Hazardous Gas

(flammable, toxic, corrosive, oxygen, cryogenic)

Natural Gas Odor

Odorant, added to natural gas, can be detected at extremely low concentrations. Smelling natural gas does not necessarily constitute an immediate hazard. If gas odor is detected:

  1. Call 911. Report:
    • Name and phone number
    • Building and room number
    • Area of odor
    • How long odor has been noticed

Compressed Gas Cylinder

If a cylinder is leaking, and in the judgment of the person responsible for the cylinder, the valve cannot be closed, and an immediate hazard exists:

  1. Turn on any exhaust ventilation and close all doors when exiting laboratory or shop.
  2. Call 911. Report:
    • Name and phone number
    • Building
    • Room number where cylinder is located
    • Name of gas leaking

Implement building evacuation. Move to a safe distance and leave clear access for emergency personnel. Do not return to the building until instructed by a safety official.
