b. Emergency Procedures. If NBC attack is known or suspected you should mask at once and continue
mission. If outside, follow decon procedures below to avoid taking contamination into controlled areas. Do
not unmask until told to do so.
(1) For nuclear decontamination, brush fallout from skin, clothing, and equipment with available
brushes, rags, and tree branches. Wash skin and have radiation check made so soon as tactical
situation permits.
(2) For biological decontamination, remain masked and continue mission until told to unmask.
(3) For chemical detection and decontamination:
Do not use decontamination spray on personnel. It could cause
personal injury.
(a) Use M8 paper from the M256 Chemical Agent Detector Kit or M9 paper to determine if liquid
agent is present on the equipment.
(b) If exposure to liquid agent is known or suspected, clean exposed skin, clothing, personal gear,
and equipment, in that order using M258Al kit. Use the buddy system. Wash exposed skin
and thoroughly decontaminate as soon as tactical situation permits.
(c) If the M8 or M9 paper indicates that liquid chemical agent is present on the equipment, use
the NBC-M11 decon apparatus for decon of equipment.
c. Operation During NBC (Nuclear, Biological, and Chemical) Hazard. When operation is anticipated
under potential NBC conditions, securely close the fresh air damper and seal the fresh air filter and
connect an NBC filtering unit (not a part of this air conditioner) to the auxiliary fresh air intake. See
specific instructions for your shelter or facility installation. If a NBC filtering unit is installed,
adjust the return air louvers in conjunction with the NBC filter controls to provide a higher
overpressure within the room or enclosure.
