Building insurence and painting8/31
Got an insurance inspection and they called me out on having some lights not explosion proof and some fans the same .Also not having a " flammable paint " storage cabinet. we don't have a spray booth with filters/ fans /lights but have a 60' x50' spray room with large intake and exhaust fans . Fire department inspections have always said I was OK on the big room and exahaust fans .Does insurance care about filtration or just explosion proof fixtures? anyone else paint like I do? any experience with insurance requirements? Thanks for any input
You can always buy your insurance somewhere else. Light switches and outlets would be the major consideration in my opinion. Sparking is the issue, and lights don't do that. Some will of course if the fixture is broken. When you expose the entire room to vapors, you'll have more trouble meeting spec. It better big one big ass fan to move enough air while spraying in a room that size!
Thanks Rich we are actually buying with new company this time around but have always had an inspection thru the years after having to move to new companys so Im trying to get ahead of it this time and have some things sited by previous inspector taken care of. In thirty years ive had several cancelations due to things unrelated to painting( in a 100 year old buiding ) but last years inspector harped on paint issues. Yes they are big exhaust fans about 36" x36" mounted to outside wall then also smaller ones sucking/blowing from intake side of room quit the draft in the winter
I know my insurance company required me to meet the NFPA33 regulations (as does the building inspector/ fire department). It may vary area to area but I would be really suprised if anyone would insure me if I wasn't up to code. I know explosion proof fixtures/ motors within a certain distance of the spray area are part of the code. You may be different because you are a spray room, not a booth.
the national codes are much different for a spray room vs a spray booth.
if you are classified as a spray room and you have a skilled inspector everything in the room must be explosion proof from the filled and sealed conduit to the connections to the electrical outlets, if this is enforced it is going to cost a small fortune especially if you go with fluorescent light fixtures at about 2k for a four tube, if you go incandescent you get a yellow tinge to your light for the exhaust fans you can mount them outside in fact fans are better at sucking air than pushing it unless you use a vane axial fan. so if you mount the fan and motors outside you could go with a tefc motor vs an xp motor.
the issue you might have is that at end the code it says "subject to the person who has local authority" which can be good in bad.
if he or she knows the rules of a spray room vs a spray booth and your insurance company is in the know, it could be a very expensive journey
as far as filtration, especially if you are spraying wood coatings, what you end up with is a dust rather than a sticky overspray, but coating dependant ie a urethane etc. most of the time i use f glass rolls and then periodically clean out the exhaust chamber with the dry overspray, but have been toying around with a polyester medial that would do a better capture on the fine dust particles. either way, i do suggest an air assisted airless system to minimiz eht the crap that goes into the filters, the a lot of the vapors just go out the stack
My insurance company didn't care where I was spraying or whether I had a real booth or an exhaust fan.
