Cobalt(2+) sulfate

Cobalt(2+) sulfate is an inorganic chemical compound with the formula CoO4S and CAS number 10124-43-3. This cobalt salt has a molecular weight of 155 g/mol and appears as a crystalline solid. It is classified as a hazardous substance with multiple health and environmental risks, including carcinogenic, mutagenic, and reproductive toxicity properties. The compound requires careful handling due to its classification under GHS pictograms GHS08, GHS07, and GHS09, with a danger signal word.

Cobalt(2+) sulfate is a solid crystalline compound that typically appears as red or pink crystals in its hydrated form. It is highly soluble in water, forming characteristic colored solutions. The anhydrous form has a molecular weight of 155 g/mol and the compound is stable under normal conditions. It exhibits hygroscopic properties, readily absorbing moisture from the air. The substance has no characteristic odor and demonstrates typical ionic compound behavior in aqueous solutions.

Cobalt(2+) sulfate is primarily used in industrial applications including electroplating processes, ceramic and glass coloring, and as a catalyst in chemical reactions. It serves as a source of cobalt ions in various manufacturing processes and is utilized in the production of cobalt-based pigments and dyes. The compound finds application in battery manufacturing, particularly in rechargeable battery technologies, and as a supplement in animal feed under strict regulatory controls due to its toxicity profile.

Cobalt(2+) sulfate must be handled with extreme caution due to its carcinogenic, mutagenic, and reproductive toxicity classifications. Essential personal protective equipment includes respiratory protection (P2 filter minimum), chemical-resistant gloves, safety goggles, and protective clothing. Work should be conducted in well-ventilated areas or under fume extraction systems. Avoid skin contact, inhalation, and ingestion. Implement strict hygiene measures including hand washing and changing clothes after handling. Training on hazardous substance handling is mandatory before use.

Cobalt(2+) sulfate should be stored in a cool, dry, well-ventilated area away from incompatible materials. Keep containers tightly sealed to prevent moisture absorption and contamination. Store separately from food, feed, and consumer products due to its toxic properties. Ensure storage areas are equipped with appropriate spill containment measures and emergency equipment. Access should be restricted to trained personnel only. Maintain storage temperatures within recommended ranges and protect from direct sunlight and heat sources.

In case of skin contact with cobalt(2+) sulfate, immediately remove contaminated clothing and wash the affected area thoroughly with soap and water for at least 15 minutes. For eye contact, flush immediately with clean water for 15-20 minutes while holding eyelids open. If inhaled, move the person to fresh air immediately and seek medical attention. In case of ingestion, do not induce vomiting and seek immediate medical help. Always contact emergency services and provide the safety data sheet to medical personnel.

Cobalt(2+) sulfate must be disposed of as hazardous waste through licensed waste management companies in accordance with local and European regulations. The substance cannot be disposed of in regular waste streams due to its toxic and environmental hazard classifications. Recovery and recycling should be prioritized where possible. Ensure proper labeling of waste containers and maintain documentation of disposal procedures. Small quantities may require special collection procedures, while larger amounts need professional hazardous waste treatment and disposal services.

Cobalt(2+) sulfate is classified as ADR Class 9 (Miscellaneous dangerous goods), Packing Group III for transportation purposes. It must be packaged in UN-approved containers with appropriate hazard labels and documentation. Transport vehicles require proper placarding and the driver must hold relevant dangerous goods transport certification. Shipping papers must include proper shipping name, UN number, and emergency response information. Ensure compliance with ADR regulations for loading, segregation, and route restrictions during transportation.

Cobalt(2+) sulfate is subject to extensive European regulations under REACH and CLP classifications. It carries multiple hazard classifications including Carc. 1B, Muta. 2, and Repr. 1B, requiring strict compliance with occupational exposure limits and risk management measures. The substance is regulated under various national chemical safety laws and may require registration, authorization, or notification depending on quantities used. Industrial users must implement appropriate risk management measures and provide downstream user safety information through safety data sheets.
