Nitrates-Continued Ammonium nitrate mixed fertilizer (containing over 13% but less than 60% by weight of ammonium nitrate). No permit required, see 146.22-30 (d). Ammonium nitrate mixed fertilizer meeting the following conditions are not subject to regulation: 1. The ammonium nitrate content is not over 13 percent by weight. 2. The mixture is nonacidic. 3. No other oxidizing material is contained in the mixture. 4. Less than 5 percent of organic or combustible is contained in the mixture. NOTE: Mixed fertilizers which fail to meet the above conditions but after testing in accordance with section 146.2230 (e) do not qualify as an inflammable solid, oxidizing material or 8 hazardous article are not subject to regulation. Mixed fertilizers not specified by name in this section. Includes ammonium nitrate phosphate and ammonium nitrate phosphate fertilizers containing less than 60% ammonium nitrate with no organic fillers. Mixtures of ammonium nitrate, and often other nitrogen compounds, with either or both phosphate and potash compounds. Mixture must be treated to make whole mass nonacidic in nature. Acidic mixtures attack fabric or paper containers, and tend to heat spontaneously. Must contain less than 5% of organic or combustible ma terial. Containers shall be marked with the percent by weight of ammonium nitrate contained in the mixture. Do not accept for shipment if the temperature of the material exceeds 130° F. Do not stow in the same hold, nor in any hold above or below one in which explosives are stowed. The engine and boiler spaces or one complete hold shall intervene between stowages on a horizontal plane. com Do not stow in the same hold, nor in any hold above, below, or adjacent to one in which inflammable pressed gases (red gas label), inflammable liquids (red label), combustible liquids, or corrosive liquids (white label) are stowed. Stow well away from steam pipes, electrical circuits, or other sources of heat. Use minimum of combustible dunnage. (See § 146.22-30 (1).) Remove trash, scrap, and spilled material promptly. Bags must be stowed so as to provide maximum ventilation and access for water in the event of fire. (See § 146.22-30 (1).) Containers shall be marked "Ammonium nitrate mixed fertilizer." In Event of Fire in This Cargo: Flood with large volume of water. Do not use steam or other methods of smothering. Provide maximum ventilation by removing hatch covers, and opening all access openings to the hold. Yellow.. Stowage: "On deck protected." Outside containers: Metal barrels or drums. Multi-ply paper bags, not over 200 lb. net wt., moisture proof, made tight against sifting and of a strength not less than bags made of 71⁄2 ounce burlap. Burlap bags, not over 200 lb. net wt., moisture proof, made tight against sifting, and of not less than 71⁄2 ounce burlap. NOTE 1: Ammonium nitrate mixed fertilizers containing over 13 percent by weight of ammonium nitrate packaged in metal barrels or drums, wooden barrels or kegs or fiber drums are exempt from the labeling requirement. NOTE 2: It is not required that he above containers be ICC specification containers, although ICO specification containers are acceptable, but the officer in charge of loading the vessel shall satisfy himself they are sufficient in all respects for the purpose intended. He shall refuse any containers showing damage, leakage, or inability to properly contain the substance.
