SECTION 3: HAZARD IDENTIFICATION
Emergency Overview: Clear, colorless liquid with a mild sweet odor. This product is flammable. Liquid will irritate eyes and skin under repeated or prolonged
exposure. Breathing high concentrations of product may produce drowsiness and a headache.
Potential Health Effects:
Eyes: Liquid and vapors of this product are irritating and can cause pain, tearing, reddening and swelling accompanied by a stinging sensation.
Skin: Contact causes skin irritation. Symptoms may include redness and burning.
Ingestion: Harmful if swallowed. Large amounts may be irritating to the mouth, throat and stomach. May cause vomiting.
Inhalation: Harmful if inhaled. High concentrations in immediate area can displace oxygen and cause dizziness, unconsciousness and even death, with longer exposure.
Keep people away from such vapors without self-contained breathing apparatus.
Preexisting Medical Conditions Aggravated by exposure: skin, eyes, liver, kidneys
SECTION 4: FIRST AID MEASURES
Eyes:
and tested by medical personnel if irritation develops or persists.
Skin: Wash skin with soap and water. Remove contaminated clothing. Get medical attention if irritation develops or persist. Wash clothing separately before reuse.
Ingestion: If swallowed, do not induce vomiting. Give lukewarm water to victim (pint) if victim is conscious and alert. Keep head below knees to minimize chance of
aspirating material into the lungs. Never give anything by mouth to an unconscious person. Get medical attention immediately.
Inhalation: Remove to fresh air. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Get medical attention.
SECTION 5: FIRE FIGHTING MEASURES
Flash Point: 102 °F (39 °C)
Extinguishing Media: Use alcohol foam, carbon dioxide or water spray when fighting fires involving this material.
Fire Fighting Instructions: As in any fire, wear self-contained breathing apparatus (pressure demand, OSHA/NIOSH approved or equivalent) and full protective gear.
SECTION 6: ACCIDENTAL RELEASE MEASURES
Large Spills: Not likely to occur.
Small Spills: Absorb spill with inert material (i.e. dry sand or earth), then place in a chemical waste container for proper disposal.
SECTION 7: HANDLING AND STORAGE
Avoid prolonged or repeated contact with skin, eyes or clothing. Wash hands before eating. Use with adequate ventilation. Avoid breathing product vapor. Do not
reuse this container. Store in a cool dry place, away from heat, sparks or flames. Keep container tightly closed when not in use. Do not store in direct sunlight.
KEEP OUT OF REACH OF CHILDREN.

*Manufacturer’s Occupational Exposure Limit (OEL)
Work/Hygienic Practices: Good general ventilation should be sufficient to control airborne levels. Local exhaust ventilation may be necessary to control any air
contaminants to within their TLVs during the use of this product. If vapor concentration exceeds TLV, use NIOSH approved organic vapor cartridge respirator. Wear
safety glasses with side shields (or goggles) and rubber or other chemically resistant gloves when handling this material.
