Why is the rescue operation in Silkyara tunnel considered dangerous and expected to take a long time

The rescue operation in Silkyara tunnel is considered dangerous and expected to take a long time due to several risks and challenges. Here are the main reasons:

• Collapsed tunnel: The tunnel has suffered a collapse, making it unstable and prone to further cave-ins, posing a threat to rescuers and delaying progress.
• Inaccessibility: The tunnel is located in a remote area, making it difficult for rescue teams to bring in heavy equipment and resources necessary for the operation.
• Limited visibility: Poor lighting conditions and thick smoke inside the tunnel hinder visibility, making it challenging for rescuers to navigate and locate trapped individuals.
• Air quality: The tunnel has poor ventilation, leading to a high concentration of harmful gases and suffocating conditions for both trapped individuals and rescuers.
• Rescue technique: The limited space within the tunnel makes it difficult to employ traditional rescue techniques, increasing the complexity and time required for the operation.

Considering these risks and challenges, experts estimate that the rescue operation in Silkyara tunnel could take a considerable amount of time, possibly lasting several days or weeks, depending on the progress made.
