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
