Process Hazard Analysis (PHA)
Structured HAZOP, HAZID, What-If and checklist studies, facilitated and documented to identify hazardous scenarios and evaluate safeguards.
Services
Process safety services
Twelve integrated service lines covering the full process safety lifecycle — from identifying hazards to verifying that safeguards work and programs are sustained.
Hazard & Risk Analysis
Identify hazards and evaluate risk
LOPA & Risk Assessment
Layer of Protection Analysis, bowtie analysis and risk ranking to determine whether safeguards provide enough risk reduction.
Consequence Analysis, QRA & Facility Siting
Release, fire, explosion and toxic consequence modeling, quantitative risk assessment and building siting evaluations.
Combustible Dust & Reactive Chemical Hazards
Dust hazard analyses and chemical reactivity hazard reviews, including interpretation of laboratory test data.
Programs & Compliance
Build and sustain compliant programs
Process Safety Management (PSM)
Development, gap assessment and improvement of PSM programs covering all 14 elements of OSHA 29 CFR 1910.119.
EPA Risk Management Program (RMP)
RMP applicability, hazard assessments, prevention and emergency response programs, and plan updates under 40 CFR Part 68.
Mechanical Integrity
Mechanical integrity program design and assessment: equipment lists, inspection and test planning, procedures and deficiency management.
Audits & Incident Investigation
PSM/RMP compliance audits, program effectiveness reviews and structured incident and near-miss investigations.
Engineering & Capability
Engineer and verify safeguards; build capability
Functional Safety & Safety Instrumented Systems
Safety lifecycle support under IEC 61511 / ISA 61511: SIL targeting, SRS development, SIL verification, proof testing, alarms and F&G.
Pressure Relief System Engineering
Relief scenario identification, device sizing and verification, inlet and outlet hydraulics, and flare and vent system evaluation.
Engineering & Implementation Support
Process safety information, PHA recommendation resolution, MOC and PSSR support, and project process safety reviews.
Process Safety Training
Practical courses for operators, engineers and managers: PSM fundamentals, PHA participation and leadership, LOPA, MOC and PSSR.
How the services connect
One study's output is the next study's input
Process safety work is most effective when it is consistent from one activity to the next. These are the hand-offs we manage most often.
| From | Produces | Feeds into |
|---|---|---|
| PHA / HAZOP | Scenarios, safeguards, risk ranking, recommendations | LOPA, relief review, procedures, training, MI priorities |
| LOPA | Required risk reduction, IPL register | SIL targets, mechanical integrity and test programs |
| SIS lifecycle | SRS, verification, proof test procedures | MI program, operating procedures, MOC |
| Relief engineering | Relief design basis, flare loads | PSI, PHA, LOPA credit, MI testing |
| Consequence analysis | Effect distances, risk contours | PHA severity ranking, RMP, siting, emergency planning |
| Audits & investigations | Findings, root causes | Program improvement, PHA revalidation, training |
