Class K fires are fires in cooking oils and greases such as animal fats and
vegetable fats.
Some types of fire extinguishing agents can be used on more than one class
of fire. Others have warnings where it would be dangerous for the operator to use a
particular fire extinguishing agent.
If you decide not to fight the fire, try to close the door to the fire area, if it is
safe to do so. This will help to prevent heat, smoke and toxic gases from entering
the egress corridors. Then evacuate the building via the closest exit.
A periodic check of the extinguishers should be performed to ensure:
a) the extinguisher is not being used inappropriately (for example, to prop a
door open);
b) the extinguisher pressure gauge needle is in the green zone;
c) there are no visible indications that the extinguisher has been damaged,
discharged, or removed from its proper location;
d) that the inspection tag is attached to the fire extinguisher. The inspection
tag must be stamped with a month and year indicating the extinguisher was
inspected within the past twelve months.
