The Safety Standard

Every year, thousands of workers suffer from overexposure to the sun while performing their jobs outdoors. While most people think of sunburn as a mild inconvenience, repeated exposure without protection can lead to long-term health issues including skin cancer, heat exhaustion, and vision damage. This blog aims to provide employers, supervisors, and workers with practical and regulatory-aligned guidance to mitigate sun-related risks—especially in industries like construction, transportation, landscaping, and agriculture.

Whether you're overseeing crews on highways, farms, or loading docks, sun protection is not just about comfort—it’s about compliance, productivity, and worker safety. This article explores the science behind UV risks, outlines key protective measures, and shares OSHA-recommended strategies to help you build a more resilient and informed workforce.

Why Sun Protection Matters in the Workplace

The Risks of UV Exposure

Ultraviolet (UV) radiation from sunlight is classified as a Group 1 carcinogen by the World Health Organization (WHO) [source]. Prolonged or repeated exposure increases the risk of:

• Skin cancer, including melanoma, basal cell carcinoma, and squamous cell carcinoma

• Sunburn, which can damage the skin even on cloudy days

• Heat exhaustion and heat stroke, which can escalate quickly in outdoor labor settings

• Eye damage, such as cataracts and photokeratitis (“sunburned eyes”)

For employers, the implications go beyond health. Sun-related illnesses can lead to increased absenteeism, workers’ compensation claims, and OSHA violations.

High-Risk Industries

While all outdoor workers are at risk, the most vulnerable sectors include:

• Construction and roofing

• Transportation and delivery

• Oil, gas, and utility work

• Landscaping and groundskeeping

• Agriculture and farming

Even truck drivers and intermodal workers, who may not consider themselves “outdoor workers,” can be exposed during loading/unloading or long drives with high sun glare.

What OSHA Says About Sun Protection

While OSHA does not have a specific regulation solely for UV protection, employers are required under the General Duty Clause, Section 5(a)(1) of the OSH Act, to provide a workplace “free from recognized hazards.” This includes preventing heat-related illnesses and providing PPE where necessary.

Refer to OSHA’s full Heat Illness Prevention Campaign for more information, especially the three key pillars:

• Water. Rest. Shade.

• Acclimatization

• Training and emergency response planning

Additionally, DOT-regulated workers, including drivers under FMCSA, should be made aware of rest requirements and sun protection strategies during inspections, delays, and wait times in hot environments.

Signs of Sun-Related Illnesses to Watch For

Training your team to recognize symptoms can be lifesaving. Early signs of heat exhaustion or sun stroke include:

• Heavy sweating

• Nausea or vomiting

• Dizziness or confusion

• Hot, dry skin (a sign heat stroke may be occurring)

• Muscle cramps

• Rapid pulse

OSHA’s First Aid topic page offers employer guidance on how to respond in real-time to these issues. Having protocols and designated responders trained in heat emergency first aid is crucial.

Best Practices for Protecting Outdoor Workers

Implementing a sun safety program doesn't have to be costly or complicated. Here's a breakdown of the most effective controls:

1. Schedule Smart

• Avoid strenuous outdoor tasks during peak UV hours: 10 a.m. to 4 p.m.

• Rotate job functions or assign indoor duties mid-day

• Use NOAA’s UV Index Forecast Tool for planning

2. Provide Personal Protective Equipment (PPE)

• Wide-brimmed hats or neck flaps

• ANSI-rated UV-blocking safety glasses

• Lightweight, long-sleeved shirts (ideally UPF-rated)

• Cooling vests or bandanas for temperature regulation

Explore NIOSH’s recommendations for PPE and sun-protective clothing on their Sun Safety for Workers resource page.

3. Apply Sunscreen — and Reapply

• Broad-spectrum SPF 30+ sunscreen

• Water- and sweat-resistant formulations

• Reapply every 2 hours, or more frequently if sweating

Employers should provide sunscreen on job sites and encourage its use. It can be dispensed in single-use packs or bulk pumps for hygienic distribution.

4. Create Shade Zones

• Pop-up tents, trailers, or permanent structures

• Vehicles with A/C as designated rest stations

• Encourage 15-minute shade breaks every 2 hours when UV index is high

5. Train and Communicate

• Train supervisors and crews on early warning signs

• Encourage a buddy system

• Post heat safety signage in high-traffic or remote areas

For additional educational material, the California Department of Industrial Relations offers downloadable heat illness prevention resources here that can be adapted to other regions.

Myths About Sun Exposure at Work

Myth: You only need protection when it’s sunny.
Reality: Up to 80% of UV rays penetrate clouds. Workers need sun protection even on overcast days.

Myth: Dark skin doesn’t get sunburned.
Reality: While darker skin may offer more natural protection, it’s still vulnerable to UV damage and skin cancer.

Myth: A tan protects you.
Reality: A tan is a sign of skin damage and does not offer reliable protection.

Integrating Sun Safety Into Your Safety Program

To improve adoption, integrate sun protection into your existing workplace safety or injury prevention programs. This can be done by:

• Including it in toolbox talks

• Making sun safety a required training topic in onboarding

• Logging sunscreen, shade structures, and PPE in your job safety analysis (JSA)

• Tracking related incidents in your OSHA 300 logs

You can also benchmark your sun safety program using CDC’s Workplace Health Model.

