Fire extinguisher type – the best extinguishers for your building
We look at the best fire extinguisher type for your workplace
So what is the best fire extinguisher type for your place of work. You will need different types depending on the risk in the building. Places of work must have at least one general purpose fire extinguisher for each 200 sq metres of floor space and also other types of extinguisher for other risks.
A general purpose fire extinguisher type is either a water or also a foam extinguisher. 3 litre general purpose fire extinguishers will put out 13A size fires. This means that the extinguisher is capable of putting out a fire 1.3metres x 1.3 metres x 1.2 metres of a Class A type fire. 3 Litre foam extinguishers with this rating should also put out a fire size 144B (1.44 metres in diameter liquid fuel fire).
So what other types of fire extinguisher are needed? Managers must thin about the other risks in a place of work. For an example an office will have computers and heaters etc so CO2 extinguishers should be in the area. 2 KG CO2 extinguishers are best for offices etc. 5 KG CO2 extinguishers are for use in factories and similar places of work. Workplaces with kitchens or who provide commercial cooking may need a Wet Chemical extinguisher if Class F materials (cooking oils) are used. Dry Powder extinguishers are sometimes found in boiler rooms but are not generally suitable for fighting fires indoors.
Fire extinguisher type example
Here is an example of what extinguishers a building would need. So fir instance, a three floor building with 700 sq metres of floor space per floor would need four general purpose fire extinguishers. They could be water or foam or also a mix of the two types. In addition, they would need carbon dioxide extinguishers if there was offices in the premises. They may consider a dry powder extinguisher for a boiler room.
