Introduction Ergonomics “The scientific discipline concerned with understanding of interactions among humans and other elements of a system, and the profession that applies theory, principles, methods and data to design in order to optimize human well-being and overall system performance”
Slide 6-

Introduction Ergonomics means “fitting the job to the worker,” including: Work stations Tools Equipment Ergo = Work Nomos = Law
Slide 7-

Introduction Why is ergonomics important? Overexertion leading cause of injuries Most costly Recurring/Persistent pain may develop in future Bodily reaction is another leading cause of injuries in workplace Repetitive motion also within top 10 most common workplace injuries
Slide 8-

Common Work-Related MSDs Discomfort Pain Numbness Loss of motion/flexibility Spasticity Stiff joints Burning Swelling Tingling Inflammation Throbbing Paralysis Musculoskeletal Disorders (MSDs) Affect the muscles, nerves, blood vessels, ligaments, and tendons Symptoms

Common Work-Related MSDs Common MSD disorders: Carpal Tunnel Syndrome Tennis Elbow Bursitis Ischemia De Quervain’s Sciatica Herniated Discs Neck strain/disability Tendinitis Rotator Cuff Neuritis Reynaud’s Syndrome Trigger Finger Thoracic Outlet Syndrome Epicondylitis Back strain/disability

Ergonomic Control Methods Environmental ergonomic hazards: Amplify/increase risk of MSDs Examples Hot weather Cold weather – affects worker coordination and dexterity High-temperature indoor (steam rooms, attics) Cold-temperature indoor (walk-in freezers, cold process rooms) Low visibility
Slide 49-

Employer/Employee Requirements General Duty Clause Each Employer: Shall furnish to each of his employees employment and a place of employment which are free from recognized hazards that are causing or are likely to cause death or serious physical harm to his employees; Shall comply with occupational safety and health standards promulgated under this Act. Each Employee: Shall comply with occupational safety and health standards and all rules, regulations, and orders issued pursuant to this Act which are applicable to his own actions and conduct.
Slide 50-

Report signs or symptoms if: Pain is persistent, severe or worsening Pain radiates Symptoms include numbness or tingling Symptoms keep you from sleeping at night Fingers blanch or turning white Employee/Employer Requirements
Slide 51-

Getting involved: Look at jobs Come up with solutions Work with solutions Take part in training Take responsibility for changing the way you do your job Help to make sure efforts are successful Employee/Employer Requirements
Slide 52-

Five Key Points to Remember Ergonomics can help you on your job WMSDs can happen in jobs with risk factors Risk factors can be reduced and WMSDs prevented Reporting signs and symptoms early is important You can help your company put ergonomics changes into place
