ORI marches on
YOKOTA AIR BASE, Japan -- The MCU-2 Series Protective Mask must be inspected every seven days during contingency operations. Airmen should annotate the inspection on a DD Form 1574. The back of the form should include the date inspected, the initials of the inspector and the next inspection due date. The mask, with a C2A1 filter canister installed, is the first line of defense for an Airman's face, eyes and respiratory tract from chemical and biological warfare agents, radioactive dust particles and riot control agents.
