Hand Function Tests, and shall meet the following requirements:

(a) The glove specimens shall have an average percent of barehand control not exceeding 140 percent for the Gross Dexterity Test A;

(b) The glove specimens shall have an average percent of barehand control not exceeding 140 percent for the Gross Dexterity Test B;

(c) The glove specimens shall permit a pin with an average diameter of 5 mm (0.20 in.) to be picked up for the Fine Dexterity Test;

(d) The glove specimens shall permit pins with an averagte spacing of 5 mm (0.20 in.) to be detected for the TactilityTest; and

(e) The glove specimens shall have an average percent of barehand control average of not less dlan 80 percent for the Grip Test. COMMITTEE STATEMENT: The Committee added more criteria and renumbered.


1991- 15 - (4-5.8 (New)): Accept in Principle SUBMTI'rER: Jeffrey O. Stull, Int'! Personnel Protection, Inc. RECOMMENDATION: Add new paragraph to read as follows:

4-5.8 The design of the glove to vapor-protective suit sleeve interface shall be designed to permit removal o f gloves within 30 seconds and permit tile replacement of gloves. SUBSTANTIATION: End users should have the ability to readily replace gloves wltich have become damaged or need to be resized to fit tile individual wearer. COMMITTEE ACTION: Accept in Principle.

Add new 4-2.2 to read: 4-2.2 The glove to vapor-protective suit sleeve interface shall be

designed to permit removal and replacement of the gloves attached to each suit sleeve witlfin 30 minutes. COMMITTEE STATEMENT: The Committee agrees with the submitter but views glove replacement as a maintenance function and not intended to be a "field" function.

Therefore, the Committee has set a removal/replacement time at 30 minutes.

3. Delete Section 9-25. SUBSTANTIATION: 1994 edition of NFPA 1991 evaluates closures for liquid penetrat ion onl~f, even though the rest of the ensemble" is evaluated for permeauon resistance. This represents an inconsistency in the testing of the ensemble and allows the closure to be the weakest link in the ensemble design. COMMITTEE ACTION: Reject. COMMITTEE STATEMENT: The suit closure system is evaluated through other tests required in this standard such as the shower test, pressure test, and reward leakage test.

6-x.7 Interpretation. 6-x.7.1 The average mounting strength shall be used to

determine pass/fail performance. SUBSTANTIATION: Exhaust valves may. be accidentally pushed in when the ensemble wearer bumps against a solid object such as a wall. The proposed test specifies a minimum strength for the exhaust valve mounting in the suit wall. This requirement is intended to prevent accidental push-in of the suit exhaust valve. COMMITTEE ACTION: Accept.

to the nearest 1 N (1 /4 Ib force). The average pull out s trength shall be calculated and repor ted to the nearest 1 N (1 /4 lb force).

6-x.7 Interpretation. 6-x.7.1 The average pull out s trength shall be used to determine

sPass/fall performance. UBSTANT1ATION: There are no current requirements which

address tile s l rength of the fittings installed on the suit wall. These fittings may be subjected to forces resulting from the wearer pulling air line or having the air line caught on an object. The pull out of the fitting would result in catastrophic loss of suit integrity. The r ecommended test is in tended to establish min imum requirements for the strength of fitting mount ing on the suit wall. COMMITTEE ACTION: Accept.


1991- 20 - (5-2.1): Accept in Principle SUBMITTER: Jeffrey O. Stull, Int'l Personnel Protection, Inc. RECOMMENDATION: Modify performance requi rement in paragraph 5-2.1 and test me thod In Section 9-17:

Revise as follows: 5-2.1 Sample wapor-protective suits shall be tested for overall

ensemble flash protect ion and shall s h o w after f lame times no longer than 2 seconds and in s u b s e q u e n t m a n n e d wearing of the sample ensemble . . . . . . . . . . . . . . ~, v . . . . . . . . . . . . . . . . . . . . . . . . .

testy and all'ow test subject shall have a visual acuity o f 20/100 when tested as specified by Section 9-27. SUBSTANTIATION: The intent of the requirements in Chapter 5 are to demonstra te the protect ion qualifies of the vapor-protective suit in allowing the end user to safely escape after a chemical flash fire has occurred. It is not in tended that the vapor-protected suit continue to provide the same level of performance as originally required. COMMITTEE ACTION: Accept in Principle.

