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

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
8/8/2019 Ergo Safety for the Worker
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.

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

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.
