Problems for SAR Teams
Assess the magnitude of the calamities.Collect information both official & non
official agencies for relief works.Ascertain resources available for relief ops.

Problems for SAR Teams.....
Coordination of various agencies for :– Evolving a common programme of work.– Drawing up operations plans– Providing facilities like training of
volunteers.– Establish liaison between Central & State
Governments, Local authorities & Social Welfare Organisiations.
