Which is the best method to extinguish a fire caused by an LPG regulator or pipe failure?

The best method to extinguish a fire caused by an LPG regulator or pipe failure is to close the main discharge valve on the cylinder. This approach is effective because it directly stops the flow of LPG, which is the fuel that can sustain and escalate the fire. By shutting off the main discharge valve, you reduce the fuel supply, allowing the fire to diminish and become more manageable.

In situations involving LPG, the primary hazard is the flammable gas that can ignite and cause unpredictable fiery situations. Closing the main valve interrupts this fuel source, minimizing the risk of explosion and further fire spread.

Other methods may not be as effective or safe. For instance, simply withdrawing and letting the fuel exhaust itself could be risky, as it might take too long for the fuel to burn off and there remains the potential for reignition or an uncontrolled fire scenario. Turning off the valve at the meter may also be ineffective if the fire is already intense or if the meter is not accessible. Using grounded pipe clamps to pinch the pipe closed is not a standard industry practice for extinguishing fires as it could lead to additional leaks or is not feasible in emergency situations.

Therefore, closing the main discharge valve on the cylinder remains the most reliable and immediate action to control an LPG
