## Narrative

An operator initiated start-up procedures on the #5 calciner.  He started the exhaust and tempering blowers.  An ignition occurred.  While the unit was down, bunker C had vaporized and collected in the upper calciner compartment.  When tempering air was added, it provided additional oxygen to an already hot compartment resulting in the ignition.  Estimated cost to repair, $30,000.
