Employers Responsibility…..
Responsible for providing a safe and healthful workplace for their employees.
Ergonomic principals need to be applied to reduce the musculoskeletal disorders resulting from physical overexertion and associated costs.
![Page 4: ILRI Ergonomics Training](https://reader033.vdocuments.net/reader033/viewer/2022061221/54beb02b4a7959705b8b475e/html5/thumbnails/4.jpg)
What is Ergonomics?
This involves fitting the job to the worker and not the worker to the job. This helps to lessen muscle fatigue, increases productivity and reduces the number of severity of work related musculoskeletal disorders (MSDs)
The science of adapting workstations, tools, equipment and job practices to be compatible with employees.
![Page 5: ILRI Ergonomics Training](https://reader033.vdocuments.net/reader033/viewer/2022061221/54beb02b4a7959705b8b475e/html5/thumbnails/5.jpg)
Why Ergonomics?
To reduce the risk of;
• Accidents• Injury • Ill health that are brought about by poor
ergonomics
Reduce Sickness Absence / Costs Increase Performance / OutputEveryone in your organization is at risk and it is not
just “heavy” or “physical” jobs that cause injury
![Page 6: ILRI Ergonomics Training](https://reader033.vdocuments.net/reader033/viewer/2022061221/54beb02b4a7959705b8b475e/html5/thumbnails/6.jpg)
Assessments……
•By assessing all aspects of:
• Individuals and the jobs they perform e.g. Their physical capabilities, tasks, equipment ,tools and working environment.
•To design work systems that are safe, flexible, efficient and productive.
![Page 7: ILRI Ergonomics Training](https://reader033.vdocuments.net/reader033/viewer/2022061221/54beb02b4a7959705b8b475e/html5/thumbnails/7.jpg)
Examples of Musculoskeletal Disorders- MSDs
Musculoskeletal Disorders affect the muscles, nerves and tendons. The disorders are:
• Carpal Tunnel Syndrome• Tendinitis• Rotator cuff injuries (a shoulder problem)• Epicondylitis (an elbow problem)• Muscle strains and low back injuries
![Page 8: ILRI Ergonomics Training](https://reader033.vdocuments.net/reader033/viewer/2022061221/54beb02b4a7959705b8b475e/html5/thumbnails/8.jpg)
![Page 9: ILRI Ergonomics Training](https://reader033.vdocuments.net/reader033/viewer/2022061221/54beb02b4a7959705b8b475e/html5/thumbnails/9.jpg)
Health Issues Associated with Poor Ergonomics
Pain/Back Injuries
Work related upper limb disorder
Psychological problems (Stress)
![Page 10: ILRI Ergonomics Training](https://reader033.vdocuments.net/reader033/viewer/2022061221/54beb02b4a7959705b8b475e/html5/thumbnails/10.jpg)
Back Pain & Injuries
Bending, Twisting, and Lifting
• Incorrect Posture
• Prolonged Sitting and/or Standing
• Slips Trips & Fall
• Exposure to Vibration
![Page 11: ILRI Ergonomics Training](https://reader033.vdocuments.net/reader033/viewer/2022061221/54beb02b4a7959705b8b475e/html5/thumbnails/11.jpg)
Work Related Upper Limb Disorders
Can affect:– Fingers– Hands– Wrists– Arms– Shoulders– Neck
continued “over use” can lead to permanent damage through:
Repetitive actions/pacing machinesFrequent applications of forceUnnatural postures/positionsInadequate R & R (rest and recovery)Inadequate physical preparation (warming up)
![Page 12: ILRI Ergonomics Training](https://reader033.vdocuments.net/reader033/viewer/2022061221/54beb02b4a7959705b8b475e/html5/thumbnails/12.jpg)
Psychological Factors
This is a very complex area
A person under too much “pressure” may be more at risk from;
– Physical / Ergonomic Injury – Fatigue– Accidents [mistakes, inattention, saving time, shortcut’s]– General ill health [run down / poor condition]– Substance Abuse
![Page 13: ILRI Ergonomics Training](https://reader033.vdocuments.net/reader033/viewer/2022061221/54beb02b4a7959705b8b475e/html5/thumbnails/13.jpg)
The Worker &Ergonomics
Two Basic Objectives; Match the requirements of a task to the individual
Optimise the design of the task to the individual to reduce the risk of injury, ill health and discomfort.
