Purpose
Aspirin (also known as o-acetylsalicylic acid) is an over-the-counter medication used as an antipyretic, an
analgesic, and an anti-inflammatory drug. High doses of the drug can cause gastrointestinal ulcers, stomach
bleeding, and tinnitus. Aspirin is one of the most widely used medications in the world. Despite some of the
side effects, it has many benefits. One main benefit of using aspirin is its antiplatelet effect which can aid in
preventing heart attacks, strokes, and blood clot formation in high risk individuals.

Aspirin may be harmful if inhaled, ingested, or absorbed through the skin. Causes respiratory tract, skin, and
eye irritation. Prolonged exposure may lead to gastrointestinal ulcers, stomach bleeding, and tinnitus. It is a
suspected reproductive toxicant. Aspirin has a permissible exposure limit (PEL) of 5 mg/m 3.
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 aspirin.

Eye Protection
ANSI approved, tight-fitting safety 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. Consult a physician.
In case of skin contact
Wash off with soap and plenty of water for at least 15 minutes. Consult a physician.
In case of eye contact

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.
Non-Life Threatening Emergency– Go to Occupational Health Programs (OHP) Clinic, 415-8857580, 2330 Post Street, Suite 460 Hours of Operation for Appointments: Monday - Friday
7:30 a.m. - 4:00 p.m. (except Holidays).

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.
