Imagine if Jurong Islands pipe bust and burn. Same or worst situation will happen. Because just less than 15 km from CDB. If wind blow from west to east whole Singapore sky will be black smoke.
Will burn for months if not control.
Under ground more safer those tank on the surface is the most dangerous in US history the storage tank part can be blow away more than 100km. Where can we hide. Best is drive up north and stay in KL until situation under control.
Even plane cannot fly because of thick smoke.
