Shaping Smarter Regulations

Update Standard for Storage of Ammonium Nitrate

The Institute of Makers of Explosives (IME) supports the existing ammonium nitrate (AN) standard at 29 CFR 1910.109(i), but recommends that it be modified to include; (i) a prohibition on the use of wooden storage bins, (ii) an instruction that fires involving AN should not be fought (our recommendation against fighting AN fires is aimed at offsite first responders, not to trained, in-house fire brigades that respond to emergencies in accordance with facility emergency action plans), and (iii) a requirement that facilities prepare written emergency response plans and share these plans with the local emergency responder community.


These recommendations are included in IME’s Safety & Security Guidelines for Ammonium Nitrate (2014), endorsed by the International Association of Fire Chiefs; the National Stone, Sand & Gravel Association; and the International Society of Explosives Engineers. The recommendations are largely consistent with the National Fire Protection Association (NFPA) 400 standard that is currently being updated for 2016.
