Water Fire Extinguishers

Ensure your water fire extinguisher is always ready when you need it by checking it regularly. Monthly in-house checks should be conducted by YOU. We can then ensure that it is sited correctly, still has an anti-tamper device fitted and any gauge is reading correctly.

      how to use a fire extinguisher
      How do Water Fire Extinguishers Work?

      Also known as a Class A extinguisher, water fire extinguishers work by cooling the fire to the point where it can no longer sustain itself. The water does this by taking away the heat that is necessary for the fire to continue burning.

      Without this heat, the fire will eventually go out on its own. This is why it is important to aim the nozzle of a water extinguisher at the base of the fire. This is where the heat is coming from and where the water will have the most effect.

      What Colour is a Water Fire Extinguisher?

      The water extinguisher is entirely red with white writing on the cylinder.

      Can Water Extinguishers be Used on Electrical Fires?

      The short answer is no; water and electricity do not mix. Never try to put out an electrical fire with water, as this could spread the flames, cause potential electrocution and put you and others in danger.

      The standard water unit expels in a single jet that can then conduct along the stream. There are some water extinguishers on the market that claim to be safe to use on electrical fires, however, we would advise that whether it is the jet application or the water left standing on the floor, a conductivity issue is present.

      Do I Need Fire Extinguishers for my Business?

      Any business with 5 or more employee’s needs a Fire Risk Assessment completing by law. Your fire risk assessment will outline the types of extinguishers your business needs depending on the potential risks.

      If you’re still unsure book a free, no obligation consultation with one of our Fire Protection Consultants. They’ll be able to advise you on what you need to protect your business.
