\item The \opsfull{} directs operations procedures and communicates with the other test personnel.
\item The \primaryfull{} is the main system operator. \primary{} operates all manual valves as well as the test control system.
\item The \secondaryfull{} is the backup for \primary{}, and communicates with OPS. If \primary{} becomes incapacitated, \secondary{} is responsible for removing them from danger.
\item The \daqfull{} monitors and operates the test data acquisition system.
\item the \controlfull{} operates the test control system, including actuation of remote valves.
\item The \heatfull{} operates the valves for the tank heating system.
\item \perifull{}, \periifull{}, and \periiifull{} ensure that no unauthorized personnel enter the testing area during test operations.
