It is always worth taking precautions, even with a fan that is almost sucking the lead out of the pot we wear masks (designed for fumes not dust). It is the lead oxide which is produced during the melting process and when impurities are removed by fluxing that is the main problem.
Despite all the problems and sweat, casting is a great pastime.
