Posted By Andrew Shaw Hi, I'm well out of my comfort zone here so any help gratefully received. We have recently acquired a Joinery Workshop that uses a spray booth for the application of Varnishes / Lacquers / Paints etc. The booth does have exhaust ventilation, which is used, and the operatives do have half face twin cartridge RPE available, which they also use. I have printed off some of the MSDS of the many products they may use and many suggest using Anti-aerosol filters P2 & Anti-gas filters A2. I'm struggling to find clear info / advice as to what level of protection is required for the hazardous substances we're dealing with (xylene, toluene, ethanol, methanol, acetone and various iso-butyl....) and which products will provide that level of protection. I'm assuming an APF of 40 will be acceptable but I'd like to know the exact numbers so I can be sure. Any good web sites or documentation you could recommend would be gratefully received.

Posted By Paul Leadbetter Andrew Before deciding on appropriate RPE, you need to know what level of airborne solvents you are trying to protect against. I am an occupational hygienist and would be happy to talk through your concerns if you call me on 01905 353500. Paul
