CO2 Fire Extinguisher

CO2 Fire Extinguisher Suitable For Class B & Electrical FiresCO2 (Carbon Dioxide) fire extinguishers are suitable for Class B fires which involve flammable liquids like petrol and oil and they can also be used on Electrical fires. CO2 gas is non-conductive which means it can be used on or in the vicinity of electrical equipment. It also contains a clean, non-toxic gas which leaves no mess after use.

CO2 extinguishers have a red body with a black panel at the top above the operating instructions. Another way of recognising them is that they don’t have a pressure gauge on the cylinder. They come equipped with a anti static horn that enables the operator to be in a safe position while the co2 gas is discharged. When the carbon dioxide gas is dispersed, it forms a white cloud which displaces the oxygen in the air and eventually extinguishes the fire.

The two most common sizes on the market are the 2kg and 5kg models. The 2kg extinguisher has a unique swivel horn that can cause freeze burns if held while using. The 5kg extinguisher is equipped with a hose and horn that is safe to be held close to the hose.

They are not effective on Class A fires which involve solid materials as they are unable to displace sufficient oxygen to extinguish the fire, leading it to reignite. They are also not suitable for Class D fires which involve burning metals as the co2 gas can react and blow burning metal everywhere, causing serious danger.

They are an environmentally friendly extinguisher as the carbon dioxide utilised is a recovered industrial by-product that minimises carbon levels.

CO2 extinguishers are perfect for use in offices, where they can be used on electrical fires, without the risk of equipment damage and extinguisher agent to clean up.

How It Works?

They basically work by suffocating the fire. The vaporising liquid gas covers the flames by displacing oxygen in the air.

The Features & Benefits

✓ Equipped with hose and horn (5kg) or swivel horn (2kg)

✓ Effective performance with excellent fire ratings

✓ Highly reliable

✓ Ideal for offices

✓ Eco-friendly non corrosive gas

✓ A non-conductor of electricity

✓ No residue will be left after use

✓ Has 10 years of use before an extended service needs to be performed

What’s Suitable?

CO2 extinguishers can be used on Class B and electrical fires. Class B fires include flammable liquids such as petrol, oil and paint. It’s unsuitable for chip pan fires as the powerful spray from the extinguisher will spread the burning fat causing the situation to be worse.

The Risks

These extinguishers have a limited cooling effect on the fire which needs to be carefully watched to prevent reignition.

If used in an enclosed area, it will reduce oxygen levels, making it hard to breath. It is advisable to wear breathing apparatus if being used in an enclosed space and ventilate the area as soon as the fire is under control and it is safe to do so.

Damage to skin tissue can happen due to dry ice that is formed under pressure whilst handling the horn during use.

Furthermore, carbon dioxide is a toxic gas that can asphyxiate and if concentrations are higher than 10%, it can cause a person to become unconscious within a minute.
