Fracking workers exposed to dangerous amounts of benzene, study says

Some workers at oil and gas sites where fracking occurs are routinely exposed to high levels of benzene, a colorless gas that can cause cancer, according to a study by the National Institute for Occupational Safety and Health. The agency, which is part of the Centers for Disease Control and Prevention, recommends that people limit their benzene exposure to an average of 0.1 of a part per million during their shift. But when NIOSH researchers measured the amount of airborne benzene that oil and gas workers were exposed to when they opened hatches atop tanks at well sites, 15 out of 17 samples were over that amount. Workers must open these hatches to inspect the contents of these tanks,...
