Today at work we had to sit through an hour long training on Fire Evacuation. This is important because we work in what the fire department calls an "Assembly Venue". This includes restaurants, theaters, sports stadiums, libraries, movie theaters. Basically places where people assemble.
One of the things that happens is that all these people come in through a main entrance but in an emergency it may not be possible for everyone to leave through one entrance quickly. That is why it is important for all employees to be aware of alternate exits.
At the end of the training my friend and I got up and exited out one of the "alternate exits". Everyone else got up went out the "main entrance". Barb and I got back to work a whole two minutes faster than everyone else. In a real crisis we would totally rock and would have to lead people to safety.
