There is a theory that it is cleaning up the workshop which disturbs a lot of the micro dust which is the most lethal. So, if possible sort out the extraction before cleaning up ! Using a vacuum or moving air extractor is the safest way of tidying up. Sweeping can be one of the least safe !
I use PP3 face masks if any, sometimes inside an Axminster blown air face shield. I have a Camvac vacuum system and a Record bagged extractor with a fine filter. Finally there is a Microclene air cleaner for "belt and braces". Without using the aforementioned along with skin cover to prevent absorption, I will get a blinding headache the day after turning yew, laburnum or english walnut. Be safe be happy.
