Section 3 - Hazards Identification

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

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.
Extinguishing Media: Substance is noncombustible; use agent most appropriate to extinguish surrounding fire.

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.

Carcinogenicity:
CAS# 7631-86-9: Not listed by ACGIH, IARC, NTP, or CA Prop 65.
CAS# 7646-79-9:


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: No data available.
Mutagenicity: No data available.
Neurotoxicity: No data available.
Other Studies:

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.

Section 13 - Disposal Considerations

Chemical waste generators must determine whether a discarded chemical is classified as a hazardous waste. US EPA guidelines for the classification determination are listed in 40 CFR Parts 261.3.
