A portable fire extinguisher is a handheld device used to extinguish small fires. Portable fire extinguishers come in different types, each designed for specific types of fires, such as fires involving electrical equipment, flammable liquids, or cooking oils. To use a portable fire extinguisher: Pull the pin: This will break the tamper seal and allow you to use the fire extinguisher. Aim the nozzle: Point the nozzle at the base of the fire, not at the flames. Squeeze the handle: This will release the extinguishing agent. Sweep the nozzle: Move the nozzle from side to side to cover the entire fire. It is important to remember that portable fire extinguishers are only suitable for small fires. If a fire is too large or spreading quickly, evacuate the building immediately and call the fire department.
