Beat the Heat: Staying Safe
While Working Outdoors
As temperatures rise throughout the summer, construction workers face an increased risk of heat related illness. According to the Occupational Safety and Health Administration (OSHA), millions of workers across the United States are exposed to heat on the job each year. While heat related illnesses are preventable, thousands of workers become sick annually, and some cases are fatal.
Construction workers are particularly vulnerable due to strenuous physical labor, direct sun exposure, heavy protective clothing, and the demands of working in hot environments. Heat illness can occur not only during heat waves, but anytime temperatures, humidity, and workload combine to overwhelm the body’s ability to cool itself.
OSHA recommends employers and workers remember three simple words: Water. Rest. Shade.
Workers should:
- Drink water frequently, even before feeling thirsty.
- Take regular breaks in shaded or air conditioned areas.
- Wear lightweight, breathable clothing whenever possible.
- Gradually build up to heavy work over several days to allow the body to acclimate to the heat.
- Watch for signs of heat exhaustion, including heavy sweating, dizziness, headache, nausea, muscle cramps, and weakness.
Workers should also look out for one another. If a coworker appears confused, loses consciousness, has seizures, or exhibits signs of heat stroke, call 911 immediately and begin cooling the individual while waiting for emergency medical personnel. Heat stroke is a life threatening emergency that requires immediate treatment.
Employers can help protect their workforce by scheduling strenuous tasks during cooler parts of the day, providing access to drinking water and shaded rest areas, encouraging frequent breaks, and training employees to recognize the symptoms of heat related illnesses.
As summer temperatures continue to climb, taking a few simple precautions can make all the difference. Staying hydrated, taking breaks, and recognizing the warning signs of heat illness can help ensure every worker returns home safely at the end of the day.
