Title:DEFENCE AGAINST GAS (PART 3) [Allocated Title]
Film Number:ADM 2564-3-4
Other titles:PASSIVE DEFENCE [Series Title]
Summary: A naval instructional film describing the proper maintenance and use of respirators.
Description: The same format as ADM 2564-2. (The film warns against complacency because gas has not hitherto been used.) Practice should make donning the gas mask an almost automatic process. Proper adjustment of the head harness. Simple test for an air tight fit. Proper care and stowage of the gas mask canister. Importance of keeping clear the canister's air vents, and their proper alignment when in the haversack. Cleaning of the mask and eye pieces. Correct stowage of the mask to preserve its shape. Method of forming and wearing the anti-spray, plastic eyeshields. The government provides gas masks to preserve life, and they should therefore be kept in efficient order. Avoid abuse such as throwing the respirator, leaving it on a hot surface, etc. Periodic wear is advisable to flex the rubber and preserve a good fit. Do not keep sandwiches or tobacco in the container. Have confidence in your mask - it is proof against all known war gases. However, some "accidental gases", eg coal gas, require a Pattern 230 breathing apparatus. The film ends by recapitulating the cardinal points of proper gas mask procedure.
