Glass Ceiling Nearly Crushes Man To Death [VIDEO]

A man is lucky to be alive after a glass ceiling above him came crashing down near him.

Just as the man in this video closes a door, he apparently here's the ceiling cracking and looks up. It's then when he makes a run that may have saved his life.

A massive glass ceiling comes crashing down and luckily no one was hurt. Had this man NOT made a dash for safety, this could have been fatal.
