Pure O2 at atmospheric pressure is dangerous when combined with a ‘fuel’ such as hydrocarbon oil vapor at a mechanical pump’s exhaust valve. It is strongly recommend that if any flow of pure O2 is injected into the chamber, the mechanical pump’s fluid should be Fomblin and, wherever possible the O2 at the exhaust be quickly diluted with N2 (either through the pump’s ballast entry or by injection at the pump’s exhaust port).
