Anyone heard anything about the new regs on the use disc cutters, all have to have water feeds to stop the emitance of silica dust.

Ineptocracy

(in-ep-toc-ra-cy) €“ a system of government where the least capable to
lead are elected by the least capable of producing, and where the
members of society least likely to sustain themselves or succeed, are
rewarded with goods and services paid for by the confiscated wealth of a
diminishing number of producers.

No.

Likewise. However, stone saws (mine anyway) have provision for water to
be fed to the blade.

Fine for block cutting but my suspicion is that it degrades modestly
priced diamond blades when cutting concrete.

Some 'professionals' I've seen recently were making such a half-hearted
attempt with the water I don't know why they bothered. Passers-by still
had no option but to breathe in the dust.

Changes to approved methods of roof tile cutting to protect against silica dust.
From 1st October 2012, contractors will no longer have the option of using a cut-off saw to dry cut valley tiles.

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 Respiratory Protection Equipment (RPE) will also be expected. This is in line with the controls currently in use for cutting tiles in other sections of the roof.

These changes result from recent work by HSE to monitor the exposure of roofers to silica dust which showed that the levels of silica dust created when dry cutting valley tiles are much higher than published safety limits. This means that a high standard of control is needed to reduce the risks from silica dust.

Silica is a natural mineral present in large amounts in many construction materials like concrete roof tiles. Common tasks such as cutting break the silica into very fine dust (Respirable Crystalline Silica or RCS). Regularly breathing in RCS can cause serious lung disease like silicosis and lung cancer.

Seems popcorn can also cause serious lung disease.

So don't go to the cinema at the weekend after a hard week of tile
cutting...
