Every year, National Heat Awareness Day serves as an important reminder that heat exposure isn’t just uncomfortable — it can be deadly. According to the National Weather Service (NWS), more workers die from heat-related illnesses each year than from hurricanes, lightning, or tornadoes combined.
Whether you’re working outdoors under the sun or indoors in high-temperature environments, understanding the risks of heat stress and how to prevent it can save lives.
Recognizing the Signs of Heat Stress
Supervisors and employees alike should stay alert to early warning signs of heat exhaustion and heat stroke. The faster symptoms are recognized, the more likely serious illness can be prevented.
Common Symptoms to Watch For:
- Dizziness or confusion
- Nausea or vomiting
- Heavy sweating
- Extreme thirst
- Muscle weakness or cramps
- Headache or fatigue
- Loss of consciousness
Workers over 65, those with underlying heart conditions, high blood pressure, or on certain medications are especially vulnerable to heat-related illnesses.
If any of these symptoms appear, move the worker to a cool area immediately, provide water, loosen clothing, and seek medical help if symptoms persist.
How Employers Can Protect Workers
The Occupational Safety and Health Administration (OSHA) emphasizes that heat-related illnesses are entirely preventable. Employers should take proactive steps to minimize risks and educate their teams before the summer heat peaks.
Best Practices for Heat Safety:
- Provide Regular Breaks: Allow time for rest and cooling down, especially during peak heat hours.
- Ensure Access to Water and Shade: Hydration and shaded rest areas should always be available.
- Monitor Environmental Conditions: Use the heat index to gauge risk levels and adjust workloads or schedules accordingly.
- Train Employees: Conduct safety training on recognizing symptoms of heat stress and how to respond quickly.
- Encourage a “Buddy System”: Have workers look out for one another and report early signs of heat illness.
Why Heat Safety Matters Year-Round
Heat safety isn’t limited to summer. Indoor environments like warehouses, foundries, and manufacturing facilities can also expose employees to high heat year-round. Employers should ensure proper ventilation, air movement, and emergency response procedures are in place regardless of the season.
A Simple Reminder Beyond the Workplace
Outside of work, remember:
- Never leave children or pets unattended in a parked car, even for a few minutes. Temperatures can rise to dangerous levels in seconds.
- Stay hydrated, take breaks, and check in on neighbors or family members who may be at risk during heat waves.
