Permanently Closed - In the 1800's, “Safety Coffins" were invented equipped with a cord attached to a bell for communication to the outside world, should the interred be revived after burial. A housing unit around the bell above ground would prevent it from ringing accidentally. If the bell rang, the grave digger would pump air into the coffin to allow the occupant to survive until the casket could be dug up.
You have now found yourself buried alive! You have 15 minutes to repair the cord and ring the bell, notifying the grave digger you're still alive.
Who lives?....Who Dies?
