Gasoline should always, be tightly sealed in an approved container, kept out of the house and out of the reach of children. Seal both the spout on the container and the vent.

And never keep gasoline anywhere in the house. Keep it away from the ignition sources, in a detached garage or shed, keep it tightly sealed and away from children.

Gasoline Safety Can Fire - California

A highway construction worker was moving equipment from the back of a flatbed truck. In the process of moving the equipment, he also moved a 3-gallon gasoline safety can which spilled gasoline onto his pants. A propane-fired tar furnace is believed to have ignited the spilled gasoline and set the construction worker on fire. The primary issue in the case is whether or not the gasoline safety can was defective. It was determined that an internal (non-visible) valve closure disk had come loose which allowed the gasoline to spill out of the can. Other issues involved labeling, warnings, and DOT and OSHA Regulations.