Sun Safety Is a Year-Round Responsibility

Even in cooler months or northern climates, workers face sun exposure risks. UV rays reflect off snow, water, and pavement, often intensifying exposure. Employers should communicate that sun protection is not seasonal and continue protocols throughout the year.

Resources for Employers and Safety Managers

Here are several trusted sources to support your program:

• OSHA – Heat Illness Prevention
  

• CDC – Skin Cancer Prevention

• NIOSH – UV Safety for Workers

• EPA UV Index Tool

Introduction

As temperatures rise each summer, so does the risk of heat-related illnesses on job sites across the country. From construction zones to delivery routes, manufacturing floors to agricultural fields, millions of U.S. workers are exposed to high-heat environments—putting them at risk for heat exhaustion, heat stroke, and other preventable health hazards.

Whether you’re an EHS manager, site supervisor, or operations lead, understanding how to prevent and respond to heat illness is more than a matter of compliance—it’s a matter of protecting your people and keeping your workplace running smoothly.

What Is Heat Illness?

Heat illness is a spectrum of health conditions that occur when the body can’t cool itself effectively. It ranges from mild symptoms like heat rash and cramps to severe and life-threatening conditions such as heat exhaustion and heat stroke.

According to the Occupational Safety and Health Administration (OSHA), thousands of workers fall ill from heat exposure each year—and dozens die. These incidents are largely preventable with the right preparation and response.

Common Types of Heat Illnesses

1. Heat Rash
Often the first warning sign, heat rash appears as red clusters of small blisters, typically in areas where sweat accumulates. While not life-threatening, it’s uncomfortable and may hinder performance.

2. Heat Cramps
Painful muscle spasms, often in the legs or abdomen, are caused by loss of salt through sweating. Cramps may be a precursor to more serious conditions.

3. Heat Exhaustion
Symptoms include dizziness, nausea, heavy sweating, weakness, and rapid heartbeat. Left untreated, heat exhaustion can progress to heat stroke.

4. Heat Stroke (Medical Emergency)
The most severe form of heat illness, heat stroke occurs when the body’s core temperature exceeds 104°F. Symptoms include confusion, loss of consciousness, dry skin, and seizures. This is a medical emergency—911 should be called immediately.

Who’s Most at Risk?

Workers in industries with high heat exposure are particularly vulnerable. These include:

• Construction

• Agriculture

• Transportation and warehousing

• Manufacturing

• Oil and gas

• Landscaping

• Waste management

Certain groups also face elevated risk: new workers, older adults, people with chronic health conditions, and those who wear heavy PPE.

The Centers for Disease Control and Prevention (CDC) notes that acclimatization—or gradually increasing exposure to heat—is a critical step in prevention, especially for new or returning workers.

Key Components of a Heat Illness Prevention Plan

1. Access to Water, Rest, and Shade
Encourage frequent water breaks, even when workers aren’t thirsty. OSHA recommends one cup (8 oz.) of water every 15–20 minutes. Rotate workers through shaded or air-conditioned areas, and increase break frequency during high-heat conditions.

2. Heat Acclimatization Programs
Implement phased work schedules for new employees or those returning after extended absences. A gradual increase in workload over 7–14 days helps the body adapt.

3. Training and Awareness
Supervisors and workers should be trained to recognize early symptoms and know how to respond. OSHA’s Heat Illness Prevention Training Guide offers free resources and multilingual materials.

4. Monitoring Environmental Conditions
Use Wet Bulb Globe Temperature (WBGT) monitors or consult local weather forecasts. High humidity can drastically increase heat risk, even when the air temperature is moderate.

5. Emergency Response Protocols
Clear, practiced protocols are vital. Make sure your team knows:

• How to identify symptoms

• When to move a worker to a cooler location

• When to call 911

• How to perform first aid (e.g., applying cool compresses, removing outer clothing)

Best Practices by Industry

Construction & Roofing
Rotate tasks to avoid long exposure, ensure PPE doesn’t trap heat unnecessarily, and use cooling vests when possible.

Warehousing & Logistics
Install fans or HVAC systems where feasible, limit time in trailers or poorly ventilated spaces, and schedule physically demanding tasks during cooler hours.

Transportation & Trucking
Drivers face added risk due to cab conditions and loading/unloading in the sun. FMCSA emphasizes driver wellness and hydration.

Agriculture & Landscaping
Use portable shade structures, provide electrolyte-replenishing beverages, and encourage team leads to monitor each other for symptoms.

Regulatory Considerations

OSHA Guidance
While there is no federal OSHA standard specific to heat, the General Duty Clause requires employers to provide a workplace free from recognized hazards—including heat stress. Several states, such as California and Washington, have their own heat illness prevention standards.

• California Heat Illness Prevention Standard (Title 8, Section 3395)

• Washington State Heat Rules 

DOT/FMCSA Guidelines
While the FMCSA doesn’t have heat-specific regulations, it does require motor carriers to protect drivers’ health and prevent unsafe operating conditions, which may be exacerbated by high heat.

Leveraging Technology

Consider using digital tools to:

• Push heat advisories to teams based on location

• Track worker acclimatization

• Automate break reminders

• Monitor conditions with smart sensors

These approaches not only improve compliance but help organizations respond proactively to changing weather conditions.

Final Thoughts

Heat illness is one of the most preventable workplace health threats—yet it's one of the most persistent. By integrating awareness, planning, and responsive action, employers can reduce risks, avoid downtime, and support a safer, more resilient workforce.
