Right, it's the tubing cement. I'm okay with thin cement, but the second the thick cement jar opens I'm done for. I can't be an audiologist if I can't work with tubing cement...
Sure you can. When you have your own practice, you will have to install an extractor hood, like they have in chemistry labs and kitchens. Or just avoid thick cement. I am not even sure I have encountered it. Do you mean Duco?
