A T Au a, . ,== es a e . see,..., ev ee .,,,e- ,,,,e., n ei A walk down was performed on fire dampers and those listed below were found which did not meet UL fire rating requirements, thus violating Tech Spec 3/4.7.7. The system remained fully functional even though the dampers were not in compliance with UL standards. Thus potential consequences were minimal. Damper identification: WMA-FD-1,

-2, -3, -6, -7, -8, -9, -10, -11, -14, and DRA-FD-34-1.

This was due to personnel error when reading the associated drawings. Dampers WMA-FD-3 and 6 were originally reported as WMA-FD-18 and 15 respectively. The modification made to the dampers was minor cutting to obtain the size required to allow installation into the existing duct work. This cutting, however, voided the U.L. fire rating of the dampers, thus violating Technical Specification 3/4.7.7, which requires all fire rated assemblies to be operable at all times.

Corrective Action:

A fire watch has been established to monitor the affected areas.

Each modified damper is being removed and replaced with a U.L. approved damper.
