Ergo Safety for the Worker

Something's need a new design,

other just need a review

What is Ergonomics?

The study of work; OR

The discipline that matches thejob to the

worker

Benefits of Ergonomics

Decreased risk of injury

Increased productivity

Increased quality and efficiency Decrease lost work days

Decrease turnover

Improve morale

Ergonomic Hazards (Risk Factors)

Awkward working postures

Static postures

Forceful exertions

Repetitive movements

Pace of work

Point pressures

Temperature extremes Vibration

Ergonomic Risk Factors

To contribute to MSDs, risk factors mustbe present for sufficient duration,

frequency, or magnitude

Organizational Influences

Overtime

Workstation Design Guidelines

Reduce static component and allow worker to use

optimal posture (midpoint of limbs range of motion)

Avoid forward reaches in excess of 16

Elbows down close to the body flexor angle around 90

degrees

Sit-Stand preferred but rarely seen

Use gravity do not work against it

Avoid the need for excessive head movement

Avoid compression against hard/non-rounded edges

Approximately 20% of all work-related

injuries.

Approximately 25% of annual workers

compensation payments.

Most frequently injured body partaccording to the NSC.

ayout (obstacles) Posture (Torso flex, twisting, arms extended)

Environmental Factors (lighting, friction, temperature,humidity, vibration, PPE, personal risk factors)


23/30

Job Design - Lower Back

Minimize reach, lift, andcarry distances

Keep off floor (Lift fromknuckle height)

Work station design Limit travel distance to less

than 10 feet

Frequency

Relax time standard

Rotation

Work-Rest allowances

Minimize Weight

Mechanical aids

Carton capacity

Balance contents

Minimize Twisting

Provide Good Handles

Convert:

Carry to push/pull

Push over pull

Use large wheels


24/30

WORKPLACE USE OF BACK BELTS

Insufficient Data that belts significantly reduce

trunk loading

Insufficient data that wearing reduces risk of

injury based on IAP and EMG

May strain cardiovascular system

Insufficient data that discontinuation of use

increases risk among healthy workers * NIOSH does not recommend as prevention tool

Ergonomics A Comprehensive Plan

Have you addressed

the issue in your office


27/30

Your companies goal is to help workers

by reducing ergonomic injures in the

shortest possible time frame. This plan is

a major improvement over the rejectedrule because it will prevent ergonomics

injuries before they occur and reach a

much larger number of at-risk workers.


28/30

Industry and Task-SpecificGuidelines:

Work with stakeholders to develop industry

and task-specific guidelines for industries and

particular hazards

We will begin releasing guidelines this year


29/30

Strategy for Success:

Goals:

o Decrease ergonomic hazards

o Reduce injuries and illnesses

o Ensure flexibility and encourage innovation

o Help employers prevent MSDs

This is the best approach to achieve results quickly.
