Section 3 - HAZARDS IDENTIFICATION
  EMERGENCY OVERVIEW
Highly flammable. Harmful by inhalation and if swallowed. Limited evidence of a carcinogenic effect.Water-reactive.Carcinogen.
Potential Health Effects
Eye:
Causes eye irritation.
Skin:
Causes skin irritation. Exposure may cause irritation characterized by redness, dryness, and inflammation.
Ingestion:
May cause gastrointestinal irritation with nausea, vomiting and diarrhea. May cause respiratory failure. May cause systemic toxic effects on the heart, liver, and kidneys.
Inhalation:
Causes respiratory tract irritation. Irritation may lead to chemical pneumonitis and pulmonary edema. May cause effects similar to those described for ingestion. Causes narcotic effects including headache, dizziness, weakness, unconsciousness, and possible death.
Chronic:
Prolonged or repeated skin contact may cause irritation. Chronic inhalation and ingestion may cause effects similar to those of acute inhalation and ingestion. May cause cancer in humans.

Section 4 - FIRST AID MEASURES
  Eyes: Immediately flush eyes with plenty of water for at least 15 minutes, occasionally lifting the upper and lower eyelids. Get medical aid immediately.
Skin:
Get medical aid. Immediately flush skin with plenty of water for at least 15 minutes while removing contaminated clothing and shoes.
Ingestion:
If victim is conscious and alert, give 2-4 cupfuls of milk or water.
Never give anything by mouth to an unconscious person. Get medical aid immediately.
Inhalation:
Get medical aid immediately. Remove from exposure and move to fresh air immediately. If not breathing, give artificial respiration. If breathing is difficult, give oxygen.
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. During a fire, irritating and highly toxic gases may be generated by thermal decomposition or combustion.
Extinguishing Media:
Use carbon dioxide or dry chemical. DO NOT USE 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. Scoop up with a nonsparking tool, then place into a suitable container for disposal.

Section 7 - HANDLING and STORAGE
  Handling:
Wash thoroughly after handling. Wash hands before eating. Remove contaminated clothing and wash before reuse. Use only in a well-ventilated area. Keep away from heat, sparks and flame. Do not get on skin or in eyes. Do not ingest or inhale.
Storage:
Keep away from heat, sparks, and flame. Keep away from sources of ignition. Store in a cool, dry place. Store in a tightly closed container. Keep away from water.

Section 8 - EXPOSURE CONTROLS, PERSONAL PROTECTION
  Engineering Controls:
Use process enclosure, local exhaust ventilation, or other engineering controls to control airborne levels below recommended exposure limits.
Exposure Limits CAS# 74-96-4: United States OSHA: 200 ppm TWA; 890 mg/m3 TWA Belgium - TWA: 5 ppm VLE; 22 mg/m3 VLE France - VME: 200 ppm VME; 890 mg/m3 VME Malaysia: 5 ppm TWA; 22 mg/m3 TWA Netherlands: 5 ppm MAC; 22 mg/m3 MAC Russia: 5 mg/m3 TWA Spain: 5 ppm VLA-ED; 23 mg/m3 VLA-ED 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.
