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.
Potential Health Effects: Relatively non-toxic to humans by inhalation or ingestion. Chronic exposure may cause irritation to the
lungs and gastrointestinal disorders. It is not considered a human carcinogen by the OSHA, NTP, ACGIH, IARC or the EU (see
Toxicological Information, Section 11).
Potential Environmental Effects: In the form in which this product is sold, it has low bioavailability, and does not pose any
significant environmental risks. Releases of the product to water and soil should, nevertheless, be prevented (see Ecological
Information, Section 12).
SECTION 3. COMPOSITION / INFORMATION ON INGREDIENTS
CAS Registry No.
SECTION 4. FIRST AID MEASURES
Symptoms: Mild irritation: If irritation occurs, cautiously rinse eye(s) with lukewarm, gently flowing water for 5
minutes, while holding the eyelids open. If eye irritation persists, get medical advice/attention.
Skin Contact: Symptoms: No health effects expected. If irritation does occur, flush with lukewarm, gently flowing water for 5
minutes. If irritation occurs, obtain medical advice. If splashed by molten metal, flush contact area to solidify and cool but do not
attempt to remove encrusted material or clothing. Cover burns and seek medical attention immediately.
Inhalation: Symptoms: Possible respiratory irritation: If symptoms are experienced remove source of contamination or move
victim from exposure area to fresh air immediately. Get medical advice/attention if you feel unwell or are concerned.
Ingestion: Symptoms: If swallowed, no specific intervention is indicated as this material is not likely to be hazardous by
ingestion. However, if you feel unwell or are concerned, get medical advice/attention.
SECTION 5. FIRE FIGHTING MEASURES
Fire and Explosion Hazards: Massive metal is not considered a fire or explosion hazard. Finely-divided indium metal dust or
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,
Extinguishing Media: Use any means of extinction appropriate for surrounding fire conditions such as water spray, carbon
dioxide, dry chemical, or foam. Do not use direct water streams on fires where molten metal is present.
Fire Fighting: Indium metal has a low melting point (156°C). Therefore, if possible move this material from the fire area and/or
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.

SECTION 6. ACCIDENTAL RELEASE MEASURES
Procedures for Cleanup: Control source of spillage if possible to do so safely. Clean up spilled material immediately, observing
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.
Personal Precautions: Protective clothing, gloves, and a respirator are recommended for persons responding to an accidental
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.
Environmental Precautions: Indium metal has low bioavailability and poses no immediate ecological risks. However, good
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.
SECTION 7. HANDLING AND STORAGE
Store in a cool, dry, covered area away from incompatible materials. Solid metal suspected of containing moisture should be
spatter molten metal out of the bath. No special packaging materials are required.
SECTION 8. EXPOSURE CONTROLS / PERSONAL PROTECTION
Occupational Exposure Guidelines:
NOTE: OEGs for individual jurisdictions may differ from those given above. Check with local authorities for the applicable OEGs in your
ACGIH - American Conference of Governmental Industrial Hygienists; OSHA - Occupational Safety and Health Administration; NIOSH -
National Institute for Occupational Safety and Health. TLV – Threshold Limit Value, PEL – Permissible Exposure Limit, REL – Recommended
NOTE: The selection of the necessary level of engineering controls and personal protective equipment will vary depending upon
the conditions of use and the potential for exposure. The following are therefore only general guidelines that may not fit all
circumstances. Control measures to consider include:
Ventilation: Use adequate local or general ventilation to maintain the concentration of indium fumes in the working environment
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.
Protective Clothing: Work clothes and gloves are recommended to prevent prolonged or repeated direct skin contact. Eye
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.
Respirators: Where indium dust or fumes are generated and cannot be controlled in the working environment to within
acceptable levels by engineering means, use appropriate NIOSH-approved respiratory protection equipment (a 42CFR84 Class
N, R or P-95 particulate filter cartridge or better).
General Hygiene Considerations: Always practice good personal hygiene. Refrain from eating, drinking, or smoking in work
areas. Thoroughly wash hands before eating, drinking, or smoking in appropriate, designated areas.

SECTION 9. PHYSICAL AND CHEMICAL PROPERTIES
Soft, silvery-white metal
Negligible @ 20°C
(Water = 1)
Insoluble in water
Stability & Reactivity: Indium is stable and not considered reactive under normal temperatures and pressures. Hazardous
polymerization or runaway reactions will not occur.
Incompatibilities: An explosive reaction may occur on contact with dinitrogen tetraoxide dissolved in acetonitrile. Indium reacts
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.
Hazardous Decomposition Products: High temperature operations such as oxy-acetylene cutting, electric arc welding or arc-air
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.
SECTION 11. TOXICOLOGICAL INFORMATION
General: The information available on the toxic properties of indium in humans is limited. It is known that soluble indium salts are
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.
tissue. Soluble indium salts are very irritating to the eyes.
Inhalation/Ingestion: Inhalation of indium fume or dust may cause irritation and damage to the respiratory tract. It may also
irritate the gastrointestinal tract if ingested.
Chronic: Prolonged exposure to indium fume or dust may cause irritation and damage to the lung. Russian workers exposed to
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).

SECTION 12. ECOLOGICAL INFORMATION
Indium metal is highly insoluble, and therefore presents minimal ecological risk. However, its processing or extended exposure in
fate and effects of indium compounds, care should be taken to prevent releases to the environment.
SECTION 13. DISPOSAL CONSIDERATIONS
In view of the economic value of indium metal, every effort should be made to recover and reuse any spilled material. If material
