What is Ergonomics?

ERGO=“work”

NOMICS= “rules” or “laws”

Ergonomics literally means “the laws of work”

SO EXACTLY WHAT IS

ERGONOMICS?

It is study of people efficiency at their working

environment.

It is one of the definition of Ergonomics.

It is understandable that there are different

definitions because ergonomics is all about

differences

DIFFERENCES

This differences call for

different designs in

equipment , furniture,

Workstations and routines.

This are differences in

size, shape, strength and

ability of individual

workers.

ERGONOMICS

Ergonomics is used

in a workplace to

help prevent

repetitive and

cumulative injuries.

3 Main Ergonomic Principles:

1. Work activities should permit worker to adopt

several different healthy and safe postures.

2. Muscle forces should be done by the largest

appropriate muscle groups available

3. Work activities s/b performed with joints at

about mid-point of their ROM (esp. head,trunk,

UE)

FACTS

The average person working at a keyboard can perform 50,000 to 200,000 keystrokes a day

Overexertion & falls are the most common cause of workplace injury

An average of 125,000 back injuries due to improper lifting each year.

Muscles overuse results in tiny tears in the muscles and scarring; these contribute to inflammation and muscle stiffness

Ergonomic Factors

Two Categories of Ergonomic Factors

1. Environmental

Hearing

Vision

General comfort and health

2. Physical

Environmental Factors

Some examples of ergonomic environmental problems

are:

Sick Building Syndrome

Excessive noise

Improper lighting

Temperature extremes

Physical Stressors

Physical stressors place pressure or stress on parts

of the body:

Joints, muscles, nerves, tendons, bones

Sometimes these injuries are referred to as

“Cumulative Trauma Disorders” (CTDs) or

“Repetitive Strain Injuries” (RSIs)

Types of Injuries

• Muscle pain

• Joint pain

• Swelling

• Numbness

• Restricted motion

• Repetitive stress injury

An ounce of Prevention is worth a

pound of cure !

What to do ??

a) Warm up & stretch before activities that are repetitive, static or prolonged

b) Take frequent breaks from ANY sustained posture every 20-30 minutes

c) Respect pain positions or stop painful activity

d) Recognize early signs of inflammatory process

Posture checkIncreased stress, decreased circulation…

PostureThink of posture in terms of joint position

Static and awkward postures lead to:

Decreased movement

Decreased circulation

Increased stress and fatigue

Maintain Neutral Posture

a) Maintain erect position of back& neck without shoulders relaxed

b) Position equipment & work directly in front of and close to your major tasks

c) Avoid static positions for prolonged time; muscles fatigue---MOVE to circulation!

Modify Tasks

a) Alternate activities frequently; rotate heavy &/or repetitive tasks without lighter less repetitive ones.

b) If stress become worse REASSESS task setup & look for alternative methods

c) Avoid repetitive or prolonged grip activities
