EMERGENCY OVERVIEW
Appearance: clear blue solid.
Warning! Possible cancer hazard. May cause cancer
based on animal data. May cause irritation.
Target Organs: None.
Potential Health Effects
Eye:
Dust may cause mechanical irritation. Exposure to solid may cause
pain and redness.
Skin:
Dust causes mechanical irritation. Excessive drying of the skin may
result from repeated or prolonged contact.
Ingestion:
May cause gastrointestinal irritation with nausea, vomiting and
diarrhea. Expected to be a low ingestion hazard.
Inhalation:
Dust is irritating to the respiratory tract.
Chronic:
Possible cancer hazard based on tests with laboratory animals.
Cobalt dichloride is an IARC Group 2B chemical.
|
Section 4 - First Aid Measures
|
Eyes:
Get medical aid. Immediately flush eyes with plenty of water for at l
east 15 minutes.
Skin:
Get medical aid if irritation develops or persists. Flush skin with
plenty of soap and water.
Ingestion:
Never give anything by mouth to an unconscious person. Get medical
aid. Do NOT induce vomiting. If conscious and alert, rinse mouth and
drink 2-4 cupfuls of milk or water.
Inhalation:
Remove from exposure and move to fresh air immediately. If not
breathing, give artificial respiration. If breathing is difficult,
give oxygen. Get medical aid.
Notes to Physician:
Treat symptomatically and supportively.
|
Section 5 - Fire Fighting Measures
|
General Information:
As in any fire, wear a self-contained breathing apparatus in
pressure-demand, MSHA/NIOSH (approved or equivalent), and full
protective gear. During a fire, irritating and highly toxic gases
may be generated by thermal decomposition or combustion.

|
Section 6 - Accidental Release Measures
|
General Information: Use proper personal protective equipment as indicated
in Section 8.
Spills/Leaks:
Clean up spills immediately, observing precautions in the Protective
Equipment section. Sweep up or absorb material, then place into a
suitable clean, dry, closed container for disposal. Avoid generating
dusty conditions. Provide ventilation.
|
Section 7 - Handling and Storage
|
Handling:
Wash thoroughly after handling. Remove contaminated clothing and
wash before reuse. Use with adequate ventilation. Minimize dust
generation and accumulation.
Storage:
Store in a cool, dry place. Keep containers tightly closed.
|
Section 8 - Exposure Controls, Personal Protection
|
Engineering Controls:
Use process enclosure, local exhaust ventilation, or other
engineering controls to control airborne levels below recommended
exposure limits. Facilities storing or utilizing this material should
be equipped with an eyewash facility and a safety shower.

- IARC:
Group 2B carcinogen (listed as Soluble cobalt (II) salts).
Epidemiology:
Amorphous silica has been tested for carcinogenicity in a
variety of animal studies by a number of routes. Most tests
were either negative or inadequate because of poorly
defined physiochemical characteristics of the silica.
Teratogenicity:
No data available.
Reproductive Effects:

Section 12 - Ecological Information
|
Ecotoxicity:
Water flea Daphnia: >1000mg/l; 24 Hrs.; OECD 202
No data available.
Environmental:
Because of its low water solubility, amorphous silica gel is expected
to cause little oxygen depletion in aquatic systems. It is expected
to have a low potential to affect aquatic organisms. It is expected
to be resistant to biodegradation but is unlikely to bioconcentrate.
Physical:
No information available.
Other:
No information available.