I evise 5-2.1 to read: "Vapor-protective ensemble shall be tested for flash fire protect ion as specified in Section 6-27, Overall Ensemble Flash Test, and shall no t have any after flame time of longer than 2 seconds, shall p e r m i t visual activity through the faceshield or visor material o f 20/100 or better, and shall s h o w an ending pressure of at least 13 mm (1/2 in.) water gauge when subsequently tested as specified in Section 6-2, as Tight Integrity Test; COMMITTEE STATEMENT: The Committee feels that there should be an integrity test of "positive pressure" and chose 13 mm water gauge as a minimum indication of retaining positive pressure.


1991- 21 - (5-2.4): Accept SUBMIIq'ER: Jeffrey O. Stull, Int'l Personnel Protection, Inc. RECOMMENDATION: Revise as follows:

5-2.4 Specimens of suit material and glove material shall be tested for rate of stadc electric discharge as specified in Section 6- 29, Static Charge Accumulation Resistance Test, and shall show no voltage greater than 350 volts, 5 seconds after termination of charge generation. SUBSTANTIATION: The current requi rement is impractical for measuring hazards of electrostatic discharge since interior layers will not be subject to the same electrostatic potential as the exterior surface (e.g., the environment inside the suit will be humidified). The proposed revisions to the performance requi rement and test me thod provide a more realistic means for assessing suit performance against this hazard. COMMITTEEACTION: Accept. COMMITTEE STATEMENT: Number revised to new format. See 5-6.4 of the F99 Report on Proposals draft shown at the end of this repor~


1991- 22 - (9-10.1): Accept Note: This Proposal appeared as Comment 1991-32 which was

held from the Annual 9 4 T C D on Proposal 1991-2. SUBMrrTER: Jeffrey O. Stull, Austin, TX RECOMMENDATION: Change paragrapb 9-10.1 to read:

"Material burst s t rength shall be measured in accordance with ASTM D 751, Methods of Testing Coated Fabrics, Bursting Strength, using the tension testing machine with ring clamp." SUBSTANTIATION: Burst s trength tesdng based on the mullen technique does no t properly evaluate nonwoven or highly elastic materials because these materials elongate and provide inaccurate measurements . The ball and ring clamp me thod equally accommodates chemical protective clothing materials and better simulates the physical hazard being modeled. COMMITTEE ACTION: Accept. COMMITrEE STATEMENT: Number revised to new format. See 6-10.1 of the F99 Report on Proposals draft shown at the end of this report.


1991- 23 - (9-15): Accept in Principle Note: This Proposal appeared as Comment 1991-36 which was

held from the Annual 9 4 T C D on Proposal 1991-2. SUBMITTER: Jeffrey O. Stull, Austin, TX RECOMMENDATION: Replace Section %15 witll the following procedure :

9-15 Glove and Footwear Upper Material Cut Resistance Test. 9-15.1 Each sample specimen shall be a 2 in. x 4 in. (5 c m x 10

cm) rectangular specimen. Multiple cut at tempts shall be permit ted to be made on each specimen. Glove samples for cut resistance shall be taken from the palm or back of file glove, whichever area is thinnest. Footwear upper samples for cut resistance shall be taken from the areas of the footwear upper where the thickness is uniform.

%15.2 During the test, the sample specimen shall be oriented so that the normal outer surface of file glove is the first to be contact by the edge of the blade.

9-15.3 Five cuts shall be made on each sample specimen at each load.

%15-4* A cut performance tester shall be used for measuring cut resistance (Figure 9-15.4 shows a photograph of file device labeling its var iousparts and components) .

