Tunnel collapse in India kills 12 workers

A tunnel collapse in India’s Sikkim state has resulted in the deaths of 14 workers, according to local authorities. The incident occurred on Monday when a section of an under-construction tunnel collapsed following a gas explosion. Rescue efforts continue to locate 13 additional workers believed to still be trapped within the structure. The tunnel, part of a larger infrastructure project, was intended to transport water from the Teesta River to a hydropower plant operated by the state-owned National Hydroelectric Power Corporation (NHPC). The site is located in the Himalayan region of Sikkim, known for its rugged terrain and ongoing development projects aimed at boosting energy production. The tunnel was approximately 1.5 kilometers from the entrance when the disaster struck. According to NHPC, the explosion was triggered by a sudden release of suspected methane gas trapped within the rock formations. Methane, a naturally occurring gas, can accumulate in enclosed spaces such as tunnels during excavation. When released and exposed to an ignition source, such as sparks from machinery or electrical equipment, it can lead to explosive conditions. A government official confirmed this explanation, noting that the presence of methane in the area was not unusual. At the time of the incident, 27 workers were present in different sections of the tunnel. Two individuals managed to escape unharmed, while the remaining 25 were trapped. As of Wednesday, rescue teams had recovered 12 bodies, with efforts ongoing to locate the remaining 13. The National Disaster Response Force (NDRF) has been deployed to assist in the search, focusing on a 200-meter segment of the tunnel where survivors are thought to be located. Police reports indicate that seven of the deceased have been identified. Among them, one individual is from Sikkim, while the rest are migrant laborers hailing from West Bengal, Uttarakhand, and Assam. Post-mortem examinations are scheduled to determine the exact causes of death. Authorities have emphasized that the identification process is ongoing, and further information may emerge as investigations progress. In response to the tragedy, Chief Minister Prem Singh Tamang has established a special investigation team to examine the circumstances surrounding the incident. “We have engaged a team of experts to find out what exactly happened and how,” he stated during a press briefing. “We will take action on the basis of the findings.” This move underscores the government’s commitment to understanding the root causes of the disaster and implementing preventive measures to avoid similar incidents in the future. The Sikkim government has also issued statements attributing the accident to methane gas combustion, aligning with the explanation provided by NHPC. Officials have reiterated the need for strict adherence to safety protocols in high-risk environments such as tunnel construction sites. With ongoing rescue operations and forensic investigations underway, the focus remains on ensuring the safety of workers and preventing future occurrences of such tragedies.
