Keeping people safe during emergencies such as terrorist attacks involves changing behaviour as well as providing physical protection. The ways that people behave in emergencies can help or hinder survivability, particularly in crowded buildings where the potential for congestion and crush can be as dangerous as the original threat. For control rooms, understanding these behaviours can improve command and control and help more people to take the right kinds of protective action. In this session, Dr Aoife Hunt will explore the current thinking around responses to hostile threats, debunking myths about crowd behaviour in emergencies and discussing the practical implications for control rooms planning their response to terrorist attacks.
