In a garage, unenclosed equipment that may produce arcs or sparks must be placed at least what height above the floor?

In a garage, unenclosed equipment that may produce arcs or sparks is required to be installed at least 12 feet above the floor to minimize the risk of ignition of flammable vapors or materials that may be present at ground level. This height requirement is established in electrical code regulations to enhance safety. By positioning such equipment higher, it reduces the likelihood that any arcs or sparks will come into contact with potentially hazardous substances found in garages, such as gasoline or oil, which could lead to fire or explosion hazards. This measure is particularly important in environments where volatile substances are stored or may accumulate, ensuring compliance with safety standards designed to protect both individuals and property.
