Quick Answer
Fuel stored in direct sunlight can heat up rapidly and increase the risk of fire or explosion. This is particularly concerning for volatile fuels like gasoline or propane.
Volatile Fuels and Sunlight
Fuels like gasoline, propane, or diesel can experience thermal expansion, leading to increased pressure and a higher risk of rupture or leak. When exposed to direct sunlight, these fuels can heat up by as much as 20°F (11°C) in just 30 minutes. This rapid temperature increase can cause the fuel to become more volatile and prone to ignition.
Storage and Shadow Considerations
To minimize the risks associated with fuel storage in sunlight, it’s essential to consider the location and protection of the storage area. Providing shade using canopies, umbrellas, or buildings can help reduce the temperature increase and prevent fuel from becoming too hot. For example, a simple awning can block 70-80% of direct sunlight, depending on its angle and material. When selecting a storage location, look for areas with natural shade or consider installing a solar-blocking screen to reduce heat gain.
Best Practices for Fuel Storage
In addition to providing shade, it’s crucial to follow best practices for fuel storage, including using approved containers with secure lids, keeping fuels at least 20 feet away from any ignition sources, and following manufacturer guidelines for storage and handling. Regular inspections of fuel storage areas should also be conducted to ensure the integrity of containers and the overall storage setup.
