Narrow lanes at the collapse site made things difficult for the fire brigade and other rescue workers.
Thane municipal commissioner Aseem Gupta said: “Because of the narrow lanes neither the fire brigade vehicles nor ambulances could reach the spot. This delayed the rescue operations. Every building in Mumbra is dangerous and we never know what awaits us the next morning.
We have to take some steps now. We will see that the whole of Mumbra comes under a redevelopment plan.” Kantilal Waghmare, a social worker, said: “More than 70 percent buildings in Mumbra are very close to each other and this is what’s making the rescue work very difficult.”
Waghmare added that construction of buildings in Mumbra increased after 2007. “This fact has come to the notice of the corporation now. With such density things are going to be difficult for the authorities.”
