Have you ever had the chance to look into formal documentation made by emergency or crisis responders at on-scene-command or in command centres? Have you payed attention to the amount of temporary and temporal contact information that they need to handle? Such temporal contact information is typically names of people and their associated mobile phone numbers. The importance of these temporal contact information should not be underestimated for the ability of organizing response work. However, the temporal contact information is often difficult to distributed across the response network, and contact information is typically gathered at different geographical locations. In a project by the Public Safety Research Group, we address this phenomena and will in the next few weeks conduct field experiments with incident commanders and command centre staff to further explore how to support the management of temporal contact information. Stay put and we will tell you more just before the summer.