9-15.5" Textile Gru-Gru blades shall be used with this device. %15.6 Before turning on or operating the cut performance tester,

the test operator shall ensure that there are no blades in the blade holder and there are no weights on the cutting arm.

9-15.7 The ins t rument shall be operated ,as follows: 9-15.7.1 The device shall be plugged in a 110 VAC outlet and

turned on. %15.7.2 The cutting arm shall be calibrated by first installing a

new blade into file blade holder. The counterweights on file rear of the cutting arm shall then be adjusted such that the arm is balanced with the blade just contacting the material mandrel .

9-15.7.3 With tile blade still in the blade holder, the angle of blade contact with the mandrel shall be checked. The blade shall make fiat, parallel contact with the surface of the mandrel .

999

N F P A 1991 - - F99 R O P

Adjustments to correct this contact shall be adjusted with the two Allen bolts on the side of the mandrel. The Allen bolts shall be tightened after any adjustments are made.

0-15.7.4 The blade shall be removed from the blade holder. 9-15.7.5 The test operator shall ensure that the cutting arm is in

the far rear position and make adjustments by turning the small hand crank on the cutting arm cam.

%15.7.6 A 2.0 in x 4.0 in. (5.0 x 10.0 cm) piece of double-sided tape shall be placed on the mandrel for securing the sample onto the cut performance tester.

9-15.7.7 The material specimen shall be placed over the top of the double-side tape on the mandrel. The test operator shall ensure that the material specimen makes smooth contact with all portions of the mandrel. The material specimen shall be cut on ~ts bias (at a 45 degree angle to machine and cross-machine directions).

%15.7.8 The blade shall be inserted into the blade holder with the cutting arm slot and tightened by the thumb screw.

9-15.7.9 With the cutting arm held off the sample with the arm rest, the selected weights shall be placed over the rod on the cutting arm.

9-15.7.10 The distance measuring counter shall be zeroed. 9-15.7.11 The special tool shall be inserted into the hole located

at the end of the cutting arm. Using this tool, the cutting arm shall be lifted, and the arm rest flipped over so that the blade rests on the material specimen gently.

9-15.7.12 The cut performance tester shall be started by selecting forward and pressing the on button.

%15.7.13 The cut performance tester shall stop its motion once the blade has cut through the material specimen and contacted the metal mandrel. When the cut performance tester has stopped, the weight and distance cut shall be recorded.

9-15.8 Tests shall be rerun at a higher weight if the cut performance tester does not cut through the material and stop in one cycle.

9-15.9 A individual blade shall be used only for each replicate cu t .

9-15.10 Additional weights shall be added and the procedure repeated per 9-15.7 to achieve cut distances ranging from approximately 0.3 to 1.8 in (0.7 to 4.5 cm).

9-15.11 The load (weight) versus distance data shall be plotted on a graph. The load value at a cut distance of 1 in (2.5 crn) shall be interpolated by a best fitting curve of the data and reported as the load to "1 in. (2.5 cm) cut."

A-9.15.4 The Cut Performance Tester is available from Ashland, Inc. 2388 Brackenville Road, Hockessin, DE 19707 (302-239-2018).

A-9-15.5 Textile Gru-Gru blades, Part No 88-0121, from the American Safety Razor Blade Co., Staunton, Virginia (1-800- 33674061 ) are suitable for this test. SUBSTANTIATION: The currendy specified cut resistance test method fails to adequately discriminate cut resistance performance of chemical protective clothing and suffers from lack of interlaboratory accuracy and precision as demonstrated by the ASTM F23 Committee on Protective Clothing. The proposed test method reflects significant improvements in test precision and discrimination of performance among chemical protective clothing tests. COMMITTEE ACTION: Accept in Principle. COMMITTEE STATEMENT: See Committee Action and Statement on Proposal 1991-24 (Log #11a).


