Full title and description

St IEC 61882-2016 — "Hazard and operability studies (HAZOP studies) - Application guide". This international standard provides guidance on performing HAZOP studies using the standard set of guide words, and covers procedure, preparation, examination sessions, documentation and follow-up, together with examples and case studies.

Abstract

IEC 61882:2016 (Edition 2) is an application guide for HAZOP (Hazard and Operability) studies. It updates and replaces the first edition published in 2001, clarifying terminology (aligned with ISO 31000 and ISO Guide 73) and adding improved case-study material including procedural HAZOP examples. The publication is intended as a practical reference for teams carrying out systematic HAZOP risk assessments.

Scope

Provides a practical application guide for conducting HAZOP studies on systems using the defined set of guide words. The standard gives guidance on HAZOP definition and objectives, study team roles, preparation and documentation, conduct of examination sessions, analysis and follow-up of recommendations, and includes documentation examples and a broad set of illustrative case studies across different applications. This second edition is a technical revision of the 2001 edition.

Key topics and requirements

• Overview of HAZOP methodology and terminology (aligned with ISO 31000/ISO Guide 73).
• Guide words and their systematic application to identify deviations from design/intended operation.
• Study procedure: scope definition, team composition, roles and responsibilities, preparation and documentation practices.
• Execution of examination sessions: node selection, prompt questions, deviation analysis and cause/consequence evaluation.
• Recording findings, recommending risk-reduction measures, and follow-up/closure processes.
• Worked examples and case studies (including procedural HAZOP use-cases) to illustrate application in different industries.

Typical use and users

Used by process safety engineers, HSE/risk assessment professionals, design and operations teams, consultants and regulators involved in chemical, petrochemical, pharmaceutical, utilities, power generation, oil & gas and other process industries. Typical use-cases include design reviews, major modifications, start-up and commissioning reviews, and periodic safety assessments where systematic identification of hazards and operability issues is required.

Related standards

Related documents and standards commonly referenced alongside IEC 61882 include ISO 31000 (risk management principles and guidelines), ISO Guide 73 (vocabulary for risk management), industry-specific process safety and functional safety standards (for example process safety management frameworks and functional safety standards), and the previous edition IEC 61882:2001 which this edition replaces. Users often apply IEC 61882 together with organizational safety management and technical standards relevant to their sector.
