Bow Tie Risk Analysis and Barrier Management

A bow tie shows a hazard, the event that releases it, and every barrier standing between the two, which makes it the one risk method a workforce can read without training and the reason it has spread across major hazard industry. This course covers building them properly. Delegates work through hazard and top event definition, which is where most bow ties go wrong by starting with a consequence, threats and the barriers that prevent each, and consequences with the barriers that mitigate. Barrier quality is covered honestly: whether a barrier is effective, independent and auditable, since a diagram full of weak barriers looks reassuring. Escalation factors and their controls follow. The course closes on using bow ties operationally, and on the barrier owner who must maintain each one.

Course objectives

  • Define a hazard and top event correctly rather than starting from consequence
  • Identify threats and the preventive barriers against each
  • Identify consequences and the mitigating barriers
  • Assess whether a barrier is effective, independent and auditable
  • Identify escalation factors and the controls that address them
  • Assign barrier ownership and maintenance responsibility
  • Use bow ties operationally rather than as a one off study

Who should attend

  • Process safety and HSE practitioners
  • Operations and maintenance supervisors on major hazard sites
  • Risk managers and analysts
  • Engineers participating in hazard studies
  • Regulators reviewing barrier based safety arguments
