146.22-30 (d).

The mixtures are composed of Yellow..

approximately 60 percent by weight of ammonium nitrate and 40 percent of fine carbonate (precipitated calcium car. bonate, chalk, ground limestone, or ground dolomite). These should be blended to together by wet methods 80 that the proportions of the component materials are uniform throughout the mass. Contains approximately 20.5

percent by weight of nitrogen. 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 en. gine and boiler spaces or one complete hold shall intervene between stowages, on

a horizontal plane. Do not stowin the same hold, nor in any hold above, below, or adjacent to one in which inflammable compressed 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. Do not use explosives to break

up caked material. Use minimum of combustible

dunnage. (See (146.22-30

(f)). 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 itrate-Car

bonate mixtures”.

NOTE 2: It is not required that the above containers be ICO 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.
