Flammable, Explosive, and Pyrophoric Gases
Potential Hazard
  • Possible ignition of flammable, explosive, and pyrophoric gases, resulting in fire or explosion.

  • Employees may also be exposed to gases above permissible limits.
Possible Solutions
  • Identify and eliminate possible ignition sources. Use a Process Hazard Analysis (PHA) for identifying and controlling such hazards.

  • Provide appropriate ventilation to reduce gas concentration levels in the air.

  • Provide PPE [1910 Subpart I] as appropriate to prevent contact with gases.

  • Use respiratory protection [1910.134] when necessary to further reduce exposure and protect employees.

  • Use gas monitoring systems with automatic shut-offs and alarm systems, as appropriate.

  • Design and use specialized processing, material handling, and storage equipment for gases. Consider both normal use and emergency scenarios.
