3.2.3 Calcium Oxide — Powder
Calcium Oxide should be stored in a cool, dry place. It should be kept dry.
Calcium Oxide is considered to be stable. Water, acids, and other products with water of hydration (I.e.:
Zinc Sulfate) should be avoided. Contact with water produce heat.
3.2.4 Sodium Ethyl Xanthate — Powder
Sodium Ethyl Xanthate should be stored in dry, cool, and ventilated areas. It should be kept away from
sources of heat and ignitions. Remove from direct sunlight and isolate from acid. Ensure containers are
properly closed and protected against physical damage.
Sodium Ethyl Xanthate is considered to be relatively stable when dry. It can be spontaneously
combustible above 482 degrees F. It is hygroscopic and easily reacts with moisture. It is also
incompatible with acids. It absorbs moisture and reacts to form carbon disulfide, ethyl alcohol, sodium
carbonate and trithiocarbonate. It will generate heat at the same time and the heat accelerates
decomposition. Decomposition also occurs under condition of acid.
3.2.5 Potassium Amyl Xanthate — Powder
Potassium Amyl Xanthate should be stored in a dry, cool, ventilated place. It should be kept away from
heat, and moisture. It should be stored between 50 degrees and 90 degrees F. It should not be allowed
to age as aging, as well as heat and moisture can cause some decomposition.
Potassium Amyl Xanthate is considered to be stable. It begins to decompose above 267 degrees F and
can auto - ignite. It is incompatible with moisture, strong oxidizing agents, acidic material and high
temperatures. The storage containers should be kept closed when not in use. When it decomposes, it
produced carbon disulfide, carbon monoxide, carbon dioxide, oxides of sulfur and hydrogen sulfide.
3.2.6 Promoter Aero -3477 — Liquid
Aero -3477 should be stored in a cool, dry place. To maintain quality of the promoter, it should be stored
at room temperature, though freezing will not affect its activity.
Aero -3477 is considered to be stable. It flashes above 200 degrees F and decomposes on contact with
strong oxidizing agents and mineral acids. The decomposition produces carbon monoxide, carbon
dioxide, hydrogen sulfide, oxides of sulfur, and oxides of phosphorus.
3.2.7 Promoter Aerofloat -242 — Liquid
Aerofloat -242 should be stored in a cool, dry place. It should not be heated or exposed to heat above
175 degree F.
