P-5: Care of High Pressure Cylinders for Underwater Breathing

Abstract

Steel and aluminum alloy compressed gas cylinders used for underwater diving service in self-contained underwater breathing apparatus (SCUBA) are exposed to extremely harsh conditions. Corrosion caused by seawater can weaken cylinders and residue from corrosion can clog valves and regulators resulting in reduced or blocked airflow. Proper maintenance ensures a long life, satisfactory service, safety, and reliability for cylinders used in underwater diving.

This publication provides recommendations for the care of high pressure cylinders for underwater breathing. In recognition of the extreme conditions to which compressed gas cylinders used for underwater diving service are exposed.

This publication is not intended to give detailed or specific recommended procedures for cleaning, paint stripping, inspection, valve maintenance, etc., that would be better provided by the cylinder manufacturer or distributor of the compressed gas underwater equipment.

This publication also recognizes that other types of SCUBA do exist. Closed circuit oxygen and mixed gas systems have special cylinder requirements. All requests for information concerning such equipment should be directed to the cylinder manufacturer.
