Store in cool, dry, well-ventilated area away from sources of heat or direct sunlight. Do not allow areas where liquid cylinders are stored to exceed 125dF. Use a check valve or trap in the liquid cylinder discharge line to prevent hazardous backflow. Liquid cylinders should be stored upright and firmly secured to prevent falling or being knocked over. Keep oil, grease and all flammables away. Do not store with flammable gases.
Open oxygen valves slowly.
Use only DOT and ASME coded vessels. Use a pressure reducing regulator when connecting liquid cylinder to lower pressure piping or systems. Oxygen equipment must be cleaned and degreased for oxygen service. Close valve after each use and when empty. Liquid cylinders may not be refilled except by or with the consent of Liquid Carbonic.
