Heat stress is one of the leading causes of weather-related workplace deaths in the U.S., and for construction and tower crews, the risk is even greater. Long hours in direct sunlight, physical exertion, and limited access to shade create dangerous conditions for heat-related illness.
As warmer weather approaches, it’s important to understand the risks and take proactive steps to keep crews safe and compliant.
Understanding heat-related hazards and OSHA heat safety expectations isn’t optional — it’s essential for protecting your team on the job.
Key Heat Stress Facts for Outdoor Workers
Heat-related illness can happen faster than people think, especially during the summer months. Here are a few important things to keep in mind:
• Heat-related illnesses can escalate quickly, from heat exhaustion to heat stroke
• Humidity makes it harder for your body to cool itself naturally
• Direct sunlight can raise the heat index by 10–15°F
• New and returning workers are at higher risk during their first several days on the job
• You can become dehydrated before you even feel thirsty
For employers, this is why following OSHA heat stress guidelines and providing proper training is so important.
Heat Safety Tips to Prevent Workplace Illness
When temperatures rise, small steps can make a big difference in keeping crews safe:
• Drink water regularly throughout the day, not just when you feel thirsty
• Take breaks in shaded or cooler areas when possible
• Start earlier or adjust schedules to avoid peak afternoon heat
• Wear lighter, breathable clothing when possible under PPE
• Keep an eye on each other since a buddy system helps catch warning signs early
• Allow time for workers to acclimate to working in the heat
• Know the symptoms like dizziness, confusion, nausea, or extreme fatigue
Why Heat Stress Is a Bigger Risk for Tower Crews
Tower crews face additional challenges when working in the heat that can increase the risk of heat-related illness.
• Limited ability to take breaks while working at height
• Harnesses and protective gear that can trap body heat
• Increased physical strain from climbing and positioning
• Direct sun exposure with little to no shade
These conditions make it even more important to plan ahead, stay alert, and make heat safety part of everyday work practices.
Stay Compliant with OSHA Heat Stress Guidelines
Under OSHA’s General Duty Clause, employers are responsible for providing a workplace free from recognized hazards, including heat-related risks.
That means taking steps like:
• Developing a heat safety plan
• Providing proper training for workers
• Making sure water, rest, and shade are available
• Monitoring conditions during extreme heat
Keeping up with these basics helps reduce risk and keeps your job site running safely.
Prepare Your Team Before Temperatures Rise
Prepare Your Team Before Temperatures Rise
Heat-related illness is preventable, but only if workers know what to look for and how to respond. Taking the time to plan ahead, train your crew, and reinforce safe habits can make a big difference once the summer heat sets in.
