As with all matters H&S dust in construction is not a one size fits all.

Your measures would not look out of place in a major road building project but for a refurbishment of a tower block I am struggling to see the validity of a road sweeper.

Other measures with relevance to specific activity would include on-tool extraction (drills, saws, sanders), alternative methods (moulding holes in a new concrete pour rather than drilling the formed concrete) and off-site kits (all cutting and hole forming is conducted in a factory rather than at site where LEV is often impracticable). There are also "on-tool" water supression systems for items such as diamond saws.

One you do seem to have overlooked common in quarrying is a wheel wash to keep the dust contained at site rather than escaping on to the public highway.

Hi Karan

Not clear from your Forum profile as to what geography (or geographies) you work in.

However, in the UK many of the issues that result in both respirable and non respirable dust on construction sites COULD be best mitigated before a project ever reaches site, if those with front end duties under the "CDM" Regulations fully did what they should.

NOTE - similar legislation to CDM in place in EU Member States.

So, as example a designer could consider building components that are consistent with commonly made products, thereby avoiding the need for on site cutting (or at the very least reducing the amount of cutting that would be needed).

Roundtuit has pointed to other examples of how to make the construction site an inherently better place to work.

Problem is that the front end duty holders - particularly Clients and Designers and under the current iteration of CDM the "Principal Designer" are rarely in the spotlight. 

[This is borne out by the cnforcement statistics for CDM in Great Britain - HEAVILY skewed to action against Contractors for what happens once a project reaches site]
