What action is required if ventilation is restored within fifteen minutes?

Restoring ventilation within fifteen minutes typically indicates that the emergency situation may have been temporarily resolved, but it is crucial to ensure that the environment is safe before proceeding. Conducting a re-examination of the face regions and affected areas is essential to verify that air quality and conditions are acceptable for miners to return safely. This step helps identify any lingering hazards that may not be immediately obvious and allows for appropriate measures to be taken to ensure a safe work environment.

The decision to recheck these areas ensures that any potential impacts on worker safety are assessed thoroughly, including checking for gases or other hazardous conditions that could arise even when airflow is restored. This diligent approach safeguards against unexpected risks, respecting the health and safety protocols typically mandated in underground mining operations.

While other options might seem applicable, they do not prioritize the necessary assessment of safety conditions after ventilation has been restored.
