Why is it important to avoid overfilling LP gas tanks?

Avoiding overfilling LP gas tanks is critical due to the potential for excessive pressure and leaks. LP gas, or liquid propane, expands when it warms up. If a tank is filled beyond its designated capacity, there is not enough space for this expanded gas, which can lead to increased pressure within the tank. This heightened pressure can exceed the safety limits of the tank and other components, potentially causing leaks. A leak in an LP gas system poses serious safety hazards, including the risk of fire or explosion, making proper filling procedures essential for safe operation.

In relation to this issue, other factors such as deterioration of tank material or the lifespan of the gas may be relevant, but they do not directly capture the immediate dangers posed by overfilling. Efficiency also may be affected but is not the primary reason for maintaining correct fill levels. The focus on controlling pressure highlights the necessity for safe handling and usage of LP gas, thus ensuring both operational safety and compliance with regulations.
