} Eliminate the sources of toxic gasses/vapors� Survey to insure hazardous materials are secure � Ensure that temperatures in the area are below 200 degrees

F. (cold fire, no hot spots, free burning or pyrolysis)} Provide for Ventilation◦ Conduct a minimum of 6 air exchanges in the area� Reduces any residual gasses/vapors through mechanical

ventilation} Conduct Air Monitoring◦ Initial to include the use of colorimetrics or equivalent◦ Continuous air monitoring with minimum 4 gas

electronic detector (LEL, Oxygen, Hydrogren Sulfide, Carbon Monoxide)

} (12) Prior to overhaul, buildings shall be surveyed for possible safety and health hazards. Firefighters shall be informed of hazards observed during the survey and measures shall be taken to protect firefighters from these hazards.

} (13) Self-contained breathing apparatus (SCBA) shall be worn throughout overhaul. SCBA shall also be worn during activities taking place in the area previously considered the hot zone after overhaul unless the officer in charge conducts an exposure evaluation to determine or reasonably estimate whether an employee is or could be exposed to either an airborne contaminant above a permissible exposure limit (PEL) listed in WAC 296-841-20025 Table 3 or other airborne hazards, such as biological/radiological/nuclear hazards. When the officer in charge cannot determine or reasonably estimate employee exposure they shall conclude that an atmosphere is hazardous to the employees in accordance with WAC 296-842-13005.

} (14) During the overhaul phase officers shall identify materials likely to contain asbestos, limiting the breaching of structural materials to that which is necessary to prevent rekindle.

} (15) Prior to removing firefighting ensembles worn in the hot zone, a gross decontamination shall be performed to remove potentially harmful contaminants.

} (16) Members of the department conducting post-fire investigations must comply with subsections (12) through (15) of this section

} Scope◦ . This chapter applies when your employees are,

or could be, exposed to an airborne◦ hazard◦ • The following are examples of airborne

contaminants that may become airborne◦ hazards in some workplaces:◦ – Chemicals listed in Table 3, Permissible

Exposure Limits (PELs) for Airborne◦ • Airborne contaminants exist in a variety of

physical forms such as dusts, fibers,◦ fogs, fumes, mists, gases, smoke, sprays, vapors,

or aerosols.

} Scope◦ 1) Respirators are required whenever respiratory

hazards (including oxygen-deficient◦ conditions) are present. For example, use respirators

at any of the following times:◦ (a) While exposure controls are being evaluated or put

in◦ place;◦ (b) When it is not feasible to use exposure controls to

remove or reduce the◦ airborne hazard to below the PEL.◦ (2) This chapter applies whenever respirators are used

at work.

} Infrared Thermometer (non contact) or TIC} Gastec PolyTec IV and Hydrogen Cyanide tube

(toxic inorganics/organics) or equivalent electronic detector

} Minimum 4 gas real-time electronic detector (Oxygen, LEL, Hydrogen Sulfide, and Carbon Monoxide)◦ Option – 5 gas to include Hydrogen Cyanide detector

} Turnouts and SCBA} Tyvek or better chemical protective clothing} Air purifying respirator with combination filter

(organic vapor acid gas HEPA filter)

} Has there been a safety survey of the area looking for possible hazards (asbestos, chemicals, radiologicals, structural integrity, etc.).

} Utilizing an Infrared Thermometer or TIC to ensure that all areas are less than 200 degrees F.

} Your initial evaluation will need to be conducted using turnouts and SCBA. Upon exiting the structure, gross decon must be conducted.

} Establish PPV with at least 6 air exchanges.◦ LxWxHx6/CFM of Ventilator x 0.6

(efficiency)=number of minutes of ventilation� L=Length of Building� W=Width of Building� H=Height of Building� 6=Number of air exchanges within structure/area� 0.6=Efficiency factor of the PPV

} Example◦ Structure interior is 80 ft long, 40 ft wide and 10 ft

tall◦ PPV fan is rated at 15,000 CFM◦ Using the formula of LxWxHx6/CFMx0.6= Min. of

Ventilation� 80x40x10x6/(15,000x0.6)=21 minutes

} Initial◦ Monitor for Inorganic/Organic Gasses

� Hydrogen Chloride, SOx, NOx, Ammonia, Hydrogen Fluoride, and Hydrogen Cyanide-none should be detected.

◦ Oxygen concentration outside equals inside� Remember every 1% decrease in oxygen means 50,000 ppm of

something else is in the air space.◦ Carbon Monoxide 0 ppm◦ Hydrogen Sulphide 0 ppm◦ LEL reading should indicate 0%

} Repeat the following every 30 minutes◦ Oxygen concentration outside equals inside

� Remember every 1% decrease in oxygen means 50,000 ppm of something else is in the air space.

◦ Carbon Monoxide 0 ppm◦ Hydrogen Sulphide 0 ppm◦ LEL reading should indicate 0%

} Air Purifying Respirator (APR)} Acid gas/organic vapor/HEPA cartridge} Limit cartridge to 6 hours max use and single

use only} Continue gas monitoring (Min 4 gas

electronic)} Wear Tyvek or higher chemical protective

clothing} Any changes in electronic air monitoring

requires the investigator to re-evaluate the atmosphere

} Process has been reviewed by Washington State Department of Labor and Industries◦ Found to be consistent with good practice

standards.} “This was discussed at the DOSH Fire Review

Board on 1/7/2016. There was consensus that this a conservative but workable framework for the fire investigator respirator downgrade.”
