![]() What makes a Lubricant Oxygen Compatible? What does "Oxygen Compatible" mean? Pg 15 Material compatibility is where material can co-exist with elevated O2 concentrations AND a potential source of ignition with out flashing. Pg 14 1) Mechanical Impact - Valve chatterĢ) Thermal Runaway - Combustion of the compressors oil if it exceeds the flash pointģ) Chemical Reaction - Ignition in the filtration towers 3 conditions of "Oxygen Serviced"ģ) Oxygen compatible Name 8 things that are design features for Oxygen Systems.Ħ) Short pipes on teflon lined braid hosesħ) Filters in place, ahead of high velocity componentsĨ) Guages installed in protected places. How do you prevent Sparks/Arcs?Static? Pg14 Ensure proper functioning and grounding List 3 more igintion mechanisms? ![]() Caused by Powered systems, motors, switches and static discharge. Pg 14 Electrical discharges that can ignite an O2 rich environment. How do you prevent "Frictional Heating"? 1) VISUALLY inspect all valves.Ģ) Use 10 x microscope to look for fibers, shavings.ģ) Listen for gas escaping a closed valve.Ĥ) Test for Leaks. Pg 13 Frictional heating is concentrated localized heating caused by FLOW friction. ![]() The impact changes Kinetic to Heat How do you prevent "Particle Impingment"? Pg 12 1) Use Monel or brass within 10 x the diameter of hose.ģ) Beware when installing system, teflon/burs.ĥ) Purge all valves with inert gas. Pg 12 When heat is generated as particles strike a material with sufficient velocity to ignite the particle or material. ![]()
