When temperatures in the sizzling Southwest America rise to
more than 100 degrees, the pavement can become hot enough to cause a second degree
burns on human skin in seconds.
In a new study published in the Journal of Burn Care & Research,
a team of surgeons from the UNLV School of Medicine looked at all the
Burning roadway admissions in an area of Las Vegas burn more than five
years. The team compared the outside temperatures at the time of each
the admission of the patient to, in essence, determine how hot it is too hot.
"Burns in the roadway represent a significant number of burns related to burns.
injured, particularly in the southwestern United States, "says the study
the authors wrote. "The pavement can be much hotter than the
room temperature in direct sunlight and can cause second degree burns
within two seconds. "
For this study, researchers identified 173 burns related to the roadway
between 2013 and 2017. Of this number, 149 were isolated roadways
burns and 24 other injuries, including those caused by motor vehicles
accidents.
More than 88% (153) of the related incidents occurred when agency workers were employed.
95 degrees or more, with the risk increasing exponentially to
temperatures exceeded 105 degrees.
This is because pavements exposed to direct sunlight absorb radiant energy,
making it significantly warmer and potentially dangerous. Authors of the study
say that the pavement on a day of 111 degrees, for example, can be as hot as
147 degrees in full sun. For reference, a fried egg becomes firm
at 158 degrees.
And even if it seems obvious to stay on a hot sidewalk, for
some are inevitable – including the victims of road accidents,
people with mobility problems or medical episodes that have fallen to the water
soil, or small children who may not know better.
Delivery – summer in the desert is not a joke, and more education
is needed to warn people of the risks badociated with hot roads, especially
temperatures slide above 100 degrees.
"This information is useful for burning centers in warmer climates, for
plan and prepare for coordination of care and treatment, "says study
lead author, Dr. Jorge Vega. "It can also be used for burns
prevention and public health awareness, including increased awareness
and additional training in emergency medical services and police
personnel when monitoring burn victims in the field ".
The study entitled "Five-Year Review of Burns in the Causeway of a Desert" was published in the July / August 2019 issue of the Journal of Burn Care & Research. [WARNING: study contains graphic imagery]
