Servicing of fire extinguishers includes performing which of the following?

Fire extinguisher servicing encompasses a comprehensive approach to ensure that extinguishers are functioning properly and ready for use. This includes maintenance, recharging, and hydrostatic testing.

Maintenance involves regular inspections and any necessary repairs to ensure the fire extinguisher is in good working condition. This can include checking the pressure gauge, verifying that the labels are intact, and ensuring that the nozzle is clear of obstructions.

Recharging is the process of restoring the fire extinguisher's active extinguishing agent after it has been discharged. This is critical for ensuring that the extinguisher will effectively combat a fire when needed.

Hydrostatic testing is a safety measure that involves testing the integrity of the extinguisher's cylinder to ensure it can withstand the pressure required for operation. This is typically performed at a set interval (every 5 or 12 years, depending on the type of extinguisher) to verify the structural integrity of the unit.

The inclusion of all three components—maintenance, recharging, and hydrostatic testing—in the servicing process is essential for compliance with NFPA standards and for ensuring safety in the event of a fire emergency.
