Respirator gas masks protect against harmful gases and chemicals, with filter cartridges designed to neutralize specific hazards. They are commonly used in laboratories, industry, and by military and police personnel. Proper use and specific filters are essential for full protection.
A respirator gas mask is safety equipment designed specifically to protect the wearer from harmful gases and airborne chemicals. These devices use a filter cartridge to deactivate or remove hazardous chemicals and require specific filters to be effective against particular chemicals. Such devices are commonly used as laboratory and industrial safety equipment and can also be used by military or police personnel. Proper use of this type of equipment is essential to ensure that it functions properly and is fully protected.
Respirators come in many different varieties. Typical designs fit snugly around the user’s mouth and nose and should form an airtight seal with the skin. These devices allow air to flow only through a special set of filters. Many models, especially those designed to protect against chemicals that can damage or irritate the skin, also include eye protection. Most hazardous substances will also cause adverse skin reactions and full body protection is required to supplement the protection afforded by a respirator gas mask.
Each type of respirator protects against a particular type of hazard. A particulate respirator, like an asbestos respirator, is designed to filter small but dangerous particles from the air. Pathogen protection is the primary function of a medical respirator. A respirator gas mask specifically protects against airborne chemicals, which typically need to be neutralized and absorbed rather than filtered.
The most common varieties of respirator gas masks rely on the mask user breathing to draw air through the filter. This can be very tiring and is especially challenging for users who have difficulty breathing. Some sophisticated types of respirator gas masks use a motor-driven pump to draw air through the cartridge and then deliver a supply of this clean air to the mask wearer.
In a respirator gas mask, the filter component of the device consists of a cartridge designed to neutralize a specific chemical hazard. These cartridges are only valid against specific hazard categories and do not offer generalized protection against all chemical hazards. A respirator gas mask filter cartridge degrades with use and offers only limited protection. In many cases, these cartridges work by using other chemicals to neutralize a particular toxin, and when the cartridge’s chemical supply is depleted, it will no longer offer protection.
Most respirator gas masks are used to provide occupational protection or emergency safety protection for workers who may be exposed to hazardous chemicals in the workplace. Even soldiers and police forces can use these masks. Chemical weapons are prohibited under international law, but stockpiles still exist in many nations, and this type of protection remains as necessary on the modern battlefield as it was during World War I. Police forces require this type of protection primarily when using chemical crowd control agents.
