In the past decade, six U.S. States (Massachusetts, Connecticut, Rhode Island, New Hampshire, New York, and Missouri) have passed laws requiring workers employed on publicly funded construction projects to receive a standard 10-hour OSHA-authorized hazard awareness training course prior to work. One state, Nevada, has mandated “OSHA-10” for all construction workers. The researcher investigates the effect of these laws on reported construction injury and fatality rates with a model that seeks to control for relative union density and the impact of the 2008-2009 recession.
