Dear Lisa We have 2 systems in our water-sensitive collection stores. The first protection that will be triggered in the event of a fire is the inergent gas system (equivalent of the dry pipe system i believe?). Above 60 degrees celsius or so would the water sprinkler system be triggered as an added layer of protection. I am not sure if this is the best appraoch really. There has been some controversy (even in our org) on why we even need a water sprinkler sys as a second layer protection when the inert gas system should by right suffice. for your info, it is not until recently that they revise the statutory requirement that all buildings should have water sprinklers. I supposed nothing can be conclusive. Just to answer your question, people have to evacuate the room immediately when the inergent gas alarm sound and close the door behind them to contain the gas. Thus the sys is only suitable for installation in 'enclosable' space for it to work and for human safety. Hope this helps a little.

My understanding from previous discussions is that dry-pipe systems are preferred? Our board members are insisting there must be a good gas fire suppression system, but I am not familiar with any that are OK for use with people in the room. What is the general consensus? I printed the technical leaflet from the NDCC which is very helpful, but would appreciate any personal experiences. Thanks very much. Lisa Moellering, C.A.
