Oxygen is not flammable in itself but supports combustion. Oxygen can react with most materials. Care must be taken in the ion of equipment and materials, which need to be oxygen compatible and free from contaminants. The main contaminants to be avoided and/or eliminated are hydrocarbon oils and greases, which are easily combustible and particulate matter, which can easy ignite or cause ignition.

Specific and meticulous methods and apparatus for cleaning, inspecting, and packaging the Expansion Joints intended for service in O2 have been used and a set of high performance Expansion Joints have been successfully delivered.
