Fire Extinguishers
About Fire Extinguishers
Everyone has seen a fire extinguisher a some time or another. Fire extinguishers can be found just about everywhere: at work, at home, or in your car. However, many people do not have a good working knowledge of fire extinguishers. In the hands of an improperly trained person, a fire extinguisher could be dangerous or even make the fire worse. Fire extinguishers were designed to be used as a first line of defense in the event of a small fire.
