The following training issues should be evaluated carefully for applicability to new SACs, and
existing SACs, as defined in this Standard.
Personnel Selection: The minimum qualification and experience requirements of the personnel
performing the task should be considered carefully when formulating, implementing, and
maintaining SACs. Some SACs may require operators with special knowledge, skills, or
physical abilities. In the combustible loading example previously noted, such a control will
require an individual with specialized knowledge and experience in assessing the fire hazards in
an area. Some controls rely on the ability of the operator to distinguish color differences, to
perform strenuous tasks, or gain access to relatively inaccessible areas. These specific factors
must be considered explicitly in the formulation, implementation, and maintenance of SACs.
Job Task Analysis: The formulation of SACs should include a thorough job task analysis (JTA).
A JTA will identify the required plant instrumentation, physical controls, operator skills and
abilities, and other important variables necessary to successfully perform the task. The JTA
should include or incorporate the appropriate human factors considerations in developing the
Initial Qualification Requirements: Depending on the results of the JTA, the operator training
and qualification requirements for tasks related to SACs should then be developed. The
training requirements should account for and disposition each important variable in the JTA,
hazard analysis, or other basis documents being used to develop the SAC. Many hazard and
accident analyses contain assumptions (both implicit as well as explicit) regarding the ability of
the operators to detect and respond to accident scenarios. It is important to identify clearly
these assumptions so that operators are specifically trained with respect to the SACs that are
credited in the analysis. The training program should identify explicitly the required training for
SACs. Additionally, consideration must be given to the development of formal written and
practical examination requirements for these ACs.
Continuing training requirements: In addition to formal, initial training requirements, the
knowledge and skills set for SACs should be considered for inclusion in a continuing training
program. This will ensure that the important training objectives for the controls are periodically
reinforced to plant operators, supervisors, and managers. Additionally, such learning objectives
should be considered in formal, periodic re-qualification programs.
