I’ve been grinding concrete and terrazzo for over 20 years. In the last few years silica has become way more of a focus. Crystalline silica to be more specific. Every year I have to do a fit test for a P100 respirator and every 3 years a physical and pulmonary test. I have had swollen nodes like you’re talking about but haven’t in a while, maybe the proper respirator and no more facial hair is working. If your shop has that much dust to effect you like that, they should absolutely be suppling PPE and training. Especially if you have any engineered stone in there, almost all crystalline silica in that stuff. If the company is not, I would report them to OSHA and look for a new job. Silicosis is the number one killer in the trades and should be taken seriously.
