Jim,
All that being said and nicely translated....I found the practice, of an operator we both worked for in the past, of doing an inspection of all decks and markings upon start of an operation or when new decks were put into operation worked to prevent any such problems.
As others have mentioned, monitoring the condition of the decks and reporting as a standard procedure by the Safety Officer, Training Captain, Captains, and Chief Pilot works towards discovering problems. A good Safety Program will also have a system that follows up on reported problems and ensures hazardous issues are resolved, shutting down decks if necessary until corrective action is taken.
