During the war against Pakistan in 1965 and Bangladesh liberation war in 1971, the Civil Defence Organisation worked effectively by mobilizing trained volunteers and by boosting the morale of the people. The local CD officers played a vital role in the functioning of refugee camps set up in different parts of West Bengal for the refugees of Bangladesh. Civil Defence services were also effectively engaged in management of flood, water logging, building collapse and railway accident etc.
Presently all the 18 districts and Kolkata area are under CD areas. Recently the Govt. of West Bengal included Bankura as CD district. We have all the services starting from Communication Service, Warden Service, Casualty Service, Rescue Service, Welfare Service, Supply Service, Depot & Transport Service & Training Service.
