What are the prescribed emergency procedures upon detecting a gas leak?

The correct response highlights the importance of safety when dealing with a gas leak. Upon detecting a gas leak, the priority should always be to leave the area as quickly and safely as possible. This minimizes the risk of exposure to potentially harmful gas and prevents the chance of ignition, as gas can be highly flammable.

Avoiding ignition sources is crucial because any spark, flame, or heat could escalate the situation and lead to an explosion or fire. Hastily vacating the premises ensures that individuals are cleared from the hazardous environment where dangerous levels of gas may be present.

In contrast to the other options, which do not prioritize immediate safety effectively, this response correctly emphasizes quick action and maintaining a safe distance from any potential ignition risks. For example, informing neighbors and continuing daily activities exposes individuals to risk. Turning off appliances or opening windows may not be feasible or safe in the presence of a significant leak, while calling a friend to inspect the area can further endanger someone who could be unnecessarily exposed to the gas.
