Classification of Fires by Type


The current British/European Standard BS EN 2:1992
Classification of fires defines four categories of fire, according to the type of material burning.

Class A
These are fires on solid materials, usually organic, leaving glowing embers. Class 'A' fires are the most common and the most effective extinguishing agent is generally water in the form of a jet or spray.

Class B
These are fires involving liquids or liquefiable solids. For the purpose of choosing effective extinguishing agents, flammable liquids may be divided into two groups: those that mix (are miscible) with water and those that do not (are immiscible). Extinguishing agents are chosen according to whether the liquid fuel will mix with water or not. Agents which may be used include water spray, foam, light water, vaporising liquids, carbon dioxide and dry chemical powders.

Class C
These are fires involving gases or liquefied gases in the form of a liquid spillage, or a liquid or gas leak, and these include methane, propane, butane, etc. Foam or dry chemical powder can be used to control fires involving shallow liquid spills, though water in the form of spray is generally used to cool the containers.

Class D
These are fires involving metals. Extinguishing agents containing water are ineffective, and even dangerous. Carbon dioxide or dry chemical powders containing bicarbonate will also be hazardous if applied to most metal fires. Powdered graphite, powdered talc, soda ash, limestone and dry sand are normally suitable for Class D fires. Special fusible powders have been developed for fires involving some metals, especially the radioactive ones.

Dangerous Substance Control Ltd

Thank you for the presentation at the event yesterday, everyone I spoke to thoroughly enjoyed it


Dangerous Substance Control Ltd

I attended the monthly meet yesterday and would like to thank you for one of the best, and most entertaining, sessions I have seen in a long while. It was most entertaining and extremely informative. I am sure I speak for many other safety professionals who, during their training, only get to read or be told about the fire triangle, flammable substances, and explosions. The session you delivered yesterday provided a fantastic insight into the subject and gave practical demonstrations of such things as LEL and UEL.


Dangerous Substance Control Ltd

Just a quick note to say thank-you for your excellent presentation and demonstration yesterday - definitely provided the high impact that we were looking for in terms of a training / awareness event for the attendees. We will definitely be exploring opportunities to invite you back to reach a wider audience here on the Camp.
