crystal displays, plasma display devices and field emission devices. It is also used in making coatings in architectural glass, low pressure sodium lamps, solar collectors, and windshield glass. Indium is used in plating for bearings, alloys for solders, fusible alloys, nuclear control rods and dental alloys. Indium is used in compounds for phosphors and semiconductors. Other uses include batteries and radioisotopes.

None required Emergency Overview: A soft, silvery-white metal that does not burn in bulk but may form explosive mixtures if dispersed in air as a fine powder. Indium is relatively non-toxic and poses little immediate hazard to the health of emergency response personnel or the environment in an emergency situation.

powder may be flammable or explosive when dispersed in the air at high concentrations and exposed to heat, flame, or other ignition sources. Explosions may also occur upon contact with certain incompatible materials (see Stability and Reactivity, Section 10).
dioxide, dry chemical, or foam. Do not use direct water streams on fires where molten metal is present.
cool material exposed to flame in order to prevent molten pools of indium. Do not use direct water streams on fires where molten metal is present, due to the risk of a steam explosion that could potentially eject molten metal uncontrollably. Use a fine water mist on the front-running edge of the spill and on the top of the molten metal to cool and solidify it. Fire fighters should be fully trained and wear full protective clothing including an approved, self-contained breathing apparatus which supplies a positive air pressure within a full face-piece mask.

precautions outlined below. Molten metal should be allowed to cool and harden before cleanup. Once solidified, wear gloves, pick up and return to process. Powder or dust should be cleaned up using methods which will minimize dust generation (e.g., vacuum solids or dampen material and shovel / wet sweep). Return uncontaminated spilled material to the process if possible. Place contaminated material in suitable labelled containers for later recovery in view of the economic value of indium. Treat or dispose of waste material in accordance with all local, regional, and national requirements.
release (see also Section 8). Close-fitting safety goggles may be necessary in some circumstances to prevent eye contact with indium metal dust or fume.
management practices should always be applied in the storage and use of indium and its compounds; any releases of the product to water and soil should be prevented.
Store in a cool, dry, covered area away from incompatible materials. Solid metal suspected of containing moisture should be THOROUGHLY DRIED before being added to a molten bath. Otherwise, entrained moisture could expand explosively and spatter molten metal out of the bath. No special packaging materials are required.

well below recommended occupational exposure limits. Supply sufficient replacement air to make up for air removed by the exhaust system. Where indium metal dust or filings are being collected and transported by a ventilation system, use a non- sparking, grounded ventilation system separate from other exhaust ventilation systems. Locate dust collectors and fans outdoors if possible and provide dust collectors with explosion vents or blow out panels. Refer to appropriate NFPA Standards 484, 654, and/or 68 for specific guidance.
protection should be worn where fume or dust is generated. Where molten metal is handled, heat resistant gloves, goggles or face-shield, and clothing to protect from hot metal splash and radiant heat should be worn. Safety type boots are recommended.

vigorously with mercury (II) bromide at high temperatures (350° C). Mixtures with sulphur ignite when heated. Reacts with halogens, selenium, tellurium, arsenic or phosphorus on heating. Avoid oxidizing agents and acids.
gouging will generate indium oxide fumes. The particle size of metal fumes is largely within the respirable size range, which increases the likelihood of inhalation and deposition of the fume within the body.
extremely toxic when injected into laboratory animals with a direct effect on the heart, liver, kidneys and blood. However, indium salts are far less toxic when administered orally or by inhalation. Teratogenic effects have been reported in laboratory animals injected with indium but it is considered that the risk of developmental toxicity in humans is low. The inhalation route is by far the most significant route in the occupational setting.
Skin/Eye: Indium metal is not irritating to the eyes or skin other than by direct abrasive action of metal particles on eye or skin tissue. Soluble indium salts are very irritating to the eyes.
irritate the gastrointestinal tract if ingested.
indium compounds during the production of indium complained of tooth decay, pain in joints and bones, nervous and gastrointestinal disorders, heart pains, and general debility. However, an EPA review of indium metal suggests that “… possibly too much weight is given to a Russian report … This (these health effects) has not been reported in comparable US activities.” Indium and indium oxide are not listed as human carcinogens by the Occupational Safety and Health Administration (OSHA), the National Toxicology Program (NTP), the International Agency for Research on Cancer (IARC), the American Conference of Governmental Industrial Hygienists (ACGIH) or the European Union (EU).

Indium metal is highly insoluble, and therefore presents minimal ecological risk. However, its processing or extended exposure in the environment may lead to the release of indium in more bioavailable compound forms. As there is limited information on the fate and effects of indium compounds, care should be taken to prevent releases to the environment.
In view of the economic value of indium metal, every effort should be made to recover and reuse any spilled material. If material cannot be returned to process, dispose of only in accordance with applicable regulations.
