not saying to much about safety since I do the same things, but here just those workers not wearing masks as the tvs are smashed with loaders or falling on each other on conveyers and so forth though that video would make the epa and osha scream here. here in the us we have a limit for arsenic and lead in glass beads we use in pavement markings and beds that is much lower than other countries mainly because of food production along these major roadways.
there is still a large market for leaded glass doors and windows but here also in the usa we have better ways of recycling lead glass even machines that are completely sealed that process whole tvs and though a series of steps claim most lead kind of like battery recycling
