New Practice for Risk Assessment for Amusement Rides and Devices

1. Scope

This practice establishes requirements and guidance for designer/engineers, manufacturers and owner/operators on conducting or contributing to risk assessment for amusement rides and devices by specifying basic terminology, principles and methodology. Risk assessment as discussed in this practice refers to the risk assessment process, including risk reduction, as described in Section 5.

This practice is applicable to all amusement rides and devices under the jurisdiction of ASTM Committee F24.

This practice is limited to risk of harm to persons resulting from interaction with amusement rides and devices.

This practice is applicable to risks associated with the operation and use of amusement rides and devices including their external interfaces. The operation and use phase begins once the amusement ride or device is first placed into service and ends once it is permanently taken out of service. This phase includes all uses of the amusement ride or device, such as operation, evacuation, and maintenance activities. This phase also includes routine assembly/disassembly/transportation of portable amusement rides and devices. This practice does not address hazards for other lifecycle phases such as manufacturing, construction, installation, commissioning and de-commissioning.

ASTM Committee F24 is a collection of the best standards in the amusement industry. However, due to the importance of risk assessment it was recognized that the F24 suite of standards could be improved by developing a standard to specifically address the topic of Risk Assessment for the amusement industry. In 2018 a task group was formed to draft an industry specific Risk Assessment standard.
This new standard will follow the general intent of other industry accepted Risk Assessment standards, specifically, ISO12100 and ANSI B11.0. The task group recognized that these standards are more general and there was still a need for a F24 industry-specific standard.
This effort intends to harmonize with other international amusement industry standards, such as EN13814, ISO17842, etc., and expand the topic of risk assessment by clearly defining the process from a holistic viewpoint.
Following are the cornerstones of this proposed standard practice:
1) Scope – This is a standalone standard to be used by all F24 members regardless of their role in the industry or the type of ride/device they are working with.
2) Scalability/Applicability – This standard is written to be scalable, meaning it can be applied to a small modification as well as the initial development of a multi-year, multi-phase highly integrated system with many different participants. This standard is applicable to all amusement rides and devices under the jurisdiction of Committee F24.
3) Supplemental Requirements – This standard is written to supplement other ASTM standards that call for a Ride Analysis, such as Section 5 in F2291. This standard will not replace that language.

The title and scope are in draft form and are under development within this ASTM Committee.
