Case the room
During the November 2015 attack on Paris’ Bataclan concert hall, a security guard led a group of people to safety through a fire exit left of the stage. But there won’t always be a guard to help. Whenever you plan on spending a lot of time in a public place, make a point of identifying emergency exits for yourself. The more prepared you are before an incident, the more quickly you can react if the time comes.
First, run from danger. Then …
In its report on “dynamic lockdowns,” the U.K. government’s advice is to run from danger if there is a safe route out. If you can’t run, hide. If you escape, immediately tell an official what’s happening, and warn others to avoid the danger zone. Separate from gathering crowds; always assume there’s going to be a secondary attack or action. This advice holds true across borders. Several weeks after the Paris attacks, the French government issued a safety poster that advises attack victims to “Flee, Hide, Alert.”
