Potential Hazard
  • Possible employee exposure to corrosive exhaust gases, including hydrogen chloride. Gases such as hydrogen chloride can be irritating and corrosive to the eyes, skin, and mucous membranes. Exposure to high concentrations can cause laryngitis, bronchitis, and pulmonary edema.

Possible Solutions

  • Identify exhaust gas hazards and perform appropriate exposure evaluations.

    • Identify and evaluate all potential exposure scenarios, for example: startup, operations, maintenance, cleaning, emergencies, and so forth.

    • 29 CFR 1910.1000 Table Z-1 contains permissible exposure limits for various substances.
  • Provide appropriate ventilation to reduce gas concentration levels in the air.

  • Provide PPE [29 CFR 1910 Subpart I] as appropriate to prevent contact with exhaust gases.

  • Use respiratory protection [29 CFR 1910.134] when necessary to further reduce exposure and protect employees.
