Lead is a dangerous substance, with both acute and, particularly, chronic health problems associated with exposure to it. It is present in EOL electronic equipment - in many circuit boards still and, particularly, in CRT glass. That means it is present - and presents potential exposure dangers - in electronics recycling facilities.
Recent preliminary research into human exposure to lead in certain types of electronics recycling facilities indicates a need to be proactive in identifying and limiting such exposure. This is particularly true in facilities that shred or process CRT glass or shred circuit boards containing lead solder. In such facilities, air monitoring and, importantly, bio-monitoring are key to identifying potentially dangerous lead exposure levels. Regarding bio- or blood monitoring, it may be a relatively simple matter to do it as an additional component of a drug-testing program.
Talk to a certified industrial hygienist about what types and frequencies of monitoring are appropriate. And if monitoring results suggest action be taken, get recommendations for him or her regarding best practices that make sense in the particular situation. He or she may recommend anything or everything from training and personal hygiene such as changing clothes and washing hands, to specially designed ventilation, protective suits, and respirators.
Dangerous lead exposure levels must be taken seriously. If there is a chance they exist in a facility given the materials and processing involved, there are compelling moral and financial reasons to effectively monitor for them. And if they are found to exist, the same reasons hold for effectively addressing them.
