Water Extinguishers

Tikweld Welding Supplies and Services is the distributor of quality fire fighting equipment and accessories in Nigeria.

One way of successfully putting off the Class A fires is by using the water suppression system. Fire incidents fuelled by materials such as paper, wood, and textiles can be managed using this system.

There are various types of water extinguishers, and this includes Water mist, water with additives, water spray, and water jet.

Read on as we clarify each one of them;

• Water mist: This type of fire suppression system applies water in the form of mist, and the droplets are way smaller than that of the water spray system. This system absorbs heat faster because the droplet is smaller and larger the surface area, thus making the droplet evaporate quickly.

• Water jet extinguishers: This works by spraying a jet of water at the burning materials, thereby giving them a cooling effect and preventing re-ignition. This type of suppression system is not applicable to a powered electrical appliance.

• Water spray extinguishers: This type of water suppression system uses a very fine spray of water droplets that are surrounded by air, making it non-conductive.This type of water spray extinguisher usually carries a dielectric test approval of 35 kV, and it implies that it has been tested at one meter on a 35,000 Volt electrical source.

• Water extinguishers with additives: These are simply water extinguishers in which foaming chemicals are added, and as a result, the water loses its natural surface tension, and this implies that it can easily soak into the burning materials more effectively.

Kindly note that all water extinguishers have a red label.

How the Water Extinguisher Works

This works by having a cooling effect on the liquid that causes the burning fuel to burn at a very slow rate until the flames are successfully put off. The businesses or premises that require this extinguisher are buildings made of wood or organic material such as schools, hospitals, warehouses, offices, and residential properties.

Location

This type of extinguisher is required to be placed by the exit that has been identified for class A fire risk.
