Process safety engineers increasingly work across two regulatory worlds at once: a US practice built around OSHA Process Safety Management and EPA Risk Management Program requirements, and a European practice shaped by the Seveso III Directive. The underlying engineering discipline, identifying hazards, assessing risk, and verifying safeguards, is the same in both places. What differs is the vocabulary, the documentation expectations, and the unit system, and a practitioner without a reference built for that specific gap ends up re-deriving conversions, re-learning terminology, or assuming one framework works like the other.

This handbook addresses that gap directly, working through hazard evaluation as it actually unfolds in practice: identification, risk assessment, safeguard evaluation, and facilitation, using the same five-question hierarchy throughout: what can go wrong, how bad could it be, how often might it happen, is the resulting risk acceptable, and what more can reasonably be done.

Across twenty chapters you can explore and apply:

Checklist, What-If, HAZOP, and FMEA hazard identification, including HAZOP's full guide-word system and FMEA's severity-occurrence-detection rating scales, plus a documented framework for choosing among them

Calibrated risk matrices and hand calculations for toxic and flammable dispersion, pool fires, vapor cloud explosions, and BLEVEs

Fault tree and event tree analysis down to minimal cut sets and quantified event probabilities

Layer of Protection Analysis, including the four independent-protection-layer qualification criteria, and full quantitative risk assessment with individual and societal risk measures

Safety instrumented system architecture and SIL verification across 1oo1, 1oo2, 2oo2, and 2oo3 voting, inherently safer design, and human reliability analysis

Auditing an existing, previously credited safeguard inventory to determine whether it still performs at the level a study originally assumed

A dedicated engineering-calculation and unit-conversion reference, since every numeric value throughout appears in both US customary and SI units

Every chapter follows the same fixed structure: learning objectives, a full worked example, a Mistake Autopsy built around one specific plausible failure and the rule that prevents it, a Field Capstone, and practice problems with a verified answer key, so you can check your own calculations against a shown solution. Three composite case studies close the handbook, tracing a HAZOP node-boundary gap, an IPL independence failure, and a human-reliability shortfall back to the specific chapters that address each one, and a consolidated glossary and topic index support quick reference use.

This handbook is written for process safety engineers, PHA facilitators, chemical and plant engineering leads, and EHS professionals working across US and European facilities, clients, or corporate structures, in chemical manufacturing and adjacent process industries such as refining, oil and gas, pharmaceuticals, and bulk materials handling, along with engineering students building a working command of the discipline. Open the chapter you need, work the calculations in the units your project actually uses, and build a hazard evaluation practice that holds up under review on either side of the Atlantic.
