SECTION 3 - HAZARDS IDENTIFICATION
EMERGENCY OVERVIEW
Appearance: colorless clear liquid. Flash Point: -11 deg C.
Danger! Highly flammable. Causes eye and respiratory tract irritation.
May form explosive peroxides.
Target Organs: Respiratory system, eyes.
Potential Health Effects
Eye: Causes eye irritation.
Skin: May cause skin irritation. May be harmful if absorbed through the
skin.
Ingestion: May cause irritation of the digestive tract. May be harmful if
swallowed.
Inhalation: Causes respiratory tract irritation. May be harmful if inhaled.
Chronic: Prolonged or repeated exposure may cause permanent eye
damage. Prolonged or repeated exposure may cause nausea, dizziness,
and headache.
SECTION 4 - FIRST AID MEASURES
Eyes: Get medical aid immediately. Immediately flush eyes with plenty of
wa ter for at least 15 minutes.
Skin: Get medical aid. Immediately flush skin with plenty of water for at
least 15 minutes while removing contaminated clothing and shoes.
Ingestion: Get medical aid immediately. Do NOT induce vomiting. If
conscious and alert, rinse mouth and drink 2-4 cupfuls of milk or water.

apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent),
and full protective gear. Will burn if involved in a fire. Flammable Liquid.
Can release vapors that form explosive mixtures at temperatures above
the flashpoint. Vapor may cause flash fire. May form explosive peroxides.
Extinguishing Media: Use water spray to cool fire-exposed containers.
Use foam, dry chemical, or carbon dioxide. Water may be ineffective.

SECTION 6 - ACCIDENTAL RELEASE MEASURES
General Information: Use proper personal protective equipment as
indicated in Section 8.
Spills/Leaks: Absorb spill with inert material (e.g. vermiculite, sand or
earth), then place in suitable container. Remove all sources of ignition.
Use a spark-proof tool. Provide ventilation. Do not let this chemical enter
the environment.
SECTION 7 - HANDLING AND STORAGE
Handling: Ground and bond containers when transferring material. Use
spark-proof tools and explosion proof equipment. Avoid contact with eyes,
skin, and clothing. Keep away from heat, sparks and flame. Avoid
ingestion and inhalation. Use with adequate ventilation.
Storage: Keep away from sources of ignition. Store in a cool, dry place.
Store in a tightly closed container. Flammables-area.
SECTION 8 - EXPOSURE CONTROLS, PERSONAL PROTECTION
Engineering Controls: Facilities storing or utilizing this material should
be equipped with an eyewash facility and a safety shower. Use adequate
general or local explosion-proof ventilation to keep airborne levels to
acceptable levels.
