See hazards before they become incidents—then reduce risk in a deliberate, defensible way.
HIRA (Hazard Identification & Risk Assessment) is a structured approach to finding what can go wrong and evaluating the risk so you can decide what to do about it. In process industries, HIRA looks across people, equipment, procedures, and the surrounding environment to anticipate scenarios such as loss of containment, overpressure, ignition, toxic exposure, and utility failures—throughout the asset lifecycle from design to decommissioning.
Define Scope & Criteria
Set boundaries (processes/units/activities), stakeholders, and risk criteria (consequence categories, tolerability targets, ALARP expectations).
Gather Process Knowledge
Compile Process Safety Information and operations inputs: P&IDs, PFDs, causes & effects, MSDS/SDS, layouts, relief/flare data, DCS/SIS narratives, permits, incidents, and changes (MOC).
Identify Hazards & Scenarios
Use multiple lenses to avoid blind spots: energy sources, chemistry & reactivity, containment integrity, human factors, maintenance/contractor interfaces, SIMOPS, utilities, external events (flood/fire/seismic), and environment/community impact.
Analyze Risk
Estimate likelihood and consequence using your agreed risk matrix. Where useful, apply bow tie thinking to map threats → barriers → consequences, and use LOPA to check if independent protection layers are sufficient.
Evaluate & Decide
Compare residual risk to criteria; determine if additional controls are required. Apply the hierarchy of controls (eliminate → substitute → engineer → admin → PPE) and align with functional safety needs for SIF/SIL where applicable.
Action Planning
Convert findings into a risk-ranked action register with owners, due dates, and verification methods. Separate quick wins from foundational fixes (e.g., design changes, MI strategy, alarm rationalization).
Document, Communicate, and Verify
Issue a concise report, hazard register, and barrier summary. Brief leaders and frontline teams, embed actions in existing systems (e.g., MOC, CMMS, action tracker), and define metrics to monitor barrier health.
Maintain & Refresh
Revisit HIRA at set intervals and upon triggers: process changes, incidents, new projects/startups, turnarounds, and organizational changes.
Typical HIRA tools we facilitate: HAZID workshops, task-based risk assessments/JSA, What-If/Checklist reviews, Bow Ties, LOPA screening, and barrier/critical control reviews.
Whether you need a targeted HAZID, a site-wide HIRA, or an independent barrier review, we’ll help you see the whole risk picture and act where it counts most. Let’s discuss your scope and goals.
