The correct answers are B, C, and E because these represent organizational changes that can significantly impact process safety risk , and therefore require a Management of Organizational Change (MOOC) review as defined by CCPS under the RBPS framework.
MOOC focuses on evaluating how changes in staffing, structure, roles, responsibilities, or working conditions may affect hazard control, decision-making, supervision, and operational reliability.
B (Replacing maintenance with contractors) introduces risks related to competency, training, communication, and familiarity with site hazards , which are critical CCPS concerns.
C (Reducing number of operators) directly affects workload, fatigue, ability to respond to abnormal situations, and supervision , all of which are key human factor risks.
E (Changing shift length from 8 to 12 hours) impacts fatigue, alertness, and human performance reliability , which CCPS identifies as major contributors to incidents.
The incorrect options are less impactful:
A (moving operator within same unit) does not significantly change organizational risk if competency remains equivalent.
D (office to cubicle relocation) has negligible effect on process safety.
CCPS emphasizes that organizational changes must be treated with the same rigor as technical changes , because many major incidents have been linked to staffing reductions, contractor use, and fatigue-related performance degradation.
