Water fire extinguishers are the cheapest to buy, replace and refill. And it’s no wonder; the extinguishing agent is hardly costly to buy.
Who should use them?
Water fire extinguishers are commonly found in shops, due to the high level of packaging and clothing kept in stock.
However, many other businesses choose to have a water fire extinguisher present in addition to other extinguishers they need; if a Class A fire does break out, it’ll be cheaper to use and replace a water fire extinguisher than it would be to replace a multi-class one.
