The Human Body :The Human Body There are 639 muscles in human body


The Human Skeletal System :The Human Skeletal System There are 208 bones in adult human.


ERGONOMICS :ERGONOMICS Is concerned with the fitting between people and their work. Design in order to optimize human well-being and overall systems performance. The field is also called human engineering and human factors.


ERGONOMICS :ERGONOMICS SAFETY SIGNS is a part of Ergonomics.


Ergonomics :Ergonomics Personal Protective Devices: PPD’s


ERGONOMICS :ERGONOMICS


The Spine :The Spine Our back Is composed Of 3 natural curves that Form an S shape. When Our curves are aligned, Your ears, shoulders and Hips are in straight line. Good posture helps prevents Back strain and pain. Poor Posture can lead to pain and Serious injury.


The Three Curves :The Three Curves Cervical curve Neck Thoracic curve Middle back Lumbar curve Lower back


ERGONOMICS :ERGONOMICS


GOALS :GOALS It’s global aim is fitting the workplace to the worker It’s goal in the workplace is to prevent injuries and illness (work related musculoskeletal disorders or WMDs) by reducing or eliminating worker exposure to occupational hazards.


Five Aspects of Ergonomics :Five Aspects of Ergonomics SAFETY COMFORT EASE OF USE PRODUTIVITY / PERFORMANCE AESTHETICS


ERGONOMICS :ERGONOMICS


Lifting With Proper Posture :Lifting With Proper Posture Lifting is strenuous. It requires proper training and technique. Five steps Get close to the load Maintain your curves Tighten your stomach muscles Lift your legs Pivot don’t twist.


Picking Up a Heavy Object :Picking Up a Heavy Object Remember to get close To the object, bend at Knees, and lift with your Leg muscles. Don't bend At your waist.


Picking Up a Light Object :Picking Up a Light Object To lift a very light object From the floor, such as a Piece of paper, lean over The object slightly bend one And extend the other leg Behind you. Hold on to a Nearby chair or table for Support as you reach down To the object.


Holding an Heavy Object :Holding an Heavy Object While your are holding The object, keep your Slightly bent to maintain Your balance. If you have To move the object to one Side, avoid twisting your body. Point your toes in the Direction you want to move And pivot in that direction. Keep the object close to you When moving.


Placing an Object on a Shelf :Placing an Object on a Shelf If you must place an Object on a shelf, move as Close as possible to the Shelf. Spread your feet in A wide stance, positioning One foot in front of the Other to give you a solid Base support. Do not lean & don’t fully extend your Arms while holding the object In your hand.


Placing an Object on a Shelf :Placing an Object on a Shelf If the shelf is chest high, Move close to the shelf and Place your feet apart and 1 Foot forward. Lift the object Chest high keep your elbows At your side and position Your hands so you can push The object up and on to the Shelf. Remember to tighten Your stomach muscles before Lifting.


Supporting Your Back While Sitting: :Supporting Your Back While Sitting: When sitting keep your back in a normal slightly Arched position. Make sure Your chair supports your Lower back. Keep your head & shoulders erect. Make sure Your working surface is at Proper height so you don’t have To lean forward. Once an hour If possible stand & stretch. Place Your hands on your lower back And gently arch backward.


Slide 21:Ang ilang pangkaraniwang mga panganib sa trabaho at ilang pamamaraan kung paano kayo matutulungan ng ergonomics.


Shoulder (Balikat) :Shoulder (Balikat)


Hands, Hips, and Legs (Kamay, Balakang, mga Binti) :Hands, Hips, and Legs (Kamay, Balakang, mga Binti)


Poor Ergonomics :Poor Ergonomics This can lead to several Musculoskeletal Disorders (MSD)


Carpal Tunnel Syndrome :Carpal Tunnel Syndrome Inflammatory disorder that caused due to repetitive stress, physical injury or any condition that causes the tissues around the median nerve to inflate. Pinched nerve (Median nerve) in the wrist. Compression can be due to swollen tendons and thickened ligaments.


Carpal Tunnel Syndrome :Carpal Tunnel Syndrome Signs and Symptoms Pain Numbness Tingling sensation Prevention In between rest Exercise Management Analgesic Surgery


Tendonitis :Tendonitis Inflammation, irritation and swelling of a tendon. Occur as a result a results of injury, overuse or with aging as the tendon losses elasticity. Symptoms: Tenderness over the tendon Pain with movement of muscles & tendons Swelling of the tendon


Tendonitis :Tendonitis


Tendonitis: Causes :Tendonitis: Causes Physical work-related factors Intense, repeated and sustain exertion Awkward, sustained or extreme posture Insufficient recovery time bet. Activities Vibration and cold temperature Psychological work-related factors Time pressure, high work load Lack of peer support, poor supervisor employee relationship. Oral and Parenteral Fluoroquinolone Tx


Tendonitis: Prevention :Tendonitis: Prevention Warm up properly before activities. Stretch tendon before & after activity. Take frequent rest breaks Use proper form and posture If you feel pain in your tendons and joint, stop the activity. Choose footwear best suits the activity Stay in good shape.


Tendonitis: Treatment :Tendonitis: Treatment Stop activity that caused the pain Rest the affected area at least 3 weeks If possible, brace the area Apply anti-inflammatory to the area Re-evaluate after 3 weeks Light resistance movement / stretching Start light exercise Ease back into activity


Tendonitis: :Tendonitis:


Conclusion: :Conclusion: Ergonomics: Is at the center of all types of work situations and how comfortable we are in those working situations. Has to do largely with the safety of employees both long and short-term. Can help reduce company costs by improving safety. Can help reduce significantly the cases of work-related musculoskeletal disorders or WMD.
