The Workers’ Compensation Research Institute (WCRI) will host a 30-minute webinar on Thursday, October 30, 2025, at 2:00 PM ET, highlighting findings from WCRI's latest report, Impact of California’s Heat Standard on Workers’ Compensation Outcomes.

During the webinar, Sebastian Negrusa, WCRI vice president of research, will address key questions:

• How large is the impact of the heat standard on injury frequency in industries with outdoor heat exposure?
• Does the impact of the heat standard increase with higher temperatures?
• Does the impact of the heat standard vary for younger versus older workers?

Previous WCRI research found that excessive heat not only causes heat-related illnesses such as heat exhaustion but also impairs judgment and perception, increasing the risk of accidents such as being struck by machinery. Heat-related illnesses are 11 to 18 times more frequent on days above 95°F compared with days between 75 and 80°F, yet they represent 20 to 25 percent of all injuries attributable to heat.
