Stick with the sprinklers - gas systems discharge due to spurious
sensor actuations, lightning and other stimuli. I know that it can be
difficult to source replacement gas supplies in the Kingdom and the
cost and delay could impair the lab's mission.
If you really are worried about sprinkler heads being hit by accident
then by all means consider recessed or institutional heads. If you
are really worried about spurious actuation of sprinklers go to a pre-
action system.
Don't worry about electrical issues - IBM sprinkle all their labs,
workshops and factories !

Newly constructed research and development lab facility is protected
by a wet type sprinkler system, one of the lab scientist is worried
about the accidental release of the automatic sprinkler heads on
top or in the vicinity of the high tech., expensive analytical
instruments such as NMR, FTMS, autospec GC/MS and ESEM , which
present a potential risk of damage to these instruments in case
these sprinklers kick off during actual emergency or broken by
mistake by a maintenance personnel or a lab personnel. He suggests
gas suppression instead. I explained to him that accidental leakage
of wet type sprinkler system is very minimal. The question is what
the probability of activation and how much will it cost to replace
the existing system with a gas suppression system. Your
recommendations/insights are highly appreciated.
