EMERGENCY DIESEL GENERATOR BEARING FAILURE & FIRE

On March 21, 2001, while performing a 24-hour test run of the #14 emergency diesel generator (EDG), the generator outboard bearing failed due to insufficient lubrication. The bearing heated to approximately 340 F (171 C), causing the paint on the bearing housing to ignite. The fire was extinguished using a handheld extinguisher in less than one minute. The EDG was shutdown without any further damage. An ALERT emergency classification was declared, but terminated approximately one minute later. The three other emergency diesel generators remained operable.
