Use of Fans and Evaluation at High Temperatures
Fans are a useful tool for improving air circulation and providing a cooling effect. By strategically placing fans in work areas, you can increase airflow, which helps cool you down by speeding up sweat evaporation and reducing the perceived temperature. Portable fans are especially handy because they can be moved around to suit different work environments.
When temperatures exceed 102°F, fans may become less effective, especially in high humidity. In such cases, fans can circulate hot, humid air, which may increase heat stress. When indoors, it's better to rely on air conditioning or ventilation, and regular checks should be made to ensure fans are used safely.
