Wetting the lead keeps the dust down. A de lash needle is a GMP product you pull in front of the lasher. It will ball the wire up nicely, better than a rope and a snap. https://www.gmptools.com/b-lashing-wire-remover/ I worked for a RBOC for thirty years as a lineman and splicer and have handled a lot of lead. I am fine, just don't eat it. The company did a study of line crews and splicing crews for exposure to lead, and the levels were well below OSHA standards. Wear gloves, a dust mask if wanted, and you should be just fine.
A real good question. There is nothing wrong with providing a safe work environment for yourself and other crew members.
