Which action is NOT recommended when using a fire extinguisher?

Standing too close to the fire when attempting to use a fire extinguisher is not recommended because it increases the risk of injury from heat, smoke, or flames. When using a fire extinguisher, it is crucial to position oneself at a safe distance, typically around 6 to 8 feet away from the base of the fire. This distance allows the operator to effectively aim the extinguisher while minimizing exposure to danger.

Aiming at the base of the fire is essential because that is where the fuel source is located, which is necessary for extinguishing the flames effectively. Reading the instructions before use ensures that the technician is familiar with how to operate the extinguisher properly and can respond quickly in an emergency. Finally, evacuating everyone after extinguishing the flames is a wise practice as it ensures safety in case the fire reignites or additional hazards are present.
