Extinguishing Media:NON-FLAMMABLE GAS MIXTURE. USE EXTINGUISHING MEDIA
APPROPRIATE FOR SURROUNDING FIRE.
Fire Fighting Procedures:EVACUATE ALL PERSONNEL FROM AREA. IF POSSIBLE,
SHUT OFF FLOW OF AIR WHICH IS SUPPORTING THE FIRE. IF POSSIBLE,
REMOVE CYLINDERS FROM FIRE AREA OR COOL WITH WATER. SCBA MAY BE
REQUIRED BY RESCUE WORKE RS.
Unusual Fire/Explosion Hazard:COMPRESSED AIR AT HIGH PRESSURE MAY
ACCELERATE COMBUSTION. MOST CYLINDERS ARE DESIGNED TO VENT CONTENTS
WHEN EXPOSED TO ELEVATED TEMPERATURES. PRESSURE IN A CYLINDER CAN
BUILD UP DUE TO HEAT AND IT MA Y RUPTURE IF PRESSURE RELIEF DEVICES
SHOULD FAIL TO FUNCTION.

Spill Release Procedures:EVACUATE IMMEDIATE AREA. SHUT OFF SOURCE OF
LEAK IF POSSIBLE. ISOLATE ANY LEAKING CYLINDER. IF LEAK IS FROM
CONTAINER, PRESSURE RELIEF DEVICE OR ITS VALVE, CONTACT YOUR
SUPPLIER. IF LEAK IS IN USER'S SYSTEM, CLOSE CYLINDER VALVE,
SAFETY VENT PRESSURE BEFORE ATTEMPTING REPAIRS.
Neutralizing Agent:NOT RELEVANT.

Handling and Storage Precautions:CYLINDERS SHOULD BE FIRMLY SECURED AND
KEPT AT ROOM TEMPERATURE (21C,70F). CYLINDERS SHOULD BE STORED IN
DRY, WELL-VENTILATED AREAS. DO NOT ALLOW THE TEMPERATURE WHERE
CYLINDERS ARE STORED TO EXCEED 1 25F (52C). PROTECT CYLINDERS
AGAINST PHYSICAL DAMAGE. FULL AND EMPTY CYLINDERS SHOULD BE
SEGREGATED.
Other Precautions:USE A FIRST-IN, FIRST-OUT SYSTEM. DO NOT DRAG, SLIDE,
ROLL OR DROP CYLINDERS. USE A SUITABLE HAND TRUCK FOR CYLINDER
MOVEMENT. NEVER ATTEMPT TO LIFT A CYLINDER BY ITS CAP. SECURE
CYLINDERS AT ALL TIME S. USE A PRESSURE REDUCING REGULATOR TO
SAFELY DISCHARGE GAS FROM CYLINDER.

Respiratory Protection:NOT REQUIRED.
