About the respiratory protection standard
- Employers must provide to each employee an applicable and suitable respirator
- The employer must establish and maintain a written respirator program
- The program must be administered by a trained, qualified individual
- Respirators, training, and medical evaluations shall be provided at no cost
Contaminated air
- Immediately Dangerous to Life or Health (IDLH)
- Chemical and biological substances
- Asphyxiant atmospheres
Respiration
Engineering Controls
