[Nhcoll-l] Sprinklers in wet collections

[Bentley, Andrew Charles]

Hi Gali

I think the issue with water sprinklers spreading a fire are a little overblown personally.  Her at the University of Kansas, Biodiversity Institute we had a new facility for our wet collections built in the mid 90's and we went with a three pronged solution:


1.       Lowered temperature - 65°F - below the flash point of 70% ethanol which is 70°F

2.       HVAC system that replaces air every two hours in the facility to prevent vapor buildup, and

3.       A sprinkler system and smoke detectors.

Personally I think the potential hazard to people of any gas replacement system (CO2 or otherwise) and the additional cost (very expensive initially and to maintain) far outweighs any potential issue with a sprinkler system.  70% ethanol would be diluted so quickly that it would have very little chance to spread dramatically within a facility in the event of a fire.

Hope that helps

Andy

Subject: [Nhcoll-l] Sprinklers in wet collections

Dear Colleagues,

We are currently dealing with a proposal to install water sprinklers in our wet collection storage facilities as part of the general fire hazard measures. It will be very helpful to know what kind of fire-extinguishing measures have been installed in other facilities holding jars and containers with alcohol / formalin / other preservative fluids. Were there any particular considerations your institute took into accound, given that preservation fluids tend to be so flammable?

Many thanks for your thoughts on this subject,
