What must be done if an auxiliary fan fails or stops?

When an auxiliary fan fails or stops, it is essential to stop any electrical equipment and disconnect power until ventilation is restored. This is critical because auxiliary fans play a key role in providing adequate ventilation, especially in areas where hazardous gases or conditions might be present. Continuing operation of equipment without proper ventilation could lead to dangerous situations, including the buildup of toxic gases or a deficiency of breathable air.

Disconnecting power ensures the safety of personnel and prevents further complications that could arise from an environment lacking proper airflow. Once the corrective actions are taken, such as assessing the fan for repairs or determining a suitable alternative ventilation method, the system can then safely resume functioning. This protocol adheres to safety regulations and practices necessary in any industrial or mining environment where ventilation is crucial for health and safety.
