What emergency action should be taken if LP gas is smelled indoors?

The appropriate emergency action when LP gas is detected indoors is to evacuate and call for help. This response prioritizes safety by removing individuals from a potentially hazardous environment where an explosion or fire could occur. Evacuating ensures that everyone is a safe distance away from the gas leak, which is crucial since LP gas is highly flammable and can lead to serious dangers if ignited.

Calling for help means notifying emergency services, who are trained to handle gas leaks safely and can properly assess the situation and take necessary actions, such as shutting off the gas supply or ventilating the area.

In contrast, checking appliances does not address the immediate danger posed by a gas leak and may expose individuals to further risk. Turning on ceiling fans could potentially circulate gas, increasing the risk of ignition, while lighting a match is extremely dangerous and would create a serious fire hazard. Therefore, the most prudent and safe action is to evacuate and seek assistance.
