I have done outdoor systems in pipe racks etc... at refineries along the Texas coast (hurricanes). The electrical devices had to be EP. The valves were cast steel epoxy lined but that was probably because of the water supply.
At the copper mine the specialty materials were already purchased. We furnished the pipe and did the install. There shouldn't be a problem if the electrical equipment has the proper NEMA rating.

When you're in an area subject to hurricanes and you're protecting flammable liquid operations and storage, is it still ok to just let all the equipment sit out in the yard? Ron, when you ordered equipment, did you order anything special for the outdoor application or just off the shelf items? Craig L.

I hope there isn't there is a standard that requires an enclosure. We recently installed some systems at a copper mine with the AFFF tanks, risers and other stuff outside. It is pretty easy to build a rack from Unistrut and plywood to mount panels etc... One drawback might be the shelf life of the AFFF concentrate but that can be monitored with regular testing.

I have a situation where the "powers that be" want to just locate the fire risers, foam tanks, control panels and all assorted trim and accessories for two FP systems outside, exposed to the elements. The environment is a chemical plant in the SE. Freezing is not an issue and it's on private property not accessible to the public. The one hazard is a multi-level process structure w/ multiple deluge systems, the other is fuel storage tanks with the foam protection. I've given some verbiage from NFPA 13 concerning protection of equipment but since someone who did the initial write-up forgot the houses, the owner believes they are not needed. Any specific code requirements? Their idea is to order "weather proof" equipment. I guess they're going to hang the control panels by helium balloons. Craig L.
