Risk Based Process Safety (RBPS)

CCPS RBPS deployment — calibrating safety effort to risk, not box-ticking

What this system delivers

Risk Based Process
Safety (RBPS)

Risk Based Process Safety, codified by the CCPS in 2007 and refined through more than a decade of major-accident learning (Texas City, Buncefield, Jaipur, Bhopal revisitations), is the prevailing global PSM architecture. It restructures 14 OSHA elements into 20 RBPS elements organised under four pillars — Commit to Process Safety, Understand Hazards and Risk, Manage Risk, and Learn from Experience — and explicitly scales effort against process-safety risk. Mature RBPS deployments shift resourcing toward the high-consequence end of the inventory, eliminate the compliance plateau that traps PSM 1.0 organisations, and produce a defensible API RP 754 Tier 1–4 metric set for the board and regulator.

System implementation

How the system is implemented

A structured, facilitated process — from scope definition through close-out — producing defensible, actionable outputs.

RBPS Maturity Diagnostic & Risk-Effort Baseline

Conduct 20-element maturity diagnostic calibrated on the CCPS 1–5 scale with cross-functional site team; map current state by pillar (Commit / Understand / Manage / Learn); establish risk-effort calibration comparing current PSM resource allocation against the facility's credible MAH inventory.

PSI Architecture & Data Foundation

Audit Process Safety Information for accuracy and completeness across P&IDs, as-built documentation, equipment datasheets, MAWP, and chemical data; design the PSI single-source-of-truth architecture — document control, GIS, CMMS, and engineering data — and clear the MOC backlog.

PHA / HAZOP Revalidation Programme Design

Establish the 5-year statutory PHA/HAZOP revalidation cycle with event-driven and MOC-triggered supplementary reviews; define study scope, node prioritisation, and action close-out tracking against OSHA 1910.119(e) and CCPS guidelines; integrate HAZOP findings into LOPA and Bow-Tie workflows.

MOC, PSSR & Procedure Integration

Implement Management of Change procedure with temporary, permanent, and organisational-change classifications; deploy PSSR checklist library covering mechanical, instrumentation, ATEX, and process pre-requisites; build operating procedure architecture (normal / startup / shutdown / emergency / abnormal) per OSHA (f).

API RP 754 KPI Framework & Culture Diagnostic

Specify Tier 1–4 PSE leading and lagging indicators including demand rate, near-miss frequency, safeguard impairment, and audit findings; design board-grade dashboard; administer CCPS culture survey or Hudson process safety culture ladder assessment to baseline leadership and workforce safety culture.

Governance Roadmap, Audit Cycle & Vision 20/20

Assign element-level accountable executives with RACI; build quarterly assurance cycle and annual self-audit programme; issue 3-year RBPS roadmap with element milestones, capex envelope, and Vision 20/20 alignment: committed culture, vibrant management systems, disciplined adherence, and intentional competency.

PHA/HAZOP revalidation cycle design (5-year statutory, event-driven, MOC-triggered)
MOC, PSSR, and operating procedure integration with engineering and digital workflows
API RP 754 Tier 1–4 leading and lagging indicator framework with board-grade reporting
Process safety competency model and culture diagnostic (Hudson, CCPS culture survey)
Element-level governance: accountable executives, RACI, and quarterly assurance cycle
Audit and FSA programme — first, second, and third-party scrutiny readiness
Vision 20/20 alignment: committed culture, vibrant management systems, disciplined adherence, intentional competency
Why it matters

Outcomes of Risk Based Process Safety (RBPS)

MAH Risk Reduction
  • Reduces Tier 1 PSE frequency demonstrably across multi-year baselines
  • Concentrates safeguards and verification on the dominant MAH contributors
  • Disrupts incident precursor chains identified through Tier 3/4 leading indicators
  • Closes systemic gaps surfaced by Bhopal-era and Texas-City-era learning
CCPS RBPS / OSHA PSM Defence
  • Aligns OSHA PSM, EPA RMP, and Seveso III obligations under one operating model
  • Provides API RP 754-aligned evidence for regulators, insurers, and lenders
  • Withstands HSE / OSHA NEP / PCB inspection without programme rebuild
  • Anchors second-party assurance for joint-venture and tolling partners
MOC, PSI & Procedure Discipline
  • Cuts MOC throughput time without reducing rigour
  • Eliminates duplicate PSI repositories — one engineering source of truth
  • Drives operator competency to demonstrable, role-based standards
  • Accelerates incident learning loop from event to action close-out
Proactive PSM Investment Value
  • Defers reactive PSM spend — funding flows to the credible MAH set
  • Reduces underwriter loadings via demonstrable RBPS maturity progression
  • Avoids OSHA / RMP / Seveso enforcement actions (per-violation cost compounding)
  • Protects production guarantees, debt covenants, and licence-to-operate
