Tips to help workers avoid heat illness
The U.S. National Oceanic and Atmospheric Administration (NOAA) notes heat is the number one weather-related killer in the U.S., and explains that excessive heat claims more lives each year than floods, lightning, tornadoes and hurricanes combined. NOAA provides additional detail on how heat impacts the human body at "The Hazards of Excessive Heat“.
To assist workers and employers, NOAA will be issuing heat alerts across the U.S. this summer. Each National Weather Service Weather Forecast Office will send, as needed, warnings for 1) excessive heat outlooks to be issued when the potential exists for an excessive heat event within 3-7 days; 2) excessive heat watches will be issued when conditions are favorable for an excessive heat event within12 to 48 hours; and, 3) excessive heat warnings/advisories will be issued when an excessive heat event is expected within 36 hours.
