WARNING

After Nuclear, Biological, or Chemical (NBC) exposure of vehicle, all air filters shall be handled

with extreme caution. Unprotected personnel may experience serious injury or death if residual

toxic agents or radioactive materials are present. If vehicle is exposed to chemical or biological

agents, servicing personnel shall wear protective mask, hood, protective overgarments, and

chemical protective gloves and boots in accordance with FM-3-4. All contaminated air filters

shall be placed in double-lined plastic bags and moved swiftly to a segregation area away from

the worksite. The same procedure applies for radioactive dust contamination. The Company

NBC team should measure radiation prior to filter removal to determine extent of safety

procedures required per the NBC Annex to the unit Standard Operating Procedures (SOP). The

segregation area in which the contaminated air filters are temporarily stored shall be marked

with appropriate NBC placards. Final disposal of contaminated air filters shall be in accordance

with local SOP. Decontamination operation shall be in accordance with FM-3-5 and local SOP.

Failure to comply may result in serious injury or death to personnel.
