Extinction automatique
par gaz
Aussi appelée IEAG, l’extinction automatique par gaz permet d’éteindre un départ d’incendie. Ce mode d’extinction est particulièrement efficace pour protéger des équipements informatiques, des installations électriques et des objets de haute valeur, sans les endommager.
Protect without damaging with automatic gas extinguishing
Control a fire before it spread
Gas extinguishing is one of the automatic extinguishing solutions for fighting a fire. Combined with early detection, the aim of gas diffusion is to extinguish a smouldering or open fire. The IEAG can use three types of gas, which do not act in the same way on the fire.
Inert gase
Inert gases reduce oxygen levels to smother the fire. This solution requires the room to be protected to be well sealed. Examples of inert gases: nitrogen, argon and inert gas mixtures.
Inhibitor gase
Inhibiting gases act by chemical reaction, counteracting the mechanisms that produce the flame. This solution requires the premises to be protected to be very well sealed. Inhibitor gas cylinders take up less space than inert gases. Examples of inhibitor gases: heptafluoropropane (HFC 227 ea), trifluoromethane (HFC 23) and perfluorobutane (FC 3-1-10).
CO2 ga
CO2 gas, like inert gases, works by reducing the oxygen level to smother the fire. This solution is perfect for processes where the room or object to be protected cannot be sealed.
Gas is safe for people and the environmen
With the exception of CO2, which is reserved for specific applications due to its toxicity, the gases emitted are not dangerous either to humans, provided that the required oxygen concentration in the air is respected, or to the environment.
It is necessary to evacuate people from the premises in the event of high concentrations or the use of inhibiting gases (risk of dangerous decomposition products).

The earlier a fire is detected, the faster and more effectively it can be extinguished automatically. This solution intervenes before the destructive flames arrive. It causes little or no damage. The return to activity can then be faster.
The automatic gas extinguishing systems are connected to the building’s fire detection system (SDI). As soon as this system receives an alarm from the detectors, it automatically activates the emergency procedure via the DECT: alarm, evacuation of people, compartmentalisation and opening of valves to diffuse the extinguishing agent.
The gas is distributed to the area concerned, either from tanks located in the room (modular installation), or from a dedicated room grouping the tanks together via a pipe network (centralised installation).

Protégez vos équipements du feu sans dommage
Plus la détection de l’incendie est précoce, plus son extinction automatique est rapide et efficace. Cette solution intervient ainsi avant l’arrivée des flammes destructrices. Elle ne cause pas ou cause peu de dommages. Le retour à l’activité peut alors être plus rapide.
Les systèmes d’extinction automatique à gaz sont reliés au système de détection incendie (SDI) du bâtiment. Dès que ce dernier reçoit une alarme de la part des détecteurs, il active automatiquement la procédure d’urgence via le Dispositif Électrique de Commande et de Temporisation (DECT) : alarme, évacuation des personnes, compartimentage et ouverture des vannes pour diffuser l’agent extincteur.
Le gaz est diffusé dans la zone concernée, soit à partir de réservoirs implantés dans le local (installation modulaire), soit depuis un local dédié regroupant les réservoirs via un réseau de tuyauterie (installation centralisée).
When should gas extinguishing
be used?
This technology is perfectly suited to clean extinguishing, with no residue or deposits. It is particularly suitable for premises with few occupants, areas requiring non-electrically conductive extinguishing agents and rooms containing valuable equipment or for which water cannot be used.
or where water cannot be used. APSAD rule R13 defines the limits for the use of gaseous extinguishing agents.
On retrouve principalement des IEAG dans les lieux suivants :
- Storage rooms containing flammable liquids, paint shops and laboratories
- Electrical and electronic installations such as telecommunications systems, computer rooms and data centres
- Museums, libraries and archives
- Ships and submarines
Legal standards and obligation
The IEAGs are subject to various legislative texts at European and national level:
- The French Labour Code
- European standard EN 15004
- A2P EAG system” certification guarantees that components comply with the relevant European directives, that they are compatible with each other and that the system performs well.
- The APSAD R13 standard defines French requirements in terms of the design, construction and maintenance of EAGS.
The stages involved in fitting a gas extinguishing system
The project for a gas extinguishing system involves a number of stages, from studying the file to maintaining the system. A smoke-extinguishing system requires a number of stages, from studying the project to maintaining the installations.
Feasibility studies and quotation
- Identification of the premises, issues, regulations and problems specific to the company. Proposal of a solution best suited to the situation.
Installation and verification
- Installation and commissioning of the system on the premises. Checking that the equipment complies with the latest regulations (European standard EN 15004 and APSAD rule R13)
Maintenance
- Two inspections a year are compulsory. The inspection must be carried out by a company with APSAD IF13 certification, which also checks whether any changes to the premises (watertightness) or risks (suitability for the gas used) could compromise the compliance or efficiency of the installations.Every 10 years, the system must be brought back into full compliance with updated regulations.
