Under what circumstances must an LP-Gas system be shut down?

An LP-Gas system must be shut down during maintenance, leaks, or severe weather events to ensure safety and prevent potential hazards. Regular maintenance is essential for the system's efficient and safe operation, and shutting it down allows technicians to perform necessary repairs or inspections without the risk of gas leaks or explosions.

In the event of leaks, immediate shutdown is crucial to mitigate the danger posed by the escaping gas, which can create a fire risk or lead to harmful inhalation. Severe weather events, such as hurricanes or tornadoes, may also necessitate a system shutdown to prevent damage or ensure safety during emergency conditions.

Understanding these scenarios emphasizes the importance of proactively managing LP-Gas systems to ensure that they are safe to operate under various conditions. The other options suggest circumstances that do not align with the established safety protocols for LP-Gas systems.
