Methyl salicylate(MeS) is used to simulate chemical agent vapor penetrationthrough ensemble interfaces and open

22、ings.4.2 This test method tests the vapor penetration and perme-ation resistance of a protective ensemble by the placement ofpassive adsorbent dosimeters (PADs) containing sorbent ma-terial onto the test subjects at specific locations on the body.4.3 After test subjects wearing the ensemble to be ev

23、aluatedfinish a series of activities inside the test chamber, these PADsare removed from the test subject and analyzed for MeS.4.4 Data obtained from the individual PADs are used toassess the vapor penetration and permeation resistance of theensemble at each body location and for the overall ensembl

24、e.5. Significance and Use5.1 This test method is intended to evaluate the penetrationand permeation resistance for complete ensembles to vaporsfrom chemical warfare agents and other chemical substances.5.1.1 This test method differs from Test Method F1052 byproviding an evaluation of ensembles worn

25、on human testsubjects and measuring the inward leakage of a chemical agentvapor simulant as it would be absorbed by the wearers skin.Test Method F1052 is not applicable to the range of protectiveensembles that are evaluated by this test method.5.1.2 This test method differs from Test Method F1359 by

26、using a chemical agent vapor simulant as compared to a liquidchallenge and in the use of human test subjects. This testmethod further provides a quantitative assessment of inwardleakage for the chemical agent vapor simulant.5.1.3 The use of this test method to determine the inwardleakage of other ch

27、emical vapor threats must be evaluated ona case-by-case basis.5.2 This test method is applied to complete ensemblesconsisting of a suit or garment in combination with gloves,footwear, respirators, and interface devices.5.2.1 This test method permits any combination or configu-ration of ensemble elem

28、ents and components, including en-sembles where the respirator covers the face or head.5.2.2 This test method accommodates protective ensemblesor protective clothing having any combination of the followingcharacteristics:(1) the protective ensemble or clothing is constructed of airpermeable, semiper

29、meable, or impermeable fabrics,(2) the protective ensemble or clothing is of a single ormulti-layered design, or(3) the protective ensemble or clothing is constructed ofinert or sorptive fabrics.5.3 MeS has been used as a simulant for chemical warfareagents. MeS is primarily a simulant for distilled

30、 mustard (HD)with a similar vapor pressure, density, and water solubility. Theuse of MeS in vapor form does not simulate all agents orhazardous substances to which ensemble wearers are poten-tially exposed.5.4 The principal results of this test are physiologicalprotective dosage factors that indicat

31、e the relative effectivenessof the ensemble in preventing the inward leakage of thechemical agent vapor simulant and its consequent dosage to thewearers skin as determined by the use and placement ofpersonal adsorbent devices (PAD) on human test subjects.5.4.1 Specific information on inward leakage

32、of chemicalagent vapor simulant is provided by local physiological pro-tective dosage factors for individual PAD locations to assist indetermining possible points of entry of the chemical agentvapor simulant into the ensemble.5.4.2 The determination of the local physiological protec-tive dosage fact

33、ors is based on ratio of the outside exposuredosage to the inside exposure dosage on the wearers skin atspecific locations of the body and accounts for the specificsusceptibility of the average humans skin at those locations tothe effects of blister agent, distilled mustard using the onset ofsymptom

34、s exposure dosages (OSED) at different points on thebody. The specific OSED values used in this test method arebased on the exposure concentration of distilled mustard thatcause threshold effects to the average individual human in theform of reversible skin ulceration and blistering (1).5.4.3 The bo

Additional locations are per-mitted to be us

The same PAD data are used in a body region hazard

40、 for CBRN Terrorism Incidents.5.4.6 The general procedures in this test method are basedon Test Operations Procedure (TOP 10-2-022), Man-In-Simulant Test (MIST) - Chemical Vapor Testing of Chemical/Biological Protective Suits.5.5 The human subject activities simulate possible causes ofchanges in ens

41、emble vapor barrier during expected activities.These activities are primarily based on stationary activitiesprovided in Part A of Practices F1154 and are intended tocreate movements that are likely to affect the integrity of theensemble and its interface areas. Additional activities (such asdragging

42、 a dummy and climbing a ladder) have been added tosimulate activities that might be used by first responders duringemergency events such as rescuing victims from a terrorismincident involving chemical agents. The test method permitsthe modification of the activity protocol to simulate the specificne

43、eds of the protective ensemble application.5.6 The length of the human subject exposure to thechemical agent vapor simulant is set at 30 min in the testchamber with a 5 min decontamination period. This testduration is intended to replicate a possible exposure of a firstresponder during a terrorism i

44、ncident involving chemicalagents. If a self-contained breathing apparatus is used, a60-min rated respirator must be used or provisions made forsupplemental umbilical air (through a supplied air system).Thetest method permits the adjustment of the exposure period tosimulate the specific needs of the

45、protective ensemble appli-cation.5.7 Test results generated by this test method are specific tothe ensemble being evaluated. Changing any part of theensemble necessitates a new set of testing for the modifiedensemble.5.8 Additional information on man-in-simulant testing isprovided in (3).6. Faciliti
