Potential Hazards/Toxicity

Indium phosphide may be harmful if ingested, inhaled, or absorbed through the skin. It may cause irritation to the respiratory tract, gastrointestinal tract, skin, and eyes. It is classified by IARC as Group 2A, probably carcinogenic to humans. Exposure to indium compounds may cause pain in the joints and bones, tooth decay, heart pain, nervous and gastrointestinal disorders, weight loss, pulmonary edema, pneumonia, and damage to the brain, blood, liver, spleen, and kidneys. Exposure to inorganic phosphorus compounds may cause hemorrhages and damage to liver, kidneys, and bone structure.

Engineering Controls

Chemical fume hood. Adequate exhaust and capture filtration.

Personal Protective Equipment (PPE)

Respirator Protection

If lab personnel would like to use respirator on a voluntary basis, they must be trained and fit-tested by EH&S. This is a regulatory requirement. (http://or.ucsf.edu/ehs/8193-DSY/version/default/part/4/data/)

Hand Protection

Handle with gloves. Nitrile gloves are recommended.

NOTE: Consult with your preferred glove manufacturer to ensure that the gloves you plan on using are compatible with indium phosphide.

Eye Protection

ANSI approved, tight-fitting glasses/goggles.

Skin and Body Protection

Appropriately-fitting lab coat, long pants, closed-toe shoes.

Hygiene Measures

Avoid contact with skin, eyes, and clothing. Wash hands before breaks and after handling.

First Aid Procedures

If inhaled

Move person into fresh air. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Consult a physician.

In case of skin contact

Flush with plenty of water for at least 15 minutes while removing contaminated clothing. Consult a physician.

In case of eye contact

Flush eyes with plenty of water for at least 15 minutes lifting upper and lower eyelids and removing contact lenses. Consult a physician.

If swallowed

Do not induce vomiting. Never give anything by mouth to an unconscious person. Rinse mouth with water. Consult a physician.

Special Handling and Storage Requirements

Precautions for safe handling: Avoid contact with skin, eyes, and clothing. Avoid inhalation and ingestion. Avoid dust formation. Provide adequate exhaust ventilation. Ensure normal measures for preventative fire protection.

Conditions for safe storage: Keep container tightly closed in a cool, dry, and well-ventilated area. Avoid strong oxidizing agents.

Spill and Accident Procedure

Chemical Spill Dial 9-911 from campus phone or 415-476-1414 from cell phone or 415-206-8522 (SFGH only)

Spill – Assess the extent of danger. Assist contaminated or injured persons. Evacuate the spill area. Avoid breathing vapors. If possible, confine the spill to a small area using a spill kit or absorbent material. Keep others from entering contaminated area (e.g., use caution tape, barriers, etc.).

Small (<1 L) – If you have training, you may assist in the clean-up effort. Use appropriate personal protective equipment and clean-up material for chemical spilled. Double bag spill waste in clear plastic bags, label and take to the next chemical waste pick-up.

Large (>1 L) – Dial 9-911 from campus phone or 415-476-1414 from cell phone or 415-206-8522 (SFGH only) for assistance.

Chemical Spill on Body or Clothes – Remove clothing and rinse body thoroughly in emergency shower for at least 15 minutes. If discomfort persists, proceed to the Emergency Department.  If no further discomfort is experienced, have the SDS ready and contact Poison Control Hotline at 1-800-222-1222 for further exposure information. Notify your direct supervisor and EH&S at 415-476-1300 during work hours, or 9-911 during non-working hours and weekends.

Chemical Splash Into Eyes – Immediately rinse eyeball and inner surface of eyelid with water for 15 minutes by forcibly holding the eye open. If discomfort persists, proceed to the Emergency Department.  If no further discomfort is experienced, have the SDS ready and contact Poison Control Hotline at 1-800-222-1222 for further exposure information. Notify your direct supervisor and EH&S at 415-476-1300 during work hours, or 9-911 during non-working hours and weekends.

Medical Emergency Dial 9-911 (campus phone) or 476-6911 (cell phone)

Note: All serious injuries must be reported to EH&S at 415-476-1300 within 8 hours.

Non-Life Threatening Emergency– Go to Occupational Health Programs (OHP) Clinic, 415-885-7580, 2330 Post Street, Suite 460 Hours of Operation for Appointments: Monday - Friday 7:30 a.m. - 4:00 p.m. (except Holidays).

Note: All serious injuries must be reported to EH&S at 415-476-1300 within 8 hours.

Needle stick/puncture exposure (as applicable to chemical handling procedure) – Wash the affected area with antiseptic soap and warm water for 15 minutes. For mucous membrane exposure, flush the affected area for 15 minutes using an eyewash station. Page the needle stick nurse by dialing 415-353-7842 (STIC).

Decontamination/Waste Disposal Procedure

Clean contaminated surfaces with soap and water and paper towels. Dispose of the paper towels as hazardous waste.
