We write the procedures that control change to process chemicals, technology, equipment and procedures
Management of Change
OSHA PSM 1910.119(l)
OSHA PSM 1910.119(l) is the change control element, and our team writes the procedures that manage every change other than a like for like replacement, whether it touches process chemicals, technology, equipment, procedures or facilities that affect a covered process. Under (l)(2) the change procedure has to address the technical basis for the change, its impact on safety and health, any modifications to operating procedures, the time period the change applies for and the authorisation required. Under (l)(3) the employees who operate the process must be informed of the change and trained on it. Under (l)(4) the process safety information and the operating procedures have to be updated. This element fails whenever change discipline lapses, through uncontrolled modifications, missed hazard analysis implications and training gaps, and almost every CSB major incident report names a change management failure among the root causes. We give you a system that does not let changes slip through.
How the study is executed
A structured, facilitated process that runs from scope definition through close out and produces defensible, actionable outputs.
Per (l)(1), define MOC eligible vs replacement in kind boundary, cover chemical, technology, equipment, procedural, organisational.
Per (l)(2), build workflow covering technical basis, impact, procedure modification, time period, authorisation hierarchy.
Per change type, specify mandatory PHA / SIL / FERA / HAC / PSSR re review, integrate with electronic MOC system.
Per (l)(3), notify affected employees and train on change, integrate with PSM (g) training programme.
Per (l)(4), update PSI and operating procedures before commissioning, enforce update before MOC closure.
Monthly MOC quality audit, RCA of MOC failures, integration with incident lessons learned.
What the study covers in full
Outcomes of Management of Change OSHA PSM 1910.119(l)
