Hazards and Protection.
Storage
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.
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 chemical protective gloves, boots 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.
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. Decomposes at 120 C with evolution of oxygen.

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
Strontium chlorate. Is a powerful oxidizing agent and dangerous fire hazard. They are particularly sensitive to friction and shock.
Hazards
May explode from friction, heat or contamination. May ignite combustibles (wood, paper, oil, clothing, etc.). Some will react explosively with hydrocarbons (fuels). Containers may explode when heated. Runoff may create fire or explosion hazard.
Combustion products
Fire may produce irritating and/or toxic gases.

Health.
Exposure effects
Blood pressure may be decreased. Pulse may be irregular. Lethargy, coma, and seizures have been reported.
   Ingestion
Nausea, vomiting, diarrhea and abdominal pain may be a common occurrence early in chlorate toxicity.
   Inhalation
Severe hypoxia with cyanosis, resistant to oxygen therapy, may be noted within several hours following exposure.
   Skin
Pallor may be noted.
   Eyes
See Inhalation.

First aid
 
   Ingestion
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.
   Inhalation
Move victim to fresh air. Apply artificial respiration if victim is not breathing. Administer oxygen if breathing is difficult.
   Skin
Remove contaminated clothing and wash exposed area thoroughly with soap and water. A physician should examine the area if irritation or pain persists.
   Eyes
Irrigate exposed eyes with copious amounts of tepid water for at least 15 minutes. If irritation, pain, swelling, lacrimation, or photophobia persist, the patient should be seen in a health care facility.
