A full face respirator is a piece of safety equipment designed to limit exposure to hazardous substances in the air. Full face coverage protects the respiratory system and the eyes from things like particulates, dangerous fumes, and other substances that may be present in the air. Such devices come in a number of styles and can be worn with other safety equipment like hoods and protective garments for more complete protection from specific hazards.
The full face respirator includes several components. A clear panel fits over the eyes to allow people to see while providing eye protection, and a protective component covers the nose and mouth. Rubberized seals around the edges of the respirator prevent ambient air from getting inside, keeping the inside of the respirator cleared of contaminants. Straps are used to fix the device firmly to the head and in some cases, the full face respirator comes with an attached hood to cover the head.
In a filtering respirator, canisters are worn to filter air from the room when the person breathes in. These devices are suitable for many types of environments, including construction sites. Other respirators attach to an oxygen supply worn on the body. This type of full face respirator is used when there are concerns about unknown contaminants or when contaminants cannot be effectively filtered. People working on virus research, for example, cannot rely on filters alone for a safe air supply.
Disposable full face respirators are available for situations where the devices need to be quickly distributed, such as emergencies where police officers and fire crews are responding to a situation. Devices intended for repeat use tend to be more durable and can also be sterilized for cleanliness between uses. Likewise, their canisters are replaceable if they are filter respirators, allowing people to exchange clogged or worn canisters.
In some work environments, a full face respirator is required by law for the health and safety of workers. This safety requirement is intended to reduce the risks of disease, injury, and death caused by hazardous working conditions. In others, such devices are not required, but they may be recommended and strongly encouraged. Company policies can require full face respirator use if the law does not, and safety auditors regularly check to confirm that safety regulations and policies are being followed. Employees who violate the requirements may be suspended or fired, depending on workplace safety policies.
