While OSHA intends to reduce the workplace limit for airborne silica by half, NSSGA officials say that OSHA's proposal will not improve worker health. Instead, the association says that it will cost employers millions of dollars each year and will lead to further workforce reductions in some industries. According to the NSSGA, the best scientific evidence indicates that the current exposure limit protects workers from silica-related disease when it is universally complied with, and universally enforced. Since the current limit took effect in 1971, silicosis-related deaths in the U.S. have dropped by more than 93 percent. What do you think about this potential regulation change?
