Recognizing Heat Illness in the Workplace

Why it matters

Heat-related illness can strike quickly—especially during summer. Whether working outdoors or in hot indoor environments, knowing how to identify and respond to early symptoms can prevent serious health consequences, including heat stroke and even death.

Heat illness exists on a spectrum, from mild symptoms to life-threatening emergencies. 
Early recognition saves lives.

Spot the warning signs

• Complaints of weakness, or headache
• Sudden disorientation or confusion
• Vomiting or inability to drink fluids
• Lack of sweating despite heat exposure
• Changes in behavior or alertness

Prevention is key

• Hydration: Encourage frequent water breaks.
• Dress code: Allow breathable, sun-protective clothing.
• Break schedules: Rotate tasks and increase rest.
• Acclimatization: Gradually increase exposure for new or returning employees.
