The heat is on—and this time, it’s official. Starting April 29, 2025, Nevada OSHA is implementing new heat illness prevention regulations across the state for both indoor and outdoor workplaces.
If you’re an EHS manager overseeing a construction site, public works, or a manufacturing facility, these new heat illness standards will affect how you operate changes matter—and how you protect your teams.
Here’s a breakdown of what you need to know about the new Nevada OSHA heat rules, what’s changing, and how Perry Weather can help you stay compliant with ease.
What are the new Nevada OSHA Heat Illness Prevention Recommendations?
Key Requirements for Employers
For construction teams, outdoor laborers, and indoor crews without full climate control, heat exposure can be dangerous or even deadly if not properly managed.
If your workers face heat risks outdoors or indoors without consistent cooling, here’s what you now must do:
1. Conduct a Heat-Specific Job Hazard Analysis (JHA)
Every employer must identify when and where employees are at risk of heat illness. The following conditions that can cause heat stress must be documented:
✅ Environmental risks (temperature, humidity)
✅ Physical job demands (heavy lifting, PPE use, direct sun exposure)
✅ Consider risk levels based on WBGT (Wet Bulb Globe Temperature) and other heat factors.
2. Develop and Implement a Heat Illness Prevention Plan (HIIP)
Make sure to update your written safety program to also include a dedicated section detailing your heat illness prevention plan. It needs to cover:
- Hydration access and schedules: Access to clean, drinking potable water
- Work/rest cycles on high-heat days: Provision of rest breaks for employees exhibiting heat illness symptoms
- Provision of shade and cool-down areas and cooling stations
- Identifying any work processes that generate additional heat or humidity
- Real-time temperature and WBGT monitoring
- Recognizing and responding to heat illness symptoms
- Emergency medical response procedures: Employers must designate an employee to carry out emergency response functions based on the job hazard analysis, in case an employee is exposed to heat illness.
3. Train Employees
Initial training must be completed before exposure begins and should be refreshed regularly, especially before the summer season.
Employers must provide training to all employees (and documentation of that training) on:
– Recognizing early signs of heat illness
– Preventing heat stress through hydration and rest
– How acclimatization works for new and returning workers
– Emergency response procedures
4. Monitor Heat Stress and Environmental Conditions Actively
Employers must actively track on-site temperatures and conditions daily—not just trust weather apps. Using real-time Wet bulb globe temperature (WBGT) monitoring is strongly recommended for accuracy.
– Adjust work schedules based on thresholds
– Enforce mandatory breaks and hydration when conditions warrant
– Trigger emergency response if heat stress symptoms arise
Important: Climate-controlled indoor worksites are exempt from the new job hazard analysis (JHA), heat illness prevention plan, and training requirements—but outdoor worksites and indoor spaces without consistent air conditioning are not.
What Happens If You Don’t Comply with the Nevada OSHA heat rules?
Failure to meet these new standards could result in:
– OSHA citations and fines
– Potential lawsuits from affected employees
– Increased insurance costs
– Lost productivity from preventable illnesses
And most importantly, it increases the risk of serious harm to your workers.

Nevada OSHA Heat Stress FAQs
Who do these new Nevada OSHA heat rules apply to?
A: These heat illness rules apply to any and all Nevada employers with 10 or more employees if their employees work in outdoor heat or in indoor locations without air conditioning or other climate control.
Who must create a Heat Illness Prevention Plan?
A: The regulation applies to both indoor and outdoor settings. These heat illness prevention requirements apply to all Nevada employers with 10 or more employees.
What must my heat illness prevention plan (HIIP) include?
A: Every heat illness prevention plan must include policies on hydration, shade, rest, monitoring temperature, recognizing symptoms, and responding to emergencies.
Do I need to monitor WBGT, temperature, or both?
A: Temperature and environmental factors like humidity must be monitored, but using WBGT offers a more complete and compliant measurement.
Will employees be allowed more breaks when it’s hot?
A: Yes. The new law requires employers to provide more frequent hydration and rest breaks during high-heat conditions.
