**** SECTION 3 - HAZARDS IDENTIFICATION ****
EMERGENCY OVERVIEW
Highly flammable. May form explosive peroxides. Irritating to eyes
and respiratory system. Limited evidence of a carcinogenic effect.
Repeated exposure may cause skin dryness or cracking.Hygroscopic
(absorbs moisture from the air).
Potential Health Effects
Eye:
Causes eye irritation.
Skin:
May cause skin irritation. May be absorbed through the skin in
harmful amounts. Prolonged and/or repeated contact may cause
irritation and/or dermatitis.
Ingestion:
May cause gastrointestinal irritation with nausea, vomiting and
diarrhea. 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.
Inhalation:
Effects may be delayed. Inhalation of high concentrations may cause
central nervous system effects characterized by nausea, headache,
dizziness, unconsciousness and coma. Causes respiratory tract
irritation. Inhalation of vapor may cause severe respiratory tract
irritation. Olfactory fatigue may occur.
Chronic:
May cause liver and kidney damage. May cause cancer according to
animal studies.
**** SECTION 4 - FIRST AID MEASURES ****
Eyes:
In case of contact, immediately flush eyes with plenty of water for
at least 15 minutes. Get medical aid.
Skin:
In case of contact, flush skin with plenty of water. Remove
contaminated clothing and shoes. Get medical aid if irritation
develops and persists. Wash clothing before reuse.
Ingestion:
Possible aspiration hazard. If swallowed, do not induce vomiting
unless directed to do so by medical personnel. Never give anything by
mouth to an unconscious person. Get medical aid.
Inhalation:
If inhaled, remove to fresh air. 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. During a fire, irritating and highly toxic gases
may be generated by thermal decomposition or combustion. Use water
spray to keep fire-exposed containers cool. Flammable liquid and
vapor. May form explosive peroxides. May accumulate static
electrical charges, and may cause ignition of its own vapors.
Approach fire from upwind to avoid hazardous vapors and toxic
decomposition products. Vapors are heavier than air and may travel to
a source of ignition and flash back. Vapors can spread along the
ground and collect in low or confined areas.
Extinguishing Media:
Use water spray, dry chemical, carbon dioxide, or alcohol-resistant
foam.
**** 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. Avoid runoff into storm sewers and
ditches which lead to waterways. Clean up spills immediately,
observing precautions in the Protective Equipment section. Remove all
sources of ignition. Use a spark-proof tool. Flush spill area with
water. Provide ventilation. A vapor suppressing foam may be used to
reduce vapors.
**** SECTION 7 - HANDLING and STORAGE ****
Handling:
Wash thoroughly after handling. Remove contaminated clothing and
wash before reuse. Use spark-proof tools and explosion proof
equipment. Loosen closure cautiously before opening. Avoid contact
with eyes, skin, and clothing. Empty containers retain product
residue, (liquid and/or vapor), and can be dangerous. Take
precautionary measures against static discharges. 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. Use only with adequate
ventilation. Avoid breathing vapor or mist.
Storage:
Store in a tightly closed container. Store in a cool, dry,
well-ventilated area away from incompatible substances.
Flammables-area. After opening, purge container with nitrogen before
reclosing. Periodically test for peroxide formation on long-term
storage. Addition of water or appropriate reducing materials will
lessen peroxide formation. 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:
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.
