7.2 Shutdown
7.2.1 Measures to be taken for shutdown
During prolonged shutdown periods, ensure that the following conditions are met:
1. Drain fluids which change their physical condition due to changes in
concentration, polymerisation, crystallisation, solidification, etc. from the piping.
2. If required, flush the piping with the valves fully opened.
