Section 3 - HAZARDS IDENTIFICATION
  EMERGENCY OVERVIEW
Very toxic by inhalation and in contact with skin.Air sensitive.Lachrymator (substance which increases the flow of tears).
Potential Health Effects
Eye:
May cause eye irritation. Lachrymator (substance which increases the flow of tears).
Skin:
May cause skin irritation.
Ingestion:
Harmful if swallowed. May cause liver damage. May cause digestive tract disturbances. Effects may be delayed.
Inhalation:
Effects may be delayed. May cause respiratory tract irritation.
Inhalation may produce coughing, nausea, and pulmonary edema.
Chronic:
Chronic ingestion may cause liver damage. Repeated exposure may cause central nervous system damage.

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.
Skin:
Get medical aid. 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. Do NOT induce vomiting. If conscious and alert, rinse mouth and drink 2-4 cupfuls of milk or water.
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. Do NOT use mouth-to-mouth resuscitation.
Notes to Physician:
Treat symptomatically and supportively.

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. Combustion generates toxic fumes. During a fire, irritating and highly toxic gases may be generated by thermal decomposition or combustion. Substance is noncombustible. Containers may explode in the heat of a fire. Vapors may be heavier than air.
They can spread along the ground and collect in low or confined areas.
Extinguishing Media:
Substance is noncombustible; use agent most appropriate to extinguish surrounding fire. Do NOT get water inside containers. Do NOT use straight streams of water. For small fires, use dry chemical, carbon dioxide, or water spray. For large fires, use water spray, fog or regular foam. Cool containers with flooding quantities of water until well after fire is out.

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. Avoid runoff into storm sewers and ditches which lead to waterways. Provide ventilation. Do not get water inside containers.

Section 7 - HANDLING and STORAGE
  Handling:
Wash thoroughly after handling. Wash hands before eating. Avoid breathing dust, vapor, mist, or gas. Keep container tightly closed.
Handle under an inert atmosphere. Store protected from air. Avoid mechanical shock and friction.
Storage:
Do not store in direct sunlight. Keep containers tightly closed. Do not expose to air. Store under an inert atmosphere.

Section 8 - EXPOSURE CONTROLS, PERSONAL PROTECTION
  Engineering Controls:
Use adequate general or local exhaust ventilation to keep airborne concentrations below the permissible exposure limits.
Exposure Limits CAS# 79-34-5: United States OSHA: 5 ppm TWA; 35 mg/m3 TWA Belgium - TWA: 1 ppm VLE; 7 mg/m3 VLE France - VME: 1 ppm VME; 7 mg/m3 VME France - VLE: 5 ppm VLE; 35 mg/m3 VLE Germany: 1 ppm TWA; 7 mg/m3 TWA Germany: Skin absorber Japan: 1 ppm OEL; 6.9 mg/m3 OEL Malaysia: 1 ppm TWA; 6.9 mg/m3 TWA Netherlands: 1 ppm MAC; 7 mg/m3 MAC Spain: 1 ppm VLA-ED; 7 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 gloves to prevent skin exposure.
Wear impervious gloves. Wear an impervious apron.
Clothing:
Wear appropriate protective clothing to minimize contact with skin. Wear an impervious apron.
Respirators:
Wear a NIOSH/MSHA or European Standard EN 149 approved full-facepiece airline respirator in the positive pressure mode with emergency escape provisions.
