Management of Change (RBPS Element 13)

Governance of engineering, organisational and procedural change with PHA, SIL and fire and explosion triggers

What this study delivers

Management of Change
(RBPS Element 13)

Management of Change is the gatekeeper that stops uncontrolled modifications from collapsing your risk control framework. The element maps to OSHA PSM 1910.119(l) and covers any change to chemicals, technology, equipment, procedures, organisation or operating conditions, with the single exception of replacement in kind. What separates good management of change from poor is rigour. Every change is reviewed against its implications for the PHA, the safety integrity level allocation and the fire and explosion assessment, approval comes before implementation, a pre startup safety review comes before commissioning and training comes before operation. Almost every CSB major incident report our team reads carries a management of change failure in the root cause, and Bhopal, Texas City, Flixborough and BP Macondo each trace back to changes that bypassed this discipline.

Management of Change (RBPS Element 13) Overview
Study execution

How the study is executed

A structured, facilitated process that runs from scope definition through close out and produces defensible, actionable outputs.

Change Scope Definition

We define the boundary between a change that is eligible for management of change and a replacement in kind, cover chemical, technology, equipment, procedural and organisational change and align it with CCPS and OSHA guidance.

Review Trigger Matrix

For each change type we specify the mandatory re review of the PHA, the safety integrity level, the fire and explosion assessment, the area classification and the pre startup safety review and integrate it with an electronic system such as SAP, Maximo or Sphera.

Approval Hierarchy

We define the change initiator, the technical reviewer, the area approver and the area authority signoff, align them with the risk tier and specify the authorisation cycle time.

Pre Startup Review Gate

We run the pre startup safety review to OSHA PSM (i), confirming that design and construction match, training is complete, procedures are updated and PHA actions are closed.

Backlog and KPI Discipline

We track the change backlog, set a cycle time KPI, signal close out to engineering and operations and integrate it with corporate HSE governance.

Audit and Continuous Improvement

We run a monthly change quality audit and a root cause review of change failures and integrate the lessons learned from incidents.

Study scope

What the study covers in full

Identification of change across chemical, technology, equipment, procedural and organisational types
Telling replacement in kind apart from change that is eligible for management of change
A trigger to re review the PHA, SIL, fire and explosion and area classification by change type
A pre startup safety review gate before commissioning to OSHA PSM (i)
Training and a procedure update before operation
Management of the change backlog with a full audit trail
Why it matters

Outcomes of Management of Change (RBPS Element 13)

Change Driven Incident Prevention
  • Catches the quiet change patterns that drove Bhopal and Texas City
  • PHA actions travel from worksheet through to verified implementation
  • Safety integrity and fire and explosion implications captured before commissioning
  • The pre startup safety review closes the gap from construction to operation
PSM (l) Change Defence
  • Evidence that withstands an OSHA PSM (l) audit
  • CCPS RBPS Element 13 evidence
  • ISO 45001 Cl.8.1.3 change satisfied
  • The Factories Act 41B procedural requirements met
Change Governance Discipline
  • Less commissioning rework
  • Better close out of PHA actions
  • Sharper depth in engineering review
  • Backlog visible to leadership
Change Programme ROI
  • A major incident from uncontrolled change avoided
  • Less retrofit after startup
  • A strong position with insurers through change quality
  • Engineering productivity through a clear process
