What should be done first with piped gas during an emergency?

Shutting off the gas is the first and most critical action to take during an emergency involving piped gas. This step is essential because it helps prevent further leakage or the potential for an explosion. By stopping the flow of gas, the risk of fire or an explosion is significantly reduced, creating a safer environment for anyone present.

After shutting off the gas, appropriate additional actions, such as notifying the fire department and evacuating the building, can be undertaken. Ventilation may also be necessary if there is still gas present in the area. However, these actions should follow the immediate step of eliminating the source of the hazard by shutting off the gas supply. Prioritizing this action can protect lives and property by minimizing the dangers associated with gas leaks.
