Keep your employees cool (or at least try).
OSHA has issued a revised National Emphasis Program (NEP) targeting heat-related hazards in both indoor and outdoor workplaces across general industry and construction. While the program replaces the 2022 version, employer expectations remain largely the same.
OSHA continues to expect employers to implement practical heat illness prevention measures, including:
• Training employees to recognize symptoms of heat illness and understand risk factors such as medications and medical conditions
• Providing appropriate PPE, such as hats, reflective or loose-fitting clothing, and cooling gear where appropriate
• Using engineering controls like air conditioning, fans, and shade
• Applying administrative controls such as scheduling hot work during cooler hours, ensuring access to cool drinking water and rest breaks, and allowing time for acclimatization
Although OSHA describes these steps as voluntary, employers have historically received citations under the General Duty Clause for failing to address heat hazards.
The NEP authorizes both programmed inspections in targeted industries (including warehousing, bakeries, foundries, sawmills, and waste collection) and unprogrammed inspections based on complaints, referrals, or hazards observed during other inspections. OSHA may also initiate inspections during National Weather Service heat advisories, which can occur when the heat index reaches 80°F or higher.
During inspections, compliance officers will evaluate whether employers are acting in good faith to provide water, rest, shade, training, and acclimatization practices. Because OSHA does not provide a precise compliance formula, employers should maintain a written heat illness prevention policy and be prepared to demonstrate consistent implementation.
States with their own OSHA plans are encouraged to adopt comparable enforcement approaches.
