For safe use and storage of gasoline, only use metal or plastic containers, place the container on the ground when filling, avoid overfilling the can, keep the container closed, and store it away from flames, sparks and heat sources. Never siphon gasoline by mouth, and avoid breathing the vapors it produces.
While gasoline is important for everyday life, it is highly flammable and dangerous. Inhaling the fumes can cause brain damage, and an exploding gasoline container can cause serious burns or even death. Store gasoline in containers made specifically for this purpose. Do not reuse other types of containers for storing gasoline.
Sitting the gas can on the ground when filling insures proper grounding. When filling the can, pump the gas slowly to prevent the buildup of static electricity.
Service stations often store gasoline in underground containers, where it is cooler than the ambient temperature. It expands when it warms, so observe the maximum fill line on the container. Avoid storing gasoline inside a vehicle where high temperatures could lead to a spill.
The fuel is highly volatile and flammable. Storing in a hot location increases the number of fumes it produces. If these fumes come in contact with an open flame or spark, they can ignite the entire contents of the container, causing explosions.
