Section 3 - Hazards Identification

EMERGENCY OVERVIEW
Appearance: clear, colorless to pale yellow liquid. Flash Point: > 60 deg C.
Danger! Organic peroxide. Heat or contamination
may cause hazardous decomposition. Peroxides and decomposition
products are flammable and can ignite with explosive force if
confined. Causes eye, skin, and respiratory tract irritation.
Combustible liquid and vapor.
Target Organs: Respiratory system, eyes, skin.
Potential Health Effects
Eye:
Causes eye irritation.
Skin:
Causes skin irritation. Prolonged exposure may produce blisters. Not
expected to cause an allergic skin reaction.
Ingestion:
May cause irritation of the digestive tract. May cause nausea and
vomiting. May be harmful if swallowed.
Inhalation:
Causes respiratory tract irritation.
Chronic:
No information found.
Section 4 - First Aid Measures
|
Eyes:
In case of contact, immediately flush eyes with plenty of water for a
t 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:
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:
Treat symptomatically and supportively.
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. Strong oxidizer. Contact with other material may
cause fire. 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. Containers may explode in the heat
of a fire. Combustible liquid. Runoff to sewer may create fire or
explosion hazard. Evacuate unnecessary personnel. Peroxides and
decomposition products are flammable and can ignite with explosive
force if confined. This product can produce flammable vapors which
may travel to a source of ignition and flash back.
Extinguishing Media:
Use water fog or spray, dry chemical, foam or carbon dioxide.
Flash Point: > 60 deg C (> 140.00 deg F)
Autoignition Temperature: Not available.
Explosion Limits, Lower:Not available.
Upper: Not available.
NFPA Rating:
(estimated) Health: 2; Flammability: 3; Instability: 3; Special Hazard: OX
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. Evacuate
unnecessary personnel. Approach spill from upwind. If permitted to
enter sewers, this material may create a fire or explosion hazard.
Section 7 - Handling and Storage
|
Handling:
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 container tightly closed. Avoid contact with clothing
and other combustible materials. Avoid ingestion and inhalation. Wash
clothing before reuse. Do not pressurize, cut, weld, braze, solder,
drill, grind, or expose empty containers to heat, sparks or open
flames. Keep away from heat and flame. Do not use air pressure to
empty containers.
Storage:
Keep away from heat, sparks, and flame. Store in a tightly closed
container. Store in a cool, dry, well-ventilated area away from
incompatible substances. Keep away from reducing agents. Store in
explosion-proof refrigerator. Keep away from acidic, alkaline,
combustible and oxidizing materials. To insure product quality,
storage temperature should not exceed 25°C. To insure against
possible exothermic self-accelerating decomposition, storage
temperature must not exceed 55°C (derived from the SADT of 60°C).
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
ventilation to keep airborne concentrations low.

Section 10 - Stability and Reactivity
|
Chemical Stability:
Stable at room temperature in closed containers under normal storage
and handling conditions. A dangerous self-accelerating decomposition
reaction and, under certain circumstances, explosion or fire can be
caused by direct contact with incompatible substances or by thermal
decomposition at and above the SADT (see Section 16).
Conditions to Avoid:
Ignition sources, excess heat, confined spaces.
Incompatibilities with Other Materials:
Strong oxidizing agents, strong reducing agents, strong acids, strong
bases, heavy metals.
