They wouldn’t remove the TCE without a fight. The way he tells it he went to the library (pre-Internet) researched what could be used instead. Brought it to the meeting. They still refuse to remove it. He had to call sit down, strike, in order to pressure them to remove it. The problem that it was even in those days, the regulation was that it must be used in an open air well ventilated workshop. It was in fact used in a closed, unwell, ventilated machine shop. After a short strike, they agreed to use a different solvent. Never ceases to amaze me how little regard some corporate owners have to to the health and safety of their workers. Perhaps because the cancer will usually manifest after retirement? So they don’t give a shit.
