1 Scope
This document compiles a collection of different probes/gauges for assessing common
playground equipment safety performance to eliminate known safety hazards such as:
entrapment and entanglement hazards on playground, playspaces, and associated equipment
used in different countries/regions around the world. It also explains some historical
content of origins, the purpose and some rationales for the dimensions and shape of
each of those probes.
NOTE These test probes and gauges, their dimensions and related historic rationale for their existence are of significant value to playground equipment, manufacturers, designers, installers, assemblers, owners, operators and inspectors alike and are necessary tools to the reduction of serious, life-threatening and debilitating injuries to the public playground intended users.
