OSHA has issued serious citations against the employer of two employees who died from carbon monoxide (CO) exposure while being transported to a jobsite. The incident involving AJR Landscaping, Inc. occurred when a gasoline-powered lawnmower was started inside an enclosed company trailer. OSHA initiated an inspection after the Washington Township New Jersey Police Department notified the agency that the workers had died.

Although they compose only six percent of the total U.S. workforce, construction workers accounted for 36 percent of all occupational heat‐related deaths from 1992 to 2016 – and climate change may have something to do with it. That’s one of the key findings from new research from the Center for Construction Research and Training (CPWR).

Compared to small and "micro" businesses, larger companies have made more progress toward introducing the Total Worker Health (TWH) approach to worker health and safety, reports the August Journal of Occupational and Environmental Medicine. "Our results indicate a need for intervention research that specifically targets microbusinesses and small businesses, especially in light of the outsized health and safety risks encountered in these sectors of the economy," write Liliana Tenney, MPH, and colleagues of Colorado School of Public Health, University of Colorado, Aurora.

A pollutant associated with climate change is sulfur dioxide, a component of smog. Sulfur dioxide and closely related chemicals are known primarily as a cause of acid rain. But they also reflect light when released in the atmosphere, which keeps sunlight out and creates a cooling effect. Volcanic eruptions can spew massive amounts of sulfur dioxide into the atmosphere, sometimes causing cooling that lasts for years.
