f. Spillage. Care should be taken that fuel is not spilled. Any spillage should be removed promptly.
g. Safety cans. Safety cans should be used, if possible, for storing small quantities of gasoline, as they have covers that must be forcibly held open to remove or add gasoline.
h. Rags. Metal receptacles with metal lids should be provided for discarded, oily, or gasoline-soaked rags. These rags must be disposed of daily.
i. Electrical apparatus. Vaporproof incandescent electric lamps, switches, and other appliances of approved type should be used. Open switches, relays, and similar apparatus, or motors with commutators, must not be used where gasoline fumes may be encountered.
j. Hose. Flexible metal, rubber, and rubber-metal hose should be inspected regularly (at least four times a year) and discarded when noticeably deteriorated.
k. Toxic fumes. Gasoline fumes are somewhat toxic and should not be inhaled.
l. Leaks. Leaks must never be neglected, and the fact that gasoline is a dangerous liquid must always be kept in mind. Inspections for leaks should be made frequently, particularly at pipe and hose joints.
m. Fire extinguishers. Carbon tetrachloride, carbon dioxide, or foam-type fire extinguishers should be provided and located where they will be accessible in the event of fire. Sand, not water, should be thrown on burning fuel if suitable extinguishers are not available.
n. Leaded gasoline. Gasoline often contains a poisonous lead compound. Such gasoline, or fuel containing leaded gasoline, should not be allowed to touch the body, especially the lips, eyes, open cuts, and sores.
