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.

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.

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 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.

Ventilation:LOCAL EXHAUST: ACCEPTABLE. MECHANICAL (GENERAL):
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.
