1
Workplace Ergonomics
2
What is Ergonomics?
  • The word ERGO means work
  • NOMICS Means Rules or Laws
  • Ergonomics literally means
  • The laws of work

3
SO WHAT ISERGONOMICS EXACTLY?
  • It is study of people efficiency at their
    working environment.
  • It is one of the definition of Ergonomics.
  • It is understandable that there are different
    definitions because ergonomics is all about
    differences

4
DIFFERENCES
  • This are differences in size, shape, strength and
    ability of individual workers.
  • This differences call for different designs in
    equipment , furniture,
  • Workstations and routines.

5
ERGONOMICS
  • Ergonomics is used in a workplace to help prevent
    repetitive and cumulative injuries.

6
3 Main Ergonomic Principles
  • Work activities should permit worker to adopt
    several different healthy and safe postures.
  • Muscle forces should be done by the largest
    appropriate muscle groups available
  • Work activities s/b performed with joints at
    about mid-point of their ROM (esp. head, trunk,
    UE)

7
FACTS
  • The average person working at a keyboard can
    perform 50,000 to 200,000 keystrokes a day
  • Overexertion falls are the most common cause
    of workplace injury
  • An average of 125,000 back injuries due to
    improper lifting each year.
  • Muscles overuse results in tiny tears in the
    muscles and scarring these contribute to
    inflammation and muscle stiffness

8
Ergonomic Factors
  • Two Categories of Ergonomic Factors
  • 1. Environmental
  • Hearing
  • Vision
  • General comfort and health
  • 2. Physical

9
Environmental Factors
  • Some examples of ergonomic environmental problems
    are
  • Sick Building Syndrome
  • Excessive noise
  • Improper lighting
  • Temperature extremes

10
Physical Stressors
  • Physical stressors place pressure or stress on
    parts of the body
  • Joints, muscles, nerves, tendons, bones
  • Sometimes these injuries are referred to as
    Cumulative Trauma Disorders (CTDs) or
    Repetitive Strain Injuries (RSIs)

11
Types of Injuries
  • Muscle pain
  • Joint pain
  • Swelling
  • Numbness
  • Restricted motion
  • Repetitive stress injury
  • Repetitive motion injury
  • Cumulative trauma disorder
  • Musculoskeletal disorder

12
ERGONOMIC STRESS AREAS
Hip
Knee
13
Target Regions
  • Back
  • Upper extremities
  • Lower extremities

14
Types of Problems or Mismatches
  • Physical Size
  • Endurance
  • Strength
  • Manipulative
  • Environmental
  • Cognitive

15
Physical Size
  • Clearance
  • Reach
  • Equipment Size
  • Personal Protective Equipment (PPE)

16
Cognitive
  • Machine Pacing
  • Shift Work
  • Morale
  • Psychosocial

17
Musculoskeletal DisordersSigns and Symptoms
  • Decreased grip and/or pinch strength
  • Swelling
  • Fatigue
  • Loss of function
  • Numbness
  • Burning sensation
  • Tingling
  • Pain
  • Cramping
  • Stiffness

18
An ounce of Prevention is worth a pound of cure !
19
What to do ??
  • Warm up stretch before activities that are
    repetitive, static or prolonged
  • Take frequent breaks from ANY sustained posture
    every 20-30 minutes
  • Respect pain positions or stop painful activity
  • Recognize early signs of inflammatory process

20
Posture checkIncreased stress, decreased
circulation
21
PostureThink of posture in terms of joint
position
  • Static and awkward postures lead to
  • Decreased movement
  • Decreased circulation
  • Increased stress and fatigue

22
Maintain Neutral Posture
  • Maintain erect position of back neck without
    shoulders relaxed
  • Position equipment work directly in front of
    and close to your major tasks
  • Avoid static positions for prolonged time
    muscles fatigue---MOVE to circulation!

23
Modify Tasks
  • Alternate activities frequently rotate heavy
    /or repetitive tasks without lighter less
    repetitive ones.
  • If stress become worse REASSESS task setup look
    for alternative methods
  • Avoid repetitive or prolonged grip activities

24
Computer workstation ergonomics
  • Chair
  • Monitor
  • Keyboard
  • Mouse
  • Document holders
  • Lumbar pads/pillows
  • Arm rests
  • Glare
  • Eye strain
  • Footrests
  • Wrists pads
  • Keyboard trays
  • Laptops
