Potential Health Effects
----------------------------------
Inhalation:
Causes irritation to the respiratory tract, symptoms may include coughing, shortness of breath, and nausea.
Respiratory hypersensitivity, asthma may appear. Inhalation of cobalt dust and fumes is associated with an
increased incidence of lung disease.
Ingestion:
Toxic. 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:
Causes irritation to skin. Symptoms include redness, itching, and pain. May cause dermatitis.
Eye Contact:
Causes irritation, redness, and pain.
Chronic Exposure:
Repeated oral administration may produce goiter and reduced thyroid activity. Prolonged or repeated skin
exposure may cause dermatitis. Chronic exposure associated with kidney, liver, heart and lung damage.
Aggravation of Pre-existing Conditions:
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.
4. First Aid Measures
Inhalation:
Remove to fresh air. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Get medical
attention.
Ingestion:
Induce vomiting immediately as directed by medical personnel. Never give anything by mouth to an unconscious
person. Get medical attention.

COBALT CHLORIDE Page 3 of 8
Skin Contact:
Wipe off excess material from skin then immediately flush skin with plenty of water for at least 15 minutes.
Remove contaminated clothing and shoes. Get medical attention. Wash clothing before reuse. Thoroughly clean
shoes before reuse.
Eye Contact:
Immediately flush eyes with plenty of water for at least 15 minutes, lifting lower and upper eyelids occasionally.
Get medical attention immediately.
5. Fire Fighting Measures
Fire:
Not considered to be a fire hazard.
Explosion:
Not considered to be an explosion hazard.
Fire Extinguishing Media:
Use any means suitable for extinguishing surrounding fire.
Special Information:
Use protective clothing and breathing equipment appropriate for the surrounding fire.
6. Accidental Release Measures
Ventilate area of leak or spill. Wear appropriate personal protective equipment as specified in Section 8. Spills:
Sweep up and containerize for reclamation or disposal. Vacuuming or wet sweeping may be used to avoid dust
dispersal. US Regulations (CERCLA) require reporting spills and releases to soil, water and air in excess of
reportable quantities. The toll free number for the US Coast Guard National Response Center is (800) 424-
8802.
7. Handling and Storage
Keep in a tightly closed container, stored in a cool, dry, ventilated area. Protect against physical damage. Isolate
from incompatible substances. Wash hands before eating and do not eat, drink, or smoke in workplace.
Containers of this material may be hazardous when empty since they retain product residues (dust, solids);
observe all warnings and precautions listed for the product.
8. Exposure Controls/Personal Protection
Airborne Exposure Limits:
For Cobalt Compound: -OSHA Permissible Exposure Limit (PEL): 0.1 mg/m3 (TWA) Cobalt metal dust and
http://www.jtbaker.com/msds/c4928.htm 1/1/99
COBALT CHLORIDE Page 4 of 8
fume as Co -ACGIH Threshold Limit Value (TLV): inorganic cobalt compounds: 0.02 mg/m3 (TWA) as Co,
A3: Animal carcinogen.
Ventilation System:
A system of local and/or general exhaust is recommended to keep employee exposures below the Airborne
Exposure Limits. Local exhaust ventilation is generally preferred because it can control the emissions of the
contaminant at its source, preventing dispersion of it into the general work area. Please refer to the ACGIH
document, Industrial Ventilation, A Manual of Recommended Practices, most recent edition, for details.
Personal Respirators (NIOSH Approved):
If the exposure limit is exceeded, a half-face high efficiency dust/mist respirator may be worn for up to ten times
the exposure limit or the maximum use concentration specified by the appropriate regulatory agency or
respirator supplier, whichever is lowest. A full-face piece high efficiency dust/mist respirator may be worn up to
50 times the exposure limit, or the maximum use concentration specified by the appropriate regulatory agency or
respirator supplier, whichever is lowest. For emergencies or instances where the exposure levels are not known,
use a full-facepiece positive-pressure, air-supplied respirator. WARNING: Air-purifying respirators do not
protect workers in oxygen-deficient atmospheres.
Skin Protection:
Wear protective gloves and clean body-covering clothing.
Eye Protection:
Use chemical safety goggles and/or full face shield where dusting or splashing of solutions is possible. Maintain
eye wash fountain and quick-drench facilities in work area.
