South Korean companies are extending rest periods, reshaping work schedules, and providing cooling equipment as record heat raises workplace injury risks. Yangsan recorded a national high of 42.5°C, while Seoul remains under the highest-level heatwave warning. Data from Representative Kim Wi-sang shows 195 heat-related occupational accidents between 2022 and June 2026, including 20 deaths. Thirteen cases, four fatal, were already recognized in 2026 before the usual July-August peak.
