Expanding Critical Controls with Additional Layers

Are warnings, procedures and PPE carrying too much of the load?

The Brady Review found that 62% of the highest-level controls introduced after serious mining accidents were administrative. This brief expands the hierarchy of controls with Inherently Safer Design, Prevention through Design, and Safe and Sustainable by Design, and describes a custom language model built for an oil and gas company to recommend fixes for critical control gaps.

  • Bowtie work with 100+ mining operators and contractors and 300+ subject matter experts to find more effective critical controls.
  • An oil and gas case: a custom language model applied to more than 1,000 incident and critical controls assurance records reached 87.2% accuracy in identifying root causes, and 87% of the controls it generated aligned with subject matter expertise.
