===============================================================================

FLASH POINT               Not applicable

(test method(s)):



FLAMMABLE LIMITS IN AIR,      LOWER:   Not applicable

% by volume:                  UPPER:   Not applicable



EXTINGUISHING MEDIA:          Apply alcohol-type or all-purpose-type foams by

                              manufacturer's recommended techniques for large

                              fires. Use CO2 or dry chemical media for small

                              fires.



SPECIAL FIRE FIGHTING         Do not direct a solid stream of water or foam

PROCEDURES:                   into burning molten material; this may cause

                              spattering and spread the fire. Use self-

                              contained breathing apparatus and body-covering

                              protective clothing.



UNUSUAL FIRE AND              Avoid dispersion of dust in air to reduce

EXPLOSION HAZARDS:            potential for dust explosions.

===============================================================================

TLV AND SOURCE:

          10 ppm, 20 ppm STEL for vinyl acetate, ACGIH 1987-88

-------------------------------------------------------------------------------

EFFECTS OF SINGLE OVEREXPOSURE:

-------------------------------

SWALLOWING:                   No evidence of adverse effects from available

                              information.



SKIN ABSORPTION:              No evidence of adverse effects from available

                              information.



INHALATION:                   May cause irritation of the eyes and upper

                              respiratory tract.



SKIN CONTACT:                 No evidence of adverse effects from available

                              information.



EYE CONTACT:                  Vapors and liquid may cause minimal irritation.

-------------------------------------------------------------------------------

EFFECTS OF REPEATED OVEREXPOSURE:

          This product contains residual vinyl acetate monomer. Repeated

          exposure to high concentrations of vinyl acetate vapors

          (approximately 200 ppm and greater) produced evidence of respiratory

          tract irritation in laboratory animals.



MEDICAL CONDITIONS AGGRAVATED BY OVEREXPOSURE:

          A knowledge of the available toxicology information and of the

          physical and chemical properties of the material suggests that

          overexposure is unlikely to aggravate existing medical conditions.



SIGNIFICANT LABORATORY DATA WITH POSSIBLE RELEVANCE TO HUMAN

HEALTH HAZARD EVALUATION:

          Life-time exposure to high vapor concentrations (600 ppm) of vinyl

          acetate caused tumors of the respiratory tract of laboratory animals;

          this response possibly being associated with the irritant effect. No

          carcinogenic effects were observed when laboratory animals received

          vinyl acetate in drinking water (up to 0.5%) with exposure taking

          place from the period of embryofetal development and continuing

          throughout a major portion of their life span. There is no evidence

          that vinyl acetate has caused cancer in humans. There should be

          minimal risk when used with ventilation adequate to keep the

          atmospheric concentration of vinyl acetate below the recommended

          exposure limit. Male rats receiving vinyl acetate at high

          concentrations in drinking water (0.5%) for two generations possibly

          demonstrated a decreased ability to produce offspring.



OTHER EFFECTS OF OVEREXPOSURE:

          None currently known.

-------------------------------------------------------------------------------

EMERGENCY AND FIRST AID PROCEDURES:

-----------------------------------

SWALLOWING:                    No harmful effects expected.



SKIN:                         Wash skin with soap and water.

INHALATION:                        Remove to fresh air.



EYES:                              Flush thoroughly with water. Seek medical

                                   attention if irritation persists.



NOTES TO PHYSICIAN:           Toxicology studies have shown similar materials

                              to be of very low acute toxicity and non-

                              irritant. There is no specific antidote.

                              Treatment of overexposure should be directed at

                              the control of symptoms and the clinical

                              condition.
