Practical articles on process safety and engineering for the teams who run high hazard facilities.
HAZID Studies and the Guidewords That Drive Them
A working reference for hazard identification studies, covering where HAZID belongs in the lifecycle, the full guideword register with team prompts, what the worksheet must record, and when a finding has to leave HAZID for another technique.
Read articleISO 14064 Carbon Accounting in Practice
How an industrial GHG inventory is actually built under ISO 14064, where the categories differ from the scopes you already report, and why a reported reduction can happen without anything changing at the plant.
Read articleProcess Safety Management, a Working Reference
The OSHA and CCPS element sets compared, what each element has to produce as evidence, the applicability thresholds, and the API RP 754 indicator arithmetic with a calculator.
Read articleSIL Verification and the Proof Test Interval Nobody Rechecks
The PFD arithmetic behind a SIL rating, why the proof test interval and its coverage usually dominate the answer, and what architectural constraints do that the equations cannot.
Read articleCombustible Dust, Kst, and Why Secondary Explosions Do the Killing
The cubic law, what Kst and MIE actually tell you, and the layer thickness arithmetic that decides whether housekeeping is tidiness or a life safety control.
Read articleReading a QRA, Individual Risk, F N Curves and What Moves the Answer
The arithmetic behind individual risk and societal risk, the inputs that swing the result by an order of magnitude, and how to review a study you did not write.
Read articleThe Leak Frequencies Decide Your QRA Before Any Modelling
Release frequency enters the risk result linearly, comes from generic databases that disagree with each other, and is usually the least examined number in the study. What the sources are, why they differ, and how to adjust them to your asset.
Read articleIgnition Probability, the Number With the Widest Range
Whether a flammable release disperses or explodes turns on a single probability, the correlations behind it disagree, and congestion decides whether you get a flash fire or a blast. What the models assume and how to defend the value you used.
Read articleReactive Relief Sizing, a Working Guide to DIERS Methods
Why single phase methods understate the area a runaway needs, with Leung's equation, the omega method, phi correction and a worked case.
Read article10 Common HAZOP Mistakes and How to Avoid Them
A practical look at the recurring errors that weaken hazard and operability studies and the habits that keep them rigorous.
Read articleA Practical Pressure Relief Design Checklist
A working checklist for engineers sizing and specifying pressure relief systems so nothing critical slips through.
Read articleWhat Every Plant Manager Should Know About Process Safety
A clear overview of the process safety fundamentals that let a plant manager ask the right questions and see trouble early.
Read articleUnderstanding SIL and LOPA in Plain Terms
A jargon free explanation of safety integrity levels and layer of protection analysis and how the two fit together.
Read articleWhat is HAZOP? A Plain Guide to the Hazard and Operability Study
A clear explanation of the hazard and operability study, how the guide word method works and when a plant should run one.
Read articleWhat is LOPA? Layer of Protection Analysis Explained
A plain explanation of layer of protection analysis, how it credits independent safeguards and how it sets a risk reduction target.
Read articleWhat is Quantitative Risk Assessment (QRA)?
An explanation of quantitative risk assessment, how it turns hazards into numerical risk and where the results are used.
Read articleWhat is FERA? Fire and Explosion Risk Analysis Explained
An explanation of fire and explosion risk analysis, how it models thermal and blast effects and how it informs layout and protection.
Read articleWhat is Functional Safety? SIL and IEC 61511 Explained
An explanation of functional safety, what a safety integrity level means and how the safety lifecycle keeps protection reliable.
Read articleWhat is a Process Safety Management System?
An explanation of a process safety management system, the elements it contains and how they work together to prevent major incidents.
Read articleWhat is Bow Tie Analysis? Barrier Based Risk Made Visual
A clear introduction to bow tie analysis, the diagram that turns a major hazard into a picture of the barriers that keep it under control.
Read articleWhat is a Dust Hazard Analysis? Combustible Dust Explained
An introduction to the dust hazard analysis and why fine powders that seem harmless can fuel a devastating explosion.
Read articleWhat is Inherent Safer Design?
An explanation of inherent safer design, the philosophy of removing hazards at the source rather than controlling them later.
Read articleWhat is Operational Excellence in Process Manufacturing?
An introduction to operational excellence and how process plants pursue reliable, efficient and safe operation as a discipline.
Read articleWhat is Life Cycle Assessment (LCA)?
An introduction to life cycle assessment, the method for measuring the environmental impact of a product across its whole life.
Read articleUnknown Chemistry, Hidden Cost. Why Chemical, Pharma and API Plants Must Characterise Their Reaction Hazards
In fine chemical, pharmaceutical and API work the chemistry is often new and poorly characterised, and the hazards that no one has measured are the ones a standard study cannot catch.
