Alarmed after the recent Uttarkashi Silkyara tunnel incident and with a firm commitment to ensure the highest safety standards, the National Highway Authority of India (NHAI) on Friday announced plans for a thorough inspection and safety audit for 12 under-construction tunnels in Himachal Pradesh.

The NHAI is in the process of enlisting a third party to carry out the audit, focusing on crucial aspects such as rock stability, construction materials, and emergency response mechanisms.

NHAI regional officer Abdul Basit, in a statement on Friday, highlighted the need for proactive safety measures in light of the Uttarkashi incident where 41 workers have been trapped for the past 13 days. The safety audit aims to identify potential risks and implement remedial actions to prevent similar occurrences.

Emphasizing the significance of the third-party involvement, Basit said that an independent assessment would provide an unbiased evaluation of construction processes, materials used, and overall safety preparedness. This approach ensures transparency and thorough scrutiny of the ongoing tunnel projects.

The safety audit, which is yet to be conducted, will cover a range of factors, including assessments of rock stability and scrutiny of construction materials. Additionally, the audit will evaluate emergency response protocols to ensure a swift and effective response in unforeseen circumstances.

To further enhance safety measures, vertical drilling machines are expected to be strategically stationed near the tunnels. These machines will be readily available for use in emergencies, aligning with the NHAI's proactive approach to address potential risks.

Basit suggested placing vertical pipes at tunnel construction locations, allowing for the supply of oxygen and food in case of emergencies. This additional safety measure aims to ensure the well-being of workers involved in the construction.

NHAI officials are gearing up for the upcoming safety audit, with plans to conduct visits to under-construction tunnels, engaging with workers and directing contractors to maintain a list of machinery available in nearby areas. This strategic approach ensures that essential machinery can be quickly mobilized to the site in case of an emergency, minimizing response time.

Basit issued a stern warning against any laxity in safety standards and instructed project directors to conduct regular mock drills. These drills are crucial for evaluating the preparedness of evacuation plans and the efficiency of emergency response procedures.
