IR 1396014:
LIGHT FIXTURE CONNECTION DEFICIENCY During the Seismic Walkdowns it was identified that a light fixture just west of the 3A Hx in the SE LPCI Comer Room had a detached chain on one side of the fixture. However, the other chain at the same end of the fixture was securely attached and the two chains at the other end of the fixture were also securely attached. Therefore, the fixture is judged to be acceptable.
