From my story at C&EN:
American Chemical Society journals will have a new safety reporting requirement starting in 2017: Authors must "address and emphasize any unexpected, new, and/or significant hazards or risks associated with the reported work," says an ACS Central Science editorial describing the change (2016, DOI: 10.1021/acscentsci.6b00341).
ACS Publications editors and staff took a closer look at how the journals addressed safety after a "confluence of events" that included high-profile accidents and a survey of safety policies of chemical journals (J. Chem. Health Saf. 2016, DOI: 10.1016/j.jchas.2015.10.001), says Sarah Tegen, vice president for global editorial and author services at ACS. ACS also publishes C&EN. Previously, individual journals set their own safety policies.
