What is a contributing risk factor for heat-related illness while working outdoors?

1. Work in extreme temperatures

2. Physical inactivity

3. Poor ventilation

4. Heavy equipment usage

The correct answer is: Work in extreme temperatures

The choice of extreme temperatures as a contributing risk factor for heat-related illness while working outdoors is valid because exposure to high temperatures can significantly increase the risk of heat-related conditions such as heat exhaustion and heat stroke. When individuals work in environments where ambient temperatures are elevated, their bodies must expend extra energy to regulate internal temperatures. This can lead to dehydration and an inability to cool down effectively, thus heightening the risk of heat-related illnesses. The other options, while they may contribute to workplace safety and health, do not directly relate to heat stress in the same primary way that extreme temperatures do. For example, poor ventilation might affect air quality but does not specifically address the direct effects of high heat on the body. Similarly, physical inactivity and heavy equipment usage may relate more to other forms of strain or injury rather than the heat stress associated with high temperatures.
