New Analysis Links Heat Standards to Worker Safety Amid Rising Temperatures

Last year was the hottest on record, and global warming is increasingly impacting worker safety, particularly in outdoor jobs. A new analysis published in Health Affairs highlights the importance of state-implemented outdoor heat standards in reducing worker deaths due to heat exposure.

The study focused on California, which established the nation's first outdoor heat standard in 2005. Researchers compared heat-related deaths among outdoor workers in California from 1999 to 2020 with neighboring states that lack similar regulations, such as Arizona, Nevada, and Oregon.

Following a significant enforcement enhancement in California in 2010, which included more workplace inspections and educational outreach, there was a statistically significant reduction in heat-related deaths, with estimates suggesting a thirty-three percent decrease.

Adam Dean, the study's author and associate professor of political science at George Washington University, states that the stronger enforcement measures were crucial in this decline. The report indicates that California had about 100 heat-related deaths annually from 2010 to 2020.

However, it also notes an alarming increase in outdoor worker deaths in neighboring states, where regulations are absent. The analysis found over six thousand heat-related deaths among outdoor workers across Arizona, California, Nevada, and Oregon during the study period, with Arizona reporting the highest number of fatalities.

Former OSHA deputy assistant secretary Jordan Barab emphasized that heat-related deaths are often undercounted and that many workers remain at risk, especially those with pre-existing health conditions.

The proposed federal heat standard by the Biden administration, expected to be finalized by the U.S. Occupational Safety and Health Administration next year, aims to mandate water, rest, and shade provisions at specific heat index levels.

However, experts like David Michaels, a professor at George Washington University's Milken Institute School of Public Health, highlight that while regulations are necessary, effective enforcement is critical for the standards to be successful.

There are significant concerns regarding the staffing levels at California's occupational safety agency, Cal/OSHA, which currently has ninety-five inspector vacancies. As temperatures continue to rise due to climate change, experts warn that enforcement of heat standards is vital to protect vulnerable workers from heat-related illnesses and fatalities.

The study underlines the life-saving impact of comprehensive workplace heat standards and underscores the urgent need for robust enforcement to safeguard worker health in the face of climate change.
