Hazards and Protection.
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.
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.
Wear appropriate protective gloves, clothing and goggles.
Wear positive pressure self-contained breathing apparatus (SCBA).
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.
Mixtures with ammonium salts, powdered metals, silicon, sulfur, or sulfides are readily ignited and potentially explosive.
When heated to decomposition it emits toxic fumes of hydrogen chloride.
Flood with water. Cool all affected containers with flooding quantities of water. Apply water from as far a distance as possible.
Forms explosive mixtures with combustible, organic or other easily oxidizable materials.
When involved in a fire, may cause an explosion. Irritating gases may be generated when heated.
Not combustible, but if involved in a fire decomposes to produce calcium oxides and toxic gases.
Blood pressure may be decreased. Pulse may be irregular. Lethargy, coma, and seizures have been reported.
Nausea, vomiting, diarrhea and abdominal pain may be a common occurrence early in chlorate toxicity.
Severe hypoxia with cyanosis, resistant to oxygen therapy, may be noted within several hours following exposure.
Pallor may be noted.
Induce vomiting and get medical attention.
Remove to fresh air.
Flush with water.
Flush with water for 15 min.
