B) Operations to be carried out by specialised personnel from the manufacturing firm or installer:
Every year:
- Verify the load status and, in the case of dry chemical extinguishers with an attached propellant cartridge, the status of the extinguishing agent.
- Check the propellant pressure of the extinguishing agent.
- State of the hose, nozzle or lance, valves and mechanical parts.
Every 5 years:
- The manufacturer or distributor is to re-date stamp the extinguisher (three times) from the original date-stamping of the extinguisher.
