Fire Hazards：
Not combustible but enhances combustion of other substances. Gives off irritating or toxic fumes (or gases) in a fire. Risk of fire and explosion on contact with combustible substances.
Safe Storage：
Separated from combustible substances and reducing agents. Well closed.
Fire Fighting：
In case of fire in the surroundings, use appropriate extinguishing media.
Eye Prevention：
Wear safety goggles or eye protection in combination with breathing protection if powder.
Adverse Effects：
Asthma - Reversible bronchoconstriction (narrowing of bronchioles) initiated by the inhalation of irritating or allergenic agents.
Exposure Routes：
The substance can be absorbed into the body by inhalation of its aerosol and by ingestion.
Fire Prevention：
NO contact with combustible substances or reducing agents.
Hazards Summary：
Causes somnolence, diarrhea, and weight loss in oral lethal-dose studies of rats; [RTECS] A fire hazard on contact with combustible materials; A skin, eye, and respiratory tract irritant; May cause skin sensitization and asthma; May have effects on the heart, thyroid, and bone marrow (cardiomyopathy, goiter, and polycythemia); Possibly toxic to reproduction and teratogenic, based on animal studies; [ICSC] An oxidizing agent that may intensify fire; An irritant; May cause skin and respiratory sensitization; [Alfa Aesar MSDS] See Cobalt. See NITRATES and NITRITES.
Inhalation Risk：
A harmful concentration of airborne particles can be reached quickly when dispersed, especially if powdered.
Skin Prevention：
Protective gloves. Protective clothing.
Spillage Disposal：
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. Do NOT absorb in saw-dust or other combustible absorbents.
First Aid Measures：
Ingestion First Aid: Rinse mouth. Give one or two glasses of water to drink. Refer for medical attention .
Signs and Symptoms：
Ingestion Exposure: Abdominal pain. Nausea. Vomiting.
Exposure Prevention：
AVOID ALL CONTACT! IN ALL CASES CONSULT A DOCTOR!
Ingestion Prevention：
Do not eat, drink, or smoke during work. Wash hands before eating.
Inhalation Prevention：
Use local exhaust or breathing protection.
Regulatory Information：
New Zealand EPA Inventory of Chemical Status: Cobalt (II) nitrate, hexahydrate: Does not have an individual approval but may be used under an appropriate group standard
Other Safety Information：
Chemical Assessment: IMAP assessments - Cobalt nitrate: Human health tier II assessment
Threshold Limit Values (TLV)：
(as Co, inhalable fraction): 0.02 mg/m
Effects of Long Term Exposure：
Repeated or prolonged contact may cause skin sensitization. Repeated or prolonged inhalation may cause asthma. The substance may have effects on the heart, thyroid and bone marrow. This may result in cardiomyopathy, goiter and polycythemia. This substance is possibly carcinogenic to humans. Animal tests show that this substance possibly causes toxic effects upon human reproduction. Animal tests show that this substance possibly causes malformations in human babies.
