Health Hazards Acute and Chronic:ACUTE-MAY CAUSE EYE & SKIN
IRRITATION.MAY CAUSE SKIN CHEMICAL BURNS.INHALATION:MAY CAUSE
RESPIRATORY TRACT IRRITATION,CNS DEPRESSION,LOSS OF CONSCIOUSNESS &
EVEN DEATH.INGESTION: SLIGHTLY TOXIC.HIGH D OSE->CNS
DEPRESSION.CHRONIC-PROLONGED/REPEATED CONTACT WITH LIQUID ON THE
SKIN CAN CAUSE IRRITATION AND DERMATITIS.
Explanation of Carcinogenicity:LISTED AS A SUSPECTED CARCINOGEN BY IARC
(2B) AND NTP (AC).
Effects of Overexposure:SEE HEALTH HAZARDS SECTION. AT VERY HIGH
CONCENTRATIONS, METHYLENE CHLORIDE INHALATION CAN INDUCE CARDIAC
SENSITIZATION TO EPINEPHRINE-LIKE COMPOUNDS IN EXPERIMENTAL
ANIMALS. MAY INDUCE CARBOXYHEMOGLO BINEMIA. THIS MATERIAL IS
PRACTICALLY NONTOXIC IN TERMS OF ACUTE EXPOSURE. LC50 IN MICE IS
ABOUT 50 G/M3(15,000 PPM).
Medical Cond Aggravated by Exposure:NOT GIVEN.

First Aid:INHALATION:REMOVE TO FRESH AIR.IF NOT BREATHING,GIVE CPR.IF
BREATHING IS DIFFICULT,GIVE OXYGEN.CALL A PHYSICIAN. EYE:FLUSH
IMMEDIATELY WITH WATER FOR 15 MINUTES.GET MEDICAL ATTENTION.SKIN:
WASH WITH S OAP & WATER.INGESTION:IF CONSCIOUS,DRINK 1-2 GLASSES OF
WATER & INDUCE VOMITING.GET IMMEDIATE MEDICAL ATTENTION.

Flash Point:DOES NOT FLASH
Extinguishing Media:MEDIA APPROPRIATE FOR SURROUNDING FIRE.
Fire Fighting Procedures:WEAR FIRE FIGHTING PROTECTIVE EQUIPMENT AND A
FULL FACED SELF CONTAINED BREATHING APPARATUS. EVACUATE AREA. COOL
FIRE EXPOSED CONTAINERS WITH WATER SPRAY.
Unusual Fire/Explosion Hazard:METHYLENE CHLORIDE VAPORS IN
CONCENTRATIONS OF ABOUT 12-19% BY VOLUME CAN BE IGNITED BY VERY
HIGH ENERGY SOURCES (ABOVE 65 JOULES).

Spill Release Procedures:VENTILATE AREA.WEAR SKIN & EYE PROTECTION & A
POSITIVE PRESSURE AIR-SUPPLIED RESPIRATOR DURING CLEAN-UP.CONTAIN
THE SPILL.PREVENT LIQUID FROM ENTERING SEWERS.SOAK UP LIQUID WITH
ABSORBENT & SHOVEL INT O WASTE CONTAINER.REMOVE CONTAINER FROMWORK
AREA.
Neutralizing Agent:NONE

Handling and Storage Precautions:STORAGE-STORE IN WELL-VENTILATED AREA
AWAY FROM HEAT & SUNLIGHT.
Other Precautions:METHYLENE CHLORIDE VAPORS ARE HEAVIER THAN AIR AND
WILL COLLECT IN LOW AREAS. THIS MATERIAL OR ITS VAPORS WHEN IN
CONTACT WITH FLAMES, HOT GLOWING SURFACES OR ELECTRIC ARCS CAN
DECOMPOSE TO FORM HYDRO GEN CHLORIDE GAS AND TRACES OF PHOSGENE.

Respiratory Protection:IN HIGH VAPOR AREA, USE NIOSH/MSHA APPROVED
RESPIRATOR WITH ORGANIC VAPOR CARTRIDGE. FOR HIGH CONCENTRATIONS
AND OXYGEN-DEFICIENT ATMOSPHERES, USE POSITIVE PRESSURE
AIR-SUPPLIED RESPIRATOR.
Ventilation:LOCAL EXHAUST RECOMMENDED. VENTILATE LOW-LYING AREAS WHERE
DENSE VAPORS MAY COLLECT.
Protective Gloves:PVA
Eye Protection:CHEMICAL TIGHT GOGGLES & FULL FACESHIELD
Other Protective Equipment:APRON AND WORK CLOTHING TO MINIMIZE
EXPOSURE. EYE WASH STATION & SAFETY SHOWER RECOMMENDED.
Work Hygienic Practices:WASH THOROUGHLY AFTER USE AND BEFORE EATING,
SMOKING OR USING TOILET FACILITIES. DO NOT BREATH VAPORS OR MIST.
Supplemental Safety and Health
MSDS COPIED FROM ANOTHER DICHLOROMETHANE OF GOOD QUALITY, SAME NSN.
NOTE TO PHYSICIAN: METHYLENE CHLORIDE IS METABOLIZED TO CARBON
MONOXIDE; WHICH THEN REACTS WITH HEMOGLOBIN & REDUCES THE
OXYGEN-CAR RYING CAPACITY OF THE BLOOD. DO NOT ADMINISTER
ADRENALIN.
