What is an essential step in fire extinguisher maintenance?

An essential step in fire extinguisher maintenance is checking the pressure gauge readings. The pressure gauge indicates whether the fire extinguisher is properly charged and ready for use. A reading in the green zone signifies that the extinguisher is adequately pressurized, which is crucial for effective operation in case of a fire. If the gauge shows a low reading or is in the red zone, this indicates that the extinguisher may not function correctly and requires servicing or recharging.

Regularly checking the pressure gauge helps ensure that extinguishers are always ready when needed, as they may not be used frequently but must perform effectively in an emergency. This step is a vital part of compliance with safety regulations and standards, ensuring that fire extinguishers maintain their functionality over time.
