Acetylene leak may have triggered blast on ONGC ship in Cochin Shipyard


  • The “tendency to bypass safety procedures and the overconfidence of workers” might have triggered fatal accident at the Cochin Shipyard.
  • A preliminary inspection points to a leak in the huge quantity of acetylene that was being stored (for welding work).
  • It is inflammable in the 3% to 100% range (meaning it triggers an explosion even when oxygen is absent).”
