Hazards and Protection.
Keep in a cool, dry, dark location in a tightly sealed container or cylinder. Keep away from incompatible materials, ignition sources and untrained individuals. Secure and label area. Protect containers/cylinders from physical damage.
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. Remove trapped material with suction hoses.
Mixtures with ammonium salts, powdered metals, silicon, sulfur, or sulfides are readily ignited and potentially explosive.
Flood with water. Cool all affected containers with flooding quantities of water. Apply water from as far a distance as possible.
Cloth, leather, wood and paper are extremely flammable when impregnated by chlorates. Chlorates mixtures of finely divided combustible materials (such as certain dusty forms of floor sweeping) with chlorates can ignite virtually spontaneously.
May explode from heat or contamination.
Yields toxic fumes when involved in fire.
TLV (as Ba): ppm; 0.5 mg/m3 (as TWA) (ACGIH 1991-1992).
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.
Mydriasis may be present early in the course.
The possible benefit of early removal of some ingested material by cautious gastric lavage must be weighed against potential complications of bleeding or perforation. Activated charcoal activated charcoal binds most toxic agents and can decrease their systemic absorption if administered soon after ingestion. Activated charcoal: administer charcoal as a slurry (240 ml water/30 g charcoal). Usual dose: 25 to 100 g in adults/adolescents.
Remove to fresh air.
Flush with water.
Flush with copious quantities of water for at least 15 min.; get medical attention.
