When asbestos was discovered in the United States and Canada in the late 19th century, it was quickly adopted into construction efforts. Its resistance to heat and corrosion damage made it a desirable substance. The minerals’ natural resistance to fire and abrasion was used until the early 1970s, when the full extent of asbestos danger was discovered. Today, we understand how dangerous asbestos exposure can be. OSHA and the EPA have placed strict guidelines in place around asbestos awareness training that employers are obligated to implement for the safety of their workforce.
