Despite the fuss and emotion there is a real issue of principle involved. Safety is a risk management discipline. This means that you assess the likelihood of serious accidents occurring in a specific environment and if that is high, then you look at precautions that would prevent it.
The most dangerous thing you can do in safety management is follow a "tick box " approach, you must assess the specific risk in the specific context.
Hi Viz for Hi Viz sake suggests that we are in tick box not risk assessment mode.
