Appologies to Bobby, since he's getting this twice because I replied to him instead of the list: NFPA 33 may throw an additional wrench in this though, it applies to powder coating and does not make any distinction between overspray from that process and any other spray coating method. Common sense says powder coat is just charged plastic dust, but common sense doesn't prevent lawsuits. I think if it was my neck stuck out I'd replace the heads and cover the new ones per NFPA 33 2011 9.4.7 to 9.4.7.2. Mike Morey, SET, CFPS Sprinkler Designer BMW Constructors, Inc.

I understand this is a powder coating operation and not paint. Maybe the Fire Inspector believes the powder residue is removable in the same manner as the "dust" mentioned above; of course this is only possible if it didn't adhere. If it can be cleaned, as described in 25, then ok. If it cannot then I think changing them is in order and after they are changed overspray protection per NFPA 13 - 2013 6.2.6.4 needs to be applied to the sprinklers and maintained.

A.5.2.1.1.2(5) - In lieu of replacing sprinklers that are loaded with dust, it is permitted to clean sprinklers with compressed air or by a vacuum provided that the equipment does not touch the sprinkler. I have a situation where this is being interpreted to mean that sprinklers covered with residue from a powder coating operation are to be cleaned by order of the Fire Inspector. Also, who can we contact with the NFPA 25 that may have already or will address the intent of the above standard.
