=======================  First Aid Measures  =======================

First Aid:SKIN: IMMEDIATELY WARM FROSTBITE AREA W/WARM WATER (NOT
    >105F). REMOVE CLOTHING WHILE SHOWERING W/WARM WATER. INHALATION:
    REMOVE TO FRESH AIR. GIVE ARTIFICIAL RESPIRATION/OXYGEN IF
    NECESSARY. EYES: FL USH W/WATER FOR AT LEAST 15 MINS. OBTAIN
    MEDICAL ATTENTION IN ALL CASES. SEE SUPPLEMENTAL INFORMATION FOR
    NOTE TO PHYSICIAN.

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

Extinguishing Media:USE MEDIA APPROPRIATE FOR SURROUNDING FIRE. IF
    CONTAINERS ARE LEAKING REDUCE VAPORS W/WATER SPRAY OR FOG.
Fire Fighting Procedures:EVACUATE ALL PERSONNEL FROM DANGER AREA. WEAR
    SCBA/PROTECTIVE CLOTHING. COOL CONTAINERS W/WATER SPRAY FROM
    MAXIMUM DISTANCE/MOVE CONTAINERS. SHUT OFF LEAK.
Unusual Fire/Explosion Hazard:OXIDIZING AGENT MAY ACCELERATE
    COMBUSTION. FLAMMABLE MATERIAL MAY CAUSE FIRE/EXPLOSION. CONTAINER
    MAY RUPTURE DUE TO HEAT. VAPORS TRAVEL TO IGNITION SOURCE.

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

Spill Release Procedures:EVACUATE PEOPLE/USE SCBA. REDUCE VAPORS
    W/FOG/FINE WATER SPRAY. SHUT OFF LEAK SAFELY. VENTILATE AREA/MOVE
    LEAKING CONTAINER. VAPORS SPREAD. BEFORE ENTERING CONFINED AREA,
    CHECK ATMOSPHERE W/APPROPRIAT E DEVICE. BLOW DOWN SYSTEM BY
    VENTING.

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

Handling and Storage Precautions:MOST CONTAINERS ARE PROVIDED
    W/PRESSURE RELIEF DEVICE DESIGNED TO VENT CONTENTS WHEN EXPOSED TO
    ELEVATED TEMPS. CONFIRM PLASTIC COMPATIBILITY.
Other Precautions:LIQUIFIED OXIDIZING GAS UNDER PRESSURE. USE
    PIPING/EQUIPMENT ADEQUATELY DESIGNED TO W/STAND PRESSURES TO BE
    ENCOUNTERED. CLOSE VALVE WHEN NOT IN USE/WHEN EMPTY. READ ALL
    LABELS OF PRODUCT. WHEN LIQUIF IED GASES ARE MIXED, COMBINED
    PROPERTY.

    INADEQUATE. USE ONLY IN CLOSED SYSTEM CONDITIONED FOR NITROUS
    OXIDE.
Protective Gloves:PREFERRED FOR CYLINDER HANDLING
Other Protective Equipment:METATARSAL SHOES FOR CYLINDER HANDLING,
    PROTECTIVE CLOTHING WHERE NEEDED
Supplemental Safety and Health
NOTE TO PHYSICIAN: NITROUS OXIDE MAY CAUSE VITAMIN B12 DEFICIENCY.
    MEGALOBLASTIC ANEMIA/NERVOUS SYSTEM DISORDERS CAN OCCUR AS RESULT
    OF THIS CHEMICALLY INDUCED DEFICIENCY. ANESTHETIC GASES/NITROUS OXI
    DE MAY SUPPRESS IMMUNOLOGICAL FUNCTION WHEN GIVEN FOR ANESTHETIC
    PURPOSES. THEY REDUCE RESISTANCE TO INFECTION.
