A 67-year-old California man fell off a 500-foot cliff while trying to rescue his dog, authorities said. The Golden Gate National Park ranger said the man’s dog got away from him, and when he tried to go after it he slipped to his death. Long after the fatal fall, the man’s dog continued pacing and barking on a perch, as if sensing something was wrong.

On February 12, the federal government announced a multimillion-dollar settlement with Shell Oil over a long list of air pollution violations at a petrochemical refinery in Norco, Louisiana.

OSHA has launched an investigation into what caused a drilling rig explosion this past January that left five dead in Pittsburg County, Oklahoma. An Oklahoma Corporation Commission investigation report said authorities learned at 8:45 a.m. Monday, January 22, that the well was on fire from an uncontrolled gas release. The report recommended that the operator should kill the well with heavy drilling mud, make sure it is stabilized with mud and cement plugs, and take soil samples by Feb. 23.

Nurses who rate themselves as being in suboptimal health are more likely to make medical errors, reports a study in the February Journal of Occupational and Environmental Medicine. Nurses who feel their workplace provides good support for wellness perceive their health as better—and thus may be less likely to make errors, suggests the study by Bernadette Melnyk, PhD, RN, of The Ohio State University College of Nursing and colleagues.

The National Transportation Safety Board’s (NTSB) “most wanted” aviation safety improvement has yet to be resolved, but the collaboration that will lead to that is taking place.

OSHA last week launched a regional Focus Four Campaign in the Mid-Atlantic States to address the four leading causes of fatal injuries in construction. Throughout the month of March, the campaign will use toolbox talks and outreach events to focus on electrical hazards.

A new report from the Campbell Institute indicates not all employers are getting worker wellbeing right, and it could be affecting the sustainability of their business. While many organizations today are focused on wellbeing programs that tackle smoking cessation, weight loss or nutrition – not bad programs in and of themselves – the Campbell Institute report indicates a more multifaceted approach to worker wellbeing can lead to sustainable, and even increased, employee health.

OSHA has delayed the enforcement date for its final rule on occupational exposure to beryllium in general, construction, and shipyard industries until May 11, 2018 – a move that angered the United Steelworkers (USW) union. The start of enforcement had previously been set for March 12, 2018. The agency said the 60-day delay will “ensure that stakeholders are aware of their obligations, and that OSHA provides consistent instructions to its inspectors.”

An international study suggests other aspects of the diet may not offset the harmful effect of sodium on blood pressure. The study, published in the American Heart Association’s (AHA) journal Hypertension, also reaffirms the need for widespread sodium reduction in the food supply. Researchers reviewed data on sodium intake and intake of 80 nutrients, such as proteins, fats, vitamins, minerals and amino acids, that may relate to blood pressure in 4,680 women and men (ages 40-59) in Japan, People’s Republic of China, the United Kingdom and the United States participating in the INTERMAP study.
