Which action is important to minimize fire risk at the scene of an accident?

Minimizing fire risk at the scene of an accident is crucial for ensuring the safety of all involved. The practice of enforcing a no smoking policy is particularly significant because the presence of flammable substances, such as fuel leakages from damaged vehicles, greatly increases the risk of fire. By prohibiting smoking, the likelihood of an ignition source coming into contact with these flammable materials is diminished.

This measure is especially important in an accident scenario where the potential for explosive reactions due to fuel vapors is heightened. When smoking is allowed, even a small spark can trigger a serious fire, endangering responders and victims alike.

In contrast, while other actions like disconnecting the battery or ventilating the area may contribute to fire safety in specific contexts, they are not as broadly impactful in preventing ignition sources as the outright ban on smoking.
