What is the primary purpose of the Management of Change element in a risk-based process safety management system?

• A. To document compliance
• B. To manage risk
• C. To increase production
• D. To lower maintenance cost

Answer: (B)

The main idea behind Management of Change is to ensure that any proposed change to a process, equipment, chemical, procedure, or personnel is evaluated for safety impact before it is put into place. It requires identifying the potential hazards and assessing the risk that the change could introduce or worsen, then getting the right approvals, implementing safeguards, training staff, and updating procedures. The goal is to prevent new hazards or increased risk, keeping the process safely under control.

For example, changing a material or operating condition could alter flammability, reactivity, or release pathways; through MOC, you would analyze these changes, adjust controls, communicate the plan, and verify that the safeguards still work.

Documenting compliance and aiming to increase production or cut maintenance costs might accompany changes, but they are not the primary purpose of MOC. The essential aim is to manage risk posed by any change to the process safety system.
