Heat stress illness among United States Postal Service employees in Las Vegas has resulted in a $129,336 fine against the USPS.

An OSHA investigation revealed that at least four USPS employees at the Silverado Station branch in Las Vegas received treatment for heat-related illness this year, including one hospitalization. OSHA cited the USPS for failing to protect letter carriers working in extreme heat, lacking sufficient heat control measures, and having inadequate procedures for contacting supervisors when employees experience heat-related symptoms.
