Natural gas is a safe and clean source of energy used throughout campus, but like any gas, there is potential for it be released unintentionally. Your response to a natural gas leak will be to evacuate.
The University provides the following instructions to help UW personnel, students and visitors prepare for responding to an emergency on the Seattle campus. University units and departments can modify these instructions for their specific location(s) and add them to their Fire Safety and Evacuation Plans.
Natural Gas
Natural gas is flammable; a gas leak can lead to fire and explosion. Natural gas smells a little like rotten eggs; you can smell it even at very low concentrations. All natural gas odors should be treated seriously.
If you smell natural gas indoors
- Turn off all sources of ignition (open flames, electrical equipment).
- Laboratories: Check gas outlets for open valves and local gas tubing for leaks.
- On the Seattle campus, call UW Facilities at 206-685-1411 (answered 24/7) to investigate building systems and equipment for leaks.
indoor natural gas odor is strong, widespread, and/or quickly worsening
- Evacuate the area. Turn off all sources of ignition (open flames, electrical equipment) as you exit.
- Close local and emergency valves if present. Close all gas outlets and the emergency gas valve for your floor, laboratory, or area (if one exists).
- Activate the fire alarm. If the building is equipped with a fire alarm system, activate the alarm at a pull station.
- Stay out. Do not return to an evacuated building unless told to do so by the on-scene authority (fire department, police department or other authorized personnel).
If you smell natural gas outside
Call 9-1-1 when you smell strong odors or natural gas outdoors.
Other strong odors
Investigate whether the source is isolated in your area. If not, check the hallway and adjacent areas to determine if the odor is widespread.
Take action if the source is obvious and something can be done without putting anyone at risk. For example, eliminate or control the odor by moving a laboratory benchtop procedure to a fume hood.
