EMERGENCY OVERVIEW
Harmful if swallowed. Irritating to eyes. May cause sensitization by
skin contact.
Potential Health Effects
Eye:
Causes eye irritation.
Skin:
Causes skin irritation. Prolonged and/or repeated contact may cause
irritation and/or dermatitis. May cause skin sensitization, an
allergic reaction, which becomes evident upon re-exposure to this
material.
Ingestion:
May cause gastrointestinal irritation with nausea, vomiting and
diarrhea. May be harmful if swallowed. May cause allergic reaction.
Inhalation:
Causes delayed lung injury. Causes respiratory tract irritation. May
cause asthmatic attacks due to allergic sensitization of the
respiratory tract. May cause asthma and shortness of breath.
Chronic:
Cobalt compounds may cause cancer based upon animal studies.
**** 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 not
breathing, give artificial respiration. Get medical aid. Do NOT use
mouth-to-mouth resuscitation.
Notes to Physician:
**** 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.
Non-combustible, substance itself does not burn but may decompose
upon heating to produce irritating, corrosive and/or toxic fumes.
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:
Vacuum or sweep up material and place into a suitable disposal
container. Clean up spills immediately, observing precautions in the
Protective Equipment section. Avoid generating dusty conditions.
Provide ventilation.
**** SECTION 7 - HANDLING and STORAGE ****
Handling:
Use with adequate ventilation. Minimize dust generation and
accumulation. Avoid contact with skin and eyes. Keep container
tightly closed. Avoid ingestion and inhalation.
Storage:
Keep away from heat and flame. Keep away from sources of ignition.
Keep from contact with oxidizing materials. Store in a cool, dry,
well-ventilated area away from incompatible substances.
**** SECTION 8 - EXPOSURE CONTROLS, PERSONAL PROTECTION ****
Engineering Controls:
Facilities storing or utilizing this material should be equipped
with an eyewash facility and a safety shower. Use adequate general or
local exhaust ventilation to keep airborne concentrations below the
permissible exposure limits.
