The Safety of Storing LPG in the Sun: Factors to Consider for Camper Enthusiasts

As a longtime camper, I've found that the storage of LPG (liquefied petroleum gas) in sunny conditions can be a cause for concern, but it is generally safe under certain conditions. This article explores the various factors and factors that influence the safe storage of LPG in direct sunlight and highlights best practices for campsite usage.

Understanding LPG Safety

LPG is stored in pressurized tanks that are designed to withstand high pressures and have safety features such as pressure relief valves that allow gas to escape if the pressure becomes too high due to heat. While LPG can tolerate some heat, it is crucial to ensure that the storage conditions do not exceed the manufacturer's recommended temperature limits.

Critical Safety Considerations

Pressure Relief

LPG tanks are equipped with pressure relief valves that open if the internal pressure becomes too high due to heat. These valves ensure that the pressure does not exceed a safe limit, greatly reducing the risk of tank rupture or explosion.

Temperature Limits

Temperature is one of the most critical factors to consider. Extreme temperatures can increase the pressure inside the tank. It is essential to ensure that the storage conditions do not exceed the manufacturer's recommended temperature limits to maintain the safety of the LPG storage system.

Ventilation

Proper ventilation is crucial for the safe storage of LPG. If a leak occurs, LPG is heavier than air and can accumulate in low-lying areas. Adequate ventilation helps disperse any leaked gas, reducing the risk of accumulation and potential ignition.

Material Safety

The materials used for LPG tanks are selected for their ability to withstand environmental conditions, including exposure to sunlight. Tanks are typically made from materials that resist corrosion and degradation from UV radiation. This durability ensures that the tanks remain safe even in sunny conditions.

Regulations and Guidelines

There are strict regulations governing the storage of LPG that consider environmental factors. Following these guidelines helps ensure safety. It is important to adhere to local and national regulations regarding the storage, handling, and use of LPG to minimize risks.

Personal Experiences and Observations

In my first camper, two LPG tanks (propane) faced directly South but were covered with a white vinyl cover. In the second camper, the tanks were on the North side and only received direct sun in the morning. Propane, a heavy gas, is not as flammable as gasoline. It sinks to the ground if there is a leak, while gasoline is lighter and more likely to travel around.

The cover in my campers was more a deterrent to theft or mischief than a protection against overheating. Older trailers often lacked covers, and no one worried about the sun heating them to the point of ignition. However, when gasoline is made, they aim for a certain octane; if there are fewer molecules with a chain smaller than an octane 8, gasoline is more likely to backfire or explode in the engine prematurely.

Comparison of LPG and Gasoline

LPG (propane) is a compressed gas and the steel tanks need to be very strong. So, provided the tanks are rust-free, they are very safe. In contrast, gasoline produces a lot of CO2 compared to propane, which is quite simple (C3H8). Burning propane produces a lot of water and only 3 CO2.

My wife quit camping because of some neighbors who insisted on bonfires in the middle of the night. Combining fire with trailers and camping fires can be a bad combination. It is crucial to prioritize safety and follow guidelines for the proper storage and handling of LPG to ensure a safe and enjoyable camping experience.
