Gaseous Suppression
With the multiple Gaseous Suppression System choices for protecting high risks, consideration should be taken by the fire engineer on several factors which will aid the selection of a suitable agent during the risk analysis phase.




DIS Fire Systems engineers have had exposure to the world’s leading gaseous fire suppression system hardware manufacturers and as such can conduct a detailed risk analysis on the proposed system taking into consideration the following: –
- Suppression agent Extinguishing mechanism.
- Design concentrations and amount of extinguishing Agent needed.
- Safety for people.
- Cylinder locations and Pipe Distances to the risk area.
- Any Toxic by-products produced by the suppression agent.
- Suitability of the enclosure to maintain extinguishing agent retention.
- Suitability of the enclosure in regards to room over and under pressures produced during system discharge.
- Ozone Depletion Potential (ODP), Global Warming Potential (GWP) and Total Environmental Impact (TEWI).
- Suppression Agent holding time.
- Overall system lifetime Cost analysis.
DIS Fire Systems can offer a complete design, engineering and commissioning service on the following gaseous suppression systems:-
