Tank Changing Procedures
WARNING: Oxygen systems must be handled with CAUTION. Spontaneous combustion may occur
if oxygen comes into contact with grease or oil. Ensure that hands, gloves, clothing and tools are
kept clean and free of oil and grease. Be careful not to introduce dust or other contaminants into
the system when changing tanks. Failure to comply with the procedure may be hazardous
WARNING: Fire Hazard. DO NOT permit smoking, or any other source of ignition in area where
the manifold is located, or near the relief valve vent outlet. Be certain that all connections are free
of dirt, grease, and oil. These substances burn with great intensity in air enriched with oxygen, or
nitrous oxide and some gas mixtures
