Storing gasoline and other highly flammable liquids at home is also
dangerous if not done properly. The best way to store gasoline is in a
well ventilated area separate from the house. The location should have
no electrical equipment, open flames or other sources of ignition
present. In addition, the location should be protected from the heat
of the summer sun to keep evaporation to a minimum.
