**** SECTION 3 - HAZARDS IDENTIFICATION ****
EMERGENCY OVERVIEW
May cause sensitization by inhalation and skin contact. May cause
long-term adverse effects in the aquatic environment.
Potential Health Effects
Eye:
Causes eye irritation. May cause conjunctivitis.
Skin:
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 cause allergic reaction.
Inhalation:
Causes respiratory tract irritation. May cause asthmatic attacks due
to allergic sensitization of the respiratory tract. May cause asthma
and shortness of breath.
Chronic:
Repeated exposure may cause sensitization dermatitis. Repeated
exposure may cause allergic respiratory reaction (asthma). Chronic
inhalation of dust may lead to restricted pulmonary function and
interstitial fibrosis.
**** 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.
Ingestion:
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. Get medical
aid if cough or other symptoms appear.
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. Dusts at sufficient concentrations can form
explosive mixtures with air. Material can spontaneously ignite
(pyrophoric) when exposed to air at normal or slightly elevated
temperatures. Flammable solid.
Extinguishing Media:
Use dry sand or earth to smother fire. DO NOT USE WATER!
**** 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. Avoid generating dusty conditions.
**** 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 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:
Use adequate general or local exhaust ventilation to keep airborne
concentrations below the permissible exposure limits.
Exposure Limits
CAS# 7440-48-4:
United Kingdom, WEL - TWA: 0.1 mg/m3 TWA

Personal Protective Equipment
Eyes:
Wear appropriate protective eyeglasses or chemical
safety goggles as described by OSHA's eye and face
protection regulations in 29 CFR 1910.133 or European
Standard EN166.
Skin:
Wear appropriate gloves to prevent skin exposure.
Clothing:
Wear appropriate protective clothing to prevent skin
exposure.
Respirators:
Follow the OSHA respirator regulations found in 29
CFR 1910.134 or European Standard EN 149. Use a
NIOSH/MSHA or European Standard EN 149 approved
respirator if exposure limits are exceeded or if
irritation or other symptoms are experienced.

acids, oxidizers.
Incompatibilities with Other Materials:
Pyrophoric cobalt decomposes acetylene in the cold and the metal
becomes incandescent. Fused ammonium nitrate can react explosively
with powdered cobalt. Pyrophoric cobal, a black powder, burns
brilliantly when exposed to air.
Hazardous Decomposition Products:
Oxides of cobalt.
Hazardous Polymerization: Has not been reported.
