Potential Health Effects
----------------------------------
Inhalation:
May cause irritation to the nose, throat, and respiratory tract. Symptoms
may include sore throat, coughing, and shortness of breath. Systemic
poisoning may occur in sensitive individuals with symptoms similar to those
of ingestion. Heavy exposure to dusts may produce a benign pneumoconiosis
(baritosis). Systemic poisoning may occur with symptoms similar to those of
ingestion. Heavy exposure to dusts can produce benign pneumoconiosis
(baritosis).
Ingestion:
May cause tightness of the muscles of the face and neck, vomiting,
diarrhea, abdominal pain, muscular tremors, anxiety, weakness, labored
breathing, cardiac irregularity, convulsions, and death from cardiac and
respiratory failure. Estimated lethal dose lies between 1 to 15 grams.
Skin Contact:
Causes irritation to skin. Symptoms include redness, itching, and pain.
Eye Contact:
Causes irritation, redness, and pain.
Chronic Exposure:
No information found.
Aggravation of Pre-existing Conditions:
Persons with pre-existing skin and nervous system disorders or impaired
respiratory or cardiac function may be more susceptible to the effects of
this 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
immediately.
Skin Contact:
Remove any contaminated clothing. Wash skin with soap or mild detergent
and water for at least 15 minutes. Wash clothes before reuse. Get medical
attention if irritation develops or persists.
Eye Contact:
Immediately flush eyes with plenty of water for at least 15 minutes,
lifting upper and lower eyelids occasionally. Get medical attention.
5. Fire Fighting Measures
Fire:
Not combustible, but substance is a strong oxidizer and its heat of
reaction with reducing agents or combustibles may cause ignition.
Explosion:
Contact with oxidizable substances may cause extremely violent combustion.
Sealed containers may rupture when heated.
Fire Extinguishing Media:
Use flooding amounts of water. Do not use dry chemical, carbon dioxide or
Halon.
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. Do not release runoff from
fire control methods to sewers or waterways. Water spray may be used to
keep fire exposed containers cool.
6. Accidental Release Measures
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.
7. Handling and Storage
Keep in a tightly closed container, stored in a cool, dry, ventilated area.
Protect against physical damage and moisture. Separate from
incompatibilities. Separate from combustibles, organic or other readily
oxidizable materials. Avoid storage on wood floors. 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 Soluble Barium Compounds:
OSHA Permissible Exposure Limit (PEL):
0.5 mg (Ba)/m3
ACGIH Threshold Limit Value (TLV):
0.5 mg (Ba)/m3
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 full facepiece respirator with
dust/mist 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. 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. Maintain eye wash fountain and quick-drench
facilities in work area.
