Safety and quality metrics for process hazard analysis
Process Safety Progress, 2020AbstractCompanies use metrics to monitor their process safety performance. Process safety metrics may relate to any aspect of a process safety program but many metrics are developed for individual process safety elements, such as process hazard analysis (PHA).

Employing process simulation for hazardous process deviation identification and analysis
Safety Science, 2018Abstract To improve industrial safety, several hazard analyses of processes are available. The HAZOP is one of the most frequently employed and analyzes hazardous process deviations based on heuristic knowledge. Despite the wide application of the technique, new developments are especially important to enhance industrial safety.

Reliability Analysis for Hazardous Waste Treatment Processes
Risk Analysis, 1999The reliability of a treatment process is addressed in terms of achieving a regulatory effluent concentration standard and the design safety factors associated with the treatment process. This methodology was then appliedto two aqueous hazardous waste treatment processes: packed tower aeration and activated sludge (aerobic) biological treatment.

On the validation of safeguards for process hazards analysis
Process Safety Progress, 2013An article presented at the 8th Global Congress on process safety addressed the need to validate the adequacy of safeguards in order for them to be credited in process hazard analysis (PHA). Validation of safeguards is critical for process safety but its inclusion within PHA would cause a serious distraction from identifying hazard scenarios, which is ...

Integrating job safety analysis into process hazard analysis
Process Safety Progress, 2010Abstract In this article, the author will present and explain in some detail how the job safety analysis (JSA) technique can be integrated into and used in conjunction with any of the six process hazard analysis (PHA) techniques required by the Occupational Safety and Health Administration process safety management Standard for highly

Treatment of multiple failures in process hazard analysis
Process Safety Progress, 2013Process hazard analysis (PHA) is used to identify hazard scenarios. These hazard scenarios may be initiated by single or multiple failures. Other scenario events, such as the responses of safeguards, are also subject to multiple failure, and enabling events may combine with initiating events or other scenario events to produce a type of multiple ...

Guidelines for Process Hazards Analysis (PHA, HAZOP), Hazards Identification, and Risk Analysis
2003This unique manual is a comprehensive, easy-to-read overview of hazards analysis as it applies to the process and allied industries. The book begins by building a background in the technical definition of risk, past industrial incidents and their impacts, ensuing legislation, and the language and terms of the risk field.

A hybrid strategy for batch process hazards analysis
Computers & Chemical Engineering, 2000Abstract In this paper we present a framework that addresses the three main parts of a process hazards analysis (PHA) study — hazard identification, hazard evaluation, and hazard mitigation. The framework utilizes a hybrid methodology that effectively combines a qualitative digraph model-based technique for performing hazard identification and a ...

Preliminary Hazard Analysis on Fire and Explosion Hazard of Stevedoring Process in LNG Terminal
Applied Mechanics and Materials, 2014Through the introduction to stevedoring process of LNG terminal, the preliminary hazard analysis technique is applied to distinguish and identify three potential dangerous factors which could cause fire and explosion, and corresponding preliminary hazard lists are then established respectively.

Prework and precompletion of worksheets for process hazard analysis
Process Safety Progress, 2012AbstractPrework in preparation for process hazard analysis (PHA) is vital for an efficient study. Precompletion of PHA worksheets in an effort to reduce the time needed for a PHA study may detract from the quality of the study and also may not be acceptable to regulators.
