3. Hazards Identification
Potential Health Effects
Inhalation:
Excessive concentrations of a nuisance dust may cause nuisance condition such as coughing, sneezing, and nasal irritation. Repeated
inhalation may cause delayed lung injury.
Ingestion:
Barite is considered to be relatively non-toxic due to non-absorption.
Skin Contact:
Direct contact may cause dryness and itching.
Eye Contact:
Direct contact may cause mechanical irritation.
Aggravation of Pre-existing Conditions:
No information found.
4. First Aid Measures
Inhalation:
Remove to fresh air. Get medical attention for any breathing difficulty.
Ingestion:
Treat symptomatically. If symptoms persist, seek medical advice.
Skin Contact:
Cotton gloves may be used if skin becomes excessively dry. Apply skin moisturizer.
Eye Contact:
Wash thoroughly with running water. Get medical advice if irritation develops.
5. Fire Fighting Measures
Fire:
Not considered a fire hazard.
Explosion:
Not considered an explosion hazard.
Fire Extinguishing Media:
Use any means suitable for extinguishing surrounding fire.
6. Accidental Release Measures
No special precautions are required for clean up.
7. Handling and Storage
Keep in a tightly closed container, stored in a cool, dry, ventilated area. Protect against physical damage. 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:
OSHA Permissible Exposure Limit (PEL):
15 mg/m3 total dust, 5 mg/m3 respirable fraction for nuisance dusts.
ACGIH Threshold Limit Value (TLV):
10 mg/m3 total dust containing no asbestos
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 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.
Skin Protection: Gloves, apron or coveralls.
Eye Protection: GOGGLES.
