What should happen in the event of an accident to the ventilation fan?

In the event of an accident involving a ventilation fan, disconnecting the power and ordering miners to withdraw is critical for ensuring safety. Ventilation fans are essential in maintaining air quality and preventing the accumulation of harmful gases in underground environments. If an accident occurs, it may indicate a malfunction that could compromise air circulation. Disconnecting the power helps prevent any potential electrical hazards and further complications that could arise from the fan's operation.

Ordering miners to withdraw protects their health and safety, allowing them to escape from potentially hazardous conditions. This action ensures that they are no longer exposed to reduced ventilation and the risk of toxic gas buildup. It is vital to prioritize the safety of miners in these situations, as the ability to safely evacuate and assess the situation is crucial to preventing injury or loss of life.
