Ray, First in order to do any kind of analysis you need MSDS on ALL of the products to be stored, then you need to know what kind of conatiners, if they are racked or palletized, how high and how much. Do you have a rack or storage arrangement plan? I assume you already know the building construction characteristics?
Don't assume that NFPA 30 will be the only place to look. Flammables and combustible liquids will probably be the least of any commodity when it comes to pesticides. Mostly you'll be dealing with toxics and highly toxics which don't have a big impact on the fire protection systems in and of themselves but they do have major impact on other systems which could in turn affect your installation, such as ductwork (obstructions). Toxics are addressed in the Building Code as far as allowable quantities in reference to occupancy classifications. Most likely you will be dealing with an "H" Occupancy. You do need to consider combustible dust as one possibility, but again, that results in little change to sprinklers. Also know that for some items there maybe Federal and\or State guidelines (CFR) related to the storage and handling. But once again, for toxics there is little impact on fire protecton. All these issues SHOULD have been addressed by the EOR. On my designs I usually like to list the oddities if there is an area that is a bit out of the norm so that the contractor knows what drove the odd requirements. It helps clear up questions for him and also for the revewing AHJ down the road. The biggest impact that could result from a proper analysis would be changing the density based on plastic storage containers, in-racks versus none just as a few items. Also watch for pallet storage, wood and\or plastic. Plastic pallets pose an issue by themselves. What could have greater impact would be building construction for explosion relief and explosion resistant construction (keep this in mind when locating things like risers and standpipes, best to try and locate them away from the middle of a relief panel), HVAC, electrically classified components (this could impact you in relation to flows and tamper switches, etc.) Craig Prahl, CET 864-599-4102 ________________________________________ From: [EMAIL PROTECTED] [EMAIL PROTECTED] On Behalf Of Ray Vance [EMAIL PROTECTED] Sent: Thursday, October 16, 2008 11:29 AM To: [email protected] Subject: Pesticides Storage Esteemed Collegues: Can anyone give guidance on a Pesticides Storage warehouse and the approriate fire protection requirements? NFPA-434 doesn't give prescriptove requiremetns or a definitive path to follow. It only indicates a risk analysis be done by a "competent individual" (I read PE or FPE) to determine the extent and type of fire protection to be provide. Without regard to storage arrangement and heights, what TYPE of commodity would be appropriate to consider, since the amount stored is over 10,000 lbs and is extermely varied in the types and configurations of products to be stored? I am leaning towards NFPA-30 "Flammable and Combustible Liquids" to begin my analysis, but would like the opinions of anyone who has had experience with this process.
