Class B fires involve flammable liquids and gases, including chemicals and grease.
Types of fire extinguishers used to extinguish a class B fire:
- General purpose, pressurized dry chemical ABC extinguisher
- BC pressurized dry chemical extinguisher
- Carbon dioxide (CO2) extinguisher
- NEVER use water on a class B fire since this will only increase the hazard.
- Class B fires can flash back and reignite after being extinguished.
