Heat illness sickens thousands of workers every year, and severe cases can be
fatal.

The body normally cools itself by sweating. During hot weather, especially with
high humidity, sweating isn't enough. Body temperature can rise to dangerous
levels if precautions are not taken such as drinking water frequently and
resting in the shade or air conditioning. Heat illnesses range from heat rash
and heat cramps to heat exhaustion and heat stroke. Heat stroke requires
immediate medical attention and can result in death.

To help keep outdoor workers cool, the US-American Occupational Safety and
Health Administration developed a free app to calculate worksite heat index and
risk levels, and educate users about how to respond to a heat emergency.

With an attractive, easy-to-use interface, the new version is optimized for the
latest iPhones. The app automatically provides the current conditions and
maximum heat at your location and can accept manual input if users don't have
cell service.
