Barium Carbonate 513-77-9 99 - 100% Yes
Inhalation: May cause irritation of the respiratory tract. Excessive
exposures may produce lung damage.
Ingestion: May cause excessive salivation, severe abdominal pain,
vomiting, violent diarrhea, muscle twitching progressing to muscular paralysis,
gastroenteritis and increased blood pressure. Serious cases may result in
convulsions and death.
Skin Contact: May cause irritation with redness and pain.
Eye Contact: May cause irritation, redness and pain.
Chronic Exposure: Long term inhalation of dust may lead to deposition in
lungs in sufficient quantities to produce baritosis - a benign pneumoconiosis.
This produces a radiological picture. Symptoms and abnormal signs may not be
present.
Aggravation of Pre-existing Conditions: Persons with pre-existing skin
disorders or eye problems or impaired respiratory function may 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
immediately.
Skin Contact: Immediately flush skin with plenty of soap and water for at
least 15 minutes. Remove contaminated clothing and shoes. Wash clothing before
reuse. Thoroughly clean shoes before reuse. Get medical attention if irritation
develops.
Eye Contact: Immediately flush eyes with plenty of water for at least 15
minutes, lifting upper and lower eyelids occasionally. Get medical attention if
irritation persists.
Note to Physician: Precipitate ingested soluble barium compounds as
benign insoluble barium sulfate using an Epsom (MgSO4) or a Glauber's (NaSO4)
salt solution. Dilute copiously with water or milk. Evacuate via nasogastric
aspiration or induction of emisis. Monitor electrolytes, especially potassium
(treat for hypokalemia), electrocardiogram and rhythm, and acid/base status.
Induce brisk diuresis. Calcium gluconate may be helpful for muscle spasms.
Provide oxygen by nasal cannula or mask and other supportive treatment for
symptoms as clinically indicated.
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: In the event of a fire, wear full protective
clothing and NIOSH-approved self-contained breathing apparatus with full
facepiece operated in the pressure demand or other positive pressure mode.
Ventilate area of leak or spill. Keep unnecessary and unprotected people away from area of spill. Wear appropriate personal protective equipment as specified in Section 8. Spills: Pick up and place in a suitable container for reclamation or disposal, using a method that does not generate dust.
Keep in a tightly closed container, stored in a cool, dry, ventilated area. Protect against physical damage. Isolate from incompatible substances. 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 Soluble Barium
Compounds:
OSHA Permissible Exposure Limit (PEL): 0.5 mg (Ba)/m3
ACGIH Threshold Limit Value (TLV): 0.5 mg (Ba)/m3 A4 - not classifiable as a
human 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 full facepiece particulate
respirator (NIOSH type N100 filters) may be worn for 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 impervious protective clothing, including boots,
gloves, lab coat, apron or coveralls, as appropriate, to prevent skin contact.
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: White powder.
Odor: Odorless.
