If a propane tank starts to leak, what should be done?

When a propane tank begins to leak, the most important action is to prioritize safety. Evacuating the area ensures that individuals are removed from a potentially dangerous situation where flammable gas is present. Propane leaks can lead to severe hazards, including explosions or inhalation risks, depending on the concentration of propane and the environment.

After ensuring that everyone has safely distanced themselves from the leak, contacting emergency services is crucial. Professional responders have the training and equipment necessary to handle gas leaks safely. They can assess the situation accurately and take the necessary measures to mitigate the danger.

The other actions listed could worsen the situation. Sealing a leak with tape is not advisable, as it is a temporary and unreliable fix that does not address the source of the gas release. Turning off the gas supply might be applicable if it's safe to do so; however, if the leak is causing a significant risk, it may not be the best initial action. Attempting to fix the leak oneself can also lead to dangerous situations, as it may involve working close to the leak and increasing exposure to the gas or igniting it inadvertently. Therefore, evacuating and contacting emergency services remains the most responsible course of action when dealing with a propane leak.
