Here is a link to a fairly recent incident resulting in an explosion completely destroying the chamber:

The NASA fire being discussed earlier in the thread was one of the first incidents of 100% O2 environment fires, it occured during the Apollo program and resulted in the loss of three astronauts.

In the months following the tragedy a crew of Air Force soldiers attempted to duplicate the conditions leading to the accident.
The O2 safe procedures established during these studies extended beyond the space program and resulting in modification of military hyperbaric safety procedures, many of these procedures are still in use today.
