Engineering Controls

Work with this chemical in a certified ducted fume hood. Facilities storing or utilizing this material should be equipped with an eyewash facility and a safety shower.

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 Wear nitrile gloves.

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

Refer to glove selection chart from the links below: http://www.ansellpro.com/download/Ansell_8thEditionChemicalResistanceGuide.pdf OR http://www.allsafetyproducts.biz/page/74172 OR http://www.showabestglove.com/site/default.aspx OR http://www.mapaglove.com/

Eye Protection ANSI approved safety glasses or goggles.

Skin and Body Protection Lab coats should be worn. These laboratory coats must be appropriately sized for the individual and be buttoned to their full length. Laboratory coat sleeves must be of a sufficient length to prevent skin exposure while wearing gloves. Full length pants and close-toed shoes must be worn at all times by all individuals that are occupying the laboratory area. The area of skin between the shoe and ankle should not be exposed.

Hygiene Measures Avoid contact with skin, eyes and clothing. Wash hands before breaks and immediately after handling the product.

First Aid Procedures

If inhaled If breathed in, 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 Rinse thoroughly with plenty of water for at least 15 minutes (using emergency eyewash) and consult a physician. Continue rinsing eyes during transport to hospital.

Special Handling and Storage Requirements

Precautions for safe handling Avoid formation of dust and aerosols. Provide appropriate exhaust ventilation at places where dust is formed. Avoid oxidizing agents. Conditions for safe storage Keep container tightly closed in a dry and well-ventilated place. Place in secondary containment. Label container, secondary containment, and storage location as “Reproductive Toxicant”.

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.
