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
Working clothes worn by chlorate workers should be washable and . Not worn away from immediate work area; they should be washed and rinsed each day. Overalls, hand and arm protection such as plastic gloves, washable head covering and foot protection such as rubber boots. The dust should be reduced to a minimum; dust respirators may be necessary.
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
Zinc chlorate in contact with concentrated sulfuric acid is likely to cause explosions and/or fire. A combination of finely divided aluminum with finely divided. A mixture of organic matter plus zinc chlorate may liberate oxygen and heat explosively.
Decomposition
The tetrahydrated salt of zinc chlorate decomposition explosively at 60 C. When heated to decomposition it emits toxic fumes of hydrogen chloride and zinc oxide.

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
Dangerous fire risk in contact with organic materials. Tetrahydrate 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.
Hazards
These substances will accelerate burning when involved in a fire. Some may decompose explosively when heated or involved in a fire. May explode from heat or contamination. Some will react explosively with hydrocarbons (fuels). May ignite combustibles (wood, paper, oil, clothing, etc.). Containers may explode when heated. Runoff may create fire or explosion hazard.
Combustion products
Fire may produce irritating, corrosive and/or toxic gases.

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 Skin.

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 patient to fresh air. Monitor for respiratory distress. If cough or difficulty breathing develops, evaluate for respiratory tract irritation, bronchitis, or pneumonitis. Administer oxygen and assist ventilation as required. Treat bronchospasm with beta2 agonist and corticosteroid aerosols.
   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.
