Hello, my first post in here. My question is....just because a material or a product has a health rating of "1" according to NFPA 704, does that automatically mean that the product is corrosive? Battling with maximum allowable quantities for a product that IS NOT CORROSIVE. Thinking that the fire dept is not correctly interpreting the fire code. By the way this is the California Fire Code. Any thoughts?
Its actually a finished product. See link.
This is just one of the few that we are being restricted to 975 (liquid) gal per control area.
Looked at the MSDS.
pH is on the alkaline (base) side; considering how pH is measured & calculated for MSDS, the full concentration solution will have a higher pH number in the container. If the container is pH measured, it most likely will push into the caustic range. If either acid or base, the material is considered "corrosive" by definition.
Thank you for the replys, but I still dont understand why we are being held to the code book to limit the amount we can hold in a single area. Laundry detergent has a pH of something like 12 and I guarantee the fire dept doesnt limit supermarkets from holding more than a certain amount. Our product probably is less of a health risk then detergent. Still lost. Someone is interpreting the code wrong is my thought.
Could it be that your container is glass (which can't breath) but soap is cardboard (which can breath)?
Consider alternate means (storage vessel with a pressure relief valve, double walled vessel?)
This is a finished product in 2.5 gal jugs. 2 to a box and 36 boxes per pallet. 180 gal total. Im not sure the fire dept thinks about whether it can breathe or not. They are just going by the code and what someone told them in the past. To me it sounds more like depends on which inspector is handling your case. In our case they are holding up 20 jobs for a small community.
there is a large difference between high calcium fertilizer and common detergents. Calcium is vigorous in chemical reactions and creating hydroxides that are caustic, while detergents are generally stabilized to not be caustic.
If you think there is a case to be made for this calcium fertilizer being mistakenly categorized, then get a chemist skilled in determining the fire code ranking and classification to give you adequate info for the Fire Dept.
