What is the fire extinguishing density (liters/minute/m2) which is required by NFPA 13 to deal with ammonium nitrate storage?
The NFPA 400 specifies that the ammonium nitrate belongs to the minimum extra hazard Group 1 .
Extra hazard Group 1 requires a density of at least 12.2 mm/min in 232 m².
Thanks for your answer ‘extra hazard Group 1 requires a density of at least 12.2 mm/min in 232 m².coul you specify in which chapter of the NFPA did you find this information? thanks in advance Regards, Laurent

See section 11.2.3 of NFPA 13 (2016).
Always more to add.
Design and installation must also include the provisions in Section 18.104.22.168 of NFPA 13 for General Requirements of Ammonium Nitrates Solid and Liquids for the designated commodity classification.
Thanks you for your answer ,nevertheless , in this chapter , I was not able to find the corresponding extinguishing density.
In which chapter can I find it ? thanks in advance laurent
