When a building emergency occurs, it is not always sufficient to simply initiate alarm bells. Individuals may not know what the alarm bell means and as a result may respond inappropriately to its sound. Many buildings have installed mass notification or emergency communication systems, based upon requirements provided in international codes and standards, that can be used to disseminate audible or visually-provided information in the event of an emergency. However, there is a lack of guidance on how to use current emergency communication systems in the most effective manner. For example, buildings often use these systems to disseminate pre-recorded, general emergency voice alarm messages that leave occupants wanting and needing further information before effectively responding. Especially as the use of newer technologies such as mobile devices or social networking tools grows, guidance on message content and dissemination becomes even more critical to ensure effective and safe response of building occupants during an emergency.
