Governments worldwide are implementing heat protection laws as 2.4 billion workers face extreme temperature exposure and 19,000 die annually from heat-related workplace injuries, according to a World Health Organization and World Meteorological Organization report. Japan imposed $3,400 fines for employers failing to provide cooling measures when wet-bulb temperatures reach 28C. Singapore mandated hourly temperature sensors at large outdoor sites and requires 15-minute breaks every hour at 33C wet-bulb readings. Southern European nations ordered afternoon work stoppages this summer when temperatures exceeded 115F across Greece, Italy and Spain. The United States lacks federal heat standards; only California, Colorado, Maryland, Minnesota, Nevada, Oregon and Washington have state-level protections. Boston passed requirements for heat illness prevention plans on city projects. Enforcement remains inconsistent -- Singapore inspectors found nearly one-third of 70 sites violated the 2023 law. Texas and Florida prohibit local governments from mandating rest and water breaks.Read more of this story at Slashdot.
