Section 3 - HAZARDS IDENTIFICATION
  EMERGENCY OVERVIEW
Highly flammable. Harmful by inhalation, in contact with skin and if swallowed. Causes severe burns.
Potential Health Effects
Eye:
Causes eye burns. Vapors may cause eye irritation.
Skin:
Causes skin burns. May be absorbed through the skin in harmful amounts. Prolonged or repeated contact may dry/defat the skin and cause irritation.
Ingestion:
Causes gastrointestinal tract burns. May be harmful if swallowed.
Inhalation:
Inhalation may produce coughing, nausea, and pulmonary edema.
Chronic:
Chronic exposure may cause effects similar to those of acute exposure.

Section 4 - FIRST AID MEASURES
  Eyes: In case of contact, immediately flush eyes with plenty of water for at least 15 minutes. Get medical aid immediately.
Skin:
In case of contact, immediately flush skin with plenty of water for at least 15 minutes while removing contaminated clothing and shoes.
Get medical aid immediately. Wash clothing before reuse.
Ingestion:
If swallowed, do NOT induce vomiting. Get medical aid immediately.
If victim is fully conscious, give a cupful of water. Never give anything by mouth to an unconscious person.
Inhalation:
If inhaled, remove to fresh air. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Get medical aid.
Notes to Physician:

Section 5 - FIRE FIGHTING MEASURES
  General Information:
Use water spray to keep fire-exposed containers cool. Wear appropriate protective clothing to prevent contact with skin and eyes. Wear a self-contained breathing apparatus (SCBA) to prevent contact with thermal decomposition products. Extremely flammable liquid and vapor. Vapor may cause flash fire. Vapors are heavier than air and may travel to a source of ignition and flash back. Vapors can spread along the ground and collect in low or confined areas.
Extinguishing Media:
For small fires, use dry chemical, carbon dioxide, water spray or alcohol-resistant foam. Water may be ineffective.

Section 6 - ACCIDENTAL RELEASE MEASURES
  General Information: Use proper personal protective equipment as indicated in Section 8.
Spills/Leaks:
Absorb spill with inert material (e.g. vermiculite, sand or earth), then place in suitable container. Use water spray to dilute spill to a non-flammable mixture. Use water spray to disperse the gas/vapor.
Remove all sources of ignition. Provide ventilation. Approach spill from upwind.

Section 7 - HANDLING and STORAGE
  Handling:
Ground and bond containers when transferring material. Use spark-proof tools and explosion proof equipment. Do not get in eyes, on skin, or on clothing. Empty containers retain product residue, (liquid and/or vapor), and can be dangerous. Avoid ingestion and inhalation. Do not pressurize, cut, weld, braze, solder, drill, grind, or expose empty containers to heat, sparks or open flames. Use only with adequate ventilation. Keep away from heat, sparks and flame.
Storage:
Keep away from heat, sparks, and flame. Keep away from sources of ignition. Store in a tightly closed container. Keep from contact with oxidizing materials. Store in a cool, dry, well-ventilated area away from incompatible substances. Keep away from organic halogens.
Keep away from acids.

Section 8 - EXPOSURE CONTROLS, PERSONAL PROTECTION
  Engineering Controls:
Facilities storing or utilizing this material should be equipped with an eyewash facility and a safety shower. Use adequate general or local exhaust ventilation to keep airborne concentrations below the permissible exposure limits.
Exposure Limits CAS# 109-89-7: United Kingdom, WEL - TWA: 10 ppm TWA; 30 mg/m3 TWA United Kingdom, WEL - STEL: 25 ppm STEL; 76 mg/m3 STEL United States OSHA: 25 ppm TWA; 75 mg/m3 TWA Belgium - TWA: 5 ppm VLE; 15 mg/m3 VLE Belgium - STEL: 15 ppm VLE; 46 mg/m3 VLE France - VLE: 10 ppm VLE; 30 mg/m3 VLE Germany: 5 ppm TWA; 15 mg/m3 TWA Germany: Skin absorber Japan: 10 ppm OEL; 30 mg/m3 OEL Malaysia: 5 ppm TWA; 15 mg/m3 TWA Netherlands: 5 ppm MAC; 15 mg/m3 MAC Russia: 30 mg/m3 TWA Spain: 10 ppm VLA-ED; 30 mg/m3 VLA-ED Spain: 25 ppm VLA-EC; 75 mg/m3 VLA-EC Personal Protective Equipment Eyes: Wear chemical splash goggles and face shield.
Skin:
Wear appropriate gloves to prevent skin exposure.
Clothing:
Wear appropriate protective clothing to prevent skin exposure.
Respirators:
Follow the OSHA respirator regulations found in 29 CFR 1910.134 or European Standard EN 149. Use a NIOSH/MSHA or European Standard EN 149 approved respirator if exposure limits are exceeded or if irritation or other symptoms are experienced.
