This high quality 3.5kg CO2 (carbon dioxide) fire extinguisher is supplied with a wall bracket, a fire extinguisher location sign, and a CO2 fire extinguisher identification sign. The fire extinguisher features a hose with horn type nozzle end. Due to the fire extinguishers weight, it will require mounting on a solid wall.

When to use:-

The 3.5kg CO2 (carbon dioxide) fire extinguisher can be used for the following:

Class B fires – Flammable and combustible liquids
Class E fires – Electrically energised equipment

Where to use:-

This 3.5kg CO2 fire extinguisher is primarily used for electrically energised equipment fires but is safe for flammable and combustible liquid fires. CO2 is a clean agent extinguishing agent which leaves no residue and is therefore ideal for use in sensitive equipment areas such as server rooms, laboratories and office areas with a high density of computers. The fire extinguisher works by displacing the oxygen from the fire and cooling.

This fire extinguisher can also be used in conjunction with a plain air / water fire extinguisher to cover an office environment.

Where not to use:-

It's important to note, this 3.5kg CO2 fire extinguisher can reduce oxygen in very enclosed areas, leading to breathing problems. The extinguishing agent is very cold when deployed so may cause thermal shock and damage in some instances. It can also cause frostbite if discharged at a person.

The effectiveness of this fire extinguisher is also reduced in areas that have air moving freely through them.
