Rank: Super forum user		Are you spraying or applying by roller or brush? Are you going to carry out air monitoring to confirm compliance to WELs'? If not, why are you so much focussed on WELs when you could be simply focussing on the Principles of Control http://www.hse.gov.uk/co...onstruction/painting.htm

The first thing to do is look at % and see if you can even get near a WEL for the use (see above comment) Also don't forget LEL and UELs if it's flammable If you do need to monitor, or for help with basic surveys see : http://www.hse.gov.uk/pubns/priced/hsg173.pdf
