Non-Emergency Station Access Procedures During Operations Mode

1.0 SCOPE

This document is intended to instruct the APS Floor Coordinators in the manner in which non-emergency access (during operations mode) into an experimental station shall be conducted when the operating PSS will not permit access. Non-emergency access is defined as no perceived threat to human life depends upon accessing the station. thus, non-emergency conditions are typically those where the need to access a station when the PSS has blocked such entry is derived from equipment protection issues.

2.0 PURPOSE

This document describes in detail the procedures to be followed when non-emergency access (during operations mode) is needed into a station when the operating PSS will not permit entry.

3.0 INITIAL CONDITIONS

3.1 PSS Status

The PSS is in a Serious Fault Condition with the station doors closed and locked by the PSS. Furthermore, the PSS Serious Fault/s will NOT reset and the PSS is ACIS Global On-Line. (This presumes that the PSS System Manager has been contacted and that permission has been given to reset the fault.)

3.2 Reason for Immediate Non-Emergency Access

There is a need to immediately access a station to protect equipment as requested by an APS User. The conditions are such that, waiting for response by PSS personnel will cause significant damage to equipment and/or major impact on the physics program.

4.0 NON-EMERGENCY STATION ACCESS PROCEDURES

4.1 Verify that the Front-End Shutters are closed via the beamline PSS USER panel. Note that the Front-End Shutters are labeled "Station A shutters" on the PSS USER panel (see figure below). Using the EPICS display "Beamline_Status.adl", confirm that ACIS also shows the front-end shutters as closed. Do not proceed unless all of these indicators show the front-end shutters as closed.

4.2 Take the PSS Global Off-Line as per standard procedures (see figure below).

4.3 Remove the lead seal on the automatic door open pneumatic control box. Open the control box door and push the door open button inside the pneumatic control box (see figure below).
