 **** SECTION 3 - HAZARDS IDENTIFICATION ****
 
 EMERGENCY OVERVIEW
 Highly flammable. May form explosive peroxides.Highly flammable.
 
 Potential Health Effects
 Eye:
 May cause eye irritation.  The toxicological properties of this
 material have not been fully investigated.
 Skin:
 May cause skin irritation. The toxicological properties of this
 material have not been fully investigated.
 Ingestion:
 May cause gastrointestinal irritation with nausea, vomiting and
 diarrhea. The toxicological properties of this substance have not
 been fully investigated.
 Inhalation:
 May cause respiratory tract irritation. The toxicological properties
 of this substance have not been fully investigated. Vapors may cause
 dizziness or suffocation.
 Chronic:
 No information found.
 
 **** SECTION 4 - FIRST AID MEASURES ****
 
 Eyes:
 Flush eyes with plenty of water for at least 15 minutes,
 occasionally lifting the upper and lower eyelids. Get medical aid.
 Skin:
 Get medical aid. Immediately flush skin with plenty of water for at
 least 15 minutes while removing contaminated clothing and shoes.
 Wash clothing before reuse.
 Ingestion:
 Never give anything by mouth to an unconscious person. Get medical
 aid. Do NOT induce vomiting. If conscious and alert, rinse mouth and
 drink 2-4 cupfuls of milk or water.
 Inhalation:
 Remove from exposure and move to fresh air immediately. 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:
 As in any fire, wear a self-contained breathing apparatus in
 pressure-demand, MSHA/NIOSH (approved or equivalent), and full
 protective gear. Vapors may form an explosive mixture with air.
 Vapors can travel to a source of ignition and flash back. During a
 fire, irritating and highly toxic gases may be generated by thermal
 decomposition or combustion. Use water spray to keep fire-exposed
 containers cool. Containers may explode in the heat of a fire.
 Flammable liquid and vapor. Vapors may be heavier than air.  They
 can spread along the ground and collect in low or confined areas.
 Will be easily ignited by heat, sparks or flame.
 Extinguishing Media:
 For small fires, use dry chemical, carbon dioxide, water spray or
 alcohol-resistant foam. For large fires, use water spray, fog, or
 alcohol-resistant foam. Do NOT use water directly on fire. Use water
 spray to cool fire-exposed containers. Water may be ineffective. Do
 NOT use straight streams of water.
 
 **** 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. Clean up spills immediately,
 observing precautions in the Protective Equipment section. Remove all
 sources of ignition. Use a spark-proof tool. Provide ventilation. A
 vapor suppressing foam may be used to reduce vapors.
 
 **** SECTION 7 - HANDLING and STORAGE ****
 
 Handling:
 Wash thoroughly after handling. Use with adequate ventilation.
 Ground and bond containers when transferring material. Avoid contact
 with eyes, skin, and clothing. Empty containers retain product
 residue, (liquid and/or vapor), and can be dangerous. Keep container
 tightly closed. Keep away from heat, sparks and flame. Avoid
 ingestion and inhalation. Do not pressurize, cut, weld, braze,
 solder, drill, grind, or expose empty containers to heat, sparks or
 open flames.
 Storage:
 Keep away from heat, sparks, and flame. Keep away from sources of
 ignition. Store in a tightly closed container. Store in a cool, dry,
 well-ventilated area away from incompatible substances.
 Refrigerator/flammables.
 
 **** SECTION 8 - EXPOSURE CONTROLS, PERSONAL PROTECTION ****
 
 Engineering Controls:
 Use adequate ventilation to keep airborne concentrations low.
 Exposure Limits
 CAS# 1191-99-7:
 
 
 Personal Protective Equipment
 
 Eyes:
 Wear appropriate protective eyeglasses or chemical
 safety goggles as described by OSHA's eye and face
 protection regulations in 29 CFR 1910.133 or European
 Standard EN166.
 Skin:
 Wear appropriate protective 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.
