    PROLONGED AND REPEATED OVEREXPOSURE MAY CAUSE DAMAGE TO LIVER,
    DAMAGE TO THE KIDNEYS.
Explanation of Carcinogenicity:IRAC: ANIMAL INDEFINITE
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

    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 Measures  =======================

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:
    REMOVE TO  FRESH AIR. GIVE MOUTH-TO-MOUTH RESUSCITATION IF NOT
    BREATHING. GIVE OXYGEN IF BREATHING IS DIFFICULT. GET MEDICAL
    ATTENTION. INGESTION: DO NOT INDUCE VOMITING. GET MEDICAL ATTENTION
    IMMEDIATELY.

=====================  Fire Fighting Measures  =====================

Flash Point:NONE
Autoignition Temp:Autoignition Temp Text:NONE
Lower Limits:13
Upper Limits:23
Extinguishing Media:NONCOMBUSTIBLE. USE WATER SPRAY, CARBON DIOXIDE OR
    DRY CHEMICAL AS APPROPRIATE FOR SURROUNDING FIRE CONDITIONS.
Fire Fighting Procedures:WEAR FIRE FIGHTING PROTECTIVE EQUIPMENT AND A
    FULL FACED SELF CONTAINED BREATHING APPARATUS. COOL FIRE EXPOSED
    CONTAINERS WITH WATER SPRAY.
Unusual Fire/Explosion Hazard:COMBUSTION OR HEAT OF FIRE MAY PRODUCE
    TOXIC FUMES OF HYDROGEN CHLORIDE GAS AND PHOSGENE GAS. FORMS
    FLAMMABLE VAPOR-AIR MIXTURES ABOVE AMBIENT TEMPERATURES.

==================  Accidental Release Measures  ==================

Spill Release Procedures:SMALL SPILL: MOP UP OR WIPE UP WITH RAGS OR
    TOWELS. TAKE OUTDOORS. LARGE SPILLS: EVACUATE AREA. WEAR SCBA.
    VENTILATE AREA. DIKE TO CONTAIN LIQUID. TRANSFER LIQUID TO CLOSED
    METAL CONTAINER. RESIDUE WI LL EVAPORATE QUICKLY. KEEP OUT OF
    WATERSUPPLY.
Neutralizing Agent:NONE-RECLAIM IF POSSIBLE.

======================	Handling and Storage  ======================

Handling and Storage Precautions:VAPORS ARE HEAVIER THAN AIR & WILL
    COLLECT IN LOW AREAS OF DEGREASERS, STORAGE TANKS, ETC. DO NOT
    ENTER THESE AREAS WITHOUT SCBA & OBSERVER TO ASSIST.
Other Precautions:THIS MATERIAL OR ITS VAPORS WHEN IN CONTACT WITH
    FLAMES, HOT GLOWING SURFACES OR ELECTRIC ARCS CAN DECOMPOSE TO FORM
    HYDROGEN CHLORIDE GAS AND TRACES OF PHOSGENE.

=============  Exposure Controls/Personal Protection  =============

Respiratory Protection:FOR A SINGLE SHORT-TERM EXPOSURE, USE NIOSH/MSHA
    APPROVED RESPIRATOR WITH ORGANIC VAPOR CARTRIDGE. USE A POSITIVE
    PRESSURE SELF-CONTAINED BREATHING APPARATUS IF IN CONFINED OR
    POORLY VENTILATED AREAS.
Ventilation:LOCAL EXHAUST RECOMMENDED TO CONTROL VAPORS BELOW 50% OF
    TLV.
Protective Gloves:NEOPRENE, PVA GLOVES RECOMMENDED.
Eye Protection:CHEMICAL SAFETY GOGGLES & FACE SHIELD.
Other Protective Equipment:APRON, BOOTS AND WORK CLOTHING TO MINIMIZE
    EXPOSURE. EYE WASH STATION & SAFETY SHOWER RECOMMENDED.
