ASTM WK92058
Revision of F2291-24 Standard Practice for Design of Amusement Rides and Devices
Rationale
The purpose of this ballot is to clarify the existing requirement to conduct an analysis to determine the opening between the walkway and the track. It is recognized that when the usage of these walkways is exclusively by workers performing preventative maintenance work, that the opening may be acceptable at 12 inches (304mm) in its least dimension. However, if the walkway is a patron accessible area, such as a load/unload platform or evacuation area, this opening must be reduced.
In this ballot, patron areas prescribe a new opening listed at 4 inches in its least dimension or a designer may perform an analysis that results in a slightly different number. The 4” sphere for the opening is used because it has been used previously in fencing to protect children from hazards. However, this language allows for the analysis to determine a number between 4” and 12” if so desired.
It is not the intent of this section to require narrow openings around all elements of amusement rides, but to have the designer of this fall protection system be aware of the increased risk involved of smaller patrons when around those fall hazards and include mitigations in the design.
