What is PSM:
• Application of Management System Controls to a manufacturing or chemical process in
way that process hazards are identified understood and controlled so that process related
injuries and incidents are prevented.

Element 05: Training
To ensure that workers preform a task to a minimum standard, to maintain their proficiency, or to
upgrade their skills. Performance reviews determine when these actions are required.
What is Training?
• Practical instruction in job tasks or methods
• Enable workers to meet minimum performance standards
• Performed before the worker is allowed to perform the task on their own
• Followed by performance assurance to confirm that the worker is performing the tasks correctly
and that they posses the knowledge, skills, and abilities (KSAs) required for their position

Element 06: Contractor Safety
To ensure that contract workers work according to safe work practices and that they don’t increase
the operational risk of the facility
Piper Alpha:
• The safety valve which was removed earlier, was removed by a contractor that had been hired to
inspect/ test it.
• The contractor had not been trained properly in the safe work practices needed for the task.
• The incident investigation also determined that the inadequate emergency response training
given to contractors on the rig contributed to the high loss of life

Element 10: Management of Change
Activities not require MOC
Common weakness:
• Failure to recognize the need to manage change
• Failure to recognize change RCA of the MOC weaknesses:
• Intentionally by passing the MOC process • Lack of management support
• Inadequate risk review of the proposed change • Awkward or inefficient MOC program
• Failure to properly mange the risk of the change • Lack of awareness or understanding
• Failure to properly design the change
• Failure to install the change as designed
• Failure to notify personnel and update procedures/ other documents
