Type of SOP: ☐ Process ☒Hazardous Chemical ☐ Hazardous Class

Purpose

Tetralin (1,2,3,4-Tetrahydronaphthalene) may form explosive peroxides, is flammable and carginogenic. This molecule is similar to the naphthalene chemical structure since except that one ring is saturated. Tetralin is produced by the catalytic hydrogenation of naphthalene.

Physical & Chemical Properties/Definition of Chemical Group

CAS#: 119-64-2

Class: Flammable, carcinogen, may form explosive peroxides

Molecular Formula: C10H12

Form (physical state): Liquid

Color: Colorless

Boiling point: 207 °C (405 °F)

Potential Hazards/Toxicity

Harmful by skin contact, eye contact, ingestion, and/or inhalation. Material causes skin irritation and is harmful if absorbed through skin. Causes eye irritation if splashed in eye. It is harmful if swallowed. It is harmful if inhaled, causing respiratory tract irritation.

Engineering Controls

Facilities storing or utilizing this material should be equipped with an eyewash facility and a safety shower. A fume hood should be used whenever possible.

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 appropriate nitrile protective gloves to prevent skin exposure.

NOTE: Consult with your preferred glove manufacturer to ensure that the gloves you plan on using are compatible with tetralin (1,2,3,4-Tetrahydronaphthalene)..

Eye Protection

Safety glasses (goggles and/or full face shield during activities which pose a splash hazard).

Skin and Body Protection

Lab coat, full length pants or equivalent, and closed toe shoes must be worn. A flame resistant/cotton lab coat must be worn when handling quantities of four liters or more.

Hygiene Measures

Avoid contact with skin, eyes and clothing. Wash hands before breaks and immediately after handling tetralin (1,2,3,4-Tetrahydronaphthalene).

First Aid Procedures

If inhaled

If breathed in, move person into fresh air. If not breathing, give artificial respiration. Get medical attention immediately.

In case of skin contact

Take off contaminated clothing and shoes immediately and flush skin with plenty of soap and water for at least 15 minutes. Wash clothing and thoroughly clean shoes before reuse. Get medical attention immediately.

In case of eye contact

Check for and remove any contact lenses. Immediately flush eyes thoroughly with plenty of water for at least 15 minutes. Cold water may be used. Get medical attention immediately.

If swallowed

Do NOT induce vomiting unless directed to do so by medical personnel. Never give anything by mouth to an unconscious person. Rinse mouth with water. Get medical attention immediately.

Special Handling and Storage Requirements

Avoid contact with skin and eyes. Avoid inhalation of vapor or mist. Use explosion-proof equipment. A fume hood should be used when handling Tetralin (1,2,3,4-Tetrahydronaphthalene). Keep away from sources of ignition and definitely no smoking. Take measures to prevent the buildup of electrostatic charge. Keep container tightly closed in a dry and well-ventilated place. Containers which are opened must be carefully resealed and kept upright to prevent leakage. Container should be dated and disposed of within one year. Reacts violently with strong oxidizers.

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.
