John, I cannot speak to NFPA requirements on flammable liquid use in chemic
al fume hoods, but...

I can say that NFPA Codes/Standards do indicate sprinklers in gas cabinets 
+ exhaust ducting for pyrophoric gas use and/or semiconductor research / ma
nufacturing.  See NFPA 45 and NFPA 318, respectively.  I also see mention o
f sprinklers in paint booths and associated exhaust systems.  Perhaps the i
nsurer views the hoods you mention as analogous to paint booth operations? 
 Alternatively, if these hoods are more storage than operations, then the a
nalogy is drawn to inside liquid storage room per NFPA 30.

Whatever the case, I'd ask the insurer to cite you chapter and verse for re
commendations for upgrades.

All the best,

We use a water-mist system in our larger hoods (floor-mounted and scale-up)
.  The system was provided by Marioff, now part of United Technologies Corp
 (UTC) (  The advantages are that it minimizes damag
e to equipment (including electronics) in the hoods, minimizes smoke damage
, and extinguishes the fire very quickly.  It is more effective than regula
r sprinklers at extinguishing flammable and combustible liquid fires.  The 
chemists accept it because the total volume of water is small and there isn
't water raining down on their equipment and chemicals.

While on the topic of sprinkler systems, what is everyone's view on
sprinkler systems installed inside a fume hood?  This has been a topic that
our insurer has batted around with us for years.  They would like to
recommend sprinklers be installed inside fume hoods where larger volumes of
flammable solvents are used (such as floor-to-ceiling fume hoods in our
scale-up labs and waste accumulation rooms).

Any comments would be appreciated.

We use these folks for our entire plant.  I'm not sure if Knoxville is in
his territory, but I'm sure he would send you in the right direction.

I would also recommend these folks; again I'm not sure if Knoxville is in
her area, but I'm sure she'd make a referal.

Either way, I'd check with your facilities folks to see which vendors are
used in other parts of the university.  You might get better service this
way and it's definitely easier to work with only one vendor.  If they don't
have someone they recommend, you want to make sure you find a vendor that
understand the safety needs of a laboratory.

Contact a local sprinkler design and engineering or fire engineering
consultant in addition to your insurer.

The University of Tennessee, Knoxville is renovating three biology labs
to be used Wet Chemistry Research Labs. Any recommendations for a
sprinkler system in the new labs ?  Thanks.    Al Hazari
