safety

I always fear for workmen perched at great heights and doing the most dangerous things. Are there any safety regulations around? This poor guy has been working for the past three days cleaning the building next to mine and I suppose the only saving grace is that water has to be used rather than the dry sprays, but everywhere is still covered in a horrid fine sand. No mask, just goggles and a shmagh. and he probably gets just a pittance for what he is doing. T