1991- 24- (9-15): Accept SUBMITTER: Jeffrey O. Stull, Int'l Personnel Protection, Inc. RECOMMENDATION: Replace glove and footwear cut requirements and test method.

in 9-29.2.1. 9-29.4 Apparatus. 9-29.4.1" Triboelectric Test Device. The triboelectric test device

shall consist of a grounded aluminum frame with two cutouts in the front face plate.

(a) The lower right :utout shall house the static detector head that is connected to an electrometer.

(b) The upper left cutout shall be for the rubbing wheel used to generate the triboelectric charge.

(c) This rubbing wheel shall be connected to a 1/8 horsepower electric drive motor. A manual lever shall be used to slide the motor/rubbing wheel combination forward so that the steel gently makes intimate contact with the test specimen at the proper time.

(d) The test pressure shall be held constant during the test by means of weight and cord system. In this system, a cord shall be attached to the motor assembly, shall run over a pulley wheel, and a 1.4 kg _+ 0.05 kg (3 lb + 0.2 Ib) weight shall be attached to the end of the cord.

(e) The test specimen shall be mounted taut in a grounded specimen holder.

9-29.4.2* Rubbing Wheel. The rubbing wheel shall have a diameter of 127 m m + 2 mm (5 in., zk 0.1 in.) The standard wheel shall be constructed with a phenolic plastic (such as Micarta) back, a 25.4 mm (1 in.I thick foam cushion, and a felt PTFE rubbing surface. Rubbing wheels shall be cleaned with a dry cloth after the completion of tests on a given material.

9-29.7 Interpretation. 9-29.7.1 The average measured voltage at five seconds for each

surface tested shall be used individually to determine pass/fall. SUBSTANTIATION: The current requirement is impractical for measuring hazards of electrostatic discharge since interior layers will not be subject to the same electrostatic potential as the exterior surface (e.g., the environment inside the suit will he humidified). The proposed revisions to the performance requirement and test method provide a more realistic means for assessing suit performance against this hazard. COMMITTEE ACTION: Accept.

During all future calibration procedures, the voltage setting o f the quartz lamps shall be compared to the current voltage setting of the new quartz lamps, and if the voltage increase is 5 V or greater from the initial setting, the lamps shall be replaced.

6.28.5.2.4* The two Meker or Fisher burners shall be initially adjusted so that the flames converge upon each other just below the center of the radiometer. The color of the flame shall primarily be blue.

6.28.5.2.5 The radiant thermal flux source of nine quartz infrared tubes alone shall be set to an incoming radiant heat flux of 12 kW/m ~, +4 kW/m ~ (0.3 cal/cmSs, i'0.1 cal/cm2s) usinga commercial radiometer meeting the specifications of 6-28.4.2. The radiometer window shall be positioned at the geometric center of the sample holder and at the same plane as a test specimen. The radiometer.shall be mounted in a holder of the same overall size, shape, and material as the one used for the copper calorimeter to ensure similar heat arhd flamepatterns across the faces of the radiometer and calorimeters. The radiant quartz tubes shall be turned on and "run" for a minimum of 2 minutes prior to measuring the radiant, heat flux.

6-28.5.2.6 The total heat flux shall be set at 83 kW/m ~, +4 kW/m z 2 2 (2.0 cal/cm s, ~0.1 cal/cm s) using the calibration copper

calorimeter, defined in 6-28.4.1.10, by adjusting only the gas supply to the Meker or Fisher burners. Without a mounted specimen, the calibration copper calorimeter shall be placed on top of the specimen holder with the blackened copper calorimeter facing down and then exposed directly to the flame of the burner. The response of the calorimeter shall be recorded for at least 10 seconds. The lowest temperature point on the curve where the response is linear shall be chosen, and the increase in sensor temperature for 10 seconds of heating shall also be determined. The initial reading from the 10-second reading shall be subtracted to obtain the increase. The response shall be 148°C, + $.7°C (267°F, + 6.7°F) equisalent to 7.86, + 0.20 mV for an iron- constantan thermocouple for an exposure heat flux of 83 ~ +2 kW/m ~ (2.0 cal/cm~s, :L-0.05 cal/cm%). ~-~"~ .,,

