Section 3: Hazards Identification


Emergency overview:

       This material is not hazardous by OSHA Hazard Communication 
       Definition

Signal Word

       CAUTION!

Physical Health Hazards:

       Dust may form explosive mixtures with air.  Molten Parafilm may
       cause thermal burns. Irritating fumes may be produced at elevated
       temperatures.

Physical state:  Solid

Color:  Translucent to white

Odor:  Faint, mild hydrocarbon odor

Odor threshold:  No data available


Potential Health Effects:

Routes of exposure:

           Ingestion, skin contact

Signs and Symptoms of Acute Exposure:

           Molten product may cause thermal burns.  At elevated temperatures,
           irritating fumes may cause soreness in the nose and throat, coughing
           may result.  

Skin contact:

           Molten product may cause thermal burns

Inhalation:

           At elevated temperatures irritating fumes may be produced.
           Inhalation of such fumes may cause soreness in the nose
           and throat and coughing.  Inhaling Parafilm dust is
           considered a nuisance.

Eye contact:

           Mechanical irritation is possible if abraided into a dust form.

Ingestion:

           Ingestion is unlikely

Chronic Health Effects Summary:

           No known chronic health effects.

Polyethylene Homopolymer:

Conditions Aggravated by Exposure:

           No known conditions are aggravated by this material.


Section 4: First Aid Measures


Take proper precautions to ensure your own health and safety before
attempting to rescue and providing first aid.  For specific information
refer to the Emergency Overview in Section of this MSDS.

Inhalation:  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 molten material contacts the skin, immediately
               flush the skin with large amounts of water to cool
               the affected tissue and polymer.  Do not attempt to
               peel the Parafilm wax from skin. Get medical attention
               immediately.

Ingestion:     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:  Health:  0   Fire:  1   Reactivity:  0

Flammability classification:

         The Parafilm wax will burn just like a candle wax.  It will ignite
         by any open flame.

Flash Point/Method:   Not applicable

Auto-Ignition Temperature:  Not known

Flammable Limits:  Lower:   Not applicable
                   Upper:   Not applicable

Hazardous Combustion Products:

         Carbon monoxide, olefinic and paraffinic compounds, trace amounts
         of organic acids, ketones, aldehydes and alcohols may be formed.

Special Conditions to Avoid:

         Polyolefin dust particles in the atmosphere are combustible and
         may be explosive.  Keep away from heat, sparks, flame and all
         other ignition sources.  If the product is abraided, clean up dust
         accumulations.  Prevent dust accumulations and dust clouds,
         

Extinguishing Media:

          Small fires:  Use dry chemicals, CO2, water spray.

          Large fires:  Use dry chemicals, CO2, water spray.

Fire Fighting Instructions:

          Protective Equipment/Clothing:  Wear a NIOSH approved positive
          pressure self-contained breathing apparatus and firefighter
          turnout gear.

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


Section 6: Accidental Release Measures


Release response:

              Pick up and retain for recycle or disposal.  

Reportable Quantities:  See Section 15: Regulatory information.




Section 7: Handling and Storage



Handling:  No particular precautions needed.

Storage:   Keep container dry.  Store away from excessive heat and away from
strong oxidizing agents. Keep container closed to prevent contamination.   Maximum
shelf life without deterioration is three years if stored between 7°C and
32°C and 50% relative humidity.


Section 8: Exposure Controls and Personal Protection


Engineering Controls:  If user operations generate dust or fumes,
ventilate area to prevent accumulation.  For the normal use in a laboratory
environment, we would not anticipate any dust being formed.

Personal Protection:

Inhalation:  None needed except in the case where dust is being
generated, in which case, use appropriate respiratory protection where
atmosphere exceeds recommended limits (for polyolefins).

Total Dust (PNOC):  ACGIH 10mg/M3, OSHA 15 mg/M3.
Respirable Dust(PNOC) ACGIH 3 mg/M3, OSHA 5 mg/M3.

Skin:  Protective clothing such as long sleeves or a lab coat should
be worn.  When handling heated materials, also be sure to use heat-resistant
gloves, boots and face protection.

Eye:  Always use safety glasses when working in the laboratory.



Section 9: Physical and Chemical Properties


Boiling Point/Range:  Not applicable

pH:                   Not applicable

Vapor Pressure:       Not applicable

Viscosity:            Not applicable

Specific Gravity:
    Solid/Liquid      Not known  
           Vapor      Not applicable

Section 10: Stability and Reactivity



Chemical Stability:  The product is stable

Conditions to Avoid:  Avoid contact with strong oxidizers,
excessive heat, sparks or open flame or dust accumulation.

Incompatibility with:  Chlorine, fuming nitric acid and strong oxidizing agents.

Hazardous Products of Deposition:  Not expected to decompose under
normal conditions.

Reactions with Air and Water:  Does not react with air, water or other
common materials.




Section 11: Toxicological Information


Summary:  Not considered to be toxic to humans or animals

Skin Effects:  No skin effects are expected from Parafilm contact.

Acute Oral Effects:  Not known

Acute Inhalation Effects:  Rats inhaling polyethylene dust developed
mild inflammatory changes in the lungs.  Prolonged inhalation of thermal
degradation products from polyethylene caused neurological effects in rats. 
We would expect that inhalation of Parafilm dust could have similar effects.

Subchronic Effects:  For polyethyelen, subchronic, 50-90 day, feeding
studies conducted on rats, dogs, and swine showed no effects from dietary
levels of 1 to 20% powdered and shredded polyethylene.  IARC has listed
polyethylene as a Group 3 substance  (not classifiable as to carcinogenicity
to humans).  Although Parafilm is not polyethylene, we believe it is sufficiently
close in composition that one could infer similar effects.

Chronic Effects/Carcinogenicity:
          None expected

Reproductive/Development Effects:
          No reproductive or developmental effects are expected.


Section 12: Ecological Information


Exotoxicity:  Exotoxicity is expected to be low based on the low water
              solubility of polymers.

Environmental Fate:  No information found in our selected references.

Bioaccumulation:  Not expected to occur.


Section 13: Disposal Considerations



This material is NOT classified as a hazardous material by RCRA.  Use only
licensed transporters and permitted disposal facilities and conform to all
laws.

Recycle to process, if possible.
