Learning objectives
Learning Objectives

At the conclusion of this training you will be able to:

  • Explain ergonomic principles

  • Identify risks involved with working

    Additionally you will :

  • Understand how the use of good ergonomic principles keep you safe


Applications of ergonomics
Applications of Ergonomics


Why is ergonomics challenging
Why is Ergonomics Challenging?

People are different



Anatomy1
Anatomy

Tendons


Muscles and joints
Muscles and Joints

  • Need rest to recover

  • Need good circulation

  • Maintain strength



Risk factors
Risk Factors

  • Repetitive Motions

  • Forceful Exertions

  • Awkward Posture

  • Contact Stress

  • Vibration


Repetitive motions
Repetitive Motions

  • No Rest for muscles and joints

  • Inflammation of tendons, nerves & joints

  • Loss of strength (Muscle fatigue)

  • Decreased circulation

  • Body position


Forceful exertions
Forceful Exertions

  • Inflammation of tendons, nerves & joints

  • Poor grip (gloves, handles)

  • Loss of circulation

  • Loss of strength (Muscle fatigue)


Awkward posture
Awkward Posture

  • Poor circulation

  • Arms above heart

  • Extended reach

  • Holding a fix position (static)

  • Twisting or bending


Contact stress
Contact Stress

  • Loss of circulation

  • Inflammation to tendons, nerves & joints


Vibration
Vibration

  • Poor circulation

  • Inflammation of tendons, nerves & joints


Manufacturing ergonomics
Manufacturing Ergonomics

Risks:

  • Twisting or extending reach

  • Overhead Work (Circulation)

  • Repetition without rest

  • Standing Static (Circulation)

  • “Burping cases” (Palm as Hammer)

  • Resting on sharp edges (Circulation)

  • Number of task movements


Manufacturing ergonomics1
Manufacturing Ergonomics

Injury Prevention:

  • Warm up muscles, joints

  • Neutral Position

  • Rotate muscle groups

  • Do not rest on sharp edges

  • Good grip

  • Switch feet positions

  • Take micro breaks


Office ergonomics
Office Ergonomics

Risks:

  • Poor posture (tilted head, hunched)

  • Poor lighting

  • Long reach

  • Poor chair position

  • Poor monitor position

  • Resting on sharp edges


Office ergonomics1
Office Ergonomics

Injury Prevention:

  • Neutral Position

  • Arms close to body

  • Knees bent at 90o, feet flat while sitting

  • Monitor at correct height

  • Rest wrists while typing

  • Take breaks and stretch


Ergonomics team
Ergonomics Team

  • Evaluate each task

  • Reduce the number of movements

  • Provide Feedback

  • Provide Ideas

  • Feasibility


If signs of injury exist
If Signs of Injury Exist

  • Inform Supervisor immediately

  • Complete an injury report

  • Rest specific body part

  • Ice

  • Early intervention is the key
