Summary At a Glance
- OSHA has extended its National Emphasis Program targeting heat-related hazards, allowing continued inspections in high-risk industries on “heat priority days” (80°F+ heat index).
- The program is currently active, with a focus on acclimatization, training, and prevention measures.
- Employers should expect increased scrutiny during warmer months, particularly for new or returning workers.
As warmer weather arrives, it is the perfect time for employers to refresh their safety protocols. On April 10, 2026, the Occupational Safety and Health Administration (OSHA) announced the extension of its National Emphasis Program (NEP) focused on protecting workers from heat-related hazards. This directive allows OSHA to continue prioritizing inspections and outreach in 55 high-risk industries, including construction, manufacturing, and warehousing. Under this program, compliance officers conduct inspections on “heat priority days,” which occur whenever the local heat index reaches 80°F or higher. The program also maintains a heavy emphasis on heat acclimatization, as many serious incidents occur during a worker’s first few days in a hot environment.
To ensure your organization stays compliant while the temperatures rise, start by reviewing your heat illness prevention program to ensure it includes specific protocols for hydration, rest breaks, and shade. It is also vital to implement acclimatization procedures that gradually increase workloads for new or returning employees so their bodies can safely adjust to the heat.
Additionally, you should designate a team member to track the National Weather Service heat index daily to identify “heat priority days” and trigger necessary safety measures. Finally, conduct training sessions to help staff recognize the early signs of heat exhaustion and understand your organization’s specific emergency response procedures. Consistent monitoring and education are the most effective ways to prevent heat-related incidents as the season changes.
