A Fire Bucket is filled with sand or water and is used to extinguish fires.
Sand is often used where there is a risk of spilled flammable liquid which might ignite and spread by flowing across the ground.
The sand is deployed to act as a barrier to the flowing liquid. Both plastic and metal fire buckets are available.
They are easy to use, no training is required, all one has to do is to grab it, fill it with sand or water and throw it at the flames.
Foam type fire extinguishers
Foam extinguishers are used to extinguish Class B fires and are located near flammable liquids.
There can be two types of foam type fire extinguishers depending upon its contents- A) Chemical foam type fire extinguisher B) Mechanical foam type fire extinguisher
These extinguishers work by creating a cooling effect on the fuel that is responsible for causing the fire.
When it is poured on burning liquid, the fire is extinguished by creating a barrier between the fuel and the flame with the help of the foaming agent which blankets oxygen.
Dry Chemical Powder fire extinguishers
A Sodium bicarbonate powder is used to extinguish almost all types of fires.
It is mainly located near electrical equipment.
Dry powder extinguisher contains sodium bicarbonate powder in the outer container.
Small container with carbon dioxide is placed beneath the plunger mechanism. When the plunger is pushed, it releases the carbon dioxide gas, which in turn forces the dry powder out of the discharge nozzle.
It can be used for class A, class B and class C fires.
Carbon dioxide fire extinguishers
Carbon dioxide extinguishers are mainly used for class B or class C fires.
They are not used for accommodation areas and confined spaces because of the gas used in lethal. These are widely used as electrical fire extinguisher.
Carbon dioxide is stored in liquid form under pressure. A central tube acts as an outlet for carbon dioxide gas.
A plunger attached to a bursting disc at one end and a trigger at the other is used to release the carbon dioxide gas. The liquid changes to gas as it comes out of the extinguisher through a Hose.
CO2 extinguishers are mainly used for electrical fire risks. They also put out Class B fires.
