Unknown leaks are also dangerous!

In a petrochemical plant in Europe, an incident has been reported where a carcinogenic chemical was emitted without being noticed for two months as a valve was left inadvertently open. Approximately 28 MT of the chemical was released into the atmosphere in a period of two months. The plant in question has very good PSM system. But the release of a carcinogenic chemical over a period of 2 months was not detected and has been treated by authorities as a Major Accident.

Do you have proper checks after a  plant startup whether all vents are closed?
