The National Weather
Service uses a "heat index" that alerts the public when combinations of
heat and humidity could make hotweather hazardous. Also included
is a list of heat stress symptoms and the appropriate first aid.
This document describes the procedures for investigating
incidence of heat stress in operations that pose a high risk for inducing
heat stress. In addition, this document offers solutions on how to
prevent heat stress in these environments.
