Respiratory hypersensitivity, asthma may appear.

5 Inhalation of cobalt dust and fumes is associated with an increased incidence of lung disease. Ingestion: Causes abdominal pain, nausea, vomiting, flushing of the face and ears, mild hypotension, rash, and ringing in the ears. May have cumulative toxic action where elimination cannot keep pace with absorption. Large amounts depress erythrocyte production. Skin Contact: May cause dermatitis. Causes irritation to skin. Symptoms include redness, itching, and pain. Eye Contact: Causes irritation, redness, and pain. CHRONIC: Repeated oral administration may produce goiter and reduced thyroid activity. Prolonged or repeated skin exposure may cause dermatitis. Chronic exposure associated with kidney, heart and lung damage. 3.

6 None NOTE: ALL WHMIS required information is included in appropriate sections based on the ANSI format. This product has been classified in accordance with the hazard criteria of the CPR and the SDS contains all the information required by the CPR, EU Directives and the Japanese Industrial Standard JIS Z 7250: 2000. 4. FIRST-AID MEASURESSKIN EXPOSURE: If this product contaminates the skin, begin decontamination with running water. Minimum flushing is for 5 minutes. Remove exposed or contaminated clothing, taking care not to contaminate eyes. The contaminated individual should seek medical attention if any adverse effect occurs. EYE EXPOSURE: If this product enters the eyes, open contaminated individual's eyes while under gently running water. Use sufficient force to open eyelids.

7 Remove contact lenses if worn. Have contaminated individual "roll" eyes. Minimum flushing is for 15 minutes. Contaminated individual must seek immediate medical attention. INHALATION: If dusts generated by this product are inhaled, remove contaminated individual to fresh air. If necessary, use artificial respiration to support vital functions. Seek medical attention if breathing distress continues. INGESTION: Routine use of this product is not expected to cause any situation which could lead to ingestion. If this product is swallowed, CALL PHYSICIAN OR POISON CONTROL CENTER FOR MOST CURRENT INFORMATION. If professional advice is not available, do not induce vomiting. Never induce vomiting or give diluents (milk or water) to someone who is unconscious, having convulsions, or unable to swallow.

8 MEDICAL CONDITIONS AGGRAVATED BY EXPOSURE: Persons with pre-existing skin disorders or eye problems, or impaired liver, kidney or respiratory function may be more susceptible to the effects of the substance. Persons with allergies or sensitivity to cobalt may also be more susceptible to the effects of the substance. RECOMMENDATIONS TO PHYSICIANS: Treat symptoms and eliminate overexposure. 5. FIRE-FIGHTING data SHEET Page 3 of 6 FLASH POINT: Non-Flammable AUTOIGNITION TEMPERATURE: Not Applicable FLAMMABLE LIMITS (in air by volume, %): Lower NA Upper NA FIRE EXTINGUISHING MATERIALS: Use fire extinguishing methods below: Water Spray: Yes Carbon Dioxide: Yes Foam: Yes Dry Chemical: Yes Halon: Yes Other: Any C Class If involved in a fire, use water spray to cool containers. UNUSUAL FIRE AND EXPLOSION HAZARDS: Not combustible, but substance is a strong oxidizer and its heat of reaction with reducing agents or combustibles may cause ignition.

9 Explosion Sensitivity to Mechanical Impact: No Explosion Sensitivity to Static Discharge: No SPECIAL FIRE-FIGHTING PROCEDURES: Incipient fire responders should wear eye protection. Structural firefighters must wear Self-Contained Breathing Apparatus and full protective equipment. Isolate materials not yet involved in the fire and protect personnel. Move containers from fire area if this can be done without risk; otherwise, cool with carefully applied water spray. If possible, prevent runoff water from entering storm drains, bodies of water, or other environmentally sensitive areas. 6. ACCIDENTAL RELEASE MEASURESSPILL AND LEAK RESPONSE: Proper protective equipment should be used. Stop the flow of material, if this can be done SAFETY . Contain discharged material. For spills of solid material, sweep-up or vacuum spilled solid, minimizing the generation of dust.
