Posted By Larry Meager I need some advice on the management (and the effect) of reflected light and heat when installing a steel roof. Does any one know of guidance notes, case studies, standards etc. In anticipation Thanks for your help. Larry Meager Melbourne Aust.

Posted By Jonathan Breeze Uh, Paul, in this case the source is the sun, what do you suggest... a giant satellite perhaps? Seriously, Paul has a point though. You could try covering the reflective roof with a tarpaulin or similar although make sure you don't add other hazards in the process (trip hazards or covered fragile areas spring to mind). Alternatively you could consider providing staff with sunglasses, a T-shirt & sun cream (PPE) to minimise exposure to solar radiation although you will become responsible for making sure staff wear the kit provided (of course if you don't provide the required PPE for the job you're probably breaking the law anyway). Whatever you choose, it should be informed by your risk assessment. There is a document available in the UK called Health & Safety in Roof Work (HSG 33) which may be available on the net, but I can't help you with Australian law.

Posted By Jonathan Breeze The more astute of you will have realised the assumption was equally on my part. At no point does Larry actually state what the source of UV radiation is. Paul has assumed it is from e.g. welding, I have assumed it is from sun exposure. Apologies one and all.

Posted By Steve Sedgwick I would guess there should be some good industry guidance on this. Even in our British summer it would be far too hot to work on a steel clad roof for long. I have just been watching construction workers opposite my hotel in Portugal, in the heat of the day they try to do jobs in the shaded areas or inside. Work in the sun exposed areas are done early morning or evening time. Steve
