Potential Hazards/Toxicity

Tamoxifen has been classified as carcinogenic to humans by IARC and NTP.

LD50 Oral: 4100 mg/kg [Rat]

Although little data is available, tamoxifen may be harmful if inhaled, swallowed, or absorbed through the skin. It can cause irritation of the skin, eye, and respiratory tract.

Toxic Effects: Tamoxifen is a toxic substance.

Acute Effects: Hazardous in case of skin contact (irritant), of eye contact (irritant), of

ingestion, of inhalation.

Chronic Effects: CARCINOGENIC EFFECTS: Not available. MUTAGENIC EFFECTS:

Not available. TERATOGENIC EFFECTS: Not available

DEVELOPMENTAL TOXICITY: Classified Reproductive

system/toxin/female, Development toxin [POSSIBLE]. Repeated or

prolonged exposure is not known to aggravate medical conditions.

Personal Protective Equipment (PPE)

Wear double nitrile gloves, full-length lab coat, and safety glasses/face shield in addition to long pants and closed-toe shoes.

Always wash hands after removing gloves following handling tamoxifen.

Engineering Controls

Always handle tamoxifen inside a certified chemical fume hood or a ducted biosafety cabinet.

First Aid Procedures

Skin & Eye Exposure: Minor skin contact requires washing with water. Soaking or flushing contaminated areas of the skin with water for periods up to 15 minutes is required if a large area comes into contact with the chemical, or if prolonged contact occurs. Contaminated clothing may hold the chemicals in contact with the skin without being immediately noticed so remove clothing immediately and wash thoroughly before use.

In the event of eye contact, the eye should be immediately be flushed with water. If the chemical is very irritating, it is likely that the affected individual will require assistance to hold the eye open during the flushing.

Ingestion: DO NOT induce vomiting, give milk, activated charcoal or water if conscious, and get medical attention immediately.

Inhalation: Remove rapidly to clean air. Administer rescue breathing if necessary and call emergency services. Seek medical attention if needed.

Special Handling and Storage Requirements

Designated Areas

· The chemical solid or solutions will be made in chemical fume hoods and will be stored in clearly marked containers. Tamoxifen liquid solutions (10 mg/ml dissolved in corn oil) will be stored at room temperature in clearly marked secondary containers. Liquid waste will be collected for disposal by EH&S.

· All chemicals containing tamoxifen must be secondarily contained with proper signage.

· Signage is required for the container, designated work area and storage location. Sign wording must state the following:

“DANGER, CANCER HAZARD, CARCINOGEN”

Spill and Accident Procedure

Chemical Spill Dial 911 and x59797

Spill – Help contaminated or injured persons. Evacuate the spill area. Avoid breathing vapors. Eliminate sources of ignition if the chemical is flammable. 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 911 (or 310-825-1491 from cell phone) and EH&S at x59797 for assistance.

Chemical Spill on Body or Clothes – Remove clothing and rinse body thoroughly in emergency shower for at least 15 minutes. Seek medical attention. Notify supervisor and EH&S at x59797 immediately.

Chemical Splash Into Eyes – Immediately rinse eyeball and inner surface of eyelid with water for 15 minutes by forcibly holding the eye open. Seek medical attention. Notify supervisor and EH&S at x59797 immediately.

Medical Emergency Dial 911 or x52111

Life Threatening Emergency, After Hours, Weekends And Holidays – Dial 911 (or 310-825-1491 from cell phone) or contact the Ronald Reagan UCLA Medical Center (emergency room) directly at x52111 (located at 757 Westwood Plaza, enter from Gayley Avenue). Note: All serious injuries must be reported to EH&S at x59797 within 8 hours.

Non-Life Threatening Emergency– Go to the Occupational Health Facility (OHF), x56771, CHS room 67-120 (This is on the 6th floor, 7th corridor, room 120. Enter through the School of Dentistry on Tiverton Drive and proceed to the “O” elevator to the 6th floor.)Hours: M - F, 7:30 a.m. to 4:30 p.m. At all other times report to Ronald Regan UCLA Medical Center (emergency room) at x52111. Note: All serious injuries must be reported to EH&S at x59797 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 231 from a campus phone, enter 93333 when prompted and then enter your extension. Hours: M – F, 8:00 a.m. to 4:00 p.m. At all other times report to Ronald Regan UCLA Medical Center (emergency room) at x52111. Note: All needle stick/puncture exposures must be reported to EH&S at x59797 within 8 hours.

Decontamination/Waste Disposal Procedure

No waste streams containing tamoxifen shall be disposed of in sinks. Decontaminate work space with 70-75% ethanol. Wash hands and arms with soap and water after finished. Contaminated pipet tips, eppendorf tubes, and gloves should be discarded as hazardous waste according to UCLA EH&S waste disposal procedures. Excess liquid will be stored in designated and clearly marked waste containers, and will also be disposed of via EH&S.

Waste containers containing tamoxifen must be labeled:

“DANGER, CANCER HAZARD”

Material Safety Data Sheet (MSDS) Location

(State the location of MSDS)

Hardcopy or electronic copy must be available.

Online MSDS can be accessed at http://msds.ehs.ucla.edu.

Protocol/Procedure

(Add specific description of procedure.)

Note: Any deviation from this SOP requires written approval from PI.

Documentation of Training (signature of all users is required)

ü Prior to conducting any work with tamoxifen, designated personnel must provide training to his/her laboratory personnel specific to the hazards involved in working with this substance, work area decontamination, and emergency procedures.

ü The Principal Investigator must provide his/her laboratory personnel with a copy of this SOP and a copy of the tamoxifen MSDS provided by the manufacturer.

ü The Principal Investigator must ensure that his/her laboratory personnel have attended appropriate laboratory safety training or refresher training within the last two years.
