Human Factors & Culture

Human factors and culture plays crucial roles in process safety and creating an organization’s safety culture. Safety culture is defined as how the organization behaves when no one is watching. The responsibility for fostering and sustaining a sound safety culture cascades down through an organization/company.

The UK Experience In Managing Risks Arising From Human Error

Mar 13, 2011
David Embrey
Following the Piper Alpha incident in the North Sea, both offshore and onshore Oil and Gas operators in the UK were required under the COMAH (Control of Major Accident Hazards) regulations to submit a Safety Case setting out how the risks in their installations were to be managed. After many years...

Human Performance Training

Mar 13, 2011
Don D. Nguyen
Operator competency has been a major challenge for the petrochemical and refining industry for decades. In recent times, human factors are believed to be a consistent contributing cause for a lot of incidents. Current schemes used to determine an operator's competency are subjective and somewhat...

Near-Miss Management to Develop Dynamic Leading Indicators to Predict Incidents

Mar 23, 2010
Ankur Pariyani
Recent studies have shown the importance of identifying near-misses to predict the probability of accidents (Meel and Seider, 2006) – and managing them to reduce the potential of accidents (Phimister et al., 2003; Cooke and Rohleder, 2006). In this paper, new methodologies involving near-miss...

A Framework for Human Error Analysis of Emergency Situations

Mar 23, 2010
Travis JB Deacon
Human factors play an important role in the escape, evacuation and rescue process. Human factors analysis is rooted in the concept that the frequency and consequences of human errors are related to work environment, work culture and procedures. This can be accounted for in the design of equipment,...

Modular Procedural Automation Addressing the Post Recession Skills Gap

Mar 23, 2010
Maurice J. Wilkins
A procedural operation consists of a set of tasks that are conducted in a set way time-after-time to achieve a certain goal such as starting or shutting down a unit or making a product. As demonstrated by Paul McKenzie (Bristol Myers Squibb) at the WBF NA Conference 2007 in Baltimore, it could even...

Elements of Human Factors Missing from Process Safety

Mar 23, 2010
Revonda Tew
Process safety is about controlling risk of failures and errors; controlling risk is primarily about reducing the risk of human error. All elements of Risk-Based Process Safety (RBPS) and alternative standards for process safety (such as US OSHA's standard for Process Safety Management [PSM] or ACC...

Evaluating Human Response to an Alarm for LOPA or Safety Studies

Mar 23, 2010
Robert J. Stack
Many LOPA scenarios have an independent protection layer (IPL) credit for operator intervention to prevent or mitigate the scenario. It is often difficult for the LOPA team or other safety teams to assess if the appropriate operator response credit is being taken. To allow a more consistent...

An Integrated Toolkit for Addressing Human Factors Issues in Process Safety

Mar 23, 2010
David Embrey
This paper describes an integrated toolset, called the Human Factors Workbench, which addresses the proactive and reactive control of human error in process operations. It is a practical application of the tools described in the CCPS publication: ‘Guidelines for Preventing Human Error in Process...

How to Evaluate Process Safety Culture

Mar 22, 2010
Jerry Forest
At first glance it may seem that organizational culture is subjective and therefore difficult to measure. Indeed, even the definition of culture falls into the soft side of process safety. This paper will show that an objective approach can be taken to survey and define process safety culture. With...

LOPA and Human Reliability – Human Errors and Human IPLs

Mar 21, 2010
Bill Bridges
Layer of Protection Analysis (LOPA) is a simplified risk assessment method that provides an order of magnitude estimate of the risk of a potential accident scenario. Humans can be the cause on an accident scenario (the Initiating Event [IE]) or human can serve as an independent protection layer (...
