Summary: A film based on the assumption that chemical warfare has started and that the enemy are employing gas: members of the Royal Air Force (at an unnamed airfield) demonstrate the procedures to be taken in such an event.
Description: Once the presence of gas has been detected, the reactions at various parts of the airfield are shown: the sentry giving the alarm, the orderly room staff, prisoners, telephone operator, machine gunner, airmen and aircraft fitters. Signals are given warning pilots to take care when landing. The various areas are shown again after a bomb has landed; men are seen going into the decontamination centre. All their clothing must be removed before the gas mask can be taken off. The eyes are the first to be treated, then bleach cream is applied to the body. Th men then receive a clean uniform and respirator. The Gas Defence and Decontamination Centres are shown, great stress being laid on the fact that they should always be ready for a possible attack. Once the Gas Officer and Commanding Officer have decided that the attack is over then decontamination can start. All incidents are noted and marked. The film also shows the situation caused by different bombs. The brick building and hangar are shown having bleach paste applied to them. The squad report to decontamination centre for treatment, the film using one of them as an example. He is undressed, his eyes irrigated, he has a shower and collects his new clothing. Final footage is of the demontamination plant treating the contaminated clothes.
