Purpose
Calcium phosphide is a highly flammable and toxic chemical. Contact with water or acids releases phosphine,
a toxic, flammable gas. It can be fatal if ingested and harmful if inhaled or absorbed through the skin. It may
cause respiratory tract, skin, and eye irritation. Calcium phosphide is used in fireworks, torpedos, incendiary
bombs, and pyrotechnic flares.

Contact with water releases toxic, flammable gases that may ignite spontaneously. Handle under inert gas.
Protect from moisture. Avoid water, acids, oxidizing agents, chlorine, oxygen, and sulfur. Fatal if ingested. May
be harmful if inhaled or absorbed through skin. May cause respiratory tract, skin, and eye irritation. Inorganic
phosphorus may cause stomach irritation and hemorrhages as well as liver and kidney damage.
Engineering Controls
Glove box. Handle under inert atmosphere/conditions.
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 calcium phosphide.
Refer to glove selection chart from the links below:

Eye Protection
ANSI approved, tight-fitting safety glasses/goggles. Face shields are recommended.
Skin and Body Protection
Flame resistant/cotton lab coat preferably made of antistatic material, long pants, and closed-toe shoes.
Hygiene Measures
Avoid contact with skin, eyes and clothing. Wash hands before breaks and immediately after handling the
product.
First Aid Procedures
If inhaled
Move person into fresh air. If not breathing, give artificial respiration. Consult a physician.
In case of skin contact
Wash off with soap and plenty of water. Take victim immediately to hospital. Consult a physician.
In case of eye contact
Flush eyes with water for at least 15 minutes lifting upper and lower eyelids and removing contact lenses.
Consult a physician.

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 and eyes. Avoid dust formation. Provide adequate
exhaust ventilation at places where dust is formed. Keep away from sources of ignition - No smoking.
Conditions for safe storage: Keep container tightly closed in a dry and well-ventilated place. Never allow
contact with water. Reacts violently with water. Handle and store under inert gas. Do not store with halogens,
oxidizing, and acidic materials.
Spill and Accident Procedure
Chemical Spill Dial 9-911 from campus phone or 415-476-1414 from cell phone or 415-2068522 (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 415-2068522 (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 1-800222-1222 for further exposure information. Notify your direct supervisor and EH&S at 415-4761300 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.
