What safety practice should be followed when using the PASS method?

Using the PASS method for operating a fire extinguisher involves several important steps: Pull the pin, Aim the nozzle, Squeeze the handle, and Sweep the nozzle from side to side. Among these steps, ensuring clear escape routes is crucial for safety while extinguishing a fire.

Maintaining a clear escape route allows the user to exit the area quickly if the fire cannot be controlled or if it begins to spread. This is especially important in emergency situations where seconds matter. If the fire becomes too dangerous, having a clear exit path can prevent injury or becoming trapped.

The other options may not directly contribute to the effective use of the PASS method. Aiming high at the fire could be ineffective since most fires involve flames that rise; effective extinguishing requires aiming at the base of the flames. Pacing oneself during use isn't a specific safety measure tied to the PASS method. Standing too close to the fire can increase the risk of injury and should be avoided; the correct approach is to maintain a safe distance while using the extinguisher. Thus, ensuring clear escape routes is the most critical safety practice to follow when using the PASS method.
