What is the first action you should take if a gas leak occurs?

When a gas leak occurs, the priority is to ensure the safety of all individuals in the vicinity. Turning off the gas flow is a critical initial action because it helps to stop the continuing release of gas, which can prevent further hazards such as explosions or fires. By securing the gas supply, you mitigate immediate risks and can create a safer environment for evacuation and emergency response.

While evacuating the area is also important, the first action in terms of addressing the leak itself is to stop the source of gas flow if it is safe to do so. Calling emergency services and locating the source may come shortly after this step, but the urgent need to control the gas flow takes precedence to quickly reduce the overall danger from the leak.
