A good source that treats oxygen safety in detail (GOX, LOX, handling, storage materials compatibility, cleanliness, cleaning procedures,..... "NASA Glenn Safety Manual, Chapter 5 -- Oxygen Propellant," July 1997, see at: http://www-osma.lerc.nasa.gov/lsm/lsm5.htm In section 5.10.5 there is a description of interesting tests with high pressure GOX at high flow velocity in the presence of particulate contaminations. >From these tests come recommendations of max velocities in systems that handle GOX.
