   excitement, followed by headache, dizziness, drowsiness, and nausea. 
   Advanced stages may cause collapse, unconsciousness, coma and possible 
   death due to respiratory failure. Aspiration hazard. Aspiration of 
   material into the lungs may cause chemical pneumonitis, which may be 

   Effects of inhalation:  Inhalation of high concentrations may cause 
   central nervous system effects characterized by nausea, headache, dizziness, 
   unconsciousness and coma.  Causes respiratory tract irritation. Aspiration 
   may lead to pulmonary edema.  Vapors may cause dizziness or suffocation. May 
   cause motor incoordination and speech abnormalities. May cause liver and 
   kidney damage.  Overexposure may cause dizziness, tremors, restlessness, 
   rapid heart beat, increased blood pressure, hallucinations, acidosis,

   severe heart abnormalities.

Section 04: First Aid Measures

Emergency and first aid procedures:
    Get medical assistance for all cases of over-exposure.
       Get medical aid if irritation develops or persists.  Flush skin with 
       plenty of soap and water for at least 15 minutes, while removing 
       contaminated clothing and shoes.  Wash thoroughly before reusing.  
       Get medical aid immediately. Immediately flush  thoroughly with
       water for at least 15 minutes, occasionally lifting the upper and
       lower eyelids.  Do not allow victim to rub or keep eyes closed.

       Get medical aid immediately. Remove to fresh air immediately.
       Artificial respiration if breathing has stopped. If breathing
       is difficult, give oxygen. Do NOT use mouth-to-mouth resuscitation.
       If breathing has ceased, apply artificial respiration using oxygen
       and a suitable mechanical device such as a bag and a mask.

       Do NOT induce vomiting. If conscious and alert, give 2-4 cupfuls of
       milk or water. Never give anything by mouth to an unconscious person.
       Get medical aid immediately.

  Notes to Physician:  
       Treat symptomatically and supportively.

Section 05: Fire Fighting Measures

Flash Point....................n/a
Autoignition Temperature: . . .n/a
Explosion Limits . . . . . . . n/a
NFPA Rating: (estimated) Health: 1; Flammability: 3; Instability: 0

Fire Extinguishing Media:
  For small fires use dry chemical, CO2, or "alcohol" foam, water spray 
  to cool fire-exposed containers and disperse vapor; water on fire itself 
  may be ineffective. For large fires, use water spray, fog or alcohol-resistant 
  foam.  Do NOT use straight streams of water.  Cool containers with flooding 
  quantities of water until well after fire is out.

Firefighting Procedure:
  Wear self-contained breathing apparatus in pressure-demand, MSHA/NIOSH 
  approved or equivalent, full protective gear.

Fire and explosion hazards:
  Dangerous fire and explosion hazard. Vapors may form an explosive mixture 
  with air.  Vapor can travel distance to ignition source and flash back. 
  During a fire, thermal decomposition or combustion may generate irritating 
  and highly toxic gases.  Flammable mixture. Can release vapors that form 
  explosive mixtures with air.  Hot organic chemical vapors or mists are 
  susceptible to sudden spontaneous combustion when mixed with air. Material 
  is lighter than water and a fire may be spread by the use of water. 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.

Section 06: Accidental Release Measures

Spill Response:
  General Information: Wear suitable protective equipment listed under 
  exposure/personal protection, including self contained breathing apparatus. 
  Spills/Leaks: Avoid runoff into storm sewers and ditches which lead to 
  waterways.  Avoid all sources of ignition. Absorb spill with an absorbent, 
  non-combustible material such as earth, sand or vermiculite and place in 
  suitable container for proper disposal, using a spark-proof tool.  A vapor 
  suppressing foam may be used to reduce vapors, but may not prevent ignition 
  in closed spaces. 

Section 07: Handling and Storage

Use only in a well-ventilated area.  Wash thoroughly after handling.  Remove
contaminated clothing and wash before reuse.  Avoid contact with eyes, skin
and clothing.  Ground and bond containers when transferring material.  Use
spark-proof tools and explosion proof equipment.  Avoid contact with heat,
sparks and flame.  Empty containers may contain residue - do not pressurize,
or expose empty containers to heat, sparks or open flames.  Do not take
internally.  Eye wash and safety equipment should be readily available.

Keep away from sources of ignition.  Keep away from heat, sparks, and flame.  
Store in a tightly closed container.  Store in a flammables area, away from 
incompatible materials.  Store in cool, dry, well ventilated area.

Section 08: Exposure Controls and Personal Protection

An eyewash facility and a safety shower should be available.  Use adequate
general or local exhaust ventilation to keep airborne concentrations below
the permissible exposure limits.
