"At the very least people should be looking over their workplace and plotting out their escape route if something like this happens."

Not just the workplace. When you go anywhere you should always ascertain all the exits you can. Not just for terrorism but for lots of other disaster scenarios such as a fire. The first rule of self defense is situational awareness.
