Health Hazards Acute and Chronic:EYE CONTACT: IRRITATING AND MAY INJURE
EYE TISSUE IF NOT REMOVED PROMPTLY. SKIN CONTACT: FREQUENT OR
PROLONGED CONTACT MAY IRRITATE AND CAUSE DERMATITIS. INHALATION:
HIGH VAPOR CONCENTRATIONS ARE IRRI TATING TO THE RESPIRATORY TRACT.
INGESTION: ASPIRATED LIQUID MAY CAUSE BRONCHIOPNEUMONIA OR

Explanation of Carcinogenicity:THIS PRODUCT IS NOT LISTED BY IARC, NTP
OR OSHA AS A CARCINOGEN, MUTAGEN, TERATOGEN OR NEUROTOXIN.
Effects of Overexposure:EYE, SKIN & RESPIRATORY TRACT IRRITATION. MAY
CAUSE HEADACHES AND DIZZINESS, ARE ANESTHETIC AND MAY HAVE OTHER
CENTRAL NERVOUS SYSTEM EFFECTS.
Medical Cond Aggravated by Exposure:INDIVIDUALS WITH PREEXISTING
DISEASES OF THE CENTRAL NERVOUS SYSTEM, EYES, SKIN OR RESPIRATORY
SYSTEM MAY HAVE INCREASED SUSCEPTIBILITY TO THE TOXICITY OF
EXCESSIVE EXPOSURES.

First Aid:EYE: FLUSH IMMEDIATELY WITH PLENTY OF WATER FOR 15 MINUTES
WHILE LIFTING EYELIDS. GET MEDICAL ATTENTION. SKIN: REMOVE
CONTAMINATED CLOTHING. WASH SKIN WITH SOAP AND WATER. GET MEDICAL
ATTENTION. INHAL ATION: REMOVE TO FRESH AIR. IF NOT BREATHING, GIVE
ARTIFICIAL RESPIRATION. GET MEDICAL ATTENTION. INGESTION: DO NOT
INDUCE VOMITING. IF VOMITING OCCURS, KEEP HEAD BELOW HIPS. GET

Flash Point:=17.2C, 63.F
Autoignition Temp:=458.9C, 858.F
Lower Limits:1.2
Upper Limits:8.0
Extinguishing Media:FOAM OR DRY CHEMICAL.
Fire Fighting Procedures:USE WATER SPRAY TO COOL FIRE EXPOSED SURFACES
AND TO PROTECT PERSONNEL. STOP ANY LEAKS IF SAFE. IF MATERIAL HAS
NOT IGNITED, USE WATER SPRAY TO DISPERSE VAPORS.
Unusual Fire/Explosion Hazard:FLAMMABLE LIQUID, CAN RELEASE VAPORS THAT
FORM FLAMMABLE MIXTURE AT TEMPERATURE AT OR ABOVE THE FLASH POINT.
"EMPTY" CONTAINERS RETAIN DANGEROUS RESIDUE/VAPORS.

Spill Release Procedures:ELIMINATE SOURCES OF IGNITION. EVACUATE AREA.
PREVENT ADDITIONAL DISCHARGE OF MATERIAL IF SAFE TO DO SO. DIKE
WITH INERT MATERIAL TO RETAIN LIQUID. RECOVER BY PUMPING OR WITH A
SUITABLE ABSORBENT. DO NOT USE COMBUSTIBLE MATERIALS SUCH AS
SAWDUST.
Neutralizing Agent:NONE SPECIFIED BY MANUFACTURER.

Handling and Storage Precautions:STORE IN COOL, DRY, WELL VENTILATED
AREA. KEEP CONTAINERS CLOSED WHEN NOT IN USE. USE PROPER GROUNDING
PROCEDURES WHEN HANDLING MATERIAL.
Other Precautions:"EMPTY" CONTAINERS RETAIN PRODUCT RESIDUE AND CAN BE
DANGEROUS. DO NOT PRESSURIZE, CUT, WELD, BRAZE, SOLDER, DRILL,
GRIND OR EXPOSE SUCH CONTAINERS TO HEAT, FLAME, SPARKS, STATIC
ELECTRICITY OR OTHER SOURCES OF IGNITION; THEY MAY EXPLODE.

Respiratory Protection:WHERE CONCENTRATIONS IN AIR MAY EXCEED THE
PEL/TLV AND ENGINEERING, WORK PRACTICE OR OTHER MEANS OF EXPOSURE
REDUCTION ARE NOT ADEQUATE, NIOSH/MSHA APPROVED RESPIRATORS MAY BE
NECESSARY TO PREVENT OVE REXPOSURE BY INHALATION.
Ventilation:USE OF LOCAL EXHAUST VENTILATION IS RECOMMENDED TO CONTROL
PROCESS EMISSIONS NEAR THE SOURCE. USE LAB HOOD IF AVAILABLE.
Protective Gloves:CHEMICAL RESISTANT GLOVES
Eye Protection:CHEMICAL SPLASH GOGGLES
Other Protective Equipment:FOR OPEN SYSTEMS WHERE CONTACT IS LIKELY,
WEAR LONG SLEEVES. EYE WASH STATION & SAFETY SHOWER RECOMMENDED.
Work Hygienic Practices:WASH THOROUGHLY AFTER HANDLING AND BEFORE
EATING, DRINKING OR SMOKING. LAUNDER CONTAMINATED CLOTHING BEFORE
REUSE.
Supplemental Safety and Health
CHRONIC EFFECTS: THERE IS NO EVIDENCE THAT EXPOSURE TO MIBK ALONE
CAUSES PROGRESSIVE OR IRREVERSIBLE NEUROTOXIC EFFECTS. HOWEVER,
SIMULTANEOUS OVER-EXPOSURE TO MIBK AND N-HEXANE CAN POTENTIATE THE
KNO WN IRREVERSIBLE NEUROTOXIC EFFECTS OF N-HEXANE. EXPOSURE LEVELS
BELOW PEL/TLV HAVE NOT BEEN REPORTED TO CAUSE A PROBLEM.