Appendix A Explanatory Material

Appendix A is not a,~rt of the requirements of this NFPA document but is included for ~ o n a l purposes °nO" This appendix contains explanatory m a ~ nurab~ed to correspond with the applicable text

A-I-I.1 _T.~Kr'e~uireffi¢#,~l~ of this standard were developed taking into c o ~ e r ~ i ~ the ~ f emergency response personnel for hazar.,~'us ..Kaaterials emer~!i"cies. This application can entail a v a r j ~ f c l~gica l , physi4~£1, and other hazards. Other protection n ~ t ~ . ~ - r a n t a thorough review of the requirements in this ~ , s t ch as routine industrial operations to determine heir a p p ~ . l i t ~ ~There a r e ~ u i r e m e n t s in this standard that address reuse or

w e a ~ s ' o f vapor-protective ensembles. Users are : a ~ t exposure of vapor-protective ensembles to i . ~ ] n i c , ~ o u l d require disposal, particularly if the effectiveness of Fecont,'~l~hination cannot be assessed. '.~g.t the time this standard was prepared, the characteristics of a

%r particulate flash fire have not been defined by this ~mmi t t ee and, therefore, the Committee has chosen not to ~sume that these exposures are similar to a chemical flash fire nor

are the requirements for chemical flash fire protection adequate as minimum requirements for dust or particulate flash fire protection.

A-1-1.2 While this standard does not include specific test methods for measuring the performance of vapor-protective ensembles against biological agents, the inward leakage test has been included as a demonstration of vapor-protective ensemble resistance to inward leakage by airborne biological agents and the overall liquidtight integrity test is included as a demonstration of vapor-protective ensemble resistance to inward leakage by liquid biological agents.

A-l-l.4 Organizations responsible for specialized chemical response functions including radiological, biological, cryogenics, or fire-fighting applications should use protective clothing and equipment specifically designed for those activities.

A-1-2.2 The testing requirements in Chapter 6 of this standard are not intended to establish the limitations of the working environment for technical rescue but are intended to establish material performance.

Users should be advised that if unusual conditions prevail, or if there are signs of abuse or mutilation of the protective ensemble or any element or component thereof, or if modifications or replacements are made or accessories are added without authorization of the protective ensemble element manufacturer, the margin of protection might be reduced.

Users should be advised that the protective properties in new vapor-protective ensembles, as required by this standard, can diminish as the product is worn and ages.

1034

N F P A 1991 - - F 9 9 R O P

It is strongly recommended that purchasers of vapor-protective ensembles consider the following:

(a) Emergency response personnel must wear many items of protective clothing and equipment. Any interference by one item of another item's use might result in ineffident operations or unsafe situations.

(b) Different breathing apparatus, communications systems, cooling devices, and other protective equipment might not be equally accommodated by each vapor-protective suit.

(c) Specification of additional reinforcement in high-wear or load-bearing areas, such as the knees, elbows, shoulders, and back, can be necessary. Reinforcing materials should be the same as the suit material. Purchasers are cautioned that additional weight caused by excessive reinforcement could lead to fatigue or injury to the wearer ,'rod change or shorten the life of the suit.

A-I-3 Approved. The National Fire Protection Association does not approve, inspect, or certify any installation~, procedures, equipment, or materials; nor does it approve or evaluate testing laboratories. In determining the acceptability of installations, procedures, equipment, or materials, the authority having jurisdiction may base acceptance on compliance with NFPA or other appropriate standards. In the absence of such standards, said authority may require evidence of proper installation, procedure, or use. The authority having jurisdiction may also refer to the listings or labeling practices of an organization that is concerned with product evaluations and is thus in a position to determine compliance with appropriate standards for the current production of listed items.

