description abstractDescription of Driving Event:
Construction personnel were performing renovations to room 194 in building 16A at JSC. The renovation project included installing a suspended ceiling in part of the room. While in process of installing the ceiling, a pipefitter for the facility construction contractor noticed that the fire suppression system sprinkler head fusible link guard on one head was not consistent with the other heads in the room. Since the sprinkler would not operate effectively with this misalignment, the pipefitter tried to correct the problem. As he was attempting to adjust the misaligned guard, the wrench slipped breaking the fusible link on the sprinkler head causing water to be discharged into the room. Although the water pressure was immediately shut off, the broken head continued to drain water for approximately 30 minutes.
