**** SECTION 3 - HAZARDS IDENTIFICATION ****
EMERGENCY OVERVIEW
Highly flammable. May form explosive peroxides. Harmful in contact
with skin and if swallowed. Harmful: may cause lung damage if
swallowed.
Potential Health Effects
Eye:
Causes eye irritation.
Skin:
Causes skin irritation.
Ingestion:
May cause irritation of the digestive tract. May cause central
nervous system depression, characterized by excitement, followed by
headache, dizziness, drowsiness, and nausea. Advanced stages may
cause collapse, unconsciousness, coma and possible death due to
respiratory failure. May be harmful if swallowed.
Inhalation:
Inhalation of high concentrations may cause central nervous system
effects characterized by nausea, headache, dizziness, unconsciousness
and coma. Causes respiratory tract irritation.
Chronic:
Prolonged or repeated skin contact may cause defatting and
dermatitis.
**** SECTION 4 - FIRST AID MEASURES ****
Eyes:
Flush eyes with plenty of water for at least 15 minutes,
occasionally lifting the upper and lower eyelids. Get medical aid
immediately.
Skin:
Flush skin with plenty of water for at least 15 minutes while
removing contaminated clothing and shoes. Get medical aid if
irritation develops or persists.
Ingestion:
If victim is conscious and alert, give 2-4 cupfuls of milk or water.
Never give anything by mouth to an unconscious person. Get medical
aid immediately.
Inhalation:
Remove from exposure and move to fresh air immediately. If not
breathing, give artificial respiration. If breathing is difficult,
give oxygen. Get medical aid.
Notes to Physician:
**** SECTION 5 - FIRE FIGHTING MEASURES ****
General Information:
As in any fire, wear a self-contained breathing apparatus in
pressure-demand, MSHA/NIOSH (approved or equivalent), and full
protective gear. Vapors can travel to a source of ignition and flash
back. Use water spray to keep fire-exposed containers cool. Extremely
flammable liquid and vapor. Vapor may cause flash fire. Water may be
ineffective. Material is lighter than water and a fire may be spread
by the use of water. May form explosive peroxides. Vapors may be
heavier than air. They can spread along the ground and collect in
low or confined areas. Will be easily ignited by heat, sparks or
flame. Vapors may form an explosive mixture with air. Containers may
explode if exposed to fire.
Extinguishing Media:
For small fires, use dry chemical, carbon dioxide, water spray or
alcohol-resistant foam. Use water spray to cool fire-exposed
containers. Water may be ineffective. This material is lighter than
water and insoluble in water. The fire could easily be spread by the
use of water in an area where the water cannot be contained. Do NOT
use straight streams of water. For large fires, use dry chemical,
carbon dioxide, alcohol-resistant foam, or water spray. Cool
containers with flooding quantities of water until well after fire is
out.
**** 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. Clean up spills immediately,
observing precautions in the Protective Equipment section. Remove all
sources of ignition. Use a spark-proof tool. Provide ventilation. A
vapor suppressing foam may be used to reduce vapors. Water spray may
reduce vapor but may not prevent ignition in closed spaces.
**** SECTION 7 - HANDLING and STORAGE ****
Handling:
Wash thoroughly after handling. Remove contaminated clothing and
wash before reuse. Use with adequate ventilation. Ground and bond
containers when transferring material. Use spark-proof tools and
explosion proof equipment. Avoid contact with eyes, skin, and
clothing. Empty containers retain product residue, (liquid and/or
vapor), and can be dangerous. Keep away from heat, sparks and flame.
Avoid ingestion and inhalation. If peroxide formation is suspected,
do not open or move container. Do not pressurize, cut, weld, braze,
solder, drill, grind, or expose empty containers to heat, sparks or
open flames.
Storage:
Keep away from heat, sparks, and flame. Keep away from sources of
ignition. Do not store in direct sunlight. Store in a tightly closed
container. Keep from contact with oxidizing materials. Store in a
cool, dry, well-ventilated area away from incompatible substances.
Containers should be dated when opened and tested periodically for
the presence of peroxides. Should crystals form in a peroxidizable
liquid, peroxidation may have occurred and the product should be
considered extremely dangerous. In this instance, the container
should only be opened remotely by professionals. All peroxidizable
substances should be stored away from heat and light and be
protected from ignition sources.
**** SECTION 8 - EXPOSURE CONTROLS, PERSONAL PROTECTION ****
Engineering Controls:
Use explosion-proof ventilation equipment. Facilities storing or
utilizing this material should be equipped with an eyewash facility
and a safety shower. Use adequate general or local exhaust
ventilation to keep airborne concentrations below the permissible
exposure limits.
