What type fire extinguishers are there




















The fire extinguisher contains Carbon Dioxide and once spray, it becomes dry ice to cover the fire. It can reduce the heat at instant and can put out the fire immediately, leaving no residues behind. It can be used for fire type B and C and is suitable in large production plants. The fire extinguisher is used for fire type A combustion to reduce the heat of the fuel derived from solid objects such as wood, paper, plastic, and fabric where it contains water and gas inside.

It is suitable for residents. Fire extinguishers that contain environment-safe volatile are for fire type A, B, C, and D where the substance does not harm objects or assets. It is suitable for computer rooms, communication device, manufacturing that involve electronics. The fire rating is used for determining capabilities to extinct the fire where it is regulated by Thai Industrial Standards Institute or TISI in order to control product quality and safety of users.

The standard is so called Thai Industrial Standard TIS which is label on the side of fire extinguisher where fire rating is set in order to compare and contrast effectiveness of the fire prevention and for the right usage.

Portable fire extinguishers must suitable for the following fuel and in accordance to the standards. Illustrates Fire Rating of fire type A: the higher number, the better capability to extinct fire type A. Illustrates Fire Rating of fire type B: the higher number, the better capability to extinct fire type B.

For fire type C, there is no Fire Rating but, on the label, it indicates clearly weather the fire extinguisher can extinct the fire type C. Fire Rating is an important indicator when selecting fire extinguishers as it is clearly standardise and certified.

In selecting fire extinguishers for buildings and business, types of fuel in accordance to capabilities to put out the fire should be taken into consideration. Moreover, sizes are important too as it needs to be relevant to the covered area so that it can be used at instant in case of fire.

Where to locate foam extinguishers: — By the exits on a floor where a Class A or Class B fire risk has been identified. This is because the powder can be easily inhaled, and also the residue is very difficult to clean up after. ABC powder extinguishers can also be used on some electrical fires. Specialist dry powder extinguishers are used for flammable metals. Use for: — Organic materials such as: o Paper and cardboard o Fabrics and textiles o Wood and coal Plus: — Flammable liquids, like paint and petrol Plus: — Flammable gases, like liquid petroleum gas LPG and acetylene Plus: — Fires involving electrical equipment up to v.

Specialist dry powder extinguishers are only used on flammable metals, such as titanium and magnesium. Do not use for: — Fires involving cooking oil — Fires involving electrical equipment over v — or in enclosed spaces, such as offices or residential properties.

How dry powder extinguishers work: Dry powder extinguishers smother fires by forming a barrier between the fuel and the source of oxygen. Where to locate Dry Powder extinguishers: — Place dry powder extinguishers near to the source of the fire risk.

Overview: CO2 fire extinguishers are predominantly used for electrical fire risks and are usually the main extinguisher type provided in computer server rooms. They also put out Class B fires flammable liquids, such as paint and petroleum. Use for: — Flammable liquids, like paint and petrol — Electrical fires. Do not use for: — Kitchen fires — especially chip-pan fires — Combustible materials like paper, wood or textiles — Flammable metals.

How CO2 extinguishers work: CO2 extinguishers suffocate fires by displacing the oxygen the fire needs to burn. Overview: Wet chemical fire extinguishers are designed for use on Class F fires, involving cooking oils and fats. Foam fire extinguishers can be used on Class A and B fires. They are most suited to extinguishing liquid fires such as petrol or diesel and are more versatile than water jet extinguishers because they can also be used on solids such as wood and paper.

The foam extinguishes liquid fires by sealing the surface of the liquid, preventing flammable vapour reaching the air and starving the fire of fuel. They are not suitable for use on free flowing liquid fires. Powder extinguishers are a good multi-purpose fire extinguisher because they can be used on Class A, B and C fires.

They can also be used on fires involving electrical equipment however, they do not cool the fire so it can re-ignite. Powder extinguishers can also create a loss of visibility and may create breathing problems.

They are not generally recommended for use inside buildings unless there is absolutely no alternative. CO2 extinguishers are ideal for places with a lot of electrical equipment such as offices or server rooms because they are safe to use on fires involving electrical apparatus. Carbon dioxide extinguishers do not leave any residue, unlike a foam extinguisher. They can also be used on Class B fires, those involving flammable liquids such paraffin or petrol. CO2 extinguishers work by smothering the fire and cutting off the supply of air.

Wet chemical extinguishers are suitable for use on Class F fires involving cooking oils and fats, such as lard, olive oil, sunflower oil, maize oil and butter. They are extremely effective, when used correctly. The wet chemical rapidly knocks the flames out, cools the burning oil and chemically reacts to form a soap-like solution, sealing the surface and preventing re-ignition. Although they are primarily designed for use on Class F fires, cooking oils and deep fat fryers.

They can also be used on Class A fires wood, paper and fabrics and Class B fires flammable liquids.
