What must be done to the torch valve and gas supply if torch operation is to be discontinued for one hour or more?

In the context of safe torch operations, if torch operation is to be discontinued for one hour or more, it is essential to close the torch valve and shut off the gas supply. This procedure ensures that there is no unnecessary risk of gas leakage, which can create hazardous conditions. By closing the torch valve, you prevent gas from leaking through the system, and shutting off the gas supply eliminates any potential for gas accumulation that could lead to accidents or explosions.

This process adheres to safety protocols and minimizes the risk of fire hazards while the torch is not in use. Properly securing the equipment aligns with best practices in torch operations, ensuring a safe working environment for everyone involved.
