OPERATE NBC AIR FILTER SYSTEM (M548A3) Continued
After Nuclear, Biological, or Chemical (NBC) exposure of the M548A3 carrier, handle all air
filters with extreme caution. Unit commander or officer in charge of personnel assigned to
remove and dispose of contaminated filters must prescribe necessary protective clothing to be
worn. Crew members may assist only if wearing protective clothing TB 10-277. Safety
measures including decontamination operation must be performed TM 3-220.
Failure to decontaminate and wear protective clothing could result in serious health hazards to
personnel. Unprotected personnel may experience injury or death if residual toxic agents or
radioactive material are present. If an M548A3 carrier is exposed to chemical or biological
agents, servicing personnel must wear protective overgarment, mask, hood, and chemical
protective gloves and boots. Place all contaminated air filters into double lined plastic bags.
Move them swiftly away from the work site. The same procedure applies for radioactive dust
contamination. However, the company NBC Team should measure radiation prior to filter
removal to determine extent of safety procedures required per NBC Annex to Unit Standard
Operation Procedures (SOP). The segregation area in which contaminated air filters are
temporarily stored must be marked with appropriate NBC placards. Make final disposal of
contaminated air filters in accordance with local SOP. NBC contaminated filters must be
handled using adequate precautions FM21-40 and must be disposed of by trained personnel.
Use extreme caution AT ALL TIMES when handling DS2. DS2 is a combustible solution.
Severe chemical burns can result if personnel fail to observe all safety precautions. DS2 can
damage eyes and skin, and if inhaled, can cause illness. DS2 can damage the NBC protective
overgarment. Long term contact with DS2 (about 24 hours) can damage the NBC protective
gloves, hood and overboots.
