Can anyone provide details of companies that undertake air testing/monitoring whilst operatives are preparing previously painted window, I am planning to use methods suggested by the British Coating Federation. Also we need to carry out health surveillance and have been told that there is a swab type test that can be undertaken rather than blood test, again any help on these item would be most appreciated. Many Thanks PaulR

Have you looked on the HSE website under both COSHH and health surveillance, they have various documents covering monitoring exposure to lead, which are useful and will give you the guidance you need.
