If you have lay-up areas where they are spraying fiberglas, with low heads, 
they can get a lot of residue on them.  Also if there is a sanding/finishing 
area the dust can cake on sprinklers as well if they don't have booths and 
adequate ventilation.

These operations can be real messy and the overhead sprinklers really need to 
be inspected and maintained more often than in typical manufacturing areas just 
due to the airborne residue.

I’d also be concerned with heads being loaded. Slow, but hard to observe.

Maybe in a modern plant with adequate exhaust this isn’t a problem.

EH2.

Best.
