*  Exposure Controls/Personal Protection  *
Respiratory Protection:POSITIVE PRESSURE AIR LINE WITH MASK OR SELF-
    CONTAINED BREATHING APPARATUS SHOULD BE USED FOR EMERGENCY USE.
Ventilation:USE HOOD WITH FORCED VENTILATION &/OR LOCAL EXHAUST TO
    PREVENT ACCUMULATION ABOVE THE TLV.
Other Protective Equipment:SAFETY SHOES, SAFETY SHOWER & EYEWASH
    FOUNTAIN
Work Hygienic Practices:NO SMOKING
Supplemental Safety and Health
HCC IS BASED ON THE FACT THAT THIS CONTAINS 2.5% METHANE AND IS NOT
    PURE METHANE-PROBABLY IS NOT FLAMMABLE AT THIS CONCENTRATION (LEL
    IS 5%). MSDS IS FOR ONE INGREDIENT FOUND IN THIS NSN.
*  Product Identification  *
Product ID:METHANE, METHYL HYDRIDE, MARSH GAS
*  Composition/Information on Ingredients  *
Ingred Name:METHANE
Fraction by Wt: 2.5%
Other REC Limits:NONE DETERMINED
*  Hazards Identification  *
Routes of Entry: Inhalation:YES  Skin:NO  Ingestion:NO
Reports of Carcinogenicity:NTP:NO    IARC:NOOSHA:NO
Health Hazards Acute and Chronic:METHANE IS NONTOXIC. IT CAN, HOWEVER,
    REDUCE THE AMOUNT OF OXYGEN AVAILABLE TO SUPPORT LIFE. EXPOSURE TO
    VERY LOW CONCENTRATIONS OF O XYGEN, UNCONSCIOUSNESS AND DEATH MAY
    OCCUR WITHOUT WARNING.
Explanation of Carcinogenicity:NO INGREDIENT OF A CONCENTRATION OF 0.1%
    OR GREATER IS LISTED AS A CARCINOGEN OR SUSPECTED CARCINOGEN.
Effects of Overexposure:INHALATION: HIGH CONCENTRATIONS OF METHANE SO
    AS TO EXCLUDE AN ADEQUATE SUPPLY OF OXYGEN TO THE LUNGS CAUSE
    DIZZINESS, DEEPER BREATHING DUE TO AIR HUNGER, POSSIBLE NAUSEA, &
    EVENTUAL UNCONSCIOUSNESS.
Medical Cond Aggravated by Exposure:NONE SPECIFIED BY MANUFACTURER.
*  First Aid Measures  *
First Aid:INHALATION: CONSCIOUS PERSONS SHOULD BE ASSISTED TO AN
    UNCONTAMINATED AREA AND INHALE FRESH AIR. QUICK REMOVAL FROM THE
    CONTAMINATED AREA IS MOST IMPORTANT. UNCONSCIOUS PERSONS SHOULD BE
    MOVED TO AN U NCONTAMINATED AREA, GIVEN MOUTH-TO-MOUTH
    RESUSCITATION & SUPPLEMENTAL OXYGEN. FURTHER TREATMENT SHOULD BE
    SYMPTOMATIC & SUPPORTIVE.
*  Fire Fighting Measures  *
Lower Limits:5%
Extinguishing Media:WATER, CARBON DIOXIDE, DRY CHEMICAL.
Fire Fighting Procedures:IF POSSIBLE WITHOUT RISK, STOP FLOW OF
    METHANE. FROM A SAFE DISTANCE USE WATER SPRAY TO COOL SURROUNDING
    CONTAINERS UNTIL WELL AFTER FIRE IS OUT.
Unusual Fire/Explosion Hazard:SHOULD FLAME BE EXTINGUISHED & FLOW OF
    GAS CONTINUE, INCREASE VENTILATION TO PREVENT FLAMMABLE OR
    EXPLOSIVE MIXTURE FORMATION. CYLINDERS MAY VENT OR EXPLODE.
*  Accidental Release Measures  *
Spill Release Procedures:EVACUATE ALL PERSONNEL FROM AFFECTED AREA. USE
    APPROPRIATE PROTECTIVE EQUIPMENT. IF LEAK IS IN USER'S EQUIPMENT,
    BE SURE TO PURGE PIPING W/INERT GAS PRIOR TO ATTEMPTING REPAIRS. IF
Neutralizing Agent:NONE SPECIFIED BY MANUFACTURER.
*Handling and Storage  *
Handling and Storage Precautions:STORE IN COOL/DRY/WELL-VENTILATED AREA
    OF NON-COMBUSTIBLE CONSTRUCTION AWAY FROM HEAVILY TRAVELED AREAS &
Other Precautions:STORE CYLINDERS UPRIGHT/FIRMLY SECURED TO PREVENT
    FALLING. FULL & EMPTY CYLINDERS SHOULD BE SEGREGATED. DON'T SMOKE.
    USE ONLY IN WELL VENTILATED AREAS. DON'T DRAG/SLIDE/ROLL CYLINDERS.
    USE SUITABLE HA ND TRUCK TO MOVE CYLINDERS.
