The civic administration and the police will conduct a mic campaign on Wednesday to try and convince people living in dilapidated structures and shanties to move to designated shelters.

During a video conference on Tuesday, chief minister Mamata Banerjee asked Firhad Hakim, the chairman of the Calcutta Municipal Corporation’s board of administrators, to persuade all residents of dilapidated buildings to shift to shelters.

Teams have been deployed in different parts of the city to remove fallen branches, uprooted trees or toppled lamp posts and rescue people from under the debris of buildings.

A large number of officials and engineers of the Calcutta Municipal Corporation will be stationed in office between Wednesday and Thursday morning, when the effect of Cyclone Amphan is likely to be felt in Calcutta and its neighbouring cities.

The CMC has issued an advisory to builders to ensure there are no loose ends in scaffoldings and labourers do not work on upper floors or in exposed parts of a proj-ect. “Cranes must be properly secured,” a CMC official said.

Each borough in Calcutta will have a team to remove uprooted trees and poles. Besides, there will be two central teams. The city police, too, are keeping five or six teams ready to cut trees and rescue people from under collapsed houses.

The police will also have a fleet of rescue boats that will have two life savers each.

Officials said portable pumps have been kept in low-lying and waterlogging-prone areas. “We have kept 290 portable pumps ready,” said a CMC official.
