Outdoor workers who are exposed to hot and humid conditions are at risk of
heat-related illness. The risk of heat-related illness becomes greater as the
weather gets hotter and more humid. This situation is particularly serious when
hot weather arrives suddenly early in the season, before workers have had a
chance to adapt to warm weather. For people working outdoors in hot weather,
both air temperature and humidity affect how hot they feel.

As summer approaches and outdoor temperatures begin to rise, the US
Occupational Safety and Health Administration (OSHA) is once again informing
the public about its Heat Safety Tool app to help protect workers from heat
illness, which is available on iOS and Android devices in both English and
Spanish.

OSHA has updated the version for iPhones, which now offers full screen color
alerts for all heat conditions, improved navigation and accessibility options,
and compatibility upgrades. The heat app provides heat illness prevention
guidance specific to the user's current outdoor workplace conditions using
weather data provided by the National Oceanic and Atmospheric Administration.
The new version provides the daily maximum heat index intended to help prepare
for extreme heat and plan work schedules accordingly. More than 187,000 users
have downloaded this life-saving app.

OSHA's heat app was updated in-house and is fully open source, so app
developers from across the country can access the code and contribute to or
improve the app themselves. The heat app's code is available online.
