                            50-00-0       < 0.1%    formaldehyde

NFPA Rating:  Not known

Section 3: Hazard Identification

Emergency overview:
                  This material is not hazardous by OSHA Hazard Communication 

Physical Health Hazards:
                  None known.

Physical state:   Solid

Color:            White to light yellow colored, free flowing powder

Odor:             Slightly pungent

Odor threshold:   No data available

Toxicity Data:
                 Oral LD50 (Rat) >5.010 mg/kg - practically nontoxic
                 Dermal LD50 (Rabbit) >2.000 mg/kg - nor more than slightly toxic

Irritation Data:
  Eye (Rabbit):  3.3 on a scale of 110.0 - slightly irritating
  Skin (Rabbit): 0.0 on a scale of 8.0 - non-irritating

Potential Health Effects:

Routes of exposure:
                 Inhalation, Ingestion, Skin Contact

Signs and Symptoms of Acute Exposure:
            Not known.  Animals subjected to long term exposure to polyvinyl 
            alcohol under the skin showed no increase in tumor formation where 
            a powdered form was used.  However, an increase in tumors was reported 
            in similar studies where polyvinyl alcohol sponges were implanted 
            (IARC Monographs 19:351-359).  NIOSH registry of toxic effects of 
            chemical substances reported polyvinyl alcohol as "animal positive" 
            for carcinogenicity.  Although the sponge form of polyvinyl alcohol has 
            caused fibrosis in humans, the information is not considered relevant to 
            normal workplace exposure to polyvinyl alcohol resins and therefore, 
            these resins are not considered to pose a carcinogenic risk to a worker.

Skin contact:
                 May be irritating.

                 May be harmful

Eye contact:
                 Mechanical irritation is possible, therefore the dust form of the 
                 material should be kept from contacting the eyes.

                 May be harmful.  

Chronic Health Effects Summary:
                 No known chronic health effects.

Conditions Aggravated by Exposure:
                No known conditions are aggravated by this material.  However, there 
                is a dust-explosion potential present with the use of this material, 
                especially when working with larger (than laboratory) quantities.

Section 4: First Aid Measures

Handle in accordance with good industrial hygiene and safety practices.
These practices include avoiding unnecessary exposure and removal of the
material from eyes, skin and clothing.

     If symptoms are experienced, move victim to fresh
     air, if symptoms persist, obtain medical attention.

Eye Contact: 
     Wash eyes with clean low-pressure water.  If 
     irritation persists, seek medical advice.

Skin Contact: 
     If powdered or dust form of the material contacts the skin, 
     immediately flush the skin with large amounts of water. If 
     irritation or other symptoms persist, seek medical attention.

     Adverse health effects due to ingestion are not
     anticipated.  If gastric irritation or discomfort
     persists, seek medical advice.

Section 5: Fire Fighting Measures


NFPA Rating:  Not known

Flammability classification:  Not classified.  

Flash Point/Method:  Not applicable

Auto-Ignition Temperature:  Not known

Flammable Limits:  
     Lower:  Not applicable
     Upper:  Not applicable

Hazardous Combustion/Decomposition Products:
     Carbon monoxide, carbon dioxide, formaldehyde, acetic acid,  
     acrolein (trace) may be formed.

Special Conditions to Avoid:
     Dust particles in the atmosphere of this material may be explosive.
     Keep away from heat, sparks, flame and all other ignition sources.  
     Keep containers or bags tightly closed. Clean up all dust 
     accumulations.  Prevent dust accumulations and dust clouds, 
     possibly using water to "wet" dry dust from forming a cloud.

Extinguishing Media:
     Water spray or any Class A extinguishing agent.

Fire Fighting Instructions:
     Protective Equipment/Clothing:  Wear a NIOSH approved positive
     pressure self-contained breathing apparatus and firefighter
     turnout gear.  There could be the evolution of toxic products of 
     combustion. Firefighting equipment should be fully decontaminated 
     after use.

     Use flooding quantities of water until well after fire is out.

Unusual fire and explosion hazards: 
     Dust when mixed in sufficient quantities with air creates a 
     potential for explosive concentrations.

Section 6: Accidental Release Measures


Release response:

     Vacuum or otherwise pick up and retain for recycle or disposal.  
     Do not flush spilled material to the sewer or the environment.  
     Avoid creating a dust cloud since this could create an a potential 
     for a dust explosion hazard.  Use vacuum equipment designed especially 
     for handling combustible dust.


Reportable Quantities:

    See Section 15: Regulatory information.

Section 7: Handling and Storage

   Handle in accordance with good industrial hygiene and safety practices.
   These practices include avoiding unnecessary exposure and removal of the
   material from eyes, skin and clothing. 

   Keep container dry. Store away from excessive heat, sparks and flame.
   Avoid creating any dust cloud when handling.  Keep container close
   to prevent contamination.

Section 8: Exposure Controls and Personal Protection

Engineering Controls: 

   Provide sufficient ventilation to minimize exposure. Use local mechanical
   exhaust ventilation at sources of air contamination such as open process

Personal Protection:

   Inhalation: Avoid breathing dust. Use NIOSH/OSHA approved equipment when
   airborne exposure is excessive. High airborne concentrations may require
   use of self-contained breathing apparatus or supplied air respirator.
   Respiratory protection programs must be in compliance with 29 CFR


   Skin contamination should be minimized as good industrial practice.  
   Wearing of protective gloves is recommended.  Wash hands and 
   contaminated skin after handling.

   Always use safety glasses, even for work with small 
   quantities, such as the making Formvar filmed grids.
