Understanding Hazards & Risks

Material, process, and facility hazard identification with appropriate risk quantification

Implement this element Back to Responsible Care Process Safety Code

Strategic context

What this element is — and why it matters

Understanding Hazards & Risks is the analytical foundation of Responsible Care — the structured identification and quantification of process hazards across material, process, and facility dimensions. The element integrates chemical safety evaluation (DSC, ARC, dust explosibility), process hazard analysis (HAZOP, LOPA, SIL, QRA, FERA), facility siting per API RP 752/753, and the cumulative-risk mapping that supports corporate ESG and ICCA peer-survey reporting.

Individual significance for organisations

Organisations that invest in deep, defensible hazard understanding catch the patterns that drive major accidents — Bhopal, Texas City, Buncefield, Tianjin all had identified hazards that the organisation chose not to act on. Beyond compliance, mature hazard understanding becomes a competitive asset — informing technology selection, M&A due diligence, insurance dialogue, and capital allocation.

Contribution to Responsible Care Process Safety Code

This element converts Element 1 (Leadership Commitment) into actionable risk knowledge that drives Element 3 (Managing Risk). Outputs feed into Element 4 (Learning from Experience) via baseline risk register, and the discipline established here propagates into Element 5 (Implementation) through PHA quality, SIL allocation rigour, and chemical safety evaluation standards.

Key requirements

What compliant execution looks like

Material hazard characterisation per chemistry — flammability, reactivity, toxicity, dust

Process hazard analysis per IEC 61882 / CCPS Guidelines (HAZOP, LOPA, SIL, QRA)

Facility siting per API RP 752 / 753 / 756 (occupied buildings)

FERA / consequence modelling (PHAST, FLACS) for major accident hazards

Cumulative-risk mapping across portfolio for ICCA peer comparison

Risk register with revalidation triggers and 5-year statutory cycle

Implementation methodology

How we implement this element

A focused 6-step methodology calibrated to deliver understanding hazards & risks as a working capability — not a documented compliance artefact.

Material Hazard Characterisation

Chemical safety evaluation per applicable scenarios — DSC, ARC, dust explosibility (Kst / Pmax / MIE / LOC per NFPA 660), reactivity per CHETAH / Bretherick, toxicity per OECD.

Process Hazard Analysis Programme

IEC 61882 HAZOP at detailed engineering, CCPS LOPA for IPL credit, IEC 61511 SIL allocation, supplemented by FMEA / What-If per process complexity.

Facility Siting & OBRA Studies

API RP 752 occupied building risk assessment, API RP 753 portable buildings, API RP 756 tents — quantify blast, thermal, toxic exposure of personnel buildings to credible-worst-case scenarios.

Consequence Modelling

PHAST / FLACS / DEGADIS / SAFETI modelling for VCE, BLEVE, pool fire, jet fire, toxic dispersion; align with EPA RMP / Seveso credible-worst-case definition.

Cumulative Risk Mapping

Portfolio-level risk aggregation — IRPA, F-N curves, site PLL; integrate with corporate ESG risk register and ICCA peer-survey reporting.

Risk Register & Revalidation

Maintain live risk register with MOC-triggered partial revalidation + 5-year statutory cycle; align with API RP 754 PSE indicator framework.

Deliverables

What we produce

Material hazard characterisation database
PHA / HAZOP / LOPA / SIL workbooks per process
Facility siting study (API RP 752 / 753 / 756)
FERA consequence modelling outputs

Common pitfalls

Where execution fails

PHA quality compromised by missing operator perspective
FERA modelling done with outdated PSI inputs
Facility siting studies skipped for older brownfield sites
Risk register not connected to ICCA / API RP 754 reporting
