Cleanroom Design

08/07/2007 11:14 AM

I would like to know if an 12' x12' x 8' room would require fire suppression, if so what type. Besides having two computers; the room will contain a robot arm, which will move small filters to be weighed on a microbalance. Those will be the only electrical components in the room. From what I know about the ISO spec, they say the requirement should meet the specifications of the local code. My question is more about if fire supression is usually recommended and something other that a fire extinguisher.

Zoning codes should answer you question, but common sense tells me yes it would need it. Commerical property even a school where student might be exposed to harm would require fire suppression. Better to be safe than sorry.

I would like to clarify the location. This clean room will be inside of a building (like a building within a building)that has a sprinkler system as its fire suppression.

I works for Seimens for a while and they had spriklers every where even janitors closets and storage closets where only anti magnetic clothing and tags were stored. Static was a big worry because of micro damage to parts and could start fires with some of the chemicals they used.

Call you local fire marshal they love to help.

To ask your local fire marshal is an excellent advise!

If you have electronics in the room, you probably will have to use an extinguisher filled with a substance that will do no damage these components.

HALON might be a good alternative!

Here we have a saying: "what does not get destroyed by fire will be destroyed by the fireman" so, prevention comes first!

Halon is not only obsolete but banned in many places, as it extinguishes people as well, and is hard on the ozone layer. Modern systems use inert gases and non-wetting liquids.

You see! That is why I suggested to contact the fire dept!!!!

I honestly didn´t know Halon is banned. About 20 years ago, when I owned a CT and RMI scanner, extinguishers with Halon were recommended to us by the guys who did the fire installation ...things have obviously changed! Good thing is we never had to use them!!!

I am not sure but I did reply to dadw5boys about contacting the fire department. I meant to comment on the thread. Thanks for your suggestions. I will also talk to them about the proper fill for the fire extinguisher. I am aware of the dangers of halon.

Thanks Everybody.

we commonly erected temporary cleanrooms. We had no need for overhead fire suppression in similar and larger structures in WA, VA, OR, MA, TX, AZ.

HOWEVER - you insurer and local authorities should be consulted. The materials used to build the cleanroom themselves might pose a problem to your fire policy, or the existing fire system.

YOU ABSOLUTELY MUST CHECK WITH POWERS THAT BE.

God forbid something happen and you be held liable.

I was trying to find who those powers would be. Our agency has contacted several municipal departments, and have yet to get any response. For some reason we never thought of the Fire Marshall or someone in the Fire Department until it was recommended here.

I have found quite often that this forum can be BOTH, informative and amusing.
