Emergency overview:
       Material is highly volatile and flammable.  Vapors are heavier 
       than air and may travel along low areas to source of ignition.

Physical Health Hazards:
       Can cause eye irritation on contact, inhalation can cause 
       dizziness and ingestion can cause serious gastrointestinal 
       difficulties including nausea and vomiting. Skin contact can 
       cause defatting of the skin and solvents can penetrate the 
       skin in to the body.

Physical state:  


       Ketone type

Odor threshold:

refer to the Emergency Overview in Section of this MSDS.

Inhalation:   Remove to fresh air. Never give liquids to an 
                     unconscious person. Call medical assistance at once.

Eye Contact:  Wash eyes with clean low-pressure water. Seek 
                     medical advice.

Skin Contact: Wash with soap and water.

Ingestion:         Do not induce vomiting, seek medical attention
                      at once.

Section 6: Accidental Release Measures


Release response:

     Personal precautions:      
            Spilled product constitutes a slip hazard.

     Environmental precautions: 
            Try to keep liquid from getting into sewers or drainage of 

     Decontamination procedures: 
            Use absorbent materials, to soak up spilled liquid, which 
            is then placed in containers for later disposal as a 
            hazardous waste.  

  See paragraph 13 regarding disposal.

Section 7: Handling and Storage

     Wear NIOSH approved respirator is point-of-use generates vapors 
     above recommended limits.
