Overview
ISO/TR 23932-2:2020 - Fire safety engineering - General principles - Part 2: Example of a dry‑cleaning store is a technical report that provides a complete, worked example illustrating how to apply the FSE (fire safety engineering) process described in ISO 23932-1. The document uses a small dry‑cleaning shop case study (life‑safety objective for occupants and neighbours) to walk through scope definition, objective setting, hazard identification, scenario development, analysis, design proposals and operational controls. Although an FSE study is usually unnecessary for such a small shop, the example was chosen to demonstrate ISO 23932-1 in a concise, practical way.
Key topics and technical requirements
The report covers the practical steps of an FSE process and highlights these technical topics:
- Scope and objective setting for a fire safety engineering project (defining life‑safety as the primary objective).
- Identification of fire safety objectives and functional requirements, including occupant protection, neighbour protection, firefighter safety and property protection.
- Selection of risk analysis approach and identification of performance criteria for each objective.
- Fire safety design plan development: proposed solutions, management of fire safety and a documented design proposal.
- Fire and behavioural scenarios: hazard identification, development of fire scenarios and human behaviour modelling.
- Selection of engineering methods and scenario‑based evaluation: quantification of design fire scenarios and comparison with performance criteria.
- Operating and maintenance conditions: defining conditions of use and control frequency for the built environment.
The report also includes technical appendices such as plans, material descriptions and environmental context to support scenario development.
Practical applications
ISO/TR 23932-2:2020 is practical for:
- Illustrating how to turn ISO 23932-1 principles into a documented FSE study.
- Training and education for fire safety engineers, consultants and building designers.
- Providing a template/example for developing fire safety design plans, scenario analyses, and performance‑based assessments in small commercial premises (especially shops handling hazardous cleaning fluids).
- Supporting stakeholders in demonstrating compliance with life‑safety objectives when applying performance‑based fire safety solutions.
Who should use this standard
- Fire safety engineers and consultants
- Building designers and architects
- Safety managers for commercial premises (e.g., dry‑cleaners)
- Regulators and building control authorities
- Educators and students in fire protection engineering
