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. Avoid
breathing mist. Use explosion proof equipment. Keep container closed. Do not reuse container as it may
retain hazardous product residue.

Storage
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. To maintain stability and active oxygen content,
store below 30 C (86 F ).

8 EXPOSURE CONTROLS / PERSONAL PROTECTION

Engineering Controls
Investigate engineering techniques to reduce exposures. Provide ventilation if necessary to minimize
exposures. If practical, use local mechanical exhaust ventilation at sources of air contamination such as
open process equipment. Consult ACGIH ventilation manual or NFPA Standard 91 for design of exhaust
systems.

Eye / Face Protection
Use good industrial practice to avoid eye contact.

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.
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 搂 1910.134.


Airborne Exposure Guidelines for Ingredients

The components of this product have no established Airborne Exposure Guidelines
-Only those components with exposure limits are printed in this section.
-Skin contact limits designated with a "Y" above have skin contact effect. Air sampling alone is insufficient to accurately quantitate
exposure. Measures to prevent significant cutaneous absorption may be required.
-ACGIH Sensitizer designator with a value of "Y" above means that exposure to this material may cause allergic reactions.
-WEEL-AIHA Sensitizer designator with a value of "Y" above means that exposure to this material may cause allergic skin reactions.

This material is chemically unstable and should only be handled under specified conditions. See HANDLING AND STORAGE section
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.
Other Physical Data
Active Oxygen Content = 6.74 - 6.90% A[O]
