APS TECHNICAL UPDATE - No. 14
Subject: Experiment Hall Free of Obstruction above 15'
The APS requires access to facilities on the Experiment Hall ceiling for routine maintenance, such as changing light bulbs, maintaining HVAC blowers and filters, and the repair of utilities systems. The APS seeks to minimize the impact on beamline operations of these maintenance activities. As floor space within a sector is at a premium, a variety of means will be required to gain access to the ceiling including: access from the sector-dividing aisles, the top of the experimental stations, the top of the storage ring shielding, and the floor within the sectors.
In order to permit the use of man lifts that can be maneuvered above the beamline facilities, the airspace above these areas needs to remain free of obstructions. Towards this end, users should keep in mind the following design/installation criteria:
In the APS Experiment Hall, the airspace between 15' and 21' above the Experiment Hall floor, is to remain free of obstructions. This will provide enough elevation for a worker on a man lift to work below the facilities mounted on the Experiment Hall ceiling. Any installation that intrudes into the space above the 15' elevation requires APS approval. Inquires are to be directed to Steve Davey. As a reminder, all permanent installations at the APS require review and approval (see APS User Policies and Procedures).
