What should be done if gas is burning outside?

In the scenario where gas is burning outside, the most appropriate action is to call for additional resources. This is because a burning gas leak can be highly dangerous and poses risks of explosion, particularly if the fire spreads or if there are people nearby. Emergency responders are better equipped to handle such situations safely, utilizing specialized equipment and training to mitigate the hazards associated with gas fires.

While it's crucial to ensure the safety of individuals in the vicinity, simply evacuating nearby buildings or applying water could potentially exacerbate the situation, as water is typically not effective against gas fires and might create additional hazards. In some cases, doing nothing can be safer if it minimizes the risk of igniting the gas or spreading the fire. Hence, involving professional help is essential to strategize effective actions and ensure safety in the presence of fire caused by gas.
