Saferparks was an organization that collected data on ride safety via public records requests. They were last active in 2017, accordingly their data set is outdated. It can still be used to identify trends in the industry and serves as an archive of many US amusement ride incidents from ~2000 - 2017.

This data is hosted by RidesDatabase and can be downloaded here: https://ridesdatabase.org/saferparks/data/

CARES (Council of Amusement and Recreational Equipment Safety) is an organization that focused on ride maintenance and inspections within the US and Canada. They have now scaled back operations. CARES collected and archived many ride service bulletins, creating a great online database for this information where owners and operators can easily access them.

ASTM: The ASTM F24 committee has produced several standards related to amusement ride safety. The committee meets about twice a year to write and revise these standards.* These standards are technicality voluntary, but are mandatory in many areas.

F2291: Standard Practice for Design of Amusement Rides and Devices.

F3559: Standard Guide for ASTM F24 Standards Governing Lifecycle Management of Amusement Rides and Devices

F2376: Standard Practice for Classification, Design, Manufacture, Construction, and Operation of Water Slide Systems

ISO Standards: These standards are often referenced in ASTM standards and are generally more broad. One of the most applicable to amusement rides is ISO 12100:2010: Safety of machinery — General principles for design — Risk assessment and risk reduction

Purchase of these standards directly support the sessions where they are developed and refined by amusement engineers, industry leaders, and subject matter experts who share the common goal of amusement safety.**

IAAPA is the Global Association for the Attractions Industry. They have lots of resources for those in the industry or interested in the industry. They also have several resources for ride safety, including an annual report: https://iaapa.org/safety-security/ride-safety-report
