Introduction
Disasters, terrorist attacks and other major incidents need an effective incident response in order to
save lives, mitigate harm and damage. Emergency response organizations need to respond quickly to a
developing emergency situation. Time to communicate is limited and often a specific message involving
practical action is to be disseminated to a large group. Simple procedures that send the message
efficiently and create the desired response can save lives, protect health and prevent major disruptions.
The protection of people at risk from harm is an important part of an incident response. Public warning
enables response organizations to alert their responders and allows people at risk to take safety
measures to reduce the impact of incidents. Effective public warning consisting of alert and notification
can prevent panic reactions and support response organizations in optimizing their responses and
mitigating the impact.
Effective incident response needs a structured and pre-planned public warning. Public warning is
based on two functions: hazard monitoring and warning dissemination. It is also necessary to establish
a mechanism for risk identification, hazard monitoring, decision-making and warning dissemination,
and to evaluate and improve.

Figure 1 — Overview of the public warning system
The organization should assess the potential hazards that can occur within a defined area and the
level of potential risk each presents. The results of this assessment should determine the type of public
warning that can be required and should be documented for future reference. The public warning
system developed by the organization should:
a) provide the framework for setting and reviewing public warning objectives;
b) be planned in advance;
c) be documented, implemented and maintained;
d) have the human and technical resources to plan, implement, maintain and improve the public
warning system;
e) be communicated to all persons working for or on behalf of the organization;
f) provide suitable training for responders;
g) be available and communicated to the public generally and especially to the people at potential
risk;
h) involve appropriate consultation with community representatives (this may include, but not be
limited to, community groups, mutual aid networks, political representatives, charities and non-
governmental organizations (NGOs), trade, and business associations) or bodies concerned with
public interests;
i) include a commitment to continual improvement.

parties who are individual experts, groups of experts, or organizations in the private or public sectors
at the local up to the international level. Those who contribute to both functions should:
a) be familiar with the capabilities and capacities of the public warning system so that relevant,
accurate, reliable and timely warnings will be disseminated;
b) make continuous effort to raise and maintain public awareness (see Annex B);
c) specify safety actions within the warning.
4.2.2 Hazard monitoring function
Hazard monitoring is based on the risk assessment conducted to determine the hazards to be monitored.
Those involved in the hazard monitoring function are responsible for the following:
a) understanding hazard monitoring operations from local up to international agencies and having
channels to communicate with them;
b) ongoing monitoring of identified risks within a defined area and within their range of expertise;
c) providing early information on emergin
