A full-face mask refers to respiratory protective equipment that comes with full-facial protectors, such as helmets or masks. They protect the user from inhaling toxic substances, according to Healthy Working Lives.
There are several types of full-face masks available. The type of respiratory protection that should be used is dependant upon the working environment's air quality. Respirators act as a filtering device and should be worn when the air contains contaminants. However, if the working environment contains reduced oxygen levels, a breathing apparatus that provides clean air should be worn instead. The breathing apparatus should be supplied with clean air from a cylinder or an air compressor; it is not to be used as a filter, states Healthy Working Lives.
Both types of respiratory protectors can be used with various face coverings, such as masks, helmets, hoods and visors. When fitted properly, masks secure to the face with suction to provide a seal, and they are based on a specific wearers facial structure. Hoods, helmets and visors are loose-fitting and ideal for a wearer with facial hair or eye glasses. Full-face masks and respiratory protection should be used as a last resort. The employer is required by law to control the amount of exposure to hazardous or toxic substances, according to Healthy Working Lives.
