As temperatures continue to rise and extreme heat events become more common, the Occupational Safety and Health Administration (OSHA) has extended its National Emphasis Program (NEP) on Outdoor and Indoor Heat-Related Hazards through April 8, 2026. Originally set to expire in 2025, this extension signals OSHA’s ongoing commitment to protecting workers from heat-related illnesses and injuries, which remain a serious threat in many workplaces across the United States.
What Is the NEP?
The NEP, originally launched in April 2022 under Directive CPL 03-00-024, focuses on industries with the highest risk of heat exposure—such as agriculture, construction, manufacturing, warehousing, and transportation. It enables OSHA to conduct proactive inspections, even in the absence of a formal complaint, when the National Weather Service issues a heat advisory or warning. This is especially important for workers who are exposed to high temperatures in both outdoor and indoor environments, such as those working near heat-generating equipment.
What Employers Must Do
Under the NEP, employers in high-risk industries are expected to:
-
Implement heat illness prevention programs, which include providing access to water, rest, and shade or cooling areas.
-
Train employees and supervisors on the signs, symptoms, and prevention of heat-related illnesses.
-
Monitor ambient temperatures and modify work schedules or conditions during high-heat days.
-
Provide acclimatization protocols for new or returning workers to gradually adjust to working in heat.
-
Develop emergency response procedures for heat-related illnesses.
While OSHA has not yet finalized a permanent heat standard, employers should be aware that failure to take appropriate steps under the General Duty Clause of the Occupational Safety and Health Act may still result in citations.
What Employees Need to Know
Employees also play an important role in preventing heat-related incidents. Workers should:
-
Stay hydrated by drinking water frequently, even if they aren’t thirsty.
-
Take scheduled breaks in shaded or cooled areas, especially during peak heat hours.
-
Report symptoms early, such as dizziness, nausea, headache, or excessive sweating.
-
Look out for coworkers, as heat illness can progress quickly and may be difficult to recognize in oneself.
-
Participate in training and follow safety procedures provided by the employer.
Final Thoughts
The extension of OSHA’s NEP through 2026 gives both employers and employees more time to adapt, educate, and strengthen protections against heat-related hazards. As the climate continues to warm, workplace heat safety will remain a top priority. Employers should take this opportunity to reassess their heat illness prevention strategies and ensure compliance, while workers should stay informed and vigilant about their own well-being.
