For storage, disposal, etc., see Calcium Chloride, C0018.
CAS No. 10043-52-4
Technical Note: An effective drying agent for desiccators and drying tubes.
Calcium Chloride
for drying, also see Drierite®—a special form of calcium sulfate that absorbs both by hydration and capillary action.
 HAZARD ALERT: Exposure to water or moisture evolves flamma- ble acetylene gas; corrosive to eyes and skin. 500 grams of calcium carbide will yield approximately 150 liters of flammable acetylene. Storage: Inorganic #5 in a Flinn Saf-Stor TM Can.
Disposal: #25
Shelf Life: Good if stored under dry conditions.
Soluble: Decomposes in water.
Color and Odor: Gray/black solid with garliclike odor.
CAS No. 75-20-7
Incompatibility: Water, dilute acids, halogens, silver nitrate, copper compounds, and heavy metals.

Heavy Metals
Heavy metals, including cadmium and cadmium compounds, are most dangerous if inhaled as a fume or fine dust. Water soluble compounds of heavy metals are also toxic, but inhalation and ingestion are extremely unlikely. If the cadmium you intend to use will not generate a dust that can be inhaled, prudent prac- tice suggests that it is not necessary to ban the material. Many heavy metals serve useful purposes in everyday life. Know the substance, how it can hurt you and how it can be properly disposed of. Don’t be chemophobic!
