----------------- ------------ ------------ ----------
Barium Sulfate 7727-43-7 97 - 100% Yes
Inhalation: Not expected to be a health hazard.
Ingestion: Not expected to be a health hazard.
Skin Contact: No adverse effects expected.
Eye Contact: No adverse effects expected but dust may cause
mechanical irritation.
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 even though symptoms and abnormal signs may
not be present.
Aggravation of Pre-existing Conditions: No information found.
Inhalation: Remove to fresh air. Get medical
attention for any breathing difficulty.
Ingestion: Give several glasses of water to drink to dilute. If
large amounts were swallowed, get medical advice.
Skin Contact: Wash exposed area with soap and water. Get medical advice
if irritation develops.
Eye Contact: Wash thoroughly with running water. Get medical advice if
irritation develops.
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. Wear appropriate personal protective equipment as specified in Section 8. Spills:
Keep in a tightly closed container. Protect from physical damage. Store in a cool, dry, ventilated area away from sources of heat, moisture and incompatibilities. 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: -OSHA Permissible Exposure
Limit (PEL): 15 mg/m3 total dust, 5 mg/m3 respirable dust
-ACGIH Threshold Limit Value (TLV): 10 mg/m3 (TWA)
Ventilation System: In general, dilution ventilation is a satisfactory
health hazard control for this substance. However, if conditions of use create
discomfort to the worker, a local exhaust system should be considered.
Personal Respirators (NIOSH Approved): If the exposure limit is exceeded
and engineering controls are not feasible, a half facepiece particulate
respirator (NIOSH type N95 or better filters) 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 particulate respirator (NIOSH type N100 filters) 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. Maintain eye wash fountain
and quick-drench facilities in work area.
Appearance: Fine, white powder.
Odor: Odorless.
Solubility: Insoluble in water.
Specific Gravity: 4.5 @ 15 (59F)

Vapor Density (Air=1): No information found.
Vapor Pressure (mm Hg): No information found.
Evaporation Rate (BuAc=1): No information found.
Stability: Stable under ordinary conditions of use
and storage.
Hazardous Decomposition Products: Burning may produce sulfur oxides.
Hazardous Polymerization: Will not occur.
Incompatibilities: Aluminum, phosphorus.
Conditions to Avoid: Dusting and incompatibles.
No LD50/LC50 information found relating to normal routes of occupational exposure.
