Some time ago, I witnessed a unit startup. The routine checks for the unit were completed, but one solenoid valve wasn’t activated, which caused the unit to start and then shut down again. I would like to ask Haiyou: how is it determined in normal situations?
The control room staff should conduct on-site verification and create a startup checklist that lists the inspection items for the key valves of the equipment. The control room staff shall carry out inspections on site, confirm everything, and sign off; the equipment can only be started once all requirements are met. Even if it shuts down due to some issue, there will be records available for reference, which helps to clarify responsibilities and ensures that no one is left unaccountable. This also enhances safety
