Safety Precautions

Gas leaks can cause explosions and expose you to carbon monoxide.*

When you see a large, yellow, flickering flame, or smell rotten eggs or sulfur, these may be signs that there is a problem with the equipment.

  • Immediately tell your supervisor and leave the building!
    • Do not turn any electrical switches or equipment on or off.
    • Do not use your phone.
    • Do not light any matches or smoke.
  • These could set off an explosion.

Do not return to the building until a trained authority tells you that the building is safe.


  1. If there is a gas leak:
    • Clear the building; leave doors and windows open.
    • Call 911 from a cell phone outside the building or a phone in another building.
    • Turn the gas supply off at the meter.
  2. To prevent gas leaks or exposure to carbon monoxide:
    • Make sure all gas equipment is installed and vented correctly.
    • Have all gas equipment (flues, pipes, connections and safety devices) maintained and checked regularly by a trained professional.


  • Never hang anything from gas pipes; this could loosen the fittings or cause damage to the pipes.
  • Always follow lockout/tagout* procedures for your facility.


  • Carbon Monoxide - Carbon monoxide is very toxic gas. It is colorless, odorless, tasteless, flammable. It is formed from incomplete burning of carbon, from products such as gasoline.
  • Lockout/Tagout - the standard that covers the servicing and maintenance o machines and equipment in which the uexpected energization or start up of the machine or equipment, or release of stored energy could cause injury to employees.
