Lesson Module A-9
Search and Secure


This module brings focus on the Search and Secure process.  At the conclusion of this effort the reader should be able to properly Search and Secure any APS enclosure.

The purpose of the Search and Secure procedure
is to ensure that no person remains inside an experiment station when the shutter is opened.

The PSS will not allow a shutter to be opened until a proper Search and Secure is performed.

  • Typically, only one person is allowed to conduct a Search and Secure at a time.
  • The Search and Secure must be completed within a defined time period (60-120 seconds).  If the procedure has not been completed before the time period ends, the procedure must be started again.
