A method of preparing a system for a maintenance operation having first subsystem, a second subsystem, and a third subsystem separated by sealing blocks. To reduce the hazard risk, the step of removing gas from the second subsystem via a bleed conduit includes applying the sub-atmospheric pressure using a venturi-pump into which an anoxic gas to drive said venturi-pump is introduced to mix with and remove gas from the second subsystem, said venturi-pump having a maximum venturi ratio Mvr.
