16 Unit 3: Fire Extinguishers
The first fire extinguisher was invented in 1723 using an outer casing of extinguishing liquid with gunpowder internally, which when ignited, scattered the liquid. Today, almost every building has multiple fire extinguishers and it is important to know how to use one, when to use one and what type to use.
