Section 3 - HAZARDS IDENTIFICATION
EMERGENCY OVERVIEW
Highly flammable.
Potential Health Effects
Eye:
May cause eye irritation.
Skin:
May cause skin irritation.
Ingestion:
May cause irritation of the digestive tract. May cause cardiac disturbances. The toxicological properties of this substance have not been fully investigated. May cause central nervous system depression.
May cause nausea, vomiting, abdominal pain, and increased salivation.
Inhalation:
May cause respiratory tract irritation. May cause pulmonary edema and severe respiratory disturbances.
Chronic:
The lungs of rats exposed daily to In2O3 at concentrations from 24-97 mg/m3 for a total of 224 hrs showed evidence of widespread alveolar edema, which differs from the usual toxic edema fluid by being granular and containing a few alveolar phagocytes, polymorphonuclear cells, & nuclear debris. The injury was further characterized by alteration of the alveolar walls by spindle-shaped & other type cells. The lesion showed little change either during exposure or after a 12-week postexposure period, & no fibrosis resulted from the healing process. Thus, In2O3 dust uniquely produces a widespread alveolar stasis resembling alveolar proteinosis in which alveolar clearance is reduced. Associated chronic respiratory insufficiency, recurrent acute pneumonitis, or complicating infections may result in a fatal outcome.

Section 4 - FIRST AID MEASURES
Eyes: Immediately flush eyes with plenty of water for at least 15 minutes, occasionally lifting the upper and lower eyelids. Get medical aid.
Skin:
Get medical aid. Flush skin with plenty of water for at least 15 minutes while removing contaminated clothing and shoes. Wash clothing before reuse.
Ingestion:
Never give anything by mouth to an unconscious person. Get medical aid. Do NOT induce vomiting. If conscious and alert, rinse mouth and drink 2-4 cupfuls of milk or water.
Inhalation:
Remove from exposure and move to fresh air immediately. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Get medical aid.
Notes to Physician:

Section 5 - FIRE FIGHTING MEASURES
General Information:
As in any fire, wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear. Flammable solid. May burn rapidly with flare burning effect. May re-ignite after fire is extinguished. Dousing metallic fires with water may generate hydrogen gas, an extremely dangerous explosion hazard.
Extinguishing Media:
Use only graphite powder, soda ash, powdered sodium chloride, or an appropriate metal-fire-extinguishing dry powder. Dousing metallic fires with water may generate hydrogen gas, an extremely dangerous explosion hazard, particularly if fire is in a confined environment.

Section 6 - ACCIDENTAL RELEASE MEASURES
General Information: Use proper personal protective equipment as indicated in Section 8.
Spills/Leaks:
Clean up spills immediately, observing precautions in the Protective Equipment section. Scoop up with a nonsparking tool, then place into a suitable container for disposal. Avoid generating dusty conditions. Remove all sources of ignition. Provide ventilation.

Section 7 - HANDLING and STORAGE
Handling:
Wash thoroughly after handling. Remove contaminated clothing and wash before reuse. Use with adequate ventilation. Minimize dust generation and accumulation. Avoid contact with eyes, skin, and clothing. Keep container tightly closed. Keep away from heat, sparks and flame. Do not pressurize, cut, weld, braze, solder, drill, grind, or expose empty containers to heat, sparks or open flames.
Avoid breathing dust.
Storage:
Keep away from sources of ignition. Store in a tightly closed container. Store in a cool, dry, well-ventilated area away from incompatible substances. Flammables-area.
