Why Heat Exposure on the Job Is a Growing Concern
Each year, thousands of U.S. workers suffer from heat-related illnesses—and many of these cases occur right here in North Carolina. The state’s combination of heat and humidity during summer months makes job sites especially dangerous for those without proper protections.
According to the U.S. Department of Labor, heat illness can lead to hospitalization and even death. Yet many workers don’t realize they have rights when it comes to unsafe working temperatures.
On April 24, 2024, the U.S. Department of Labor took a major step toward protecting workers from the dangers of heat exposure by presenting the initial regulatory framework for a new heat safety rule. The Advisory Committee on Construction Safety and Health unanimously approved moving forward with the proposed rule, which will address both indoor and outdoor workplace heat risks. While the formal rulemaking process continues, OSHA is ramping up enforcement under its existing authority—especially through its National Emphasis Program targeting heat-related hazards. Since 2022, nearly 5,000 heat-related inspections have been carried out across high-risk industries.
The agency is placing particular focus on vulnerable groups, including agricultural workers on H-2A visas, who often lack control over their work environments and face language barriers. OSHA is urging employers to take proactive steps—like offering water, breaks, and shaded rest areas—to prevent serious and often fatal heat illnesses. The department emphasized that no worker should suffer or die due to employer negligence when basic safety measures could have prevented harm. Source: U.S. Department of Labor.
Are There Laws That Set a Maximum Temperature for Working?
There’s no specific federal law that sets an exact temperature at which work must stop. However, under the OSHA General Duty Clause, employers are legally required to provide a safe workplace—this includes protecting workers from known heat hazards.
In North Carolina, workplace safety is governed by the North Carolina Department of Labor, which enforces OSHA standards and investigates workplace complaints.
How Hot Is Too Hot to Work?
OSHA uses the Heat Index—a combination of air temperature and humidity—to determine when conditions become hazardous. Here’s a general breakdown:
- 80°–89°F: Caution for prolonged activity or direct sun
- 90°–103°F: Increased risk, frequent water/rest breaks required
- 104°–115°F: High risk – job modifications or rescheduling may be needed
- 116°F and up: Very high to extreme risk – exposure should be limited or avoided entirely
If you’re exposed to these conditions without proper safety measures, you may have a legal claim.
Employer Responsibilities During Extreme Heat
Employers in North Carolina are expected to take proactive steps to reduce heat-related risks. These steps include:
- Providing access to cool drinking water
- Allowing regular rest breaks in shaded or cooled areas
- Training employees on the signs of heat exhaustion and heat stroke
- Modifying work schedules to avoid peak heat hours
- Using acclimatization protocols for new or returning workers
If these steps are not being followed, and workers fall ill, the employer may be liable for any resulting injuries or illnesses.
Indoor Workplaces Are Not Exempt
Warehouses, kitchens, factories, and laundromats can also reach extreme temperatures—especially if they lack proper ventilation or air conditioning. Employees in these settings are equally protected under OSHA regulations.
Can You Legally Refuse to Work in Extreme Heat?
Under certain conditions, yes. If you believe you are in imminent danger due to excessive heat and your employer refuses to act, OSHA permits you to refuse unsafe work. You must:
- Notify your supervisor about the dangerous condition
- Give your employer a chance to correct the issue
- Remain at the worksite unless told to leave
- File a formal complaint with OSHA as soon as possible
It’s always wise to document your concerns and notify HR or management in writing.
