Safety at Work

This doesn't seem to be of much importance. I have seen a man lower himself over the side of a block of flats on a rope to paint the outside of the building. No hard hat and flip flops! Here is a picture (taken on Sunday - so no workmen) of the walkways between the construction of two blocks of flats being worked on at the same time. I have seen the workmen walking across these. Again no hard hats or any sort of safety procedures.
