A fire extinguisher is a portable device used to put out small fires. It contains a special substance that can smother flames, making it an essential safety tool in homes, offices, and vehicles. Different types of extinguishers are designed for various kinds of fires, such as those caused by wood, paper, grease, or electrical equipment. Knowing how to use one can save lives and property. To operate a fire extinguisher, remember the acronym PASS: Pull the pin, Aim the nozzle, Squeeze the handle, and Sweep from side to side. Regularly checking your extinguisher ensures it is ready for use in case of an emergency. Always keep it in an accessible location, away from potential fire hazards.
