Ergonomics Awareness Training for Construction Workers
A workshop for workers and supervisors in identifying and solving ergonomic problems on construction sites
Training Agenda & ObjectivesTraining Agenda & Objectives
Hardhat Ergonomics-PowerPoint Presentation 1.2 (November 2000) Slide 2
1. Introducing Ergonomics •define Ergonomics
2. Musculoskeletal Disorders Where does your job hurt you?
•identify Musculoskeletal Disorders common to construction workers that are caused by ergonomic hazards
3. Ergonomic Job Analysis How does your job hurt you? How can the job be changed?
•discuss the problems (Ergonomic Risk Factors) that cause these disorders
•practice an Ergonomic Job Analysis (EJA) to identify and reduce Ergonomic Risk Factors
4. “Best Arguments” How can you make ergonomic job redesign happen?
•discuss ways to successfully implement ergonomic solutions on-the-job
5. Evaluation What do you think?
•evaluate this training

“Experience is the best teacher.”
Introduce yourself to the people at your table.
Add up how many years your group has worked in the construction industry.
Report your group’s total number of years worked to the large group.

Use your brain, not your back.
Work smarter, not harder.
Fix the job, not the worker.
Ergonomics is…
the science and the art of
fitting the job and the workplace
to workers’ needs.

Where does your body hurt after working on
the construction site all day?
Mark the places that people in your group hurt after working on the construction site on your group’s BODY MAP.

Hardhat Ergonomics-PowerPoint Presentation 1.2 (November 2000) Slide 7
Post your group’s BODY MAP on the wall.
Compare the BODY MAPS.
What seems to be the same about the BODY MAPS?
What do the BODY MAPS tell us about construction work?

A study done by the University of Iowa has shown that construction workers hurt!
• 70% report pain in their lower back
• 46% report pain in their knees
• 43% report pain in their wrists and hands
• 42% report pain in their shoulders and necks (The University of Iowa Construction Survey, 1996)

MUSCULOSKELETAL DISORDERS
or
MSDs
Also called:
• Cumulative trauma disorders (CTDs)
• Repetitive strain injuries (RSIs)

3 Facts about MUSCULOSKELETAL DISORDERS
1) They affect your musculoskeletal system - your muscles, nerves, tendons, ligaments, joints, cartilage
and spinal discs.
2) They are cumulative - they happen gradually, as opposed to accidents.
3) They are chronic - the effects last a long time.

Hardhat Ergonomics-PowerPoint Presentation 1.2 (November 2000) Slide 11
In your group, brainstorm a list of MSDs that your know of, or that you have had.
Choose one MSD that your group has talked about to discuss with the class.
Tell us how you got it.

MSDs are the longest lasting injuries:
They damage workers’ health more than any other type of injury in construction.
MSDs are the most costly injuries:
They cause greater financial damage than any other type of injury in construction
Over 40% of worker compensation costs in construction are due to MSDs.

The RISK FACTORS for MSDs are:
• Force • Vibration
• Repetition • Extreme temperatures
• Awkward Postures • Work stress
• Static postures

Doing an EJA: Step 1
With your group, choose a construction job or task that you think needs to be changed.
Complete Part 1 of the Ergonomic Job Analysis(EJA) on the first page of the EJA Handout:
Quickly draw the job -- Include the tools, the equipment, and the workers.

Doing an EJA: Step 2
Turn to the next page of the EJA Handout and work together to complete Part 2 - the Risk Factor Checklist:
Check off all the ergonomic risk factors that are part of the job.

ergonomic risk factors?
