OSHA Issues Heat Injury and Illness NPRM

Exhausted warehouse worker

On August 30, 2024, OSHA’s proposed rule on heat injury and illness prevention in outdoor and indoor settings was published in the Federal Register, officially starting the comment period.

OSHA’s proposed a rule would require employers to develop programs to protect their employees from heat hazards in both the outdoor and indoor work environments.

The proposed rule…

  • Would apply broadly to all employers conducting outdoor and indoor work activities in general industry, construction, maritime and agriculture (where OSHA has jurisdiction).
  • Is a programmatic standard that would require employers to evaluate their workplaces and implement controls to mitigate employee exposures though engineering and administrative controls, training, effective communication and other measures.
  • Includes initial and high heat triggers at the 80- and 90-degree levels, which would require increasingly stringent control measures to protect employees.
  • Includes certain exemptions, including short-duration exposures, emergency response activities, and workplaces that are kept below 80 degrees.

The proposed rule also was the subject of a Small Business Advocacy Review panel in 2023 (see the Heat Injury and Illness SBREFA | Occupational Safety and Health Administration (osha.gov)).


Comments on OSHA’s proposed Heat Injury and Illness Prevention rule are due by December 30, 2024.
