Human Factors ‘Drills Down’ to the Root Causes Behind Incidents

Research within the oil and gas sector frequently highlights how problems such as process and procedure non-compliance, lack of safety culture adherence and breakdowns in safety critical communications can remain unresolved over long periods of time. This is historically due to corrective measures focusing on out-dated concepts of technical error and human fallibility, instead of addressing the overarching root cause of the problem (Gordon, 1998; Sanders, 1987; Wickens, 2004).

Human factors (HF) allows for a holistic approach to non-technical error. Our expertise highlights operator behaviours and limitations such as stress and strain, fatigue, cognitive load, communications, distractions, attention focus, situation awareness and other critical variables required to maintain operational safety. Addressing these previously disregarded factors allows for a user-centred approach when re-designing processes and procedures to consider the capabilities and limitations of the human tasked with following the instructions (Endsley, 1995; Hancock & Parasuraman, 2002; HSE, 2012).

Clear communication is critical

To take the example of communications: IHF reviews safety-critical communications frequently – highlighting instructions which are difficult and confusing to follow, do not represent a logical order, are located over multiple documents, out-dated and do not clearly reflect the current operational standards for ‘doing things’ (Thomas & Carroll, 1981; Reason, 1995).

Deconstructing and rebuilding procedures

Rebuilding procedures from the perspective of the end-user allows for human factors to be taken into account. Information can be ordered in a manner which accurately represents the task steps within the procedure, dangers and hazards can be highlighted as initial, critical information and instructions can be worded, presented and broken down in a manner which will not ‘overload’ the end-user (HSE, Shackel, B, 1991; HSE, 2012).


While this is a brief example discussing just a few human factors components and applications, it serves to highlight the necessity of the field as a tool to manage operational safety, human-error and accident/near miss occurrence. A human factors approach should be taken no less seriously than the physical integrity of workplace tools and equipment.
