Overview
ISO/TR 24666:2023 - Sports and recreational facilities - Probes for entrapment/entanglement on playground equipment - Collection of data - is a technical report that compiles and explains the variety of probes and gauges used internationally to assess entrapment and entanglement hazards on playgrounds. The document documents the origins, purpose and rationale for the shapes and dimensions of those test probes and provides an international inventory of test methods and probe/gauge figures. It is the second edition (2023), updating and expanding the 2022 edition.
Key topics and technical content
- Scope and purpose: Collection of different probes/gauges for identifying known safety hazards (head/neck entrapment, finger entrapment, impalement, entanglement, crush and shear, etc.) and the historical rationale for probe dimensions and shapes.
- Anthropometrics and user scoping: Discussion of referenced anthropometric datasets and age/size groupings used in regional standards (for example, ASTM F1487, ASTM F2373, EN 1176, AS 4685, CSA Z614, JPFA, SS 457, MS 966). The report explains how age groups (toddlers, preschool, school-age) influence probe selection and tests.
- International inventory: A consolidated list of probes/gauges and associated test procedures from different countries/regions, including figures and tables for practical use.
- Hazard-specific annexes: Informative annexes (A–I) that address specific hazard types such as completely bounded head entrapment, partially bounded openings, protrusion/impalement, suspended-component impalement, crush/shear, finger entrapment, entanglement, and hazard tests for toddlers.
- Normative reference: Cross-references ISO/TR 20183 for injury/safety definitions and thresholds.
Practical applications and users
ISO/TR 24666:2023 is a practical reference and toolkit for:
- Playground equipment manufacturers and designers - to evaluate product geometries against recognized probe tests during design and product development.
- Installers, assemblers and owners/operators - to verify installed equipment does not present entrapment/entanglement hazards.
- Inspectors and safety auditors - as a harmonized source of probe types and test procedures for routine inspections and compliance checks.
- Standards bodies and regulators - to compare regional practices and inform national standards or guidance.
- Risk assessors and safety consultants - to identify, communicate and mitigate life‑threatening hazards to intended users (toddlers to school-age children).
