Smoking around
gasoline vapors increases the risk of an explosion, from the spark of a
lighter or the flame of a carelessly discarded match or cigarette.
The pilot lights in
the safest water heaters and furnaces are raised off the floor 12 to 18
inches. This lowers but does not eliminate the risk that gasoline vapor
concentrated on the floor of a basement or a garage could be ignited by a
pilot light flame.
Many people put
freezers or second refrigerators in basements or garages. They may use store
or gasoline nearby without realizing that the spark of a motor being turned
on by a thermostat could ignite gasoline vapor.
