Potential Health Effects

Inhalation and skin contact are expected to be the primary routes of occupational exposure to this material. On the
basis of available information, exposure to this material is not expected to produce significant adverse human health
effects; however, use of appropriate good industrial hygiene and safety precautions to control exposure is
recommended when handling or using this material.

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.

5 FIRE FIGHTING MEASURES

Fire and Explosive Properties
Auto-Ignition Temperature NE
Flash Point 92 C (198 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

7 HANDLING AND STORAGE

explosion proof equipment. Keep container closed. Do not reuse container as it may retain hazardous
product residue. Minimize exposure to ambient temperatures.

Storage
REFRIGERATION REQUIRED. Detached storage is preferred. Keep out of direct sunlight. 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. Minimize exposure to ambient temperatures.
To maintain stability and active oxygen content, store below 10 C (50 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.

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
Where airborne exposure is likely, use NIOSH approved respiratory protection equipment appropriate to the
material and/or its components. If exposures cannot be kept at a minimum with engineering controls, consult
respirator manufacturer to determine appropriate type equipment for a 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.

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.

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 = 7.18%
Refractive index = 1.4306 @ 20C
Density = 7.48 lbs/gal @ 20 C

10 STABILITY AND REACTIVITY

Incompatibility
Contact with foreign materials, such as, strong acids, alkalis, oxidizers, reducing agents, amines, and
promoters/accelerators may result in a violent decomposition reaction or in product degradation.
Hazardous Decomposition Products
Temperatures at or above the SADT can result in the release of hazardous decomposition products which are
flammable and autoignite.

Mild skin allergy was observed in guinea pigs following repeated exposure. No genetic changes were observed
in tests using animals; however, genetic changes did occur using bacteria.

12 ECOLOGICAL INFORMATION

Ecotoxicological Information
This material is moderately toxic to guppies (96-hr LC50 8.7 mg/l) and Daphnia magna (48-hr EC50 7.5 mg/l).
It is highly toxic to algae (72-hr EC50 0.31 mg/l).

Chemical Fate Information
This material is readily biodegradable (55% biodegradation in 28 days). An EC50 of 64 mg/l activated sludge
was reported in an activated sludge respiration inhibition test.

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.
