Gas appliances should be securely mounted so that they are not susceptible to movement. Natural gas water heaters, in particular, should be anchored to a wall or post, not only to prevent breakage of gas piping, but also to preserve a supply of water. Excess flow valves Excess flow valves, which are not activated by ground vibration, are available upon request. For more information, check out our Products and Services for Your Home section. If you have natural gas fireplace logs with a key-operated gas valve, remove the key from the valve when not in use and put it in a safe place.

Vapors from paint thinner, gasoline, cleaning solvents and contact cement, to name a few, can catch fire or explode if exposed to a flame or spark. When you use flammable liquids, do so in an open, well-ventilated area, far away from any possible source of ignition.
