Gas mask

The gas mask is a mask used to protect the user from inhaling airborne pollutants and toxic gases. The mask forms a sealed cover over the nose and mouth, but may also cover the eyes and other vulnerable soft tissues of the face. Some gas masks are also respirators, though the word gas mask is often used to refer to military equipment (e.g. field protective mask). The user of the gas mask is not protected from gas that the skin can absorb. Most gas mask filters will last around 24 hours in a nuclear biological chemical (NBC) situation.

GAS DRILL AT A LONDON HOSPITAL: GAS MASKS FOR BABIES ARE TESTED, ENGLAND, 1940. Three nurses put on their gas masks, whilst a fourth nurse attends to the gas masks of two babies in the cot in front of her. Adults were told to put on their own gas mask before helping children or other adults with theirs.
