1. Re-stamping and pressure testing (Quinquennial Tests)

Hydrostatic testing: This is the main task. It involves introducing water at high pressure into the fire extinguisher body or gas cylinder (normally at 1.43 times its service pressure, with a minimum of 20 bar) to verify that the metal has no micro-cracks, deformations, or corrosion and is 100% safe.

Legal compliance: Certifying that extinguishers pass this mandatory test, which is carried out every 5 years (with a maximum useful life of the equipment of 20 years).

1. Recharging and pressurizing equipment

Charging extinguishing agents: Emptying, cleaning, and refilling extinguishers with their corresponding agent (ABC dry chemical powder, water with additives, or CO2).

Pressurization: Introducing the propellant gas (generally dry nitrogen) at the exact working pressure so that the pressure gauge sits perfectly in the green operational zone.

1. Maintenance and replacement of pressure components

Disassembling, cleaning, and thoroughly inspecting valves, hoses, diffusers, and pressure gauges.

Replacing worn sealing gaskets and O-rings to prevent pressure micro-leaks throughout the year.

1. Maintenance of fixed systems and pressure booster sets (depending on specialization)

If the technician works in the field (customer installations) as well as in the workshop, they are responsible for checking the water pressure booster sets that feed the FHCs (Fire Hydrant Cabinets) and the sprinkler systems, ensuring that the pumps start at the programmed pressure and maintain the required flow rate.

Inspecting fixed gas extinguishing systems (such as in server rooms), checking the weight, condition, and pressure of the inert or chemical gas cylinders.

1. Completing reports and labeling

Affixing the mandatory maintenance labels and inspection tags detailing the date of the pressure test and its expiry.

Digitally recording the work carried out to issue official reports in accordance with the UNE 23580 standard, ensuring traceability for inspections or insurance company audits.
