Any appliance with an ignition source and located in a hazardous location, such as garages, must have the ignition source located how far above the floor?

In hazardous locations such as garages, it is essential to ensure that any appliances with an ignition source are installed at a safe height above the floor to prevent accidental ignition of flammable vapors that may accumulate near the ground. The correct height for placing these ignition sources is 18 inches above the floor. This standard helps protect against the potential risks posed by gasoline vapors or other flammable materials that could be present in the space.

The height of 18 inches is specified in various building and safety codes to ensure safety in areas where flammable materials are commonly stored and used. By elevating ignition sources above this threshold, the likelihood of ignition is minimized, supporting overall safety and compliance with regulatory guidelines.
