Fire Extinguishers

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.
