Water Extinguisher

Water Extinguishers

Water extinguishers are the most common fire extinguisher type for class A fire risk. Most premises will require either water or foam extinguishers.

Label Colour:
– Bright Red

Use for:
– Organic materials such as:
o Paper and cardboard
o Fabrics and textiles
o Wood and coal

Do not use for:
– Fires involving electrical equipment
– Kitchen fires
– Flammable gas and liquids

How water extinguishers work:
The water has a cooling effect on the fuel, causing it to burn much more slowly until the flames are eventually extinguished.

Types of premises/business who may need water extinguishers:
– Buildings constructed of wood or other organic materials
– Premises where there are organic materials to be found such as:
o Offices
o Schools
o Hospitals
o Residential properties
o Warehouses

In fact most buildings need either water or foam extinguishers.

Where to locate water extinguishers:
– By the exits on a floor where a Class A fire risk has been identified

Water spray extinguishers – what’s the difference?:
Water spray extinguishers are equipped with a spray nozzle, rather than a jet nozzle, meaning a greater surface area can be covered more quickly and the fire put out more rapidly.

Water mist extinguishers – what’s the difference?:
Water mist extinguishers have a different type of nozzle again which releases microscopic water particles. These particles ‘suffocate’ the fire and also create a wall of mist between the fire and the person using the extinguisher, reducing the feeling of heat.
