Literature sources indicate that this chemical is nonflammable. (NTP, 1992)
Not combustible. Gives off irritating or toxic fumes (or gases) in a fire.
Health Hazards · 1 item
SYMPTOMS: Symptoms of exposure to this compound via inhalation include coughing and shortness of breath. Inhalation may cause irritation of the respiratory tract and mucous membranes. It may also cause permanent disability. Ingestion of this compound may result in nausea, vomiting, abdominal pain, vasodilatation, mild hypotension, rash and ringing in the ears. It can cause irritation, redness and pain on skin or eye contact. Skin contact may also result in allergic reactions. Other symptoms include headache and nervous system disturbances. Repeated ingestion may produce a goiter and reduce thyroid activity. Prolonged or repeated skin contact may cause dermatitis. Lung disease sometimes occurs on inhalation of this type of compound.

Applications · 3 items
UsesUsual source of water-soluble cobalt since it is the most economical and it shows less tendency to deliquesc or dehydrate than the chloride or nitrate. Used in storage batteries; in Co-electroplating baths; as drier for lithographic inks, varnishes; in ceramics, enamels, glazes to prevent discoloring; in Co pigments for decorating porcelain.
UsesCobalt(II) sulfate heptahydrate is used in the preparation of pigments and other cobalt salts. It is used in storage batteries and electroplating baths, sympathetic inks, and as an additive to soils and animal feeds.

Reactivity Profile · 1 item
Acidic salts, such as COBALT SULFATE HEPTAHYDRATE, are generally soluble in water. The resulting solutions contain moderate concentrations of hydrogen ions and have pH's of less than 7.0. They react as acids to neutralize bases. These neutralizations generate heat, but less or far less than is generated by neutralization of inorganic acids, inorganic oxoacids, and carboxylic acid. They usually do not react as either oxidizing agents or reducing agents but such behavior is not impossible. Many of these compounds catalyze organic reactions.
Chemical DangersDecomposes above 100 °C . This produces toxic fumes of sulfur oxides. The dust reacts with strong oxidants. This generates fire and explosion hazard.
Air and Water ReactionsWater soluble. The resulting solution is acidic.

Fires involving this material can be controlled with a dry chemical, carbon dioxide or Halon extinguisher. (NTP, 1992)
In case of fire in the surroundings, use appropriate extinguishing media.
First Aid Measures · 4 items
Fresh air, rest. Artificial respiration may be needed. Refer for medical attention.
Remove contaminated clothes. Rinse and then wash skin with water and soap.
First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention.
Rinse mouth. Give one or two glasses of water to drink. Refer for medical attention .
First Aid · 1 item
EYES: First check the victim for contact lenses and remove if present. Flush victim's eyes with water or normal saline solution for 20 to 30 minutes while simultaneously calling a hospital or poison control center. Do not put any ointments, oils, or medication in the victim's eyes without specific instructions from a physician. IMMEDIATELY transport the victim after flushing eyes to a hospital even if no symptoms (such as redness or irritation) develop.
Safe StorageSeparated from strong oxidants.
Nonfire Spill Response · 1 item
SMALL SPILLS AND LEAKAGE: If you spill this chemical, you should dampen the solid spill material with water, then transfer the dampened material to a suitable container. Use absorbent paper dampened with water to pick up any remaining material. Seal your contaminated clothing and the absorbent paper in a vapor-tight plastic bag for eventual disposal. Wash all contaminated surfaces with a soap and water solution. Do not reenter the contaminated area until the Safety Officer (or other responsible person) has verified that the area has been properly cleaned.
Spillage Disposal · 1 item
Personal protection: particulate filter respirator adapted to the airborne concentration of the substance. Do NOT let this chemical enter the environment. Sweep spilled substance into covered containers. If appropriate, moisten first to prevent dusting. Carefully collect remainder. Then store and dispose of according to local regulations.
Eye PreventionWear safety goggles or eye protection in combination with breathing protection if powder.
Inhalation RiskEvaporation at 20 °C is negligible; a harmful concentration of airborne particles can, however, be reached quickly when dispersed.
