IR 1396562:
UNPINNED SWITCHGEAR HOISTS During Fukushima seismic walkdowns, two movable trolley hoists mounted on top of SWGR 38 and one movable trolley hoist mounted on top of SWGR 39 were found unrestrained against horizontal movement due to the restraining pin for each hoist not being installed while each hoist was in the stored position. The switchgears are located at U3, N-47, EL. 570.
Unit supervisor and shift manager were informed of the condition and station personnel installed the pins for the trolley hoists. Therefore, hoists are judged acceptable.

Are overhead equipment, distribution systems, ceiling tiles and lighting, and masonry block walls not likely to collapse onto the equipment?
Overhead light fixture judged to be acceptable.
