India faces another Himalayan tragedy as a methane burst in the Teesta Stage-VI tunnel killed 15 workers. Methane is a recognized hazard in this seismically active region. Crucial questions arise regarding risk assessment, gas detection, and ventilation safeguards. This incident underscores the perils of underground work, following prior disasters like the Meghalaya mine and Uttarakhand tunnel collapse. Hydropower projects in the fragile Himalayas, like Teesta-VI, carry inherent vulnerabilities. While rescue is paramount, the government must conduct a thorough, independent review to ensure environmental clearance conditions were strictly met, rather than viewing this as an isolated misfortune.
