Step-by-step explanation:
Before approaching the fire with a portable fire extinguisher, there are important safety measures and preparational steps that should be taken. Firstly, ensure that you know how to properly use the extinguisher by familiarizing yourself with the PASS technique: Pull the pin, aim low, squeeze the lever slowly and evenly, and sweep the nozzle from side to side.
Additionally, it is critical to assess the environment for safety, ensure there are no hazardous materials that could react to the extinguisher, make sure the area is well-ventilated, and plan an escape route in case the fire becomes uncontrollable. Also, wear protective gear if available, such as gloves and a mask, to keep yourself safe from heat, smoke, and fumes. Always be mindful of the fire’s behavior and stay alert while approaching it. Lastly, communication is key. Work closely with your buddy, keep a safe distance from the fire as recommended for your extinguisher type, and be prepared to evacuate immediately if the situation escalates beyond your capacity to control it.
