ANS) Confined spaces are risky because as such there is deficiency in oxygen and any fire in the confined space will further use all the oxygen, Halon type fire extinguishers work on breaking the chain reaction, and volume required to extinguish fires is very less, and also this leaves no residue, only problem is that it is a CFC
What is the exact fire extinguisher used in confined spaces?
Mitigate the use of extinguishers in enclosed spaces with a health and safety risk assessment as per BS 5306-8. A fire extinguisher is only suitable for the risk it is approved for.

Can carbon dioxide be used as a fire extinguisher?
Carbon dioxide extinguishers are best used for electric (E) fires. They don’t contain water and won’t damage surrounding equipment like powder extinguishers. They can also be used on small class B (liquid) fires, but cooling effects on the liquid are limited and the fire may re-ignite after it has been extinguished.
Is it possible to extinguish all types of fire at once?
No. There are many types of fire, some cannot be extinguished at all. If the fire does not need oxygen, and continues burning even if the materials are cooled to or below room temperature, there is not much that could be done other than waiting till the fire burns itself out. Metals are particularly nasty when burning.
