Those system probably will blow the room apart based on the description of the lightweight materials used to create the rooms.

Mario Berrios [email protected] -----Original Message----- From: Russell & Carol Gregory <[email protected]> To: sprinklerforum <[email protected]> Sent: Sat, Aug 29, 2015 12:04 am Subject: RE: Clean room sprinklers The basic answer is that it should be protected. We try to control a fire at its earliest stage of development. It is unreasonable to wait until an ESFR head at the roof operates when this room and its contents will probably have been destroyed. The water damage may be excessive. The smoke will have spread around and coated stored material in adjacent racks. Equate cost to install against damage caused. There are a number of unknowns; Value of room and contents? Type of goods stored in adjacent racks? Is room moved regularly as you said it was portable or is it temporary? Can it be sited adjacent to a wall or end of rack so a dropper can be run down to the 2 - 4 sprinklers needed?

The room itself has plastic sheeting for walls and the ceiling is composed of air vents and acrylic panels. No storage of combustibles is allowed inside and they use it to check LED panels for defects. The room is about 12X20. Is there any exception in NFPA 13 that would allow the omission of sprinklers from the room? It just seems silly to require sprinklers in the room when you have 30ft rack storage next to it protected by the ESFR system.
