ERGONOMICS FOR THE 21ST CENTURY OFFICE OF RISK MANAGEMENT LOSS PREVENTION UNIT
Slide 2-

PRE-TEST What is ergonomics? What are MSDs? What are symptoms of MSD? How can I evaluate my workplace? What are some ergonomic solutions?
Slide 3-

COURSE OBJECTIVES Define ergonomics Establish ergonomics in the workplace Introduce basic skills in the recognition & control of occupational ergonomic hazards Introduce ergonomic exercises.
Slide 4-

PROGRAM GOAL To minimize injuries due to chronic physical and psychological stresses, while maximizing productivity and efficiency
Slide 5-

ERGONOMICS DEFINED Ergonomics is the science of fitting the job to the worker.
Slide 6-

BIOMECHANICS The science of measuring the amount of force put on the muscles and joints of people when working in different positions.
Slide 7-

BIOMECHANICS CONT. STATIC - Holding one object or body part in one position for an extended period. EX. Standing or sitting in a parking booth or at a microscope.
Slide 8-

BIOMECHANICS CONT. DYNAMIC - An activity created by the rhythmic contraction and relaxation of the muscles. EX. Walking
Slide 9-

DID YOU KNOW? As early as the 1700’s scientists were aware of repetitive movement injuries to workers. Bernardino Ramazzini (1633-1714) Clerks Cobblers and tailors Porters
Slide 10-

ERGONOMIC STUDY AREAS WORKERS - what they bring to the job TOOLS - what they bring to the worker
Slide 11-

ERGONOMIC STUDY AREAS TASKS - what the worker must do ENVIRONMENT- the conditions surrounding the worker and the tool
Slide 12-

ERGONOMIC FOCUS The Tool The Task The Work Station and Environment The User /Operator
Slide 13-

RESULTING INJURIES ARE CALLED: Cumulative Trauma Disorders (CTD), Or Repetitive Strain Injuries (RSI), Or Musculoskeletal Disorders (MSD)
Slide 14-

HOW SERIOUS ARE MSD MSD account for: 1/3 of all lost day injuries each year These injuries cost business $15-20 billion in worker’s compensation each year
Slide 15-

COMMON CAUSES: Repetitive and/or prolonged activities Awkward postures/positions for an extended time Static postures Vibration High/low Temperatures for an extended time Forceful exertions
Slide 16-

ERGONOMIC STRESS AREAS Knee Hip
Slide 17-

SIGNS OF MSD Decreased range of motion Loss of function Deformity Cramping Loss of color Decreased grip strength Loss of balance Swelling Redness
Slide 18-

SYMPTOMS OF MSD Muscle fatigue or pain Aching Burning Numbness Stiffness Tingling
Slide 19-

EXAMPLES OF MSD TENDONITIS- An inflammation of the tendon. Typically occurs in the shoulder, wrist, hands, or elbow. CARPAL TUNNEL SYNDROME- Irritation of the median nerve, which runs through a bony channel in the wrist called the carpal tunnel. Usually results from excessive flexing or twisting of the wrist.
Slide 20-

CARPAL TUNNEL SYNDROME
Slide 21-

MSD CONT. TRIGGER FINGER SYNDROME- Tendons in the fingers become inflamed, causing pain, swelling, and a loss of dexterity. EYE STRAIN - The eyes become strained as a result of poor lighting, glare or viewing from awkward positions.
Slide 22-

MSD CONT. HAND/ARM VIBRATION SYNDROME- Tingling, numbness, blanching, loss of dexterity in the hand/arm MUSCLE STRAIN – Pain in muscles

WHAT CAN WE DO? Administrative controls Work practice controls Engineering controls
Slide 25-

ADMINISTRATIVE CONTROLS Employee rotation/job task expansion Physical adjustments to the work pace Redesign of work methods Alternative tasks Breaks
Slide 26-

WORK PRACTICE CONTROLS Safe & proper work techniques & procedures Training Physical conditioning period
