2
Goals


Musculoskeletal disorders (MSD)
Quiz
3
What Is Ergonomics?


Science of fitting jobs to
the people who do them
Goal is to reduce workrelated MSD when their jobs
require repetitive
reaching, bending, lifting,
using force, working with
vibrating equipment, and
doing other repetitive
motions
4
What Are MSDs?
Injury to:
 Muscles
 Nerves
 Tendons
 Ligaments
 Joints
 Spinal discs
5
Common MSDs









Carpal tunnel syndrome
Tendonitis
Trigger finger
Raynaud’s syndrome
De Quervain’s disease
Rotator cuff tendonitis
Carpet layers’ knee
Herniated spinal disc
Low back pain
6
Signs of MSDs




Less strength for gripping
Less range of motion
Loss of muscle function
Inability to do everyday tasks
7
Common Symptoms of MSDs






Painful joints such as wrists, shoulders,
forearms, knees
Pain, tingling, numbness in hands or feet
Shooting pain in arms or legs
Swelling, inflammation, burning sensation
Fingers or toes turning white
Back or neck pain or stiffness
8
Report all Signs or
Symptoms of MSDs



Permanent disability may result if not
reported early
Report signs or symptoms of MSDs to your
supervisor, Safety Program Manager,
Human Resources representative or
Worker’s Compensation Insurance Claims
Clerk.
Report MSD hazards
9
Repetition





Same motion over and
over puts stress on
muscles and tendons
How often the
movement is repeated
Speed of the movement
Number of muscles
involved
Required force
10
Forceful Exertions






Amount of physical effort
required to perform a task
Effort needed to control
equipment or tools
Type of grip
Weight of object
Body posture
Type and duration
of the task
11
Awkward Postures







Reaching
Twisting
Bending
Kneeling
Squatting
Working overhead
Holding fixed
positions
12
Contact Stress




Pressing your body
against a hard or sharp
edge
Puts pressure on nerves,
tendons, and blood
vessels
Allowing your wrists to
rest on the keyboard
when typing
Holding tools with
hard handles
13
Vibration






Sanders
Grinders
Chippers
Routers
Drills
Saws
14
Goals


Musculoskeletal disorders (MSD)
Quiz
15
Response to MSD Report


Employer performs a job hazard analysis of
your job for MSD hazards
Employer takes steps to reduce MSD
hazards
16
MSD Incident



Requires medical treatment beyond
first-aid
MSD signs or symptoms that last seven
or more consecutive days
Treat the same as any other workplace
injury.
17
MSD Management



Employee provided
with access to a health
care professional
Evaluation and
follow-up of
MSD incident
Temporary work
restriction may be
necessary
18
Job Hazard Analysis




Determine whether MSD
hazards exist
Employee should be
involved in identification
of MSD hazards
Implement control
measures to reduce
the hazards
Train employees and
supervisors
in the affected jobs
19
Goals


Musculoskeletal disorders (MSD)
Quiz
20
Summary




Recognize MSD signs and symptoms
Understand MSD hazards
Learn to take steps to control MSD hazards
Report MSDs the same as any other
workplace injury
21
