The Communication between the affected residents and the relevant government agencies is crucial,particularly during a flood event, as services such as evacuation and rescue operations,and the setting up of temporary shelters for the victims,must be established immediately.The Malaysian Red Crescent Society (MRCS) was usually among the first organisations to arrive at the flooded squatter communities as they need to co-ordinate the evacuation of the residents and to operate the temporary shelters.The gatekeepers of any hazard-prone communities would usually have in their possession the contact numbers of several MRCS officers whom they can call at any time of the day whenever necessary.
