PHYSICAL HAZARDS
Severe Irritant.
HEALTH HAZARDS
The ACGIH Ceiling STEL is 1.5 mg/m 3 (0.2 ppm) for Methyl Ethyl Ketone Peroxide.
EXPOSURE LIMITS
ROUTES OF EXPOSURE
Severe skin irritant, causes redness, blistering, and edema.
Skin Contact
Eye contact causes severe corrosion and may cause blindness.
Eye Contact
Human systemic effects by ingestion: changes in structure or function of esophagus,
Ingestion
nausea, or vomiting, and other gastrointestinal effects.
Moderately toxic by inhalation.
Inhalation
Prolonged inhalation of vapors may cause mucous membrane irritation and vertigo.
EFFECTS OF OVER-EXPOSURE
There are no known medical conditions, which are recognized as being aggravated
by exposure.
SECTION 4 - FIRST-AID MEASURES
Immediately remove any contaminated clothing. Wash contaminated area
Skin
thoroughly with soap and copious amounts of water for at least 15 minutes. If
irritation or adverse symptoms develop, seek medical attention.
Remove any contact lenses at once. Flush eyes with water for at least 15 minutes.
Eyes
Ensure adequate flushing by separating the eyelids with fingers. If irritation or
adverse symptoms develop, seek medical attention.
Ingestion Do Not induce vomiting. Drink plenty of water. Immediately call a physician. For
aid to physician, suggest local Poison Control Center.
Remove to fresh air, if coughing, breathing becomes labored, irritation develops or
Inhalation
other symptoms develop, seek medical attention at once, even if symptoms develop
several hours after the exposure.
SECTION 5 - FIRE-FIGHTING MEASURES
>200掳F (93掳C), C.O.C.
FLASH POINT
Not established.
FLAMMABLE LIMITS
Not established.
AUTOIGNITION POINT
Water from a safe distance - preferably with a fog nozzle. In case of very small fires,
EXTINGUISHING MEDIA
other means such as carbon dioxide, foam or dry chemical extinguishers may be
effective. Dry chemical combined with MEKP formulations may re-ignite. Light
water additives may be particularly effective at extinguishing MEKP fires.
Firemen should be equipped with protective clothing and SCBA鈥? In case of fire
s.
SPECIAL FIRE FIGHTING
near storage area, cool the containers with water spray. If dry chemical is used to
PROCEDURES
extinguish an MEKP fire, the extinguished area must be thoroughly wetted down with
water to prevent re-ignition.

material with water and absorb with an inert absorbent material such as perlite,
OF SPILL OR RELEASE
vermiculite, or sand. Sweep up using non-sparking tools and place in a clean
polyethylene drum or a polyethylene pail. DO NOT place into a steel container,
lined or unlined, as a decomposition may occur. Treat any contaminated
cardboard packaging as hazardous waste. Wet container contents with additional
water prior to sealing.
SECTION 7 - HANDLING AND STORAGE
Rotate stock using the oldest material first. Avoid contact with skin, eyes and
HANDLING
clothing. Use PPE as specified in Section 8. Keep containers closed to prevent
contamination. Keep away from sources of heat, sparks or flame. Do not add to hot
solvents or monomers as a violent decomposition and/or reaction may result. When
using spray equipment, never spray raw MEKP onto curing or into raw resin or flues.
Keep MEKP in its original container. DO NOT USE NEAR FOOD OR DRINK. Wash
thoroughly after handling.
The stability of MEKP formulations is directly related to the shipping and storage
STORAGE
temperature history. Cool storage at 80掳F (27掳C) or below is recommended for
longer shelf life and stability. Prolonged storage at elevated temperatures of 100掳F
(38掳C) and higher will cause product degradation, gassing and potential container
rupture which can result in a fire and/or explosion. Store out of direct sunlight in a
well ventilated area away from combustible and incompatible materials. DO NOT
STORE WITH FOOD OR DRINK. Refer to NFPA 432 Code for the Storage of
Organic Peroxide Formulations from the National Fire Protection Association for
additional storage information.
Unmixed, uncontaminated material, remaining at the end of the day, shall be

returned to a proper organic peroxide storage area. Under no circumstances should
material be returned to the original container.
SECTION 8 - EXPOSURE CONTROL/PERSONAL PROTECTION
Mechanical, general.
VENTILATION
If airborne concentrations are expected to exceed acceptable levels wear a NIOSH
RESPIRATORY PROTECTION
approved air-purifying respirator with an organic vapor cartridge or canister. When
using respirators refer to OSHA鈥?29CFR 1910.134.
s
Safety goggles recommended. Permanent eyewash is highly recommended.
EYE PROTECTION
Protective gloves recommended, solvent resistant, such as butyl rubber, nitrile or
