Indium dust

Airborne particulate from indium metal and indium compounds.

Airborne form

dust

The form describes what is suspended in air at the point of exposure. A material can produce more than one form, such as dust during handling and fume during heating.

Evidence

The current NIOSH Pocket Guide sets a 0.1 mg/m³ time-weighted-average REL for indium, notes that powdered or dust-form indium may ignite, and reports eye, skin, and respiratory irritation, possible liver, kidney, heart, and blood effects, and pulmonary edema.

NIOSH REL TWA 0.1 mg/m³. Noncombustible Solid in bulk form, but may ignite in powdered or dust form. Exposure Routes inhalation, ingestion, skin and/or eye contact. Symptoms irritation eyes, skin, respiratory system; possible liver, kidney, heart, blood effects; pulmonary edema.

NIOSH reports irritation of the eyes, skin, and respiratory system, possible effects on the liver, kidneys, heart, and blood, and pulmonary edema from indium exposure.

A NIOSH exposure study at an indium–tin oxide production and reclamation facility found that powder-transfer, sanding, cleaning, and indium-material handling tasks were associated with increased respirable or inhalable indium exposure; the authors identify these tasks as targets for exposure controls.

Tasks associated with increased respirable indium included sanding, powder transfer tasks in reclaim, powder transfer tasks in refinery, and handling indium materials. Tasks associated with increased inhalable indium included powder transfer tasks in ITO production, cleaning cylinder or tile, and handling indium material tasks.