A-l-3 Authority Having Jurisdiction. The phrase "authority having jurisdiction" 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 having jurisdiction may be a federal, state, local, or other regional department or individual such as a fire chief; fire marshal; chief of a fire prevention bureau, labor department, or health department; building official; electrical inspector; or others having statutory authority. For insurance purposes, an insurance inspection department, rating bureau, or other insurance company representative may be the authority having jurisdiction. In many circumstances, the property owner or his or her designated agent assumes the role of the authority having jurisdiction; at government installations, the commanding officer or departmental official may be the authority having j u r i s d i c t i o n . . , . '~*~"

A-l-3 Chemical Flash Fire. A policy of wearing p r o t e c ~ ¢ ) t h " is needed that recognizes the significant threat to fire can be exposed to flash fires in either structural fire-ill~ tin ~ hazardous materials environments. It is h o p e d ~ . ~ fi! utilize awareness training on burn injuries can of the environment. There is a distinct diffe~ ,et chemical flash fires and flashovers o c c u r d ~ . , s t r u c t ' fighting environments.

Flashover is a phenomenon that generates " he range of 650°C to 815°C (1200°F to 1500°F). A ~h fire requires an ignition source and a chemical atmospt ~at contains a concentration above the lower explosive l ~ i t of the chemical. Chemical flash fires generate heat from 546°C to 1040°C (1000°F to 1900°17). A structural fire flashover as a rule is confined to a designated area with walls as a boundary. A chemical flash fire depends on the size of the gas or vapor cloud and when ignited, the flame front expands outward in the form of a fireball. The resulting effect of the fireball's energy with respect to radiant heat significantly enlarges the hazard areas around the gas released.

A-I-3 Cryogenic Liquid. Examples of cryc)genic liquids include helium, nitrogen, and oxygen. This is not an inclusive list of cryogenic liquids.

A-I-$ Element(s). For the purposes of this standard, the suit is always an ensemble element, but the gloves and footwear can be either ensemble elements or individual elements. The ensemble elements, the components or subassemblies of the vapor-protective ensemble, include the suit, gloves, and footwear. The individual elements, separate compliant items but not part of the protective ensemble, are the gloves and footwear.

A-I-3 External Fittings. Airline, cooling device, and communications system connections or pass-through and glove

and boot interface materials on the chemical protective suit are examples of external fittings.

A-I-$ Hazardous Materials Emergencies. Hazardous materials emergencies are a special subset of activities during hazardous materials incidents. These emergencies are characterized as activity where significant hazards exist to personnel or the environment. Emergency activity takes place in the hot zone as opposed to support functions, which take place in the warm and cold zones.

A-l-3 Liquefied Gas. Examples of liquefied gases include ammonia, 1,2-butadiene, chlorine, ethylene oxide, hydrogen chloride, liquefied petroleum gas, and methyl chloride. This is not an inclusive list of liquefied gases. Testing in this standard is only conducted for a limited number of liquefied gases. Users should consult the technical data package to determine which liquefied gases have been tested vath the suit's primary materials. A-1-3 Listed. The means for identifying listed equipment may vary for each organization concerned with product evaluation, some of which do not recognize equipment as listed unless it is also labeled. The "authority having jurisdiction" should utilize the system employed by the lisfng organization to identify a listed product.

A-1-3 Vapor-Protective Ensemble with Additional Chemical Flash Fire Escape Protection. Ensembles meeting these requirements are intended to offer the wearer limited protection for escape only in situations that can result in chemical flash fires. This requirement does ng~ix~nply any protection for any fire-fighting acuvities but . ~ u m protection from the thermal effects of a chemical are wire no loss of suit gastight integrity.

~i~'~luirements of NFPA 1992, Standard on Liquid Splash-Protective .~Suits for Hazardous Chemical Emergencies.

A-2-1.8 The National Fire Protection Association (NFPA), from time to time, has received complaints that certain items of fire and emergency services protective clothing or protective equipment might be carrying labels falsely identifying them as compliant with an NFPA standard. The requirement for placing the certification organization's mark on the product label is to help ensure than the purchaser can readily determine compliance of the respective product through independent third-party certification.

