I think this is where the discussion becomes more interesting. NwR Safety Central infers that PJW's definition could be seen as not correct on the basis of the "unsafe" statement:
However, everything PJW states is fundamentally correct! So could we deduce that choosing a more black and white example could provide a more robust, less subtle, answer? Possibly, but would stating our assumptions and definitions of what we deem a WSF to be before answering the question avoid the examiner interpreting the justification in a way we didn't intend and be a useful exam technique? Yes to the second question, perhaps to the first!
More opinions most welcome on this subject though.
Quote:Wrong Side Failure WSF
(i) Wrong Side Failure: something which fails in an unsafe condition (ii) Wrong Side Signalling Failure. A wrong side failure occurs when equipment or a system does not fail safe. In other words, a failure occurs which could lead to an accident.
