Power Tools Used with a HEPA Vacuum Are Becoming Standard What you can & can’t do What you can and must do is spray all work surfaces with water prior to sanding, scraping, drilling or cutting. Framing, door and window mouldings and other building components must be pried and pulled apart instead of pounded and hammered. Paint on components should be scored with a utility knife before pulling them apart. Since hand-sanding and scraping is slow, new power tools with HEPA vacuum attachments will probably have to be purchased by workers and contractors.
