Thread: Melting Lead - fumes

I would suggest that a proper P100 mask is the best protection but an extractor would seem better than nothing.

Some dust will get past the filters. But removing the filters to clean from a range hood won't necessarily disturb settled dust past them. Wearing gloves and mask to clean would certainly be the go. I have a near new mask that has the trade quality rubber nose cup and side replaceable filter elements. Has elements for paint spraying and shop dust etc at the mo. I need to source new elements suitable for chemical dust/fumes as @No.3 recommends.
