Occupational health and safety(OHS) is supposed to be a skill that anyone can obtain and apply but it is often complicated by experts. This is not to say that OHS is “common sense”. The notion of common sense is a nonsense.
Several years ago, Laurie Anderson performed in Melbourne, Australia. Her show was “Homeland” and the song that I most remember from her performance was “Only an expert“. There is a wisdom in the song that remains as topical as much now as it did when I heard it at the start of the international banking crisis and the US home lending crash. Anderson has been able to update the lyrics of the song to include the BP Gulf of Mexico oil spill.
