The purpose of this study was to explore the perceptions of off-duty professional firefighters when asked to render emergency care outside of the traditional work setting through crowdsourced technologies. The research focused specifically on the provision of lifesaving interventions to individuals experiencing sudden cardiac arrest in residential settings in metropolitan cities because the availability of public safety resources is typically fixed, and off-duty professional responders may be a viable solution to increase survival rates. The theoretical framework of the study was grounded in the foundational concepts of Pareto optimal/efficient allocation. The research aimed to identify whether leveraging off-duty trained responders could potentially address the issue of resource allocation in public safety. The research followed a qualitative case study methodology, focusing on sudden cardiac death in out-of-hospital settings. Semistructured virtual interviews were conducted with off-duty professional firefighters to understand their perceptions of the topic
