Objectives • Introduction to Ergonomics • Overview of Ergonomic Risk Factors • Basic Ergonomic Design Principles • How to Arrange Your Workspace
Ergonomics • The science of adjusting and arranging the environment to fit the employee. • Visual and musculoskeletal discomfort and fatigue are eliminated or reduced.
Risk Factors • Repetition • A task or a series of motions performed over and over • Forceful Exertions • Amount of physical effort required to perform a task • Awkward Postures • Reaching, bending, twisting, holding fixed positions • Contact Stress • Exposure of a body part to a hard or sharp surface repetitively or forcefully at a workstation or tool
Eliminate Repetition • Take frequent, short breaks • Drink water • Vary tasks throughout your day
Eliminate Forceful Exertions • Keyboard strokes • Pushing and pulling
Eliminate Awkward Postures • Telephone • Document References • Chair • Keyboard • Mouse • Visual Display Unit • Desk
Eliminate Contact Stress • Desk • Chair • Mouse • Keyboard
The Chair • Seat Pan • Provides support, waterfall design, adequate hip room. • Height • Adjustable? Feet firmly on the ground. • Lumbar Support • Back Rest • Large enough to provide mid to upper support. • Armrests • Adjustable, padded and contoured. • 5 Spokes for Stability
Keyboard Placement and Positioning • Just above the user’s lap – 1”- 2” above the thighs • Lettered portion of the keyboard centered with the visual display unit • The letter “H” should be aligned with the user’s bellybutton • At a negative slope
Mouse Placement and Positioning • Mouse from the elbow • Eliminate the numeric keypad • At a negative slope • Avoid wrist wrests
The Desk • Consider the user(s) • 28” – 30” above the floor • Deep enough to accommodate all equipment and processing information • Make it adjustable, if possible • Rolled edges
The Visual Display Unit (VDU) • Eliminate glare • Arm’s length away or more • Centered in front of the user (duel VDU exemption) • Bottom of the VDU tilted towards the user • VDU should be as low as possible, 15 – 50 degrees below horizontal eye level
Lighting • Indirect lighting • Control outside lighting with blinds and shades • Keep ambient light levels low and supplement with task lighting • Position the VDT so that it is parallel with the fluorescent tube
