I can understand the concerns people have about asbestos, various chemicals etc, particularly if they have problems stemming from exposure, as seems to be the case with pansyface.
However, as the link to Bromley council website shows, there is absolutely minimal risk is sensible precautions are taken. The council wouldn't be providing that guidance if there was a health risk to DIY removal.
As for glyphosate, there are studies which indicate there are considerable health risks, and there are studies which contradict that. Call me cynical, but I suspect vested interests on both sides and a reality somewhere between the two opinions. Most gardeners only use weedkillers and other chemicals on an occasional basis which reduces the risk further. Until there is solid evidence of a real health risk I will continue using chemical controls, with or without a facemask.
