In recognition of National Heatstroke Prevention Day, we explore heat symptoms and proactive measures to minimize illnesses and injuries. Heat exposure is the primary cause of U.S. weather-related fatalities and poses serious risks in the workplace.
Understanding Heat Hazards
Most fatalities occur during the first days of hot weather. Workers often engage in strenuous activity and their body may not cool down through sweat and blood flow due to heat. Their internal temperature increases and causes exhaustion, strokes, and severe illness. These effects can happen outside, in buildings, vehicles, and during any season depending on factors. Remember to take the sun, humidity, time of day, work activity, and hydration into account to reduce heat risk.
Preventive Work Measures
Reducing heat hazards can save lives. Make sure to adjust work schedules to minimize exposure during peak hours and tune into your local weather station to plan appropriately.
Arrive at work hydrated and drink a cup of water and liquids every 15-20 minutes. Avoid identifying thirst as the only dehydration sign—other indications include dry skin, dizziness, and fatigue. Take breaks in shade and recover with water, fans, and food to replenish electrolytes. Wear a sun hat and comfortable clothing—know that personal protective equipment (PPE) may increase heat risks. Report any conditions and concerns to a supervisor.
Organizations should incorporate heat-symptom identification and response into First Aid training. Work with a partner and monitor symptoms, including increased pulse, hot or irritated skin, confusion, and loss of consciousness. Call emergency services if signs worsen, and seek shade or cool shelter, remove outer garments, drink water, and place ice packs on skin.
