WARNINGS
Do not use the breathing apparatus for chemical-biological agent protection In atmospheres where the use of
impermeable protective clothing is required.
Do not use the breathing apparatus in an explosive gas atmosphere
Never allow any substance to enter the canister neck-especially oil, gasoline, or grease. The canister contains oxygen-
producing chemicals which will cause flammable material to burn. Keep the outside of the canister, the foil seal, and the
inside of the plunger valve assembly free of moisture, oil, dirt, or grease.
Do not use the canister after the initial preset time has elapsed. Once the oxygen starts generating in the canister, it will
continue as long as moisture and carbon dioxide are in the canister or until the oxygen-producing chemical is expended,
even if the apparatus is not being worn. The canister must be replaced before using the apparatus again.
Do not touch the bottom of the quick-starting canister with bare hands after starting apparatus. It will be hot. Wear
gloves to protect the hands.
Make sure that the apparatus is supplying oxygen and that all its connections are tight before entering a contaminated
area.
Return to fresh air immediately after the timer rings. Remove the facepiece or change canisters in fresh air only.
The timer works independently of the functioning of the apparatus or the breathing rate of the wearer. Each user must
learn from personal experience the indications and feeling when a canister is no longer capable of generating oxygen.
Canisters contain Potassium Superoxide which is a chemical that is extremely corrosive to all body tissues with direct
contact. Exposure to this chemical is highly unlikely during normal use of the canister, however, used canisters must be
handled as hazardous waste to avoid the possibility of future environmental health hazards.
DO NOT throw away used canisters in ordinary trash.
DO turn in used canisters to your hazardous waste management office or Defense
Reutilization and Marketing Office (DRMO).
Disposal of hazardous waste is restricted by the Resource Conservation and Recovery
Act as amended (42 U.S.C.A. sec 6901 et seq). Violation of these laws is subject to
severe criminal penalties
Return to fresh air before investigating or correcting any malfunctions in the breathing apparatus.
