Human Factors - The "Dirty Dozen" (PowerPoint PPTX)

"We don't redesign humans; We redesign the system within which humans work"
Various industries including aviation sector have realized the need of understating in human factors and utilization and application of the understanding in order to protect human and properties and enhance productivities through maximizing efficiency in workplace

Industry has made great progress managing process related hazards and preventive strategies to protect workers, property, and environment

Focus on managing process major hazards through the design and incorporation of more complex equipment and systems

Non-process related major hazards are well understood but receive less focus than the process hazards during design and fabrication

Challenges of industry continue and require multi-disciplinary and cross functional collaboration internal/external to the organizations even when manpower and resources are stretched

Accidents continue to happen and the majority can be linked to a human error or inadequate human performance

Industry needs to raise the bar using predictive analytic data to improve human performance, reduce risk, limit liability, sustain productivity, and meet regulatory obligations

Due to a large number of maintenance-related aviation accidents and incidents that occurred in the late 1980s and early 1990s, Transport Canada identified twelve human factors that degrade people's ability to perform effectively and safely, which could lead to maintenance errors. These twelve factors, known as the "dirty dozen," were eventually adopted by the aviation industry as a straight forward means to discuss human error in maintenance. It is important to know the dirty dozen, how to recognize their symptoms, and most importantly, know how to avoid or contain errors produced by the dirty dozen. Understanding the interaction between organizational, work group, and individual factors that may lead to errors and accidents, Aviation Maintenance Technicians can learn to prevent or manage them proactively in the future.

For each element on The Dirty Dozen we can list typical countermeasures designed to reduce the possibility of any human error from causing or developing into a problem, accident or incident.
The 92-slides PowerPoint document gives you an effective overview of Human Factors Theory and explains with relevant examples the twelve most known human factors the "Dirty Dozen" and their respective safety Nets.
