Sodium chlorate

Sodium chlorate is an inorganic chemical compound with the formula ClNaO3 and CAS number 7775-09-9. It has a molecular weight of 106.44 g/mol and appears as a white crystalline solid. This oxidizing substance is classified as dangerous, with GHS pictograms GHS03 (oxidizing) and GHS06 (toxic). It poses acute toxicity risks and belongs to the oxidizing solids category 1, requiring careful handling in industrial applications.

Sodium chlorate is a white crystalline solid that is highly soluble in water. It has a molecular weight of 106.44 g/mol and is odorless. The compound is hygroscopic, meaning it readily absorbs moisture from the air. It decomposes when heated, releasing oxygen gas. As a strong oxidizing agent, it can react vigorously with combustible materials, organic substances, and reducing agents, making it potentially hazardous during storage and handling.

Sodium chlorate is primarily used as a herbicide and defoliant in agriculture, effectively controlling weeds and facilitating crop harvesting. It serves as an oxidizing agent in various chemical processes and is utilized in the production of chlorine dioxide for water treatment and bleaching applications. The compound is also employed in the manufacturing of matches, explosives, and fireworks due to its oxidizing properties, though its use is highly regulated.

Sodium chlorate requires strict safety measures due to its oxidizing and toxic properties. Personnel must wear appropriate PPE including chemical-resistant gloves, safety goggles, and protective clothing. Work areas should be well-ventilated to prevent dust accumulation. Avoid contact with combustible materials, reducing agents, and organic substances. Use non-sparking tools and equipment. Ensure emergency shower and eyewash facilities are readily available. Never smoke or allow open flames near the substance.

Sodium chlorate must be stored in a cool, dry, well-ventilated area away from heat sources and direct sunlight. Keep containers tightly sealed to prevent moisture absorption. Store separately from combustible materials, organic substances, acids, and reducing agents to prevent dangerous reactions. Use fire-resistant storage areas with appropriate ventilation systems. Containers should be made of compatible materials and properly labeled. Implement appropriate fire detection and suppression systems in storage areas.

Immediate action is required upon contact with sodium chlorate. For skin contact, remove contaminated clothing and rinse affected area with plenty of water for at least 15 minutes. If inhaled, move the person to fresh air immediately and seek medical attention. For eye contact, flush with clean water for at least 15 minutes while holding eyelids open. If ingested, do not induce vomiting and seek immediate medical attention. Always consult medical professionals promptly.

Sodium chlorate disposal must comply with local and national environmental regulations as hazardous waste. Contact licensed waste disposal companies specializing in oxidizing substances. Never dispose of in regular trash, sewers, or water systems. Small quantities may be neutralized by qualified personnel following approved procedures. All disposal activities must be documented and reported according to regulatory requirements. Containers must be completely emptied and decontaminated before disposal.

Sodium chlorate is classified under ADR transport regulations as Class 5.1 (oxidizing substances), Packing Group II. It requires appropriate UN-specification packaging and hazard labels during transport. Vehicles must be equipped with proper ventilation and emergency equipment. Drivers need ADR certification for dangerous goods transport. The substance must be segregated from incompatible materials and secured to prevent movement during transit. Transport documents and emergency response information must accompany shipments.

Sodium chlorate is subject to comprehensive regulations under REACH, CLP, and various national legislations. It requires safety data sheets and hazard classification as Ox. Sol. 1 and Acute Tox. 3. While not currently listed as SVHC, its use is restricted in certain applications. Employers must implement risk assessments and control measures. The substance may require registration or notification depending on quantities handled. Users must comply with occupational exposure limits and environmental protection requirements.
