First-aid measures
Inhalation: Move to fresh air and let subject blow nose. Give oxygen or artificial respiration if needed. Seek medical care immediately if toxic symptoms occur.
Skin contact: Wash off immediately with soap and plenty of water for at least 15 minutes. Remove and rinse contaminated clothing immediately with water. If irritation persists, get medical attention.
Eye contact: Rinse immediately with plenty of water, also under the eyelids for at least 15 minutes. If irritation persists get medical attention.
Ingestion: Rinse out the mouth and immediately drink a few glasses of water. Never give anything by mouth to an unconscious person. Do not induce vomiting! Give oxygen or artificial respiration if needed. Seek hospital treatment.
Notes to Medical staff: Risk of methaemoglobinemia. Not to be treated with methylthionin.
Fire-fighting measures
Extinguishing media:
- Extinguish fire with large amounts of water.
Unsuitable extinguishing media:
- Do not use powder, foam or CO2-type extinguishers!
- Do not smother the fire with a blanket!
Special exposure hazards:
- Contact with combustible material may cause fire.
- Burning produces noxious and toxic fumes.
- A fire can cause explosion when sodium chlorate is present.
- A confined container with sodium chlorate can explode if heated above the decomposition temperature (>250°C).
- Containers near heat sources must-be removed immediately or cooled with water.
Special protective equipment for fire-fighters:
- Evacuate personnel to safe areas.
- In the event of fire, wear self-contained breathing apparatus.
- When intervention in close proximity wear acid resistant over suit.
- Clean contaminated surface thoroughly.
Other information:
- Evacuate personnel to safe areas.
- Keep product and empty container away from heat and sources of ignition.
- Cool containers / tanks with water spray.
- Control the use of water due to environmental risk.
- Depending on wind direction, warn people of the danger of intoxication, close doors and windows,
and switch off the ventilation.
Accidental release measures
Environmental cleanup procedures:
- Dam with sand or similar and collect in a plastic or metal container for disposal.
- Do not use sawdust, peat, bark or other combustible materials.
- Flush with large amounts of water.
- Contact experts in case of large spillages.
- Notify appropriate authorities.
- Waste on the ground must be collected.
- Solutions should not be drained into sewage systems.
Personal precautions:
- Personal protective equipment is necessary when taking care of a large spillage.
- Sources of ignition must be kept away.
- Keep away from incompatible products.
Handling and storage
Handling
Technical measures:
- Use only inert lubricants and packings for pumps, valves and other equipment when handling chlorate or chlorate solution.
- Exchange lubricants at regular intervals.
Safe handling advice:
- Do not eat , drink, or smoke when handling the product.
- Electrical supply and distribution points are to be cleaned periodically from dust.
- Avoid contact with the incompatible materials given below (incompatible products).
- Keep containers closed when not in use.
- Avoid contact with skin and eyes.
- Keep away from heat and sources of ignition.
Precautions for safe handling:
- Chlorates should be handled so as to avoid the scattering of dust.
- Any operation that may cause dust should be ventilated with a suction fan.
- The dust should be collected and disposed of carefully.
Storage
Storage conditions:
- Store in a cool, dry and fireproof area away from sources of heat and ignition, including friction and impact.
- Keep away from food and beverages.
- Store in original container.
- Provide aspiration of dust at source with filtration or washing with water.
- Provide electrical earthing and waterproof equipment.
- Provide an anti-corrosion protected electrical equipment in a bunded area.
Big bags:
- Store on gravel or crushed stone. Avoid storing in an asphalt-paved area.
- The separation between stacks should be at least 8 - 10 m.
- Maintain a safe distance from buildings.
Bulk:
- Store in permanent bins of non-combustible construction.
- Store separately from all other materials.
Safe packaging materials:
- Use UN-approved metal drums or plastic lined bags. Do not reuse big bags.
Materials to avoid
-Sodium chlorate should be stored separate from organic substances, strong acids, phosphorus, sulphur, sulphides, powdered metals, ammonium salts.
