Section 3 - Hazards Identification

EMERGENCY OVERVIEW

Appearance: purple solid.
Warning! Causes irritation and possible burns by all routes of exposure. Possible cancer hazard. May cause cancer based on animal data. May cause allergic respiratory and skin reaction. Toxic to aquatic organisms, may cause long-term adverse effects in the aquatic environment. May be harmful if swallowed. May cause blood abnormalities. May cause lung damage. May cause adverse reproductive effects. Dangerous for the environment.
Target Organs: Lungs, cardiovascular system, red blood cells, skin, male reproductive system.


Potential Health Effects
Eye: Causes eye irritation and possible burns.
Skin: May cause skin sensitization, an allergic reaction, which becomes evident upon re-exposure to this material. Causes skin irritation and possible burns.
Ingestion: May interfere with blood clotting. May cause thyroid abnormalities. Causes digestive tract irritation with possible burns.
Inhalation: Causes delayed lung injury. May cause asthmatic attacks due to allergic sensitization of the respiratory tract. May cause asthma and shortness of breath. Causes respiratory tract irritation with possible burns.
Chronic: Cobalt compounds may cause cancer based upon animal studies. Adverse reproductive effects have been reported in animals.

Section 4 - First Aid Measures


Eyes: Immediately flush eyes with plenty of water for at least 15 minutes, occasionally lifting the upper and lower eyelids. Get medical aid.
Skin: Get medical aid. Flush skin with plenty of water for at least 15 minutes while removing contaminated clothing and shoes. Wash clothing before reuse.
Ingestion: Do not induce vomiting. If victim is conscious and alert, give 2-4 cupfuls of milk or water. Never give anything by mouth to an unconscious person. Get medical aid.
Inhalation: Remove from exposure and move to fresh air immediately. If breathing is difficult, give oxygen. Get medical aid. Do NOT use mouth-to-mouth resuscitation.
Notes to Physician: Treat symptomatically and supportively.

Section 5 - Fire Fighting Measures
