Integrating human factors into process hazard analysis
Reliability Engineering & System Safety, 2007A comprehensive process hazard analysis (PHA) needs to address human factors. This paper describes an approach that systematically identifies human error in process design and the human factors that influence its production and propagation. It is deductive in nature and therefore considers human error as a top event.

Metrics and analytics for process hazard analysis
Journal of Loss Prevention in the Process Industries, 2020Abstract Process hazard analysis (PHA) studies (e.g. HAZOP) identify hazard scenarios and each scenario is examined individually to decide whether risk reduction measures are needed. However, much more can be done to benefit from the contents of studies.

Major hazards analysis: An improved method for process hazard analysis
Process Safety Progress, 2003AbstractProcess hazard analyses (PHAs) usually focus on major hazards—fires, explosions, and toxic releases. Traditional PHA methods, such as the Hazard and Operability (HAZOP) study and What‐If analysis, often include scenarios for other hazard types, such as operability problems. Sometimes, this may be desired, but not always.

Process hazard analysis of the selected process in intermodal transport
International Conference on Military Technologies (ICMT) 2015, 2015Process hazard analysis of the selected handling process at an intermodal terminal was performed in the article. The basics of the reliability of such an analysis were presented. The causal groups of situations, which may lead to undesirable situations, were selected.

Process hazard analysis quality
Process Safety Progress, 2009Abstract In this article, the author will discuss the elements that go into a high quality process hazard analysis (PHA). Specific suggestions for performing a high quality PHA will be presented and discussed. The author will show that it is possible to adhere faithfully to the legal requirements in performing a PHA and still produce ...

Hazard Analysis for the Evaluation of the Hazard Potential of Chemical Process Units
Chemical Engineering & Technology, 2002Hazard analysis based on many years of practical experience accrued by safety engineers at the former Hoechst corporation is an excellent tool for assessing potential dangers emanating in particular from chemical processing plants. The assessment of plant failures by this procedure permits a relating weighting of their safety engineering relevance ...

Cognitive biases in process hazard analysis
Journal of Loss Prevention in the Process Industries, 2016Abstract Many decisions are made by process hazard analysis (PHA) teams in identifying hazard scenarios and determining if there is a need to reduce the risk of catastrophic accidents. Observations of PHA teams conducting studies indicated that such decisions are not always made rationally.
