Safety considerations for those carrying out inspections
Any employees or volunteers carrying out inspections around the boundary walls which are above their head height or exceed 1.2 metres in total height should ensure that they are wearing suitable PPE (helmet, safety boots) and should ensure that they maintain a proximity which exceeds the approximate height of the wall + 2 metres to ensure that you are a suitably safe distance from the wall structure.
If you consider the wall to be in a perilous condition and foreseeable failure is likely, please do not approach the structure. Use equipment with a suitable zoom function to capture images from a safe distance.
