Ergonomics and human factors
Design for human capabilities and limits.
In depth
Ergonomics designs tasks, tools and environments to fit human capabilities: anthropometry, posture (RULA/REBA), force limits (NIOSH lifting equation), repetition, vibration, noise, lighting, cognitive load and interface design. Reduces injury, error and fatigue, and improves productivity.
Key points
- Percentile design (5th–95th)
- Workstation layout
- Human error taxonomy
ExampleAdjustable workstations reduce musculoskeletal disorders in assembly work.
What is Ergonomics and human factors?
Design for human capabilities and limits.
Why is it important to understand ergonomics and human factors?
Ergonomics designs equipment and work for human capabilities, which reduces injuries, errors and fatigue.
What is ergonomics?
The study of how people interact with systems and how to design work, tools and environments to fit human body size, strength and cognition.
Why is it important for safety?
Poor design encourages errors and injuries, so good ergonomics reduces accidents and improves quality.
How is Ergonomics and human factors used in practice?
Typical applications include setting the height of a workbench for an operator who stands all day, designing a control panel so the most used buttons are easy to reach and reducing the lifting load on a packaging line to prevent back injuries.
What should I learn before Ergonomics and human factors?
Study "Fault tree analysis" first (topic 44 of 102 in Manufacturing, Robotics & Systems). It covers the groundwork this topic builds on.
What are the key points of Ergonomics and human factors?
Percentile design (5th–95th). Workstation layout. Human error taxonomy.
Can you give an example of Ergonomics and human factors?
Adjustable workstations reduce musculoskeletal disorders in assembly work.
What comes after Ergonomics and human factors?
The next topic is "Industrial safety", which builds directly on this one.
How difficult is Ergonomics and human factors?
It is classed as Intermediate in Manufacturing, Robotics & Systems (topic 45 of 102). It is an intermediate topic. Work through the beginner topics in Manufacturing, Robotics & Systems first.
