Let's hope there's never a fire!

Walking through NYC to get lunch I came across this building and was curious what it said on the door. If I didn't have to get back to work right away, I may have tested it out, but hopefully for anyone who works there, it's just a sypo (sign typo).

How confusing is THIS?

But come to think of it, if you did work there you'd at least have a good reason for not showing up to work!
