Identify the hazard first
Determine the contaminant, concentration and work environment before selecting respiratory PPE. Employers should follow applicable OSHA requirements and the respirator manufacturer's instructions.
Half-face versus full-face respirators
Reusable half-face and full-face respirators serve different needs. Full-face models can add eye and face coverage, while the appropriate choice depends on the hazard assessment and required protection.
Filters and cartridges must match the hazard
Filters and cartridges are not interchangeable solutions for every contaminant. Use only components approved for the specific respirator system and application.
Fit matters
Tight-fitting respirators depend on an effective face seal and require proper fit testing and use practices.
