What should be the first step in responding to a gas leak emergency?

In a gas leak emergency, the foremost priority is safety; thus, immediately evacuating the area is essential. People may be exposed to harmful gas that can lead to serious health hazards, including explosions or asphyxiation. By evacuating the area, individuals can move to a safe distance away from the potential danger, thereby minimizing the risk of exposure and ensuring their safety as well as that of others in the vicinity.

Once everyone is at a safe distance, it is appropriate to take additional steps such as calling emergency services to report the leak and allow trained professionals to handle the situation safely. Shutting off appliances or inspecting gas meters could pose additional risks in a dangerous environment, as interactions with potential gas sources may lead to igniting a fire or causing an explosion. Thus, prioritizing evacuation first is a critical and life-saving response.
