**** SECTION 3 - HAZARDS IDENTIFICATION ****
EMERGENCY OVERVIEW
Highly flammable. Irritating to eyes and skin.Light sensitive.Heat
sensitive.Moisture sensitive.
Potential Health Effects
Eye:
Causes eye irritation.
Skin:
Causes skin irritation.
Ingestion:
Causes gastrointestinal irritation with nausea, vomiting and
diarrhea.
Inhalation:
Causes respiratory tract irritation. May cause narcotic effects in
high concentration.
Chronic:
No information found.
**** SECTION 4 - FIRST AID MEASURES ****
Eyes:
Immediately flush eyes with plenty of water for at least 15 minutes,
occasionally lifting the upper and lower eyelids. Get medical aid
immediately.
Skin:
Immediately 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.
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. During a fire, irritating and highly toxic gases
may be generated by thermal decomposition or combustion.
Extinguishing Media:
Use foam, dry chemical, or carbon dioxide.
**** 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. Scoop up
with a nonsparking tool, then place into a suitable container for
disposal.
**** SECTION 7 - HANDLING and STORAGE ****
Handling:
Wash thoroughly after handling. Wash hands before eating. Remove
contaminated clothing and wash before reuse. Use only in a
well-ventilated area. 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. 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. Store in a cool, dry place. Do not store in direct
sunlight. Store in a tightly closed container. 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 process enclosure, local exhaust ventilation, or other
engineering controls to control airborne levels below recommended
exposure limits.
Exposure Limits
CAS# 105-57-7:
Personal Protective Equipment
Eyes:
Wear appropriate protective eyeglasses or chemical
safety goggles as described by OSHA's eye and face
protection regulations in 29 CFR 1910.133 or European
Standard EN166.
Skin:
Wear appropriate protective gloves to prevent skin
exposure.
Clothing:
Wear appropriate protective clothing to prevent skin
exposure.
Respirators:
Follow the OSHA respirator regulations found in 29
CFR 1910.134 or European Standard EN 149. Use a
NIOSH/MSHA or European Standard EN 149 approved
respirator if exposure limits are exceeded or if
irritation or other symptoms are experienced.

**** SECTION 10 - STABILITY AND REACTIVITY ****
Chemical Stability:
Under normal storage conditions, peroxidizable compounds can form
and accumulate peroxides which may explode when subjected to heat or
shock. This material is most hazardous when peroxide levels are
concentrated by distillation or evaporation.
Conditions to Avoid:
High temperatures, mechanical shock, light, ignition sources,
moisture.
Incompatibilities with Other Materials:
Strong oxidizing agents, acids.
Hazardous Decomposition Products:
Carbon monoxide, irritating and toxic fumes and gases, carbon
dioxide.
Hazardous Polymerization: Has not been reported
