Carrying Out an Audit on Fire Extinguishers at School

• Identify the types of fire extinguishers found in the school.
• Check the labels on each fire extinguisher. The expiry date of the fire extinguisher
is displayed on the label.
• Ensure that the needle of the pressure gauge is in the green zone. If the needle
is deviated to the red zone on the left, then the pressure has reduced whereas
the needle that is deviated to the red zone on the right shows that there is
excessive pressure in the fire extinguisher.
• Record the number of fire extinguishers found in your school according to their
types.
• Ensure that the fire extinguishers are placed in the correct locations according
to the school emergency evacuation plan. Make sure that there are no other
objects obstructing the path to a fire extinguisher making it difficult for anyone
to access it in the event of an emergency.