A-2-2.3 The contractual provisions covering a certification program 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 the clauses, certifiers would not be able to move quickly to protect their name, marks, or reputation. A product safety certification program would be deficient without these contractual provisions and the administrative means to back them up.

A-2-2.4 Investigative procedures are important elements of an effective and meaningful product safety certification program. A preliminary review should be carried out on products submitted to the agency before any major testing is undertaken.

A-2-2.7 Such inspections should include, in most instances, witnessing of production tests. With certain products, the certification organization inspectors should select samples from the production line and submit them to the main laboratory for countercheck testing. With other products, it can be desirable to purchase samples in the open market for test purposes.

A-2-2.9 For further information and guidance on recall programs, see 21 C, FR 7, Subpart C.

A-2-3.10 Manufacturers are not limited in their approaches for designing vapor-protective ensembles compliant with this standard. If the suit design uses combinations of materials or garments to meet one part of the standard, then the same combinations must be assessed for all parts of the standard. For example, if a two-part visor is used such that the visor materials meet the chemical resistance requirement, the outer visor cannot be removed to meet the light transmission requirement. The same configuration must be used for all performance requirements.

A-2-6 ISO 9000 defines quality terms and concepts. It gives an overview of the content and use of the entire ISO 9000 series. A useful cross-reference to the series' quality system elements is found in Annex A of 1SO 9000.

ISO 9001, Quality Systems ~ Model for Quality Assurance in Design, Development, Production, Installation, and Servicing, is used when the quality system to be assessed covers several stages of one firm's processes. It prescribes quality system requirements for design, development, production, installation ano servicing.

ISO 9002, Quality Systems - - Model for Quality Assurance in Production, Installation, and Servidn~ focuses on quality system requirements for production and installation.

ISO 9003 details quality system requirements for final inspection and testing.

ISO 9004 is used for internal quality assurance purposes. It defines a basic set of elements that a company can use to develop and implement a quality management system. Guidance is provided on the technical, administrative, and human factors that affect the quality of products or services at all stages of operation. This standard can help companies determine the extent to which each quality system element applies to their organization.

A-5-1.1.7 Purchasers might wish to include a requirement in the purchase specifications for an additional label that includes certain information, such as the date of manufacture, manufacturer 's name, and suit identification number, to be located in a protected location on the suit in order to reduce the chance of label degradation and as a backup source of information to aid in suit tracking or during an investigation.

A-3-1.I.8 Examples of other clothing items that can be re~." ~e be worn for meeting performance criteria in this stand d ~ l "dud~ but are not limited to, over garments, over gloves, an W~.~ Purchasers must realize that all items specified by the ~ . manufacturer and used to determine compliance..wit~k,.this ~ , . standard, must be worn together.

ASTM F 1154, Practices for Qualitatively Evaluating'l~.~do?,~trt , Funaion, Fit, and Integrity of Chemical Protective S u i t ~ l e s . These practices entail having a test subject don the ~ and wear it during a series of exercises. Two exercise batteries are used. The first include a number of in-place exerdses such as toe touches, deep knee bends, and cross arm reaches that are intended to assess the subject's mobility and create stresses on different parts of the suit. The second involves more realistic acuvities such as crawling, climbing a ladder, turning a valve, operating a hand truck, and coiling a hose. These tasks attempt to simulate actions that an emergency responder might undertake during a hazardous materials emergency.

Purchasers and users should be aware that no reliable, nondestructive methods exist to determine the level of contamination for exposed yap.or-protective ensembles or their materials. Therefore, users will not be able to determine how effective decontamination methods are in removing chemical contamination from the vapor-protective suit. Vapor-protective ensembles that have received a significant exposure to a chemical or chemical mixture in the estimation of the responsible supervisor should be disposed of.

