When should a mine fire be sealed?

A mine fire should be sealed whenever it is not reasonably safe to employ direct methods of fighting the fire because sealing is a strategy that helps to contain the fire and prevent it from spreading further. This decision is often based on the assessment of safety risks, presence of hazardous conditions, and the potential for the fire to endanger the lives of miners.

In situations where direct confrontation of the fire poses an immediate danger to personnel, sealing becomes a necessary alternative. This method involves closing off the area affected by the fire, thus restricting oxygen flow and reducing the potential for combustion. It is a precautionary measure that prioritizes the safety of mine workers while managing the fire incident effectively.

Sealing is not performed based solely on the absence of visible smoke or at all times, as certain conditions may warrant active firefighting measures. Additionally, it is not advisable to seal a fire if it can be safely extinguished through direct methods, as this may lead to unnecessary containment and the associated risks. Understanding when to seal a fire is an essential part of mine safety and emergency response protocols.
