Heat Stress Prevention

• Dehydration from prolonged heat exposure
• Heat exhaustion caused by high humidity or direct sun
• Reduced alertness leading to operational mistakes

Heat stress prevention is essential for outdoor crews, road workers, landscaping teams, and utility operators who spend long periods in direct sun. High temperatures can affect concentration, reaction time, and physical stamina. Even indoor industrial workers near boilers or hot equipment face similar hazards.

Workers often underestimate heat stress because early symptoms—like mild headaches or fatigue—can feel insignificant. Humidity makes it harder for the body to cool itself, and heavy PPE increases the strain. Teams should monitor their physical condition and take breaks before symptoms escalate.

Different industries require different heat controls. Construction and road crews may need scheduled shade breaks. Utility workers may rotate tasks to minimize exposure near hot vaults or asphalt areas. Manufacturing teams working near heat-producing equipment should ensure ventilation or cooling is functioning properly.

Encourage workers to drink water consistently, not just when thirsty. Crews should check each other for signs of confusion, heavy sweating, or dizziness. Prompt communication and early action can prevent serious medical emergencies like heat stroke.

• Drink water frequently, even before feeling thirsty.
• Take shaded or cool-area breaks at scheduled intervals.
• Watch coworkers for heat-related symptoms.
• Avoid excessive PPE layering when safe to do so.
