WAC 296-305-03001   Hazardous materials protection.  (1) Structural fire fighting protective clothing shall not be used as primary protection for hazardous material incidents except as noted in the current edition of the Department of Transportation Emergency Response guidebook, which is incorporated by reference or shall be demonstrated by the employer to be equally effective.

     (2) Fire departments shall use the technical data package provided by the clothing manufacturer when selecting the hazardous chemical protection.

     (a) The approach to selecting personal protective clothing must encompass an ensemble of clothing items that are integrated to provide a level of protection and the ability to carry out emergency response activities.

     (b) The following is a check list of components that may form the chemical protective ensemble:

     (i) Protective clothing (suits, coveralls, hoods, gloves, boots)

     (ii) Respiratory equipment (SCBA)

     (iii) Cooling system (ice vest, air circulation, water circulation)

     (iv) Head protection

     (v) Inner garments

     (vi) Outer protection (overgloves, overboots, flashcovers)

     (3) Hazardous chemical protective equipment shall be classified by performance and for the purpose of this chapter are defined as:

     (a) Vapor-Protective Suits (Level "A")

     (b) Liquid Splash-Protective Suits (Level "B")

     (c) Support Function Protective Suits

     (4) Fire department personnel involved in hazardous materials incident shall be protected against potential chemical hazards. Chemical protective clothing shall be selected and used to protect the respiratory system, skin, eyes, face, hands, feet, head, and body.

     (5) Vapor protective and liquid splash-protective suits shall completely cover both the wearer and the wearer's breathing apparatus. Wearing a SCBA or other respiratory equipment outside the suit subjects this equipment to the chemically contaminated environment, increasing possible failure potentials and decontamination problems.

     (6) Fire fighters who engage in operations likely to result in significant exposure to vapors that can reasonably be presumed harmful by way of dermal exposure shall have available and make appropriate use of vapor protective suits. Vapor protective suits shall meet the requirements of NFPA, Standard on Vapor Suits for Hazardous Chemical Emergencies in 1991, 1990 edition, with the single exception that suits meeting all but the flammability standard may only be worn in atmospheres verified by means of appropriate air monitoring to be at no more than 10% of the lower explosive limit (LEL).

     (7) Prior to the use of vapor protective suits, liquid splash-protective suits or support function protective suits, the department shall consult the technical data package to assure that the garment is appropriate for the specific hazardous chemical emergency.

     (8) Vapor protective suits and liquid splash-protective suits shall not be used alone for any fire fighting applications or for protection from radiological, biological, or cryogenic agents or in flammable or explosive atmospheres.

     (9) Fire fighters who engage in operations or who are exposed to known chemicals in liquid-splash chemical environments during hazardous chemical material emergencies shall be provided with, and shall use, liquid splash-protective suits. Liquid splash-protective suits shall meet the requirements of NFPA, Standard on Liquid-Splash Protective Suits for Hazardous Chemical Emergencies 1992, 1991 edition.

     (10) Liquid splash-protective suits shall not be used when operations are likely to result in significant exposure to chemicals or specific chemical mixtures with known or suspected carcinogenicity as indicated by any one of the following documents if it can reasonably be expected that fire fighters in vapor protective suits would be significantly better protected:

     (a) N. Irving Sax, Dangerous Properties of Industrial Chemicals, current edition.

     (b) NIOSH Pocket Guide to Chemical Hazards, current edition.

     (c) U.S. Coast Guard Chemical Hazard Response Information System (CHRIS), Volumes 13, Hazardous Chemical Data.

     (11) Liquid splash-protective suits shall not be used when operations are likely to result in significant exposure to chemicals or specific chemical mixtures with skin toxicity notations as indicated by the American Conference of Government Industrial Hygienists (ACGIH), Threshold Limit Values and Biological Exposure Indices for 1988-1989 if it can reasonably be expected that fire fighters in vapor protective suits would be significantly better protected.

     (12) Support garments shall not be used in the hot zone of any hazardous material operation.

     (13) Fire fighters assigned to functional support operations outside the hot zone during hazardous chemical emergencies shall be provided with and shall use support function protective garments. Support function garments shall meet the requirements of NFPA, Standard on Support Function Protective Garments for Hazardous Chemical Operations 1993, 1990 edition.

     (14) Support function protective garments shall not be used for protection from chemical or specific chemical mixture with known or suspected carcinogenicity as indicated by (10)(a), (b), or (c).

     (15) Support function protective garments shall not be used for protection from chemicals or specific chemical mixtures with skin toxicity notations as indicated in the American Conference of Governmental Industrial Hygienists, Threshold Values and Biological Exposure Indices for 1988-1989.
