For operations like oil and gas that involve hazardous processes, change management can be a matter of life and death. Operational failures resulting from insufficiently planned changes can result in catastrophic events.
That is why OSHA developed the Process Safety Management (PSM) of Highly Hazardous Chemicals Standard, which affects processes using high-risk materials, and includes regulatory requirements for these operations to develop and implement written Management of Change (MOC) procedures to manage changes to process chemicals, technology, equipment, procedures, or to facilities that perform a specific covered process.
