Hazards and Protection.
Storage
Store in a cool, dry, well ventilated location. Separate from acids, alkalies, reducing agents, combustibles, sulfur compounds. Do not store on a wooden floor. Calcium chlorate dihydrate keep well closed.
Handling
All chemicals should be considered hazardous. Avoid direct physical contact. Use appropriate, approved safety equipment. Untrained individuals should not handle this chemical or its container. Handling should occur in a chemical fume hood.
Protection
Wear appropriate protective gloves, clothing and goggles.
Respirators
Wear positive pressure self-contained breathing apparatus (SCBA).
Small spills/leaks
Keep sparks, flames, and other sources of ignition away. Keep material out of water sources and sewers. Land spill: Dig a pit, pond, lagoon, holding area to contain liquid or solid material. Cover solids with a plastic sheet to prevent dissolving in rain or fire fighting water. Dike surface flow using soil, sand bags, foamed polyurethane, or foamed concrete. Water spill: Use natural barriers or oil spill control booms to limit spill travel. Use natural deep water pockets, excavated lagoons, or sand bag barriers to trap material at bottom. Remove trapped material with suction hoses.
Stability
No data.
Incompatibilities
Mixtures with ammonium salts, powdered metals, silicon, sulfur, or sulfides are readily ignited and potentially explosive.
Decomposition
When heated to decomposition it emits toxic fumes of hydrogen chloride.

Fire.
Fire fighting
Flood with water. Cool all affected containers with flooding quantities of water. Apply water from as far a distance as possible.
Fire potential
Forms explosive mixtures with combustible, organic or other easily oxidizable materials.
Hazards
When involved in a fire, may cause an explosion. Irritating gases may be generated when heated.
Combustion products
Not combustible, but if involved in a fire decomposes to produce calcium oxides and toxic gases.
