Effective handling of initial reports from the onset of a disruption can significantly affect the effectiveness of the response, and effective communication is only possible when the organization knows clearly what, when, with whom and how it should communicate; it should establish documented procedures for warning and communication and assign responsibility for internal communication between levels and functions including within the response structure; alerting interested parties and receiving, documenting and responding to their communications, which can include emergency contact details for employees; ensuring the availability of communication equipment and means; supporting structured communication with emergency responders; managing the organization's response to media reports consistently with its communication strategy; and keeping a record of the key facts of the incident, of what was done and of what was decided. It should ensure effective procedures and means for receiving, documenting and responding to warnings, alerts and external communications from national or regional risk advisory systems or similar; some organizations may need temporary dedicated facilities far enough from the affected site that the incident does not hinder them; special arrangements may be needed for people with particular needs such as the elderly and people with disabilities (ISO 22322 gives guidance on public warning content and channels); and because disruption can affect communication equipment, alternative means may be needed such as loudspeakers, staff notification systems, spare mobile phones, satellite phones and two-way radios.
