Composition/Information on Ingredients Chemical name Common name and synonyms CAS number Conc. % By Weight Sodium Chlorate Chlorate of Soda 7775-09-9 > 99 w/w% Chemical name of impurities, stabilizing solvents and/or additives: None Page 2 of 15 Issue Date: 11/18/2020 Sodium Chlorate Crystal 4. First-Aid Measures Inhalation If dust from the material is inhaled, remove the affected person immediately to fresh air. Oxygen or artificial respiration if needed. Induce artificial respiration with the aid of a pocket mask equipped with a one-way valve or other proper respiratory medical device. Call a POISON CENTER or doctor/physician. Skin Contact Rinse immediately contaminated clothing and skin with plenty of water before removing clothes. Get medical attention/advice if irritation develops and persists. Eye Contact Immediately flush eyes with plenty of water for at least 20 minutes. Remove contact lenses, if present and easy to do. Continue rinsing. If eye irritation persists: Get medical advice/attention. Ingestion Rinse mouth. Do not induce vomiting without advice from poison control center. If vomiting occurs, keep head low so that stomach content doesn't get into the lungs. Do not use mouth-to-mouth method if victim ingested the substance. Induce artificial respiration with the aid of a pocket mask equipped with a one-way valve or other proper respiratory medical device. Immediately call a POISON CENTER or doctor/physician. Most important Symptoms may include stinging, tearing, redness, swelling, and blurred symptoms/effects, vision. acute and delayed Indication of immediate Provide general supportive measures and treat symptomatically. In case of medical attention and shortness of breath, give oxygen. Keep victim warm. Keep victim under special treatment observation. Symptoms may be delayed. needed General information In the case of accident or if you feel unwell, seek medical advice immediately (show the label where possible). Ensure that medical personnel are aware of the material(s) involved, and take precautions to protect themselves. 5. Fire-Fighting Measures Suitable extinguishing Water spray or fog (flooding amounts). media Unsuitable DO NOT use dry chemical fire extinguishing agents containing ammonium extinguishing media compounds (such as some A:B:C agents), since an explosive compound can be formed. DO NOT use carbon dioxide, dry chemical powder or other extinguishing agents that smother flames, since they are not effective in extinguishing fires involving oxidizers. Page 3 of 15 Issue Date: 11/18/2020 Sodium Chlorate Crystal Specific hazards arising Strong oxidizer – contact with other material may cause fire or explosion; from the chemical strong oxidizer. Special protective Firefighters must use standard protective equipment including flame equipment and retardant coat, helmet with face shield, gloves, rubber boots, and in precautions for enclosed spaces, SCBA. Avoid use of leather products. firefighters Firefighting In case of fire: Evacuate area. Fight fire remotely due to the risk of explosion. equipment/instructions In the event of fire, cool tanks with water spray. Move containers from fire area if you can do so without risk. For massive fire in cargo area, use unmanned hose holder or monitor nozzles, if possible. If not, withdraw and let fire burn out. Do not allow run-off from firefighting to enter drains or water courses. Dike for water control. Specific methods Water is the only effective extinguishing media for fires involving sodium chlorate. Cool containers exposed to flames with water until well after the fire is out. General fire hazards May cause fire or explosion; strong oxidizer. Hazardous combustion Pure sodium chlorate decomposes explosively under intense fire conditions. products It initially decomposes to sodium perchlorate and begins to liberate oxygen at about 265°C. Besides oxygen, other compounds formed in a fire include chlorine, hydrogen chloride and sodium oxide. 6. Accidental Release Measures Personal precautions, Eliminate all ignition sources (no smoking, flares, sparks, or flames in protective equipment immediate area). Immediately evacuate personnel to safe areas. Keep and emergency unnecessary personnel away. Keep people away from and upwind of procedures spill/leak. Keep out of low areas. Use a NIOSH/MSHA approved respirator if there is a risk of exposure to dust/fume at levels exceeding the exposure limits. Wear appropriate protective equipment and clothing during clean- up. Do not touch damaged containers or spilled material unless wearing appropriate protective clothing. Avoid inhalation of dust. Ventilate closed spaces before entering them. Local authorities should be advised if significant spillages cannot be contained. For personal protection, see section 8 of the SDS. Methods and materials Eliminate all ignition sources (no smoking, flares, sparks, or flames in for containment and immediate area). Keep combustibles (wood, paper, oil, etc.) away from cleaning up spilled material. Collect waste material in suitable noncombustible container for disposal. Minimize dust generation and accumulation. Prevent entry into waterways, sewer, basements or confined areas. Following product recovery, flush area with water. For waste disposal, see section 13 of the SDS. Page 4 of 15 Issue Date: 11/18/2020 Sodium Chlorate Crystal Environmental Avoid discharge into drains, water courses or onto the ground. precautions 7. Handling and Storage Precautions for safe Keep away from heat. Minimize dust generation and accumulation. Provide handling appropriate exhaust ventilation at places where dust is formed. Take every precaution to avoid mixing with combustibles. Avoid breathing dust. Avoid contact with skin and eyes. In case of insufficient ventilation, wear suitable respiratory equipment. Wear appropriate personal protective equipment. Observe good industrial hygiene practices. When using, do not eat, drink or smoke. Wash hands thoroughly after handling. Practice good housekeeping. Conditions for safe Keep away from heat. Store in a cool, dry place out of direct sunlight. Store storage, including any in a well-ventilated place. Store away from incompatible materials (see incompatibilities Section 10 of the SDS). Do not store near combustible materials or readily oxidizable materials and acids. Guard against dust accumulation of this material. 8.
