Lessons Learned - Displaced Heating, Ventilating, Air Conditioning (HVAC) Controls
Year: 1992
Abstract: Description of Driving Event:
The HVAC chilled water boost pumps are located on the 120-foot level of the rotating service structure (RSS). The start/stop controls and circuit breakers (disconnects) providing power to the pumps are located in the motor control center at the RSS 215-foot level; therefore, there is no local control. When maintenance personnel are working on the pumps, a possibility exists that someone could re-apply power. The start/stop controls and circuit breakers can not be locked out, physically, to prevent inadvertant actuation.
