A safety button to shut the fire suppression system off before entering the room where the FM200 tanks are stored? I don't see a need for something like that.But for safety issue, do we need outside safety button?
I think we need more clarification on this. I was under the impression that the tanks were being stored in this room for a separately protected area and not that the room was the area or equipment being protected. If the latter is the case why would someone design a system where the release of the suppression agent will corrode the equipment it is looking to protect ?FM200 isR-227ea ( I believe ) and when the decomposition
temperature is reached, HF gas is is a byproduct. HF in the presence
of moisture ( H2O ) will form Hydrofluoric Acid. So if permitted
it would be good to be stop the system if there is any one in
the room. The HF acid may be far worse threat than a mild
electrical burn. SO it needs to be done on a risk based
analysis. For example, are the doors to the room gas tight
( or at least semi-gas tight ) I don't know but an R-227ea
fire suppression system may stop the fire, but hydrofluoric
acid can and will dissolve glass, concrete and practically
everything else in the room (of electrical importance)
If the room is gas tight I suppose it would protect the rest
of the building, but your switchgear/panels will be sacrificed
in the activation of this system.
