Masks Tested With Real Poison Gas, 1933

Tempting death daily is the lot of a few daring men in a London laboratory, where a steel-walled chamber containing an appreciable quantity of real poison gas is reported in use to test the air-purifying canisters of military gas masks.

Masked experimenters sit outside the deadly chamber, and breathe through hoses that terminate in the canisters within. A white-coated physician stands near to render first aid, in case the poison-absorbing chemicals should fail to function. Only in this way can new types of equipment be tested.

Photograph in circle shows English experimenters wearing gas masks and breathing poison gas coming from canisters set in a sealed room, 1933.
