Potential Health Effects
Inhalation and skin contact are expected to be the primary routes of occupational exposure to this material. Based on
its composition, it is anticipated to be practically non-toxic if swallowed, inhaled or absorbed through skin, practically
non-irritating to eyes and slightly irritating to skin. High vapor concentrations may be irritating to the eyes, skin and

respiratory tract.
4 FIRST AID MEASURES
IN CASE OF CONTACT, flush the area with plenty of water. Remove material from clothing. Wash clothing
before reuse.
IF SWALLOWED, induce vomiting as directed by medical personnel. Get medical attention. NEVER GIVE
ANYTHING BY MOUTH TO AN UNCONSCIOUS PERSON.
IF INHALED, remove to fresh air. If breathing is difficult, get medical attention.

Flash Point 46 C (114 F) Flash Point Method Seta CC
Flammable Limits- Upper NE
NE
Lower
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. Do not cut, grind or weld on or near containers - explosion hazard. Avoid breathing vapor or
mist.
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 32 C (90 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
Minimize skin contamination by following good industrial hygiene practice. Wearing rubber gloves is
recommended. Wash hands and contaminated 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 = 9.73% Min.

11 TOXICOLOGICAL INFORMATION
Toxicological Information
Data on this material and/or its components are summarized below.
1,1-Bis(t-butylperoxy)-3,3,5-trimethylcyclohexane
Single exposure (acute) studies indicate that this material is practically non-toxic if swallowed (rat LD50 >12,918
mg/kg, 75% in dibutyl phthalate), absorbed through skin (rabbit LD50 >8,000 mg/kg, 75% in dibutyl phthalate) or
inhaled (rat 4-hr LC50 >400 mg/l, 75% in dibutyl phthalate), practically non-irritating to rabbit eyes (1.3/110, 75%
in dibutyl phthalate) and slightly irritating to rabbit skin (2.15/8.0, 97.4% purity). No skin allergy was observed in
guinea pigs following repeated exposure (97.4% purity). Effects following repeated oral exposure of mice in
their feed included increased mortality, decreased body weight, bone marrow effects and associated anemia
and splenic atrophy, and liver effects (swelling of the hepatocytes). In a subsequent long-term study in mice,
similar liver effects were noted. No significant increase in tumors was observed in this study. No genetic
changes were observed in standard tests using bacteria.
tert-Butyl hydroperoxide
Skin allergy was observed in guinea pigs following repeated exposure. Short-term exposure of rats to aerosol
produced increased ocular and nasal secretions and decreased body weights. Short-term oral administration
produced severe irritation and submucosal edema of the stomach in rats. Male rats repeatedly dosed orally
developed renal lesions. Inhalation by female rats during pregnancy produced nonspecific impairment in the
development of their fetuses in addition to maternal toxicity. No birth defects were observed in the offspring of
rats exposed orally during pregnancy, although some maternal effects were seen. Genetic changes were
observed in tests using bacteria or animal cells, but not in tests using animals.

13 DISPOSAL CONSIDERATIONS
Waste Disposal
Dispose of in accordance with federal, state and local regulations. Dilution followed by incineration is the
preferred method. Dilution ration of 10:1 in a clean, compatible, combustible solvent (i.e., Fuel Oil #2, mineral
oil) will reduce reactivity hazard during incineration and transportation.
