I went to school and one of my buddies i had lunch with stopped to talk about what happened at work that day. He's a smart, hard worker with alot of hustle. He did alot of work for this one contractor in this big dirty building. He looked like he'd been sweeping chimnies all day. He brought up a concern for the contractors to consider, a small handful of dust, and said it needed to be tested to see if it was asbestos. The contractor laughed and blew the pile into his face and said "GET BACK TO WORK, theres no way thats asbestos. thats not the first time someone tried to trick me like that." So, sorry to all the construction workers out there working on old buildings who's health is not being taken very seriously
