Principles of ergonomics

Principles of Ergonomics


Principle 1

Principle 1

Work in Neutral Postures


Maintain the s curve of the spine

Maintain the “S-Curve” of the Spine


The neck

The Neck


Keep elbows in and shoulders relaxed

Keep Elbows in and Shoulders Relaxed


Keep wrists in neutral

Keep Wrists in Neutral


Summary neutral postures

Summary — Neutral Postures

Neck straight

Shoulders relaxed

Elbows at sides

Wrists in neutral

Back with S-curve


Point

Point:

  • To work smarter, work in neutral postures

  • Evaluate and modify:

    • work method

    • tools

    • workstation design


Principle 2

Principle 2

Reduce Excessive Force


Point1

Point:

  • Think of what you do.

  • Think of ways to reduce excessive force.

  • Thousands of ways, only some examples here.


Principle 3

Principle 3

Keep Everything in Easy Reach

Principle 4

Principle 4

Work at Proper Heights


Height elbow drawing

Height elbow drawing

Most work at

elbow height

(sitting or standing)

Height elbow hi/lo drawing

Exceptions:

Heavy = lower

Precision = higher

Cumulative trauma disorders ctds

Cumulative Trauma Disorders (CTDs)

“Wear and tear” that accumulates thru time


Symptoms

Symptoms

  • Soreness, pain, discomfort

  • Numbness or burning

  • “Pins and needles”

  • Limited range of motion

  • Weakness and clumsiness


Basic message to everyone

Basic Message to Everyone:

If you think you may have a problem

Get it checked out


Risk factors for ctds
