I virtually always use a Moldex dust mask with the exhaust port or AO respirator.

My trick (more for the finished product than safety) is to use Thin-x and emery paper & then steel wool to sand & polish Rosewood. I wear exam gloves to minimize the fluid getting on my skin. Works wonders, and no airborne dust.

Never had a reaction to wood - not even Cocobolo - but get me within shouting distance of Poison Ivy and I become a 1950s B movie monster, complete with oozing sores everywhere. I avoid Goncalo Alves for this reason. It and some other species are in the P. I. family.

It'd freeking kill me to have that happen from working with Rosewood. I agree. Take precautions - "Uuuuuuuse the maaaaaaaasssk, Luuuuuke!"
