Engineering and work practice controls are used to help manage or eliminate risks from respiratory hazards, and for those risks that we can’t eliminate 100%, we use personal protective equipment. Respirators are among the most important pieces of protective equipment for working in hazardous environments. They protect you from inhaling dangerous substances, such as chemicals and infectious particles. Selecting the right respirator requires first figuring out the types of hazard in the workplace and choosing the most appropriate respirator.
