Synopsis

Keywords: Safety, Safety

Motivation: MR safety guidance formulated by experts from the MR community build upon a combination of experience and technical expertise. MR safety guidance may benefit from assessment based on general workplace safety practices.

Goal(s): To critically assess MR safety guidance and practices using the hierarchy of hazard controls.

Approach: MR safety practices were scored using a 5-point scale derived from the hierarchy of hazard controls, in several areas of risk for MR personnel, patients, and non-MR personnel.

Results: Hazard controls for non-MR personnel had consistently high effectiveness scores, while those for for MR personnel and patients had moderate effectiveness scores, with a greater range.

Impact: The analysis presented in this work could serve as a tool to analyse choices made in the deployment of safety measures, to motivate decision- or policy-making, or as a tool for assessment of MR safety programs.
