Outdoor gas leaks: Control ignition hazards
Keep vehicles and apparatus parked upwind, out of the path of the leak and 50 to 200 feet away. Do not use spark-producing equipment, and discourage its use by others. Use only intrinsically safe radios and flashlights during the incident response.
Do not ring doorbells, use garage door openers, or turn electrical switches on and off. Do not step on doormats or shuffle across carpet.
