Type of SOP: Process Hazardous Chemical Hazardous Class
Physical & Chemical Properties/Definition of Chemical Group
CAS#: 17702-41-9
Class: Highly flammable and toxic
Molecular formula: B10H14
Form (Physical State): White crystals
Melting Point: 99.6 °C
Boiling Point: 213 °C
Density: 0.94 g/cm3
Potential Hazards/Toxicity
LD50 rat: 64 mg/kg
Potential Health Effects:
Exposure can cause restlessness, headaches, fatigue, clumsiness, nausea, hiccups and shaking. High levels can cause muscle twitches, convulsions, unconsciousness, and death. Contact can cause severe eye burns, leading to permanent damage. It may also irritate the skin, causing a rash or burning feeling on contact. Exposure to the vapor can irritate the eyes, nose, and throat.
Engineering Controls
· Facilities storing or utilizing this material should be equipped with an eyewash facility and a safety shower.
· Use only in a chemical fume hood.
Personal Protective Equipment (PPE)
· Eyes: Wear safety glasses.
· Skin: Wear nitrile, natural rubber, neoprene, butyl, PVC or Viton gloves.
· Clothing: Wear long pants, shirt, and closed toe shoes and a lab coat while handling.
· Respirators: 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/)
Hygiene Measures
· Avoid contact with skin, eyes and clothing. Wash hands before breaks and immediately after handling.
First Aid Procedures
· Inhalation: If inhaled, remove to fresh air. If not breathing give artificial respiration. If breathing is difficult, give oxygen.
· Skin Contact: Immediately flush skin with plenty of water for at least 15 minutes while removing contaminated clothing and shoes.
· Eye Contact: Remove from exposure. Immediately flush eyes with plenty of water for at least 15 minutes, holding eyes open.
· Ingestion: If swallowed, wash out mouth with water provided person is conscious. Call a physician.
Special Handling and Storage Requirements
Precautions: Do not breathe dust. Do not get in eyes, on skin, on clothing. Avoid prolonged or repeated exposure.
Storage: Decaborane must be stored to avoid contact with OXIDIZERS, such as PERMANGANATES, NITRATES, PEROXIDES, CHLORATES, and PERCHLORATES; or HALOGENATED COMPOUNDS, since violent reactions occur. Store in tightly closed containers in a cool, well-ventilated area away from heat and water. Heat can cause an explosion. Contact with water can slowly produce flammable Hydrogen gas. Detached storage is preferable. Sources of ignition such as smoking and open flames are prohibited where decaborane is handled, used, or stored.
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.
