Occupational Sun Safety: Protecting Your Workforce in Hot Conditions
Why Sun Safety Matters on the Job
Working outdoors brings numerous challenges, and sun exposure is one of the most dangerous yet often overlooked. As heatwaves become more frequent and severe, so does the risk of heat-related illnesses. According to the U.S. Bureau of Labor Statistics, 48 workers died from exposure to environmental heat in 2024, with approximately 7,100 nonfatal cases resulting in lost work time in 2023–2024. Proactive sun safety is not just a best practice. It is a necessity.
Heat-Related Illnesses Are on the Rise
The Occupational Safety and Health Administration (OSHA) reports that the three-year average of workplace deaths caused by heat has doubled since the early 1990s. This alarming trend highlights the increasing risks associated with heat exposure in occupational settings, emphasizing the need for proactive sun safety measures.
OSHA Is Increasing Heat Enforcement in 2026
In April 2026, OSHA renewed its National Emphasis Program on heat-related hazards, extending enforcement through 2031. Heat inspections have grown from roughly 200 per year to approximately 2,400 per year, now accounting for about 6% of all OSHA inspections. Compliance officers are directed to expand inspections during heat advisories and when the heat index reaches 80°F, particularly across 55 high-risk industries.
Employers do not need a finalized federal heat standard to face scrutiny. A documented heat safety program, consistent training records and clear response protocols are the best defense against a citation and, more importantly, the best protection for workers.
Key Strategies for Onsite Sun Safety
Hydration & Nutrition
Avoid caffeine and alcohol during hot days.
Encourage frequent water breaks—every 15 to 20 minutes.
Provide electrolyte beverages when possible.
Shade and Scheduling
- Schedule strenuous tasks during early mornings or evenings.
- Rotate workers to reduce prolonged exposure.
- Create shaded break areas with cooling stations.
Protective Gear and Clothing
- Encourage tight-weave or high-SPF clothing and long sleeves and pants when appropriate.
- Require lightweight, light-colored, breathable clothing.
- Provide wide-brimmed hats, neck shades and UV-blocking sunglasses.
- Require broad-spectrum SPF 30 or higher sunscreen, reapplied every two hours or more often when sweating.
Heat Acclimatization
- Gradually increase workloads for new or returning employees.
- Closely monitor high-risk workers.

Educating and Training Your Crew to Ensure Occupational Sun Safety
Educating your workers about the potential dangers they face and training them how to respond is key to preventing occupational sun injuries.
Before the weather gets too warm, hold a team meeting to go over some of the greater dangers of working outdoors in the summer. Include this information in your employee manual and send it out via email at least once a year. Discuss the resources available at the worksite, such as adjusted schedules, shade and hydration stations, but be sure to cover things your workers need to do on their own.
Certain medications, including antibiotics, acne medicine, diabetes medications and cholesterol-lowering drugs, can increase a worker’s sun sensitivity. Encourage workers to speak with their doctors or your onsite clinic staff if they are concerned about how their medication may impact them.
Discuss the UV index and all sun-related PPE, providing a list of nearby or online places where workers can purchase their own garments. Remind workers that you will have sunscreen and other items available for refills or if they forget something.
Engage your onsite occupational healthcare team to educate your workers on the signs and symptoms of heat illnesses and sun overexposure. They can help your workers know what to look for in themselves and others and provide resources on where to get help in case of an incident.

Frequently Asked Questions
What are the early signs of heat-related illness?
Look for heavy sweating, dizziness, weakness, headache, nausea and muscle cramps. More serious symptoms include confusion, vomiting and loss of consciousness.
How much water should workers drink?
A general rule is 1 cup every 15–20 minutes during strenuous outdoor work. Electrolyte drinks can help replenish lost minerals.
What kind of sunscreen should employees use?
Broad-spectrum SPF 30 or higher. Reapply every 2 hours or more frequently if sweating.
Can heat illness happen even on cloudy days?
Yes. UV exposure and high humidity still pose risks even when the sun isn’t visible.
What should employers do during a heat advisory?
Modify work schedules, implement additional hydration and rest protocols and closely monitor high-risk employees.
