When Every Breath Counts: How Respirators Keep You Safe in Toxic Workspaces

When engineering controls are not feasible, workers must use appropriate respirators to protect against adverse health effects caused by breathing air contaminated with harmful dust and debris, fogs, fumes, mist, gases, smoke sprays, or vapors. Respirators generally cover the nose and mouth or the entire face or head and help prevent illness and injury. For respirators to be effective, a proper fit is essential and must be verified through a fit test. Required respirators must be NIOSH approved, and medical evaluation and training must be provided before use. For additional information concerning OSHA's PPE requirements related to respiratory protection, refer to 29 CFR 1910.134, Part 1910, Section 134, or ask about our respiratory protection specific training.
