NRSPP - Rio Tinto's Critical Control Verification Program

The Safety Loop – CRM Program, Bow Ties and Preventing Fatalities And Serious Injuries

How a linked CRM-bow tie approach can prevent fatalities and serious injuries

In 2018 the National Road Safety Partnership Program (NRSPP) published a case study featuring the outcomes and successes of Rio Tinto’s implementation of a layered critical control verification program.

Key excerpts from the case study:

  • More than 1.4 million critical control verifications were done in 2017 across Rio Tinto’s global network
  • At Rio Tinto, control verification includes daily physical checks in the field by 6,500 frontline operational leaders
  • Before a job goes ahead, operators verify that the critical control is in place by answering a series of yes/no questions, on a task-by-task basis
  • Supervisors also verify those critical controls are in place, on a shift-by-shift basis
  • Managers or superintendents routinely verify the design and implementation of the controls
  • This ‘cascade effect’ reinforces a strong safety culture and expectations within the organization
  • Checks are recorded in a centralized global database, highlighting any non-compliances so any potential weak areas are identified and can be rectified
  • The level of safety awareness and of critical controls at the frontline has significantly improved as has the targeted focus on measures needed to prevent fatalities and serious injuries
