Get the MSDS! The MSDS sheets on the product will make recommendations on fire fighting materials.
Some of these are propylene glycol based, some are ethylene glycol based, they are mostly Class IIIB, water miscible, combustibles. If they are deicing runways there are a host of other components used for that. If they are only doing recovery and not purifying or reconstuting then you may be dealing with a diluted composition. There should be a whole lot more info from the Architect on the plans than what you describe. They should have had someone with special hazards fire protection experience set the criteria and define the basis for design. Depending on the composition of the product, some of these installations can require foam-water sprinkler systems. Get the MSDS! http://205.153.241.230/P2_Opportunity_Handbook/6_I_7.html Other issues that they may not have considered is containment of sprinkler discharge. If they've already specified a dike height, what did they base that on if the sprinkler system hasn't been designed yet? They've got to contain their largest vessel plus 20 minutes of sprinkler discharge. I'd ask what value they assumed for sprinkler discharge. Hopefully they know that most of this stuff can't be allowed into the ground or into public sewers and sized the containment area accordingly. The other questions is what kind of process requires a boiler? Are there other chemicals being used in some process? Questions, questions, questions.......................... Craig L.

Does Ordinary Hazard Group II seem right for protection? I don't have much info other than a floor plan that show dimensions, 4 tank storage with a 24" dike, lab, toilet, boiler room and what looks like a wash down area (has a trench), garage doors are 20' wide. Metal building with 60' peak. All info I have. Any insight or experience with this would be helpful. Bryan A.
