2.4. Activation of the plan
The activation of a plan is not automatic. Health workers have to be trained for the processes involved. The mechanisms for implementing the response plan should be clearly formulated. Depending on nature of the disaster, different phases can be defined:
a) Alert phase: Once an emergency is occurs, a telephone chain should operate based on registered names, addresses and telephone numbers. There should be alternate mechanisms for contact in case of power outage or interruption of telephone service. The plan should include warning systems as a part of intersectoral plans for different types of emergency, so that the public can take preventive and protective measures in coordination with national disaster management agencies or civil defense institutions. Where appropriate, this may include evacuation to temporary shelters or camps.
b) Action phase: Using “action cards” (see below) each health staff members should review their roles and act accordingly. Regular in-service training is necessary so that the personnel involved remains up to date on their roles established in the plan.
c) Closing phase: After the emergency, an evaluation of the actions taken should be conducted, and necessary adjustments should be made to the plan based on the experience and lessons learned.
