You’re screwed. Seriously. And it isn’t like you weren’t warned.
You could have had an emergency pack ready to go under your desk, in your trunk, and at home. Now in addition to staying safe, you’ll need to worry about finding water, food, and essential medications.
You could have discussed with your family where to meet up if communications lines were cut off. Is your wife safe? Are your kids going to stay at school, head for home, or possibly try and find you at work?
You could have paid more attention to emergency exits, and alternate emergency exits in case the original one became impassable. With lights out, and halls filling quicly with smoke, how will you find your way to safety?
