A gas mask is a mask used to protect the wearer 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. Most gas masks are also respirators, though the wordĀ gas maskĀ 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.
Airborne toxic materials may be gaseous (for example,Ā sulfur mustardĀ andĀ chlorine gas) or particulates (such asĀ biological agents). Many gas masks include protection from both types. Gas masks are used in construction to protect against welding fumes, in demolition to protect againstĀ asbestosĀ or other hazardous particles, and in the chemical industry when handlingĀ hazardous materials, as in making repairs to leaking equipment or cleaning up after spills; workers are usually issued gas masks as a precaution against leaks.
During demonstrations and protests whereĀ tear gasĀ orĀ CS gasĀ is employed by riot police, gas masks are commonly used by police and demonstrators alike. Aside from serving their functional purposes, gas masks are also used as emblems inĀ industrial music, with the most notable example, theĀ subgenreĀ ofĀ drum and bassĀ calledĀ neurofunk. These emblems are used byĀ graffitiĀ taggers because the mask protects them from the paint canisterāsĀ toxic fumes, and byĀ urban explorersĀ venturing into environments where hazardous materials, such as asbestos, may be present.
The traditional gas mask style with two small circular eye windows originated when the only suitable material for these eye windows wasĀ glassĀ orĀ acrylic; as glass is notoriously brittle, glass eye windows had to be kept small and thick. Later, the discovery ofĀ polycarbonateĀ allowed for gas masks with a large full-face window. Some have one or two filters attached to the face mask while others have a large filter connected to the face mask with a hose that is sometimes confused with anĀ air-suppliedĀ respiratorĀ in which an alternate supply of fresh air is delivered.
