Heat Illness
Any individual, regardless of age, sex or health status can develop heat stress if they are engaged in intense physical activity and/or exposed to environmental heat (and humidity). If heat exposure exceeds the physiologic capacity of the body to cool itself, and core body temperature rises, then a range of heat-related symptoms and conditions can develop – from relatively minor treatable heat cramps to severe life threatening heat stroke, which is always an extreme medical emergency. Even when acclimatized, adequate hydration is critical to avoid of development of heat-related illness.
In order to prevent heat illness in employees, supervisors must monitor weather conditions, including projected temperatures and humidity.
Possible Indicators of Heat Illness

- Confusion
- Slurred speech
- Seizures
- Fainting
