Flammable, Explosive, 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 as appropriate to prevent contact with gases. [29 CFR 1910 Subpart I]
  • Use respiratory protection when necessary to further reduce exposure and protect employees. [29 CFR 1910.134]
  • 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.