E.g.: Work stations may need to be adjustable so that they suit a range of people.
![Page 14: ILRI Ergonomics Training](https://reader033.vdocuments.net/reader033/viewer/2022061221/54beb02b4a7959705b8b475e/html5/thumbnails/14.jpg)
The Worker
Each worker is unique:
• Size & Shape• Age and Gender• Race and Language• Physical Ability [Health & Fitness]• Limitations [Vulnerabilities, Disabilities, Mental Ability]• Experience
•It is very difficult to optimise a task or a workplace to suit everyone
![Page 15: ILRI Ergonomics Training](https://reader033.vdocuments.net/reader033/viewer/2022061221/54beb02b4a7959705b8b475e/html5/thumbnails/15.jpg)
People and Comfort….
different views about
• Temperature• Ventilation• Lighting• Background Noise• Isolation• Overcrowding• Communication
Discomfort will influence how a person will work
![Page 16: ILRI Ergonomics Training](https://reader033.vdocuments.net/reader033/viewer/2022061221/54beb02b4a7959705b8b475e/html5/thumbnails/16.jpg)
The Risk of Injury….
• You do something too frequently without a break• You work in awkward position/ angles• Your workstation does not “fit” you• You have to stretch, bend or stoop too frequently• You lift things incorrectly • You are under discomfort• You are under significant pressure.
![Page 17: ILRI Ergonomics Training](https://reader033.vdocuments.net/reader033/viewer/2022061221/54beb02b4a7959705b8b475e/html5/thumbnails/17.jpg)

• One of the biggest injury risk factors is static posture.• Try to spend at least 5 minutes every hour away from your computer.• Remember to ONLY stretch to the point of mild tension.• Try to incorporate the stretches into your daily routine.• This slide provides some illustrations of simple active stretches to perform at the
office.
Hand Exercises• Tightly clench your hand into a fist and release, fanning out the fingers. Repeat 3
times
![Page 26: ILRI Ergonomics Training](https://reader033.vdocuments.net/reader033/viewer/2022061221/54beb02b4a7959705b8b475e/html5/thumbnails/26.jpg)
Back and Shoulder Exercises
Stand up straight, place your right hand on your left shoulder and move your head back gently. Do the same thing for the right shoulder
![Page 27: ILRI Ergonomics Training](https://reader033.vdocuments.net/reader033/viewer/2022061221/54beb02b4a7959705b8b475e/html5/thumbnails/27.jpg)
Head and Neck Exercises…
• Move head sideways from left to right and back to left
• Move head backwards and then forward
![Page 28: ILRI Ergonomics Training](https://reader033.vdocuments.net/reader033/viewer/2022061221/54beb02b4a7959705b8b475e/html5/thumbnails/28.jpg)
Computer and Desk Stretches…
Sitting at a computer for long periods often cause neck and shoulder stiffness and occasionally lower back pain.
Do these stretches every hour or so throughout the day or whenever you feel still.
Also be sure to get up and walk around the office whenever you think of it. You’ll feel better.

HOME ERGONOMICS
• It is about making your home a more comfortable, efficient and user-friendly living space.
• The ergonomics of your home greatly affect your body and its overall health.
![Page 35: ILRI Ergonomics Training](https://reader033.vdocuments.net/reader033/viewer/2022061221/54beb02b4a7959705b8b475e/html5/thumbnails/35.jpg)
THE KITCHEN
• Install a cushioned mat to stand on along the length of your kitchen
• Avoid round faucet knobs in all your sinks
• Purchase an oven that is mounted chest high, eliminating the need to bend over.
