Understanding Fire Classifications and Foam Solutions in Firefighting

This article explores the various classifications of fires as defined by the NFPA, with 97% of all fires categorized as Class A, which includes wood, plastic, and rubber. It also discusses other classes like Class B (flammable liquids and gases), Class C (energized electrical), and Class D (flammable metals). Additionally, we delve into foam solutions used in firefighting, including the process of creating finished foam from a foam solution, and the importance of the critical application rate for effectively extinguishing fires.

  1. Definitions

  2. Per NFPA statistics, 97% of all fires fall into the Class A category Fuel Classifications • Class A • Wood, plastic and rubber • Class B • Flammable liquids and gas • Class C • Energized electrical • Class D • Flammable metals

  3. Foam Solution • Water + Foam Concentrate = Foam Solution

  4. Finished Foam • Foam Solution + Air + Agitation = Finished Foam

  5. Compressed Air Foam SystemsCAFS • Foam solution + air injected under pressure • A foam delivery system that incorporates • A water pump • A foam proportioner • An air compressor

  6. Critical Application Rate • The flow rate (water or solution) applied to a fire at which the fire does not grow • Exceed the critical application rate and the fire is extinguished • Flow less than the critical application rate and the fire burns unchecked
