The fire department was out today

There was an over powering electrical smell in the area of our lab and server room. Soon after there was smoke it the back hall way. The fire department was called and it was soon discovered that the workers re-roofing the roof got some of their roofing stuff in the air return system of the building. Oh yes, a fun time was had by all. Five fire trunks responded. The top photo is what you might pray to see if you are ever stuck in a fire, hopefully that will never happen, but now you know.
