How iFluids Engineering Delivered a Full-Scope PSM Gap Assessment for CPCL’s Manali Refinery

The Challenge — Benchmarking Process Safety at One of India’s Most Complex Refineries

A PSM gap assessment for an Oil Refinery of CPCL’s scale is not a checkbox exercise. It demands a systematic evaluation of policies, practices, and people across every layer of the safety management system from process safety culture at the leadership level down to asset integrity on the Plant floor. The gap between what exists and what CCPS RBPS requires is rarely obvious until you go looking for it.

CPCL operates under the Ministry of Petroleum and Natural Gas and holds a strong track record on environmental and safety compliance, including adherence to ISO 14001. The Manali facility processes a wide slate of petroleum products viz LPG, Petrol, Diesel, Aviation Turbine Fuel, Kerosene, Bitumen, and Lube base stocks, which means the hazard inventory is substantial and the consequences of process safety failures are severe.

CPCL’s Operational Profile and Safety Mandate

By the time iFluids Engineering was engaged, CPCL had already embedded several layers of safety governance into its operations. The company follows Risk-Based Process Safety (RBPS) practices and maintains active Safety, Health, Environment & Quality (SHEQ) programs. However, a mature safety culture and a fully optimized PSM system are not the same thing. Leadership recognized that distinction and that recognition was the starting point for the engagement.

Why a Structured PSM Gap Assessment Was Non-Negotiable

Refineries operating at CPCL’s level of complexity carry a significant inventory of highly hazardous chemicals. OSHA PSM compliance and alignment with CCPS RBPS guidelines are not just regulatory obligations, rather they are operational imperatives. Without a structured gap analysis, Organizations risk blind spots: elements that appear functional on paper but are inconsistently implemented on the ground. CPCL’s management wanted documented evidence of where their process safety management system performed well and, more importantly, where it did not.

The Methodology — A Structured PSM Gap Analysis Across 20 CCPS RBPS Elements

iFluids Engineering’s PSM gap analysis methodology for CPCL followed a structured, five-stage process: Pre-study data collection, an opening alignment meeting, Plant walkthrough and site study, Personnel interviews and records review, and a final presentation of findings. Every assessment activity mapped directly to one or more of the 20 CCPS RBPS elements.

The engagement was led by a team of Process and Technical Safety Engineers from iFluids Engineering, with site study carried out over several weeks.

Pre-Study Data Collection and Opening Meeting

Before any Site work began, iFluids Engineering issued a formal data request to CPCL covering existing PSM documentation, Safety Procedures, Maintenance Records, Training Logs, And Incident Investigation Reports. The opening meeting aligned both parties on scope, methodology, and the specific CCPS RBPS elements that would be evaluated. This stage is often underestimated, in our experience on similar Refinery engagements, the quality of pre-study documentation directly determines how efficiently the Site phase runs.

Site Walkthrough, Personnel Interviews, and Records Review

The core of the Process Safety Management Audit was conducted on-site. The iFluids team performed detailed Plant walkthroughs, observed work practices in live operating areas, and held structured discussions with Plant Personnel at multiple levels viz Operators, Supervisors, Maintenance Engineers, and EHS Managers. Records were reviewed against each PSM element requirement, including:

• Permit-to-Work (PTW) systems and Lockout/Tagout (LOTO) procedures
• HIRA compliance documentation and PHA records
• Inspection, Testing, and Preventive Maintenance (ITPM) logs
• Training records and competency assessments
• Management of Change (MOC) registers
• Incident investigation and near-miss reporting systems
• Emergency Response and Disaster Management Plans (ERDMP)

Each observation was scored against a standardized rubric, with findings documented as either compliant, opportunity for improvement, or a formal gap requiring corrective action.