.4.-3-2.5 Purchasers should follow the instructions provided by the manufacturer for completing the logbook for their own means of recording suit use and maintenance and also for documenting levels of contamination when returning suits to the manufacturer.

The manufacturer should prepare the logbook so that it provides for at least the following data entries:

(a) Dates of each inspection, inspection findings, and the name of the inspector

(b) Dates of each use, the length of use, and the user's name (c) Names of chemicals the suit is exposed to including the

length and concentration of exposure (d) Dates of all repairs, including a description of the repairs,

and the name of the person making the repairs (e) Dates and types of decontamination the suit is subjected to,

and the name of the person or facility responsible for the decontamination

(f) Dates the suit is taken out of service and the reason for action (g) Dates the suit is returned to the manufacturer and the reason

for the return A-3-3.1.1 Purchasers should use the technical data package to compare suit performance data when purchasing vapor-protective ensembles. The purchaser should determine the relative ranking of performance data to aid in this selection process.

A-3-3.1.2 Purchasers should request that all documentation and performance data be provided in a format that will allow easy comparison of products to aid selection.

A-3-3.1.4 Manufacturers should determine the size range of their ensembles by matching human dimensions with available suit sizes. These determinations should account for other clothing and equipment to be worn by the wearer as recommended by the

A-6-8.5.13 One example of an appropriate analytical technique is NIOSH Method 6602, which uses a gas chromatograph equipped with an electron capture detector.

A-6-28.4.1 A TPP device meeting these requirements is available from Atlas Electric Devices Company, Fire Science Products, 4114 North Ravenswoord Avenue, Chicago, Illinois 60613.

A-6-28.4.2 A combination total calorimeter/radiometer Model 64P-5-24 from Medtherm Corporation, P.O. Box 412, Huntsville, AL 35804 has been found satisfactory for this purpose.

black paint applied to the calorimeter's surface. The calorimeter's finished mass should be determined by subtracting the sensor's thermocouple wire mass from the sensor's total mass. This is accomplished by measuring the sensor's thermocouple wire lengths from their ends down to the calorimeter's back surface Then the total wire mass should be calculated based on the number of wires and their lengths. This value should then be subtracted from the total mass of the calorimeter assembly to obtain the finished mass. After the finished mass is determined, the data transfer wires should be securely reconnected and the sensor repositioned in its support board.

A-6-28.5.2.7.1 Copper Calorimeter Calibration Procedures. Calibration of the copper calorimeter is based on the following equation:

1 ~ ~ 4 . 8 1 4 - - ( {MC}over{KA _ } ) ~ ( dT over dt )

where: / i s the incident heat flux, W/cm ~, 4.184 is the conversion factor to W/cm ~ from cal/crn~/s, dT/dt is the rate of temperature rise for the calorimeter, and (MC/KA_) represents the calorimeter's physical constant, which

includes the variables A, ~ and .M

M is the finished mass (g) of the calorimeter, which includes the copper disk and flat black paint mass on the sensing surface minus the thermocouple mass. C is the heat capacity of pure copper, which is 0.0927 cal/g°C. K is the thermocouple conversion constant (0.053 mv/°C) for the Type J, Iron-Constantan thermocouple at an average test temperature of 65°c. A is the surface area (12.49 an ~) ~'or the calorimeter's front surface, which is exposed to the test heat flux. __ is the emissivity or absorptivity of the black paint used on the calorimeter's front surface, usually a walue not less than 0.95.

The physical constant used in calibration calculations with these sensors is sensitive to changes in mass and /o r emissivity values.

For the copper disk calorimeter used in the TPP test, the punched-out and drilled copper slug mass must be between 17.5 and 18.0 g to meet the temperature rise over 1O-second rate requirement-

The calorimeter's physical constant can be calculated based on the above discussion. Check the repaired calorimeter's performance by substituting it with the calibration calorime.~'%- After proving equivalence, the test calorimeter can be plaJ~I"J~ into service. ~.~.~_:..
