Section 3.                    HAZARD IDENTIFICATION
Emergency Overview:
Potential Health Effects:
  INHALATION: Major route of exposure. Vapor is heavier than air and can
              cause suffocation by reducing the available oxygen for
              breathing. Breathing high concentrations of vapor may cause
              light-headedness, giddiness, shortness of breath, confusion,
              and may lead to narcosis, cardiac irregularities,
              or unconsciousness. Inhalation of high concentrations in
              a closely confined area may be fatal.

  EYES: Liquid contact may irritate eyes.


  SKIN: Not a corrosive however, repeated or prolonged exposure may irritate
        skin.

  INGESTION: No specific intervention is indicated as the compound is not
             likely to be hazardous by ingestion. Consult a physician if
             necessary. Do not induce vomiting because the hazard of aspirating
             the material into the lungs is considered greater than swallowing
             it.

================================================================================
Section 4.                    FIRST AID MEASURES
     Inhalation:
          Move to fresh air in case of accidental inhalation of vapors.  If
          victim has stopped breathing, give artificial respiration.  Call for
          prompt medical attention.

     Eye Contact:
          Flush eyes with large amounts of water for 15 minutes or until
          irritation subsides.  If irritation persists, get medical attention.

     Skin Contact:
          Remove contaminated clothing (including shoes) and wash before reuse.
          Flush with large amounts of water.  Use soap if available.  If
          irritation persists, seek medical attention.

     Ingestion:
          Do not induce vomiting unless directed by a physician.  If conscious
          and alert, give two glasses of water.  Seek medical attention
          immediately.

================================================================================
Section 6.                ACCIDENTAL RELEASE MEASURES
     LAND SPILL:
  Evacuate area. Ventilate area well and avoid breathing vapors. Vapor
  concentration will be highest along floor and in low lying areas. Pick up
  liquid on suitable absorbent and store in sealed metal containers.
  Shut off fire sources. Workers should wear proper equipment to work in
  clean up area. Unprotected personell should move upwind.

         place out of direct sunlight and away from incompatible materials.
         (See STABILITY AND REACTIVITY Section 10.)  Follow all MSD Sheet and
         Label warnings even after container is emptied.

================================================================================
Section 8.          EXPOSURE CONTROL / PERSONAL PROTECTION
     Engineering Controls:
         (X)    Local Exhaust ventilation acceptable.
         (X)    Mechanical ventilation recommended.
         ( )    Use explosion-proof ventilation equipment.
         (X)    Do not use in confined spaces without mechanical ventilation
                equipment.
         See section 2 for component exposure guidelines.

     Personal Protection:
       RESPIRATOR:
         If concentrations are over the exposure limit and are known, air
         purifying respirator with Organic Vapor Cartridges may be acceptable.
         Refer to cartridges for acceptable levels.  If concentrations are
         over exposure limit and are unknown, use a supplied air respirator.

       HAND PROTECTION:
         (X)    Gloves recommended
                (X) Solvex            (X) Neoprene
                (X) Butyl             ( ) Buna
                ( ) Natural Latex     ( ) Cotton/Jersey

       EYE PROTECTION:
         (X) Safety Glasses    ( ) Chemical Goggles    ( ) Full Face Shield

       OTHER RECOMMENDATIONS:

              Inhalation 4 hour LC50:    37,300 ppm in rats
              Oral              LD50:    > 5g/kg in rats
              Ames Essay:                Negative
              Chromosome aberration
               With CHL:                 Negative
              Unscheduled DNA Synthesis: Negative

         1,3-Dichloro-1,1,2,2,3-pentafluoropropane
              Inhalation 4 hour LC50:    36,800 ppm in rats
              Oral              LD50:    > 5g/kg in rats
              Ames Essay:                Negative
              Chromosome aberration
               With CHL:                 Negative
              Unscheduled DNA Synthesis: Negative

     Neither HCFC-225ca or HCFC-225cb causes eye irritation and dermal
  toxicity. In 28-day inhalation studies with rat, the activity and
  responsiveness of the animals was reduces at 5,000ppm or greater with each
  isomer. Toxicity was otherwise confined to the liver; liver enlargement and
  induction of peroxisomes was seen following treatment with either isomer.
  HCFC-225ca was more potent then HCFC-225cb in eliciting these liver effects.

     In 28-day study with marmoset, exposure to HCFC-225ca at 1000ppm caused
  effects on the liver, such as slight fat depositionassociated with changes in
  serum biochemical parameters. In the same study, exposure to HCFC-225cb at
  5,00ppm caused somnolence during exposure and an increase of cytochrome P-450,
  indicative an adaptive response to HCFC-225cb. However, no liver enlargement
  was seen and virtually no peroxisome induction was observed in either isomer.

     The compounds do not produce genetic damage in bacterial cell cultures or
  with CHL; however in one study withmammalian cell cultures (human lymphocytes)
  HCFC-225ca caused damage while HCFC-225cb elicited a marginal response.
