A gas mask (Polish MUA model pictured) is a mask used to protect the user from inhaling airborne pollutants and toxic gases. It forms a sealed cover over the wearer's nose and mouth, but may also cover the eyes and other vulnerable soft tissues of the face. Most gas masks are also respirators, though the term gas mask is often used to refer to military equipment (e.g. a field protective mask). Gas masks do not protect from gas that the skin can absorb.Photograph: Nikodem Nijaki
