How high above a garage floor must ignition sources be positioned?

Ignition sources must be positioned at least 18 inches above the garage floor. This requirement is essential to prevent accidental ignition of flammable vapors that may accumulate in low areas, such as the floor of a garage where gasoline and other flammable substances are commonly stored or used. By placing ignition sources at this height, there is a reduced risk of igniting any vapors that can drift near the ground, maintaining a safer environment in garages where vehicles, power tools, and fuel may be present. This guideline is designed to adhere to safety standards and to minimize the risk of fire hazards in areas prone to flammable materials.
