What potential health hazard is associated with inadequate ventilation when working in waterproof Tyvek suits?

Inadequate ventilation when working in waterproof Tyvek suits can lead to heat exhaustion due to the restricted airflow within the suit. These suits are designed to prevent the penetration of hazardous materials, including lead dust, but they also trap heat and moisture against the skin. As the body generates heat through physical activity, an inability to dissipate this heat can cause the core body temperature to rise. When the body overheats, it can result in heat-related illnesses, with heat exhaustion being a common outcome characterized by symptoms such as heavy sweating, weakness, dizziness, and potential loss of consciousness. Ensuring proper ventilation and hydration is crucial for workers in such environments to prevent these serious health issues.
