4. FIRST AID MEASURES
Eye: Flush victim's eyes with large quantities of water, holding the eyelids apart. Get medical attention if irritation
persists.
Skin: Flush skin with water
Ingestion: Get prompt medical attention.
Inhalation: No adverse effects are expected, however, if irritation or other symptoms develop, remove to fresh air. Seek
medical attention if symptoms persist.
Other: Not applicable
5. FIRE FIGHTING MEASURES
Flash Point: >200掳F (93.3掳C)
Auto ignition Temperature: Not determined
Flammable Limits: LEL 2.6% UEL 12.5%
Extinguishing Media: Use water fog or spray, carbon dioxide, dry chemical or alcohol resistant foam. Do not use direct
water stream will spread fire. Cool fire exposed containers and structures with water.
Unusual Fire or Explosion Hazards: Not classified as flammable or combustible but will burn under fire conditions. A
solid stream of water directed into hot, burning liquid can cause frothing. Heat from fire may generate flammable vapor.
Fine sprays or mists may be combustible at temperatures below the normal flash point.
Special Fire-Fighting Instructions: Firefighters should wear positive pressure self-contained breathing apparatus and full
protective clothing.
Hazardous Combustion Products: Burning may produce carbon monoxide, carbon dioxide and aldehydes.
Explosion Data: (sensitivity to mechanical impact or static discharge): None known.
6. ACCIDENTAL RELEASE MEASURES
Wear appropriate protective clothing as described in Section 8. Do not flush spill to sewer. Collect using an inert absorbent
material and place in appropriate containers for disposal. Prevent spill from entering sewers and water
courses. Report releases as required by local, provincial and federal authorities.
7. HANDLING AND STORAGE
Handling: Avoid contact with the eyes. Avoid prolonged contact with skin and clothing. Avoid breathing vapors and
mists. Wash thoroughly with soap and water after handling. Keep containers closed when not in use.
Do not reuse containers. Empty containers retain product residues can be hazardous. Follow all
Storage: Store in a cool, dry, well ventilated area away from incompatible materials.
8. EXPOSURE CONTROLS/PERSONAL PROTECTION
Exposure Guidelines: Propylene glycol 50 ppm AIHA WEEL
Engineering Controls: Use with general or local exhaust ventilation to maintain exposures below the occupational
exposure limits.
Respiratory Protection: None normally needed. In operations where the occupational exposure limits are exceeded, a
NIOSH approved respirator with organic vapor/dust/mist cartridges or supplied air respirator appropriate for the form and
concentration of the contaminants should be used.
