Ergonomics
Making the job
fit the worker
Ergonomics looks at:
• Work station
• Tools
• Motions
• Physical
condition
• Physical limitations
• Environment
1
Musculoskeletal disorders
• Musculoskeletal disorders = MSDs
2a
MSD symptoms
• Dull, aching sensation
• Discomfort with movements
• Tenderness to the touch
• Burning sensation
• Pain
• Tingling
• Cramping
• Stiffness
2b
Common MSDs
• Tendinitis
• Tenosynovitis
• Trigger finger
• Raynaud’s syndrome
• De Quervain’s disease
• Carpal tunnel syndrome
2c
Workplace risk factors
• Repetitive motions
• Fixed / awkward postures
• Vibration
• Force
• Twisting / bending
• Elevation of elbows
• Lifting
3a
Workplace risk factors
• Inappropriate tools
• Continuous contact
• Restricted clearance
• Improper seating/
support
• Bad body mechanics
• Inadjustable equipment
3b
Identify risk factors
• Management/employee involvement
• Audit work
stations
• Audit
procedures
4a
Engineering controls
• Preferred method
• Work station
design
• Tool design
• Equipment design
5a
Work station design
Provide adequate:
• Work space
• Work height
• Support
• Storage space
• Machine controls
6a
Work station design
• Reduce static loading
• Raise / lower working height
• Remove hard / sharp edges
• Provide mechanical
advantages
• Insulate heat / cold
7a
Work station redesign
• Provide seating / support
• Improve material
orientation
• Improve layout
7b
Tool selection should
minimize:
• Awkward, bent grip
• Vibration
• Excessive grip strength
• Awkward
positions to
exert force
• Repetitive
motions
8a
Administrative controls
• Job rotation
• Shift length
• Overtime management
• Rest breaks
• Production
rates
9a
Work practice controls
• Use proper techniques
• Avoid
unnecessary steps
• Job training
• Exercise/
conditioning
10a
Medical management
• Early reporting & treatment
• Symptoms survey
• Medical treatment
• Recordkeeping
11a
Back disorders
• Sprains
• Strains
• Ruptured/
slipped disks
• Muscle spasms
12a
Back pain factors
• Improper posture
• Poor physical
condition
• Improper
lifting
12b
Proper lifting
• Size up the load
• Bend your knees
• Do not twist
• Clear path
• Lower slowly
• Push carts/dollies
12c
Summary
• Define ergonomics
• MSDs
• Risk factors
• Controls
• Medical management
• Proper lifting
