Cal. Code Regs. tit. 8, § 5363
(d) Due to the corrosive and reactive properties of ammonium nitrate, and to avoid contamination, galvanized iron, copper, lead and zinc shall not be used in bin construction unless suitably protected. Aluminum bins, and wooden bins protected against impregnation by ammonium nitrate, are permissible.
Note: Steel or wood can be protected by special coatings such as sodium silicate (water glass), or epoxy coatings, or polyvinyl chloride coatings.
(h) Height or depth of piles shall be limited by the pressure-setting (caking) tendency of the product. However, in no case shall the ammonium nitrate be piled higher at any point than 36 inches below the roof or supporting and spreader beams overhead.
Note: Pressure-setting (caking) is a factor affected by humidity and temperature in the storage space and by pellet quality. Temperature cycles through 90° F. and high atmospheric humidity are undesirable for storage in depth.
(i) Ammonium nitrate shall not be accepted for storage when the temperature of the product exceeds 130° F.
Exception: Manufacturing or processing.
