Abstract
Human error can cause severe problems in industrial oil, gas, and chemical processes.
Although human factors analysis and classification systems (HFACSs) for
the oil and gas industry (HFACS-OGI) and the small-scale chemical industry
(HFACS-CSMEs) have been independently developed, there are s
ome limitations
in providing detailed information on the contributing factors. Therefore, a new
HFACS must be developed that can be commonly applied to the oil, gas, and
chemical fields. This paper develops an integrated HFACS that can be applied to
the oil, gas, chemical, and power plants, called HFACS-OGAPI, by analyzing
45 accidents that occurred in domestic and overseas oil, gas, chemical, and power
plants, based on the HFACS-OGI system. An integrated HFACS-OGAPI that can
be applied to the oil, gas, chemical, and power plants is developed. The framework
effectively identifies the contributing factors by providing specific information
on Tiers 1, 2, 3, and 4 for Levels 1, 2, 3, 4, and 5. The contributing factors are
effectively identified by analyzing the BP Texas Refinery explosion (2005), the
Kleen Energy natural gas explosion (2010), and the Aghorn Operating Waterflood
Station accidents (2019) with the developed framework. A checklist suitable for
the HFACS-OGAPI is developed by considering the contents developed by the
National Aeronautics and Space Administration and the Department of Defense
to determine the contributing factors. The developed checklist is expected to
effectively identify and improve on the causes of human error through periodic
inspection.
