ABSTRACT
On September 11, 2001, over 3,000 people died in the terrorist attack on the World Trade Center (WTC) in New York. Since the attack, concern about terrorism resonates in the hearts and minds of everyone, especially emergency responders and security professionals. In fact, this catastrophic incident signifi cantly changed the traditional roles of emergency responders and security professionals around the world, resulting in a paradigm shift in the
security industry. Th e attack on the trade center made it apparent that any person, location, or work environment is a possible target of terrorists. Public and private security professionals scrambled to implement immediate changes in security measures, being sure to incorporate the latest technology. For example, as part of a global program to improve security and lessen workforce anxiety, New York-based Lehman Brothers provided personal safety emergency kits with every personal computer (PC) and workstation. Th e global head of security operations at Lehman Brothers reported that each kit contained a gas mask, safety goggles, and a whistle, which would be used to signal for assistance during an evacuation (Vernon, 2003).
