Fire Extinguisher Rating System
Fire extinguishers are rated using a system of letters and numbers:
CLASS A
Designed for use on combustible solid materials such as wood and paper
CLASS B
Designed for use on combustible liquid fires including gas, oil and grease
CLASS C
Designed for use on electrical fires
The number identifies the amount of agent (material that puts out the fire) that is inside the extinguisher. The higher the number, the greater the amount of fire-fighting agent in the device. For example, a Class 3 extinguisher can extinguish a larger fire than a Class 2 extinguisher.
The Small Vessel Regulations require that Class BC extinguishers be used on boats in Canada. However, the use of a Class ABC fire extinguisher is recommended. Ensure that the fire extinguisher you choose meets the requirements for the size and type of your boat. Remember, even if your boat is equipped with an automatic extinguishing system, you still must carry portable fire extinguishers.
