AND EVEN DEATH CAN OCCUR AT HIGH LEVELS OF EXPOSURE. CHRONIC:
PROLONGED OR REPEATED CONTACT WITH LIQUID ON THE SKIN CAN CAUSE
IRRITATION AND DERMATITIS.
Explanation of Carcinogenicity:LISTED AS A POTENTIAL CARCINOGEN BY
IARC. NOT BELIEVED TO POSE A MEASURABLE RISK TO MAN WHEN HANDLED AS
RECOMMENDED.
Effects of Overexposure:HEADACHE, DIZZINESS, DROWSINESS, NAUSEA,
TINGLING OR NUMBNESS OF THE EXTREMITIES, SENSES OF FULLNESS IN THE
HEAD, SENSE OF WARMTH, STUPOR OR DULLNESS, LETHARGY AND
DRUNKENNESS. INHALATION OF HIGH CONC ENTRATIONS MAY LEAD TO
UNCONSCIOUSNESS,REDUCED ABILITY OF THE BLOOD TO TRANSPORT OXYGEN,
CARDIAC ARRHYTHMIAS AND DEATH.
Medical Cond Aggravated by Exposure:METHYLENE CHLORIDE IS METABOLIZED
TO CARBON MONOXIDE. THIS MAY BE SUFFICIENT TO PRODUCE A SUBSTANTIAL
STRESS ON THE CARDIOVASCULAR SYSTEM. PERSONS WITH LIVER OR KIDNEY
DISORDERS ARE AT INCREASED RISK.

First Aid:EYES: FLUSH WITH RUNNING WATER FOR 15 MINUTES WHILE HOLDING
EYELID. GET MEDICAL ATTENTION IMMEDIATELY. SKIN: WASH WITH WATER.
REMOVE CONTAMINATED CLOTHING. GET MEDICAL ATTENTION. INHALATION:

HAZARDOUS DECOMPOSITION PRODUCTS AND VAPORS.

Spill Release Procedures:SMALL SPILL: MOP UP OR WIPE UP WITH RAGS OR
TOWELS. TAKE OUTDOORS. LARGE SPILLS: EVACUATE AREA. WEAR SCBA.