• Choose a refrigerator that has a bottom-mounted freezer, which reduces the need to bend over when accessing the main body of the fridge.
![Page 36: ILRI Ergonomics Training](https://reader033.vdocuments.net/reader033/viewer/2022061221/54beb02b4a7959705b8b475e/html5/thumbnails/36.jpg)
THE LIVING ROOM
• Make sure your living room furniture is easy to move
• Avoid couches that are too low and choose one with a proper lumbar support
• Buy a reading pillow or reading stand
• Avoid sitting in front of the television in a position where your neck is maintaining an upward tilt
• When eating in front of the television, place food on a surface that is high enough to eliminate the need to bend over to eat.
![Page 37: ILRI Ergonomics Training](https://reader033.vdocuments.net/reader033/viewer/2022061221/54beb02b4a7959705b8b475e/html5/thumbnails/37.jpg)
THE BEDROOM
• Use a cervical pillow that supports the natural curve or your neck.
• Use products that properly support your neck while reading or watching television in bed, to avoid “wry neck”
• Invest in a mattress that supports your spine without creating pressure points
![Page 38: ILRI Ergonomics Training](https://reader033.vdocuments.net/reader033/viewer/2022061221/54beb02b4a7959705b8b475e/html5/thumbnails/38.jpg)
THE BATHROOM
• Use bath, floor mats and install hand bars to provide good traction, prevent slips and falls.
• Bathroom sinks and showerheads not be too low
• Fit all faucets in the house with a user-friendly variety in which low force is necessary to turn the water on and off.
![Page 39: ILRI Ergonomics Training](https://reader033.vdocuments.net/reader033/viewer/2022061221/54beb02b4a7959705b8b475e/html5/thumbnails/39.jpg)
DO YOU SEE YOURSELF HERE…..
![Page 40: ILRI Ergonomics Training](https://reader033.vdocuments.net/reader033/viewer/2022061221/54beb02b4a7959705b8b475e/html5/thumbnails/40.jpg)
FOR YOUR BACK..
• Choose a vehicle that sits high above the curb—an SUV instead of a sports car—
• Enter the car first by sitting down and then swinging your legs under the wheel
• To leave your vehicle, slide the car seat back before swinging your legs out and planting your feet on the ground.
• Look for cars with automatic transmissions and power steering.
• Use a lumbar support cushion and add foam wedges to the seat to elevate pelvis
![Page 41: ILRI Ergonomics Training](https://reader033.vdocuments.net/reader033/viewer/2022061221/54beb02b4a7959705b8b475e/html5/thumbnails/41.jpg)
FOR YOUR NECKS AND SHOULDERS
• Avoid leaning forward when you sit in the driver’s seat
• Position the car seat so that you are comfortable and not stretching
• Make sure there is sufficient room between your head and the roof of the car
![Page 42: ILRI Ergonomics Training](https://reader033.vdocuments.net/reader033/viewer/2022061221/54beb02b4a7959705b8b475e/html5/thumbnails/42.jpg)
OPTIMAL CAR SEAT..
• Choose a comfortable and supportive seat
• Confirm that all adjustment mechanisms are easy to use
• Make sure the seat material does not create discomfort and all parts of the seat provide adequate support
• Children’s car seats to be light in weight , comfortable, adjustable and back/head/shoulder rests to fit the physique of each child.
![Page 43: ILRI Ergonomics Training](https://reader033.vdocuments.net/reader033/viewer/2022061221/54beb02b4a7959705b8b475e/html5/thumbnails/43.jpg)
ERGO DRIVING BREAKS
• To reset your spine and alleviate pressure caused by prolonged sitting, take advantage of red lights or sitting in traffic by doing some simple stretches
• Holding a steering wheel in awkward postures or too tightly can cause carpal tunnel syndrome
