Type of SOP: ☐ Process ☒Hazardous Chemical ☐ Hazardous Class
Purpose
Methylazoxymethanol acetate is a combustible liquid. It is toxic if ingested and may be harmful if inhaled or absorbed through the skin. It is corrosive to skin, eyes, mucous membranes, and upper respiratory tract. It is classified by IARC as Group 2B, possibly carcinogenic to humans. It is a suspected reproductive toxicant. Methylazoxymethanol acetate is a potent alkylating agent and neurotoxin used for research purposes. It is found in cycad leaves and seeds.

Potential Hazards/Toxicity
Methylazoxymethanol acetate is a combustible liquid. It is toxic if ingested and may be harmful if inhaled or absorbed through the skin. It may cause irritation to the gastrointestinal tract, respiratory tract, skin, and eyes. It is corrosive to skin, eyes, mucous membranes, and upper respiratory tract. It is classified by IARC as Group 2B, possibly carcinogenic to humans. It may cause harm to the unborn child. Symptoms of exposure include nausea, vomiting, headache, dizziness, tiredness, erythema, pneumonitis, pulmonary edema, and unconsciousness.
Engineering Controls
Chemical fume hood. Adequate exhaust and capture filtration. Electrically grounded lines and equipment.
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 methylazoxymethanol acetate.

Eye Protection
ANSI approved, tight-fitting glasses/goggles. Face shields are recommended.
Skin and Body Protection
Flame-resistant lab coat preferably made of antistatic material, 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
Immediately flush with plenty of water for at least 15 minutes while removing contaminated clothing. Consult a physician. Take victim immediately to the hospital.
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. Continue rinsing eyes during transport to the hospital.
If swallowed
Do not induce vomiting. Never give anything by mouth to an unconscious person. If victim is conscious and alert, 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. Use spark-proof tools and explosion-proof equipment. Provide adequate ventilation. Keep away from heat and other sources of ignition- No smoking. Prevent build-up of electrostatic charge.
Conditions for safe storage: Keep container tightly closed in a cool, dry, and well-ventilated area. Opened containers must be carefully resealed and kept upright to prevent leakage. Recommended storage temperature is 4 °C. Avoid strong oxidizing agents, strong acids, and strong bases.
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.
