Clobetasol propionate may be harmful if ingested, inhaled, or absorbed through the skin. It causes irritation
to the respiratory tract, gastrointestinal tract, skin, and eyes. Symptoms of exposure include nausea, vomiting,
somnolence, tiredness, weakness, irritability, depression, weight loss or gain, loss of appetite, muscle cramps,
hair loss or growth, eye problems, irregular heart beat, increased blood pressure, and hypoglycemia. It may
cause birth defects or other reproductive harm.
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 clobetasol propionate.

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.
