HAZOP analysis of human factors in combine harvesters
IOP Conference Series: Materials Science and Engineering, 2018 In recent years, agricultural machinery accidents have remained high, and in addition to the reasons for the lack of machinery itself, human factors account for a large proportion. This paper mainly introduces some accident classification and operation specifications of harvesters, divides the operation specifications into nodes, and then uses the ...

A systematic approach for identifying drivers of critical safety and establishing their hierarchy
The Canadian Journal of Chemical Engineering, Volume 103, Issue 10, Page 4628-4646, October 2025.Abstract Learning from incidents is a crucial step in preventing and mitigating adverse events. Incident databases offer valuable insights for safety management improvements by cause and contributing factors. However, extracting meaningful information from incident investigation reports poses a significant challenge. This study introduces a data‐driven

Process Safety Progress, Volume 44, Issue 3, Page 379-393, September 2025.Abstract Qualitative risk assessments, such as hazard and operability studies (HAZOP), are critical for identifying hazards and implementing risk mitigation strategies in industrial processes. One key yet often overlooked measure of HAZOP quality is the completeness of safeguard identification, which can serve as a practical key result indicator (KRI).

Safety Monitoring of Machine Learning Perception Functions: A Survey
Computational Intelligence, Volume 41, Issue 2, April 2025.ABSTRACT Machine Learning (ML) models, such as deep neural networks, are widely applied in autonomous systems to perform complex perception tasks. New dependability challenges arise when ML predictions are used in safety‐critical applications, like autonomous cars and surgical robots. Thus, the use of fault tolerance mechanisms, such as safety monitors,
