Cobalt(2+) sulfate

Cobalt(2+) sulfate is an inorganic chemical compound with the molecular formula CoO4S and CAS number 10124-43-3. This cobalt salt has a molecular weight of 155 g/mol and is classified as a highly hazardous substance due to its carcinogenic, mutagenic, and reproductive toxicity properties. It appears as crystalline powder and is widely used in industrial applications requiring cobalt compounds.

Cobalt(2+) sulfate is a crystalline solid that typically appears as red or pink crystals or powder. It is highly soluble in water, forming characteristic colored solutions. The compound is hygroscopic, meaning it readily absorbs moisture from air. It has good thermal stability under normal conditions but may decompose at high temperatures, releasing toxic sulfur oxides and cobalt compounds.

Cobalt(2+) sulfate is primarily used in electroplating processes to deposit cobalt coatings on metal surfaces. It serves as a cobalt source in the production of cobalt-based catalysts, pigments, and ceramic glazes. The compound is also utilized in the manufacturing of vitamin B12, as a drying agent in paints and inks, and in the production of other cobalt compounds for various industrial applications.

Cobalt(2+) sulfate requires strict safety measures due to its carcinogenic and sensitizing properties. Always wear appropriate personal protective equipment including respiratory protection (P2 filter minimum), chemical-resistant gloves, safety goggles, and protective clothing. Work in well-ventilated areas or under fume extraction. Avoid skin contact, inhalation, and ingestion. Implement proper hygiene measures and never eat, drink, or smoke in work areas.

Cobalt(2+) sulfate should be stored in tightly sealed containers in a cool, dry, well-ventilated area away from incompatible materials. Keep containers protected from moisture due to its hygroscopic nature. Store separately from strong bases, reducing agents, and oxidizing materials. Ensure storage areas are equipped with appropriate spill containment measures and restrict access to authorized personnel only.

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. If inhaled, move the person to fresh air immediately. For eye contact, rinse continuously with water for at least 15 minutes. If ingested, do not induce vomiting and seek immediate medical attention. Always consult a physician after any exposure.

Cobalt(2+) sulfate must be disposed of as hazardous waste according to local and national regulations. Never discharge into drains, soil, or water bodies due to its aquatic toxicity. Contact licensed hazardous waste disposal companies for proper collection and treatment. Small quantities should be neutralized and treated by qualified professionals. Always consult local environmental authorities for specific disposal requirements and approved disposal facilities.

Cobalt(2+) sulfate is classified under ADR Class 9 (Miscellaneous dangerous goods), Packing Group III. It requires appropriate UN-specification packaging and proper labeling with Class 9 hazard labels. Transport documents must include the correct shipping name and UN number. Vehicles must carry appropriate emergency equipment, and drivers need ADR training certification for Class 9 materials.

Cobalt(2+) sulfate is subject to strict regulations under REACH and CLP in Europe due to its classification as carcinogenic (1B), mutagenic (2), and toxic for reproduction (1B). It requires safety data sheets, exposure scenarios, and risk assessments. The substance may be subject to authorization requirements and restrictions on use. Employers must implement occupational exposure limits and health surveillance programs.
