3、, and transportation of chemicals canbe exposed to numerous substances capable of causing harm upon contact with the human body. Thedeleterious effects of these chemicals can range from acute trauma, such as dermatitis or burns, tochronic degenerative disease, such as cancer or pulmonary fibrosis. S

4、ince engineering controls maynot eliminate all possible exposures, attention is often given to reducing the potential for direct skincontact through the use of protective clothing that resists degradation, penetration, and permeation.Chemical-protective clothing ensembles range from outfits of glove

5、s, boots, and coveralls tototally-encapsulating chemical-protective suits employing self-contained or airline-supplied, or both,breathing apparatus. The ensemble of a chemical-protective suit in combination with gloves, boots, abreathing apparatus, and other auxiliary protective equipment can provid

6、e maximum protection towearers in situations when no contact with hazardous chemicals is permitted. Chemical-protectivesuits are often selected on the basis of material chemical resistance, but equally important are thecomfort, fit, functionality, and overall integrity of the suit allowing the weare

7、r to safely carry out hisor her assigned tasks. Few standards, if any, apply to the design and manufacture of chemical-protective suits. Additionally, protective suit designs vary depending on different end use applicationsin industrial settings, hazardous waste site clean up, and emergency response

8、. As a consequence, usersare faced with a variety of commercial products and generally depend on manufacturer salesinformation to decide which protective suits are appropriate for their own application. Other protectiveequipment such as gloves, boots, respiratory protective equipment, communications

9、 systems, andcooling devices must also be selected and integrated with the chemical-protective suit to provide anensemble with adequate protection.This standard is intended to provide standardized methods for qualitatively evaluating the comfort,fit, function, and integrity of chemical-protective su

10、it ensembles. It may also be used by protectiveclothing manufacturers to assess current or proposed suit designs.1. Scope1.1 These practices are intended for evaluating chemical-protective suit ensembles to determine the suitability of theensemble in a work environment on the basis of its comfort, f

11、it,function, and integrity.1.1.1 Option A is a manned exercise scenario intended totest the strength and durability of the garment material andseams.1.1.2 Option B is a manned work task scenario intended todetermine human factor characteristics and the ability of thesuited test subject to perform ta

12、sks that may be encountered ona routine basis in a typical work environment.1.2 These practices apply to all types of chemical-protectivesuits and auxiliary protective equipment including, but notlimited to, splash-protective suits, totally encapsulatingchemical-protective suits, and gas-tight, tota

13、lly encapsulatingchemical-protective suits.1.3 The values as stated in inch-pound units are to beregarded as the standard. The values in brackets are given forinformation only.1.4 This standard does not purport to address all of thesafety concerns, if any, associated with its use. It is theresponsib

14、ility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use. Specific safetyprecautions are given in Section 7.1These practices are under the jurisdiction of ASTM Committee F23 onProtective Clothing

Summary of Practices4.1 In Option A, the integrity of the chemical-protectivesuit, its materials and scams, are evaluated by subjecting theprotective ensemble to a manned exerc

28、ise scenario. The suit isinspected prior to and after the series of exercises to assess anychanges in the garments integrity.4.2 In Option B, the function of the chemical-protective suitensemble is evaluated by observing the ability of a test subjectto perform routine work tasks while wearing the pr

29、otectiveensemble. As in Procedure A, the suit is inspected prior to andafter the series of tasks to assess changes in the garmentsintegrity.4.3 For each option, the fit and comfort of the chemical-protective suit ensemble are assessed by measuring the testsubjects body dimensions and mass, and the d

30、imensions andmass of the ensemble. These measurements can be qualita-tively used to evaluate fit and comfort by relating test subjectand ensemble measurements to test subject responses follow-ing each test.5. Significance and Use5.1 These practices establish standard procedures designedfor qualitati

32、may use these practices to qualitativelydetermine how well specific chemical-protective suits andensemble components (gloves, boots, breathing apparatus,communications systems, and cooling devices) meet theirparticular application.5.2.2 Manufacturers of chemical-protective clothing andequipment may

Option B permits a qualitative evaluation ofchemical-protective suit ensemble function. Each procedurecan be used to assess chemical-protective suit ensemblecomfort and fit by

36、 relating test subject responses and bycomparing the dimensions and weights of both the test subjectand suit.NOTE 1The accumulation of suit and human subject dimension datamay eventually be used by manufacturers or end users in standards toimprove the sizing of chemical-protective suits and the inte

37、gration ofensemble components in protective ensembles.5.4 The use of these practices is for qualitative purposesonly. In general, results from use of these practices on one typeensemble may not be comparable to other test results on adifferent ensemble due to the subjective nature of test results.5.

38、5 These practices are not intended to assess heat stressresulting from wearing a chemical-protective suit ensemble,although thermal comfort of the suit ensemble may be subjec-tively evaluated.5.6 End users and manufacturers of chemical-protective suitensembles should consider these practices to be m

Users of these practices may wish to consideradditional tests and procedure that relate directly to theirparticular application. Each facility performing these practicesshould establish its own criteria for assessing acc
