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 use any phones, electric switches, doorbells, thermostats or appliance controls. All of these devices, including battery-operated equipment, can cause sparks and ignite natural gas. Avoid creating static electricity; do not step on doormats or shuffle across carpet.
