Material Safety Data Sheet
Arkema Inc.
Inhalation and skin contact are expected to be the primary routes of occupational exposure to this material. Based on
single exposure animal tests, it is considered to be slightly toxic if swallowed or absorbed through skin, practically non-
toxic if inhaled, moderately irritating to eyes and practically non-irritating to skin. Prolonged or repeated contact
removes oils from the skin and may dry skin and cause irritation, redness and rash. Repeated exposure may cause an
allergic skin reaction. High vapor concentrations may be irritating to the eyes and respiratory tract, and may result in
central nervous system (CNS) effects such as headache, dizziness, nausea, drowsiness and, in severe exposures,
loss of consciousness and death. Mild to severe lung injury may occur if this material is drawn into the lungs
(aspirated) during swallowing, or during vomiting after swallowing. Symptoms of injury may include increased breathing
and heart rate, coughing and related signs of respiratory distress.
4 FIRST AID MEASURES
IF IN EYES, immediately flush with plenty of water. Get medical attention if irritation persists.
IF ON SKIN, immediately wash with soap and plenty of water. Remove contaminated clothing and shoes.
Get medical attention. Wash clothing before reuse. Destroy contaminated shoes.
IF SWALLOWED, do NOT induce vomiting. Give water to drink. Get medical attention immediately. NEVER
GIVE ANYTHING BY MOUTH TO AN UNCONSCIOUS PERSON.
IF INHALED, remove to fresh air. If breathing is difficult, get medical attention.

Extinguishing Media
Use water spray, foam or dry chemical.
Fire Fighting Instructions
Fight fire with large amounts of water from a safe distance. Use water spray to cool containers exposed to fire.
Fire fighters and others who may be exposed to products of combustion should wear full fire fighting turn out
gear (full Bunker Gear) and self-contained breathing apparatus (pressure demand NIOSH approved or
equivalent). Fire fighting equipment should be thoroughly decontaminated after use. After a fire, wait until the
material has cooled to room temperature before initiating clean up activities.
Fire and Explosion Hazards
Contact with incompatible materials or exposure to temperatures exceeding the SADT may result in a self
accelerating decomposition reaction with release of flammable vapors which may autoignite.
6 ACCIDENTAL RELEASE MEASURES
In Case of Spill or Leak
Use inert, non-combustible absorbant material such as sodium bicarbonate, sodium carbonate, calcium
carbonate, clean sand or non-acidic clay directly on the spilled peroxide, then wet down (dampen) the mixture

with water. Sweep or scoop up using non-sparking tools and place into a polyethylene bag for disposal. The
sweepings should be wetted down further with water. Dispose of immediately. After all of the material has
been collected, wash down the area with detergent and water. Consult a regulatory specialist to determine
appropriate state or local reporting requirements, for assistance in waste characterization and/or hazardous
waste disposal and other requirements listed in pertinent environmental permits.
7 HANDLING AND STORAGE
Handling
Contact with incompatible materials or exposure to temperatures exceeding SADT (See Section (9) may
result in a self accelerating decomposition reaction with release of flammable vapors which may autoignite.
Keep away from heat sparks and flame. Avoid contamination. Use only with adequate ventilation. Use
explosion proof equipment. Keep container closed. Do not reuse container as it may retain hazardous
product residue. Avoid contact with eyes. Wash thoroughly after handling. Avoid breathing vapor or mist.
Wash thoroughly after handling. Avoid prolonged or repeated contact with skin.
Storage
Store below 38 C/100 F to maintain stability and active oxygen content. Detached storage is preferred.
Store out of direct sunlight in a cool well-ventilated place. Store away from combustibles and incompatible
materials. Refer also to National Fire Protection Agency (NFPA) Code 432, Code for the Storage of Organic
Peroxide Formulations.
8 EXPOSURE CONTROLS / PERSONAL PROTECTION
Engineering Controls
Investigate engineering techniques to reduce exposures below airborne exposure limits. Provide ventilation
if necessary to control exposure levels below airborne exposure limits (see below). If practical, use local
mechanical exhaust ventilation at sources of air contamination such as open process equipment.
Eye / Face Protection
Where there is potential for eye contact, wear chemical goggles and have eye flushing equipment available.
Skin Protection
Wear appropriate chemical resistant protective clothing and chemical resistant gloves to prevent skin
contact. Consult glove manufacturer to determine appropriate type glove material for given application.
Wear face shield and chemical resistant clothing such as a rubber apron when splashing may occur. Rinse
contaminated skin promptly. Wash contaminated clothing and clean protective equipment before reuse.
Wash skin thoroughly after handling.
Respiratory Protection
Avoid breathing vapor or mist. Where airborne exposure is likely, use NIOSH approved respiratory
protection equipment appropriate to the material and/or its components. Full facepiece equipment is
recommended and, if used, replaces need for face shield and/or chemical goggles. If exposures cannot be
kept at a minimum with engineering controls, consult respirator manufacturer to determine appropriate type
equipment for given application. Observe respirator use limitations specified by NIOSH or the manufacturer.
For emergency and other conditions where there may be a potential for significant exposure, use an
approved full face positive-pressure, self-contained breathing apparatus or positive-pressure airline with
auxiliary self-contained air supply. Respiratory protection programs must comply with 29 CFR ?1910.134.

of this MSDS for specified conditions.
SADT - Self Accelerating Decomposition Temperature. Lowest temperature at which the tested package size will undergo a self-
accelerating decomposition reaction. This reaction will generate flammable vapors which may autoignite. The length of time to
generated a decomposition reaction, after the SADT has been reached or exceeded, is dependent upon how much the SADT has
been exceeded and the length of time needed for the reaction exotherm (heat spike from increasing decomposition rate) to initiate a
rapid decomposition reaction. Typically, SADT is inversely proportional to package size. Larger packages will have a lower SADT
due to smaller ratio to heat transfer area to volume of product.

11 TOXICOLOGICAL INFORMATION
Toxicological Information
Data on this material and/or its components are summarized below.
t-Butyl Peroxyacetate
Single exposure (acute) studies indicate that this material is slightly toxic if swallowed (rat LD50 2,562 mg/kg) or
absorbed through skin (rabbit LD50 4,757 mg/kg), practically non-toxic if inhaled (rat 4-hr LC50 6.1 mg/l),
moderately irritating to rabbit eyes and practically non-irritating to rabbit skin (24-hr exposure, 0.8/8.0).
Skin allergy was observed in guinea pigs following repeated exposure. No genetic changes were observed in
tests using animal cells.
Petroleum distillate/Odorless mineral spirits
No skin allergy was observed in guinea pigs or humans following repeated exposure, although skin irritation was
noted. Human volunteers exposed to 100 ppm for 6 hours noted no symptoms associated with exposure.
Repeated inhalation studies in rats produced kidney tubule damage in male rats only indicative of hydrocarbon
nephropathy, but extensive studies have demonstrated that these effects occur only in male rats and are not
relevant to humans. Repeated inhalation exposure in dogs produced no adverse effects. Repeated skin
application of these types of materials has produced skin tumors in mice. No birth defects were observed in the
offspring of rats following inhalation exposure during pregnancy. No genetic changes were observed in tests
using bacteria, animal cells or animals.
