Changes to approved methods of roof tile cutting to protect against silica dust
From 1st October 2012, british contractors will no longer have the option of using a cut-off saw to dry cut valley tiles. In a bid to reduce the risks from silica dust, industry has supported changes to working methods which mean that, should a cut-off saw be used for cutting valley tiles, water suppression as well as the correct RPE will also be expected. This is in line with the controls currently in use for cutting tiles in other sections of the roof.
Contractors do have the option of using other methods as long as they can demonstrate these are equally as effective at controlling the silica risk.
