WARNING
After Chemical, Biological, Radiological, and Nuclear (CBRN) exposure of vehicle, all air
filters shall be handled with extreme caution to avoid exposure to residual toxic agents or
radioactive materials.
If vehicle is exposed to chemical or biological agents, servicing personnel shall wear
protective mask, hood, protective overgarments, chemical protective gloves, and boots.
All contaminated air filters shall be placed into double-lined plastic bags and swiftly moved
to a segregation area away from the work site.
The same procedure applies for radioactive dust contamination; however, the CBRN team
should measure the radiation before filter removal to determine the extent of the safety
procedures required per the CBRN Annex to the Standard Operating Procedures (SOP).
The segregation area in which the contaminated air filters are temporarily stored shall be
marked with appropriate CBRN placards.
Final disposal of contaminated air filters shall be in accordance with local SOP. Failure to
comply may result in personnel death, injury, and/or damage to equipment.
CAUTION
Do not hit filter on a hard surface to clean. Damage to the seals may occur which will allow
dirt to enter the engine and degrade performance. Failure to comply may result in damage
to equipment.
