As temperatures rise across the country, heat illness becomes a serious concern for workers in various industries, especially those on job sites like construction, landscaping, or manufacturing. At GotSafety, we’re committed to helping businesses and workers stay safe, no matter where you are in the U.S. Whether you’re in the scorching deserts of Arizona, the humid summers of Florida, or the unpredictable heatwaves of the Midwest, heat illness prevention is a universal priority. In this blog, we’ll break down what heat illness is, how to recognize it, and actionable steps to keep your team safe on the job.
Understanding Heat Illness: A Nationwide Concern
Heat illness occurs when the body cannot cool itself effectively, leading to a range of conditions from mild heat stress to life-threatening heat stroke. According to the Occupational Safety and Health Administration (OSHA), thousands of workers suffer from heat-related illnesses each year, with some cases resulting in fatalities. While the risk may vary depending on local climate—such as the dry heat of Nevada versus the humid conditions in Georgia—the danger is real in every state.
Common types of heat illness include:
- Heat Stress: Symptoms include excessive sweating, fatigue, and muscle cramps.
- Heat Exhaustion: Signs include heavy sweating, dizziness, nausea, and a weak pulse.
- Heat Stroke: A medical emergency characterized by a body temperature above 104°F, confusion, and loss of consciousness.
Workers on job sites are particularly vulnerable due to prolonged exposure to the elements, physical exertion, and sometimes inadequate access to shade or hydration. That’s why proactive prevention is key.
Recognizing the Risk Factors
Heat illness doesn’t discriminate by state, but certain factors can increase the risk for workers:
- High Temperatures and Humidity: Even states with milder summers, like Washington or Maine, can experience heatwaves that catch workers off guard.
- Physical Activity: Jobs requiring heavy lifting, such as construction or warehousing, increase the body’s heat production.
- Clothing and PPE: Protective gear, while essential for safety, can trap heat and prevent cooling.
- Acclimatization: Workers new to hot environments—or those returning after time off—need time to build tolerance to higher temperatures.
Actionable Steps to Prevent Heat Illness
Here are practical, state-agnostic strategies to protect your team from heat illness, whether you’re on a job site in Texas or a warehouse in Michigan:
- Ensure workers have easy access to cool, clean drinking water at all times. OSHA recommends drinking about 1 cup of water every 15-20 minutes during hot conditions.
- Encourage workers to hydrate before, during, and after their shifts. In humid states like Louisiana, where sweat doesn’t evaporate easily, this is especially critical.
- Set up shaded areas or cooling stations on job sites. Portable canopies or tents work well in open areas, such as construction sites in rural Nebraska or urban California.
- Schedule frequent rest breaks, especially during the hottest parts of the day (typically 10 a.m. to 4 p.m.). In states like Colorado, where elevation can amplify heat effects, more frequent breaks may be necessary.
- Train your team to recognize the signs of heat illness using resources like GotSafety’s video series (e.g., “Heat Illness Prevention: Acclimatization” – Episode 18).
- Teach workers to act quickly if they or a coworker show symptoms. For example, in a heat stroke emergency, call 911 immediately, move the person to a cooler area, and apply cool water to their skin.
- Gradually increase workers’ exposure to heat over 7-14 days. This is crucial for new hires or workers returning after a break, whether they’re in the humid Southeast or the dry Southwest.
- Start with shorter shifts in the heat, increasing exposure as their bodies adapt. For example, a worker in Oregon might need less acclimatization than one in Arizona, but the process is still essential.
- Shift heavy tasks to cooler parts of the day, such as early morning or late evening. This works well in states like Illinois, where summer days can be hot but mornings are cooler.
- Rotate workers between high-heat and low-heat tasks to reduce overall exposure.
- Encourage lightweight, loose-fitting clothing where possible, while ensuring it meets safety standards. In states like Florida, where humidity is high, breathable fabrics are a must.
- Supply cooling vests, bandanas, or hats for workers in direct sunlight, such as those on a job site in Nevada.
- Use tools like the OSHA-NIOSH Heat Safety Tool app to check the heat index in your area. The heat index combines temperature and humidity to show how hot it feels, which is critical in states like Alabama or South Carolina.
- Adjust work plans if the heat index exceeds 91°F, as this is when the risk of heat illness rises significantly.
Creating a Heat Illness Prevention Plan
Every workplace should have a written heat illness prevention plan that’s accessible to all employees. Here’s a simple framework that works across all 50 states:
- Designate a Heat Safety Coordinator: Assign someone to monitor conditions and ensure compliance with safety protocols.
- Emergency Procedures: Outline steps for responding to heat illness, including who to call and where to find first aid supplies.
- Training: Regularly train workers on heat illness prevention, using engaging resources like GotSafety’s cartoon-style videos to make the content memorable.
- Documentation: Keep records of training sessions, heat-related incidents, and preventive measures taken.
Why Heat Safety Matters for Your Business
Beyond the moral imperative to protect your team, heat illness prevention has tangible benefits for your business:
- Reduced Downtime: Healthy workers are productive workers. Preventing heat illness keeps your projects on schedule, whether you’re building in New York or landscaping in Texas.
- Lower Costs: Heat-related incidents can lead to medical expenses, workers’ compensation claims, and OSHA fines. Proactive prevention saves money.
- Compliance: While OSHA doesn’t have a specific heat standard (as of April 2025), many states—like California, Washington, and Oregon—have their own heat illness regulations. Following best practices ensures you’re prepared for any future federal or state requirements.
