System maintenance
automatic gas extinguishing systems (IEAG)
An automatic gas extinguishing system is a fixed system that detects and inhibits the outbreak of a fire at an early stage, using neutral or inhibiting gases. These systems are recommended for the protection of strategic company premises, particularly those containing valuable equipment, or those which could jeopardize operations in the event of downtime. Maintenance and periodic inspections of these systems are mandatory to ensure their longevity and proper operation.

Regulations
APSAD rule R13 lays down strict guidelines for the maintenance of automatic gas extinguishing systems. It recommends regular checks on detectors, control units and sprinklers.
Technicians must check the integrity of gas tanks and the pressure of extinguishing agents. A leak test of the protected area is essential to guarantee the system's effectiveness.
The standard also requires :
- A thorough examination of valves and piping
- Checking that alarms are working properly
- Controlling timers and safety devices
These rigorous procedures are designed to ensure optimum reliability of IEAGs in the event of a trip.
The frequency of IEAG checks varies according to the system components. Weekly checks include visual inspection of pressure gauges and status indicators. Monthly checks include alarm testing and seal verification.
Every six months, a qualified technician carries out a thorough inspection of the detectors, manual releases and diffusers. The annual examination includes :
- The complete detection system test
- Checking the tightness of the protected area
- Analysis of extinguishing agent concentration and quality
A customized maintenance plan takes into account the specific features of each installation, ensuring optimum, ongoing protection against fire hazards.
