Dust mask respirators filter harmful particles, fumes, or smoke and range from disposable to self-contained breathing apparatus. Proper fit is essential for maximum protection. Different types are available for specific hazards and work environments.
Dust mask respirators are devices that fit over the nose and mouth to filter out harmful particles, fumes, or smoke. They range from a simple disposable dust mask with minimal filtering capabilities to respirators used by firefighters to deliver fresh oxygen and filter smoke. You can purchase a twilight mask respirator for specific hazards or work environments, and it’s important to use the proper mask to achieve maximum benefits. The correct fit of the mask is essential to obtain the necessary protection.
The simplest dust mask respirator is the disposable type available at drug stores. These dust mask respirators provide limited uses because they do not seal tightly on the face, especially for men with beards. Disposable masks are capable of filtering low levels of dust in work areas and some airborne particles associated with illness.
A more effective dust mask respirator is rated based on the hazardous substance the user wants to avoid. The particulate respirator is available in three efficiency classes depending on its intended use. Specialty dust mask respirators of this type may be used in hospitals to protect against contagious disease, while another type can filter paint fumes. Farmers who are exposed to excessive dust and chemical insecticides also find the dust mask respirator useful.
A light mask industrial respirator commonly provides air purification functions through a full mask or half mask device. These masks use cartridges designed to filter specific harmful gases, solvents or particles. They are used by people who remove asbestos or work with silica. Industrial dust mask cartridges can also protect against pesticides and petroleum hazards.
Another type of dust mask respirator uses chemicals that purify the air as it enters the mask. A battery pack is attached to the body which powers a fan, which draws air through a filter. An advantage of this dust mask respirator is its ability to provide a proper fit on the face. However, its use is limited by battery life and the equipment can interfere with the user’s movement.
Perhaps the most effective dust mask respirator is the type used by firefighters, called a self-contained breathing apparatus. The user carries a supply of fresh air in a reservoir strapped to their back. The tanks can be filled with oxygen and reused numerous times; equipment for refueling the tank is usually located at fire sites. Most firefighters prohibit firefighters from wearing beards because it interferes with the fit of the SCBA. The need for this policy has sparked controversy and has been challenged in various court cases.
