OSHA heat emphasis updated
- OSHA revised its National Emphasis Program to better target inspections and outreach for indoor and outdoor heat hazards, effective April 10. - The update focuses enforcement on industries and workplaces where heat risks are most likely to produce severe injuries and illnesses. - The change increases the chance of targeted inspections and requires documented prevention controls rather than ad-hoc summertime fixes (natlawreview.com).
The Occupational Safety and Health Administration rewrote its heat enforcement program on April 10, sharpening inspections for workplaces where indoor and outdoor heat is most likely to injure workers. (osha.gov) The revised National Emphasis Program took effect immediately on April 10, 2026, and replaces the version OSHA first issued on April 8, 2022. OSHA said it used agency and Bureau of Labor Statistics data from 2022 through 2025 to reset inspection priorities. (osha.gov) OSHA said the new list covers 55 high-risk industries in general industry, construction, maritime, and agriculture. Inspectors can expand any inspection when they see heat hazards on “heat priority days,” and they can run random heat inspections in high-risk industries when the National Weather Service issues a heat advisory or warning. (osha.gov) A National Emphasis Program is OSHA’s way of concentrating inspectors on hazards or industries it considers especially dangerous. OSHA says these programs are temporary, data-driven enforcement campaigns built from inspection records, injury and illness data, National Institute for Occupational Safety and Health reports, and related research. (osha.gov) Heat is on that list because the risk is both widespread and preventable. OSHA says millions of U.S. workers are exposed to job-related heat, thousands get sick each year, and some cases are fatal. (osha.gov) The agency’s heat page says dangerous exposure is not limited to outdoor summer jobs. OSHA lists indoor settings such as bakeries, kitchens, laundries, boiler rooms, iron and steel mills, foundries, manufacturing with furnaces, and warehouses alongside outdoor work in agriculture, construction, landscaping, roofing, oil and gas, and package delivery. (osha.gov) The rewrite also changes how the program is administered. OSHA said it removed outdated background material, dropped the old numerical inspection goal, and added reorganized appendices for evaluating an employer’s heat program and for citation guidance. (osha.gov) That leaves employers with a more explicit checklist for prevention instead of seasonal improvisation. The directive says the program is intended to encourage early interventions during high-heat conditions and applies OSHA-wide, while adoption by state-plan states is encouraged rather than automatic. (osha.gov) The enforcement update is moving alongside a broader federal rulemaking that is still unfinished. OSHA’s proposed heat standard was published on August 30, 2024, public hearings ran from June 16 to July 2, 2025, and the post-hearing comment period closed on October 30, 2025. (osha.gov) For now, the practical change is immediate: OSHA’s heat program is in force now and is set to remain in place for five years after April 10, 2026, with inspections and outreach aimed more narrowly at the workplaces the agency says show the highest heat risk.
