Main types of fire extinguishers
ABC Dry Powder Fire Extinguishers
The fire suppression agent in these fire extinguishers is a specialised chemical dry powder, which is designed for putting out Class A, B and C fires. The agent is stored in pressurized cylinders with nozzles to discharge it to the fire upon release. The fire extinguisher can extinguish fires caused by flammable solids, liquids and gas.

The key property of this fire suppression agent is that it rapidly sucks out oxygen from flames, thereby stopping the fires quickly and safely.

The extinguishers can also be effective on Class A fires resulting from burning clothes and paper materials. The fire suppression agent in the cylinder fights the flames by eliminating the heat element, cooling the oils and creating a soapy solution that seals off the surfaces. The not only stops the fires but, also prevent them from re-ignition.

The agent works by removing oxygen from the chemical reaction, hence, stopping the flames. Foam fire extinguishers are usually very messy on electrical fires and should never be used in such situations. Besides, the chemical composition of the foam can also cause damage to your electrical systems.
Water-Based Fire Extinguishers

Water mainly works by eliminating the heat element from the flames, which cools off the burning materials and stops the fire.
