Guide to Technologies for Preventing Serious Injuries and Fatalities Related to Last-minute Work Changes

Unforeseen changes in work site conditions or work operations can be stressful, but especially in last-minute situations when workers are under time constraints. In some instances, the time pressure can lead to distractions, frustration, and poor decisions. In the field, however, a poor safety decision made in response to a last-minute change can result in a serious injury or fatality.

RT-382 found that last-minute changes play a role in the majority of SIF incidents. To respond to this situation, the team explored the idea of using technologies to prevent and/or mitigate the impacts of last-minute work changes that could lead to serious injury or even fatalities.

RT-382 mapped the catalog of technologies to the functional requirements: real-time monitoring, assessing, decision-making, and taking action. The team found that most present systems lack the robust capabilities required. Only two types of technologies could perform all of the functions required to address last-minute changes – AI and site control and site access technologies – but neither is currently ready and trusted. The team concluded that the industry needs to continue its investment in technological development, especially in robotics and AI.
