Purpose
1,3-Butadiene is an extremely flammable gas. It may be harmful if inhaled, ingested, or absorbed
through the skin. Exposure may cause irritation to the respiratory tract, skin, and eyes. It is classified by
IARC as Group 1, carcinogenic to humans. It may cause genetic defects. 1,3-Butadiene is a
cholinesterase inhibitor. Its main industrial application is in the synthesis of rubber.

Potential Hazards/Toxicity
1,3-Butadiene is an extremely flammable gas. It is air-sensitive and light-sensitive. Contents are under
pressure. It is classified by IARC as Group 1, carcinogenic to humans. It may be harmful if inhaled,
ingested, or absorbed through the skin. It may cause irritation to the respiratory tract, gastrointestinal
tract, skin, and eyes. Symptoms of exposure include heavy salivation, lachrymation, blurred vision,
involuntary defecation, diarrhea, tremor, ataxia, sweating, hypothermia, lowered heart rate, decreased
blood pressure, narcosis, headache, nausea, vomiting, dizziness, drowsiness, confusion, weakness,
muscle cramps/spasms, change in pupil size, tremors, seizures, incoordination, convulsions, and coma.
May cause birth defects or other reproductive harm. 1,3-Butadiene has a permissible exposure limit
(PEL) of 1 ppm.
Personal Protective Equipment (PPE)
Respirator Protection
Use a full-face respirator with multi-purpose combination (US) respirator cartridges.
Respirators should be used only under any of the following circumstances:
 As a last line of defense (i.e., after engineering and administrative controls have been
exhausted).
 When Permissible Exposure Limit (PEL) has exceeded or when there is a possibility that PEL
will be exceeded.
 Regulations require the use of a respirator.
 An employer requires the use of a respirator.
 There is potential for harmful exposure due to an atmospheric contaminant (in the absence of
PEL)
 As PPE in the event of a chemical spill clean-up process
Lab personnel intending to use/wear a respirator mask must be trained and fit-tested by EH&S. This is
a regulatory requirement.
Hand Protection
Handle with gloves. Fluorinated rubber and nitrile gloves are recommended.
NOTE: Consult with your preferred glove manufacturer to ensure that the gloves you plan on using are
compatible with 1,3-butadiene.

Eye Protection
 Wear chemical splash goggles and a face shield to protect from splash hazards and chemical
vapors.
Skin & Body Protection
 Fire/flame resistant lab coat, preferably made from antistatic material.
 Full-length pants
 Closed-toe rubber or leather shoes
Hygiene Measures
Avoid contact with skin, eyes, and clothing. Wash hands before breaks and immediately after
handling the product.
Engineering Controls
Chemical fume hood. Adequate exhaust and capture filtration. Electrically grounded lines and
equipment.
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
Wash skin with soap and water for at least 15 minutes while removing contaminated clothing and
shoes. Consult a physician.
In case of eye contact
Flush eyes with plenty of water for at least 15 minutes. Consult a physician.
If swallowed
Do not induce vomiting. Never give anything by mouth to an unconscious person. Rinse mouth with
water. Consult a physician.
Special Handling and Storage Requirements

1, 3-Butadiene, CAS # 106-99-0
Precautions for safe handling: Avoid contact with skin, eyes, and clothing. Avoid inhalation. Avoid
heat, flames, sparks, and other sources of ignition- No smoking. Use spark-proof tools and explosionproof equipment. Prevent build-up of electrostatic charge.
Conditions for safe storage: Keep container tightly closed in a cool, dry, and well-ventilated area.
Contents under pressure. Air-sensitive. Light-sensitive. Handle and store under inert gas. May explode
when heated. Recommended storage temperature is 2-8 °C. Avoid oxidizing agents, oxygen, copper,
copper alloys, carbides, halogens, metal oxides, and metals.
Chemical Spill
Spill – Assess the extent of danger. Help 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) – Contact EH&S for assistance at (480) 965-1823 for non-emergencies. For emergency
situations Dial 911.
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 immediately.
Chemical Splash Into Eyes – Immediately rinse eyeball and inner surface of eyelid with water from
the emergency eyewash station for 15 minutes by forcibly holding the eye open. Seek medical
attention. Notify supervisor and EH&S immediately.
Medical Emergency Dial 911
Life Threatening emergency, After Hours, Weekends and Holidays – Dial 911 or go to the nearest
emergency room.) Note: All Serious injuries must be reported to EH&S within 8 hours.
Non-Life Threatening Emergency – Go to the Occupational Health Facility (OHF). After hours go to
the nearest emergency room. Note: All serious injuries must be reported to EH&S 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 \ and then enter your
extension. After hours go to the nearest emergency room. Note: All needle stick/puncture exposures
must be reported to EH&S within 8 hours.

Decontamination/Waste Disposal Procedure
Using proper personal protective equipment as outlined above, decontaminate equipment and bench
tops using soap and water and properly dispose of all chemical and contaminated disposables as
hazardous waste following the guidelines below.
General hazardous waste disposal guidelines:
Label waste
 Attach a completed ASU Hazardous Waste tag to all waste containers as soon as the first drop
of waste is added to the container.
Store waste
 Store hazardous waste in closed containers, in secondary containment and in a designated
storage location.
 Double-bag dry waste using sealable transparent bags.
 Waste must be under the control of the person generating and disposing of it.
Dispose of waste
 Dispose of regularly generated chemical waste within 90 days.
 Use EHS Assistant online hazardous waste pick-up request system.
 Contact ASU EH&S at (480) 965-1823 with questions.