The Scoring Framework — From “No System” to “Excellent”

iFluids Engineering applied a four-point scoring scale to every assessment question:

Score	Criteria
0	Poor — No system exists
1	Below Average — Immediate management attention required
2	Average — Requires considerable improvement
3	Good — Needs further strengthening

Element-level scores were then converted to percentage compliance and mapped against a PSM benchmarking scale:

Compliance Range	Rating
0%	Poor
1–25%	Below Average
26–50%	Average
51–70%	Good
71–90%	Very Good
91–100%	Excellent

This framework gave CPCL leadership an unambiguous, defensible baseline, not a subjective narrative, but a scored, traceable compliance profile across all 20 elements.

PSM Gap Assessment Findings — Element-by-Element Results

Across all 20 CCPS RBPS elements assessed at CPCL, the compliance scores ranged well. The majority of elements rated well reflecting a reasonably mature safety management system.

PSM Elements
1	Process Safety Culture
2	Compliance with Standards
3	Process Safety Competency
4	Workforce Involvement
5	Stakeholder Outreach
6	Process Knowledge Management
7	Hazard Identification and Risk Analysis
8	Operating Procedures
9	Safe Work Practices
10	Asset Integrity and Reliability
11	Contractor Management
12	Training and Performance Assurance
13	Management of Change
14	Operational Readiness
15	Conduct of Operations
16	Emergency Management
17	Incident Investigation
18	Measurement and Metrics
19	Auditing
20	Management Review & Continuous Improvement

Strengths Identified Across Key PSM Elements

Emergency Management was the standout performer. CPCL’s Emergency Response and Disaster Management Plan (ERDMP) was well-documented, regularly exercised, and deeply embedded in site operations. Emergency Response Teams (ERTs) were trained and equipped, and mock drill records demonstrated a consistent cadence of preparedness activities.

Auditing and Training and Performance Assurance also scored above the element average. CPCL operates structured Internal Safety Audits (ISAs) and External Safety Audits (ESAs), with findings tracked through a corrective action system. Training programs showed evidence of Training Need Analysis (TNA), competency mapping, and use of a Learning Management System (LMS), a level of maturity that many comparable facilities have not yet reached.

Safe Work Practices reflected a solid Permit-to-Work framework, documented LOTO procedures, and Job Safety Analysis (JSA) practices that were actively used on the plant floor. Workers demonstrated the authority to stop unsafe work, a fundamental indicator of a functioning safety culture.

Several other elements scored well including Asset Integrity and Reliability, Contractor Management, Management of Change, and Operational Readiness.

The iFluids Engineering team delivered a gap analysis report that went beyond scores. Every finding was paired with a specific, actionable recommendation, not generic guidance, but prescriptive corrective actions traceable to the relevant CCPS RBPS standard reference. Priority was explicitly assigned based on risk significance, giving CPCL’s leadership a sequenced action roadmap rather than an undifferentiated list of improvements.

The final deliverable gave CPCL a defensible, scored compliance baseline referenced against CCPS RBPS and international best practices that can be used to track progress in future assessment cycles.

Key Takeaways for Refineries Considering a PSM Gap Assessment

A PSM gap assessment is most valuable when it is treated as a diagnostic tool, not a compliance audit. The goal is not to achieve a passing score rather to understand exactly where your process safety management system is strong, where it is fragile, and what the highest priority actions are to reduce risk.

Three things made this engagement effective:

1. Structured methodology mapped to CCPS RBPS. Evaluating all 20 elements against a consistent scoring rubric rather than picking and choosing ensures no systemic gaps are missed.
2. On-site observation, not just document review. Paper systems and actual practices diverge. Walking the plant, observing PTW execution, and interviewing operators at multiple levels surfaces the real gap, not the documented one.
3. Recommendations linked to standard references. Every finding in the iFluids report cited the relevant CCPS RBPS element, giving CPCL’s team a direct link between the gap and the authoritative guidance for closing it.

If your facility is operating in the 70–80% compliance band on a CCPS RBPS assessment, you are not in a poor position but you are not in a safe one either. That band contains the gaps that cause incidents.
