Dust management in a High School shop
I will be taking over a high school woodshop program next semester, and I'm thinking a lot about trying to keep my students safe and healthy. The shop has a large dust collection system in place and all the major stationary tools are hooked up. But the handheld orbital and belt sanders are not currently hooked up to a collector or extractor or shop vac w/cyclone, etc. So it gets really dusty in there with several students sanding their projects. I don't think it's something the current teacher was really concerned with, but as I've been in there helping out here and there this semester, I'll walk out and my throat will feel rough and coated so I really think I need to deal with it once I'm in there fulltime. I'm wondering if I should look into buying extractors to use for sanding or if I should have all the kids wear masks, or if I should do both. I'm trying to keep things as simple and as cheap as possible. My primary concern is keeping lungs clean, not the shop. Obviously I know that extractors AND masks would be ideal but I'm wondering if just going with masks would be good enough if I'm okay with having to sweep up more often. I thought I'd get some opinions to help me before I spend what little budget I have.
