What must accompany purging operations involving fuel gas?

Accompanying purging operations involving fuel gas with a combustible gas indicator is critical for safety. This device is designed to detect the presence of flammable gases in the atmosphere, ensuring that the concentration of gas remains within safe limits during the purging process. By using this indicator, operators can monitor for any leaks or dangerous levels of combustible gas, which helps prevent potential explosions or fire hazards.

Utilizing a combustible gas indicator is a standard safety protocol in gas handling and operations, as it provides real-time feedback about the environment. Ensuring a safe work area is paramount, especially in operations involving flammable materials, and this tool directly contributes to that goal. Other safety measures may be necessary, but the presence of a combustible gas indicator is specifically mandated to monitor and mitigate risks associated with fuel gas during purging operations.
