You’ve all heard it. In fact, I am guessing most of you have it memorized by now: 2.3 million workers are exposed to respirable crystalline silica in their workplaces. This includes 2 million construction workers who drill, cut, crush, or grind. When the deadline rolled on Saturday, September 23 (I still don’t understand why the deadline came on a weekend, perhaps someone can email me about that deadline), construction firms were expected to be ready for the new OSHA (Occupational Safety and Health Admin.) mandate.
