Fire Extinguisher Suitable for use in Corridors

Corridors are an essential part of any escape route and should be kept clear of obstructions. They usually contain limited fire risks but are a key location to fire extinguisher access from adjoining rooms.

General Risks - Foam Fire Extinguishers

Most corridors will have general fire risks from things such as carpets, wooden door and furniture.

Fire Classifications

Class A - Suitable for solid combustible materials such as wood and textiles, these materials are often found in corridors in the form of doors, notice boards, furniture and carpets.
Class B - Suitable for flammable liquids such as petrol and oil, these materials are often found in corridors in the form of furniture polish and cleaning materials which are left on cleaning carts.

Advantages:

Foam fire extinguishers prevent the re-ignition of burning substances. They have excellent penetration properties and do not impair visibility when discharged.

Disadvantages:

Foam is an electrical conductor making foam fire extinguishers unsuitable for use on electrical fires.

Electrical Risks - CO2 Fire Extinguishers

In many corridors there are electrical boxes located on walls and often adjoining rooms containing electrical fire risks.

Fire Classifications

Class B - Suitable for flammable liquids such as petrol and oil, these materials are often found in corridors in the form of furniture polish and cleaning materials which are left on cleaning carts.
Electrical - Suitable for use on electrical fires such as computers and printers which are often found in adjoining rooms to corridors. Also suitable use on things such as electrical heaters which are often found in corridors themselves.

Advantages:

CO2 does not conduct electricity and is a clean extinguisher agent which leaves behind no harmful residue.

Disadvantages:

CO2 is an asphyxiant if used in confined spaces and cannot be used on solid fuel fires such as wood, paper or textile.

General Risks - Water Mist Fire Extinguishers

Most corridors will have general fire risks from things such as carpets, wooden door and furniture.

Fire Classifications

Water mist fire extinguishers are suitable for use on class A, B, C, F and Electrical risks and are ideal for use in corridors as multi-purpose extinguishers.

Advantages:

The water mist effectively suffocates burning materials, cooling them and leaving very little residue behind. The water mist turns into steam and evaporates upon contact with the fire.

Disadvantages:

Although the water mist extinguishers cover most types of fire the fire ratings for each class of fire are lower than their traditional counterparts (water, foam, powder and CO2).
