Cobalt(II) Chloride 7646-79-9 90 - 100% Yes
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.
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.
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.
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.
Ventilate area of leak or spill. Wear appropriate personal protective equipment as specified in Section 8
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.
Airborne Exposure Limits: For Cobalt Compound:-OSHA
Permissible Exposure Limit (PEL):0.1 mg/m3 (TWA) Cobalt metal dust and 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
and engineering controls are not feasible, a half-face high efficiency
particulate respirator (NIOSH type N100 filter) 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 particulate respirator (NIOSH type N100 filter) 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.
If oil particles (e.g. lubricants, cutting fluids, glycerine, etc.) are present,
use a NIOSH type R or P filter. 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.
Appearance: Rose-red crystals.
