For workers across the Southwest, exposure to ultraviolet (UV) rays is a daily reality. Construction crews, landscapers, agricultural workers, utility employees, delivery drivers, and others who spend time outdoors face an increased risk of skin cancer, eye damage, and premature aging from prolonged sun exposure.
“Heat illness often gets the most attention during the summer, but employers shouldn’t overlook another serious workplace hazard: exposure to UV radiation,” says Rick Murray, President and CEO of Arizona Chapter National Safety Council. “For workers who spend time outdoors, prolonged UV exposure can increase the risk of skin cancer, eye damage, and other long-term health issues. By taking steps to reduce it, organizations help protect their workforce while supporting operational efficiency”
The risk is amplified in the Southwest, where some of the highest UV index levels in the country combine with long hours spent outdoors and exposure to reflective surfaces such as concrete, asphalt, and metal.
The Hidden Dangers of UV Exposure
UV rays are invisible, but their effects can be lasting.
According to the Centers for Disease Control and Prevention (CDC), exposure to UV radiation increases the risk of all major forms of skin cancer. It can also cause eye damage, including cataracts and other conditions that may impair vision over time.
Many people associate sunburn with hot weather, but UV exposure remains a risk even on cooler or cloudy days. Damage from UV radiation accumulates over time, meaning employees may not notice the effects until years later.
Sun Exposure Has Business Consequences
According to the CDC, employers may be required to provide workers’ compensation benefits to employees who develop skin cancer as a result of occupational sun exposure.
Skin cancer can also affect workforce performance. The CDC estimates that Americans lose more than $100 million in productivity each year because of restricted activity or missed work associated with skin cancer.
For employers, the costs of inadequate sun protection can include increased absenteeism, workers’ compensation claims, lost productivity, and additional healthcare expenses.
Eye Protection Matters
In 2025, Personal Protective Equipment (PPE) for Eye and Face Protection ranked among OSHA’s Top 10 most frequently cited standards.
Without adequate protection, UV rays can damage the eyes and surrounding tissue. Long-term exposure can contribute to cataracts, retinal damage, and other serious vision problems.
Employers should ensure workers have access to appropriate UV-rated safety glasses, goggles, or face protection that meets applicable safety requirements while also shielding them from harmful UV rays.
Building a Workplace Sun Safety Program
An effective sun safety program doesn’t have to be complicated. But it does require consistency. Employers should consider the following steps:
Employer Sun Safety Checklist
• Provide broad-spectrum sunscreen with SPF 30 or higher at work sites.
• Encourage employees to reapply sunscreen throughout the day, especially after sweating.
• Require or encourage lightweight, long-sleeved clothing that covers exposed skin.
• Provide wide-brim hard hat attachments, neck shades, or other protective gear where appropriate.
• Supply UV-rated safety glasses or protective eyewear.
• Schedule outdoor work to reduce exposure during peak UV hours when possible.
• Provide access to shaded rest areas and covered break locations.
• Train employees on the risks of UV exposure and the signs of sun-related health issues.
• Include sun safety in regular safety meetings and seasonal training programs.
• Lead by example. Supervisors who practice sun safety reinforce its importance to their teams.
Protect Workers Year-Round
In the Southwest, where intense UV exposure is a year-round reality, sun safety deserves the same level of attention as other workplace hazards. A proactive approach today can help prevent serious health consequences tomorrow.
