Materials Handling: Ergonomic Principles Index

This index includes many general ergonomic principles that apply to electricians and smart practices that increase productivity and decrease risks of injury.


Example of Correct Posture: lifting with legs   Example of Incorrect Posture: lifting with lower back
Correct, neutral posture

Maintaining good posture helps workers to avoid injuries. Neutral posture means that the spine is aligned, postures are not exaggerated and do not strain the muscles and back. Neutral wrist posture is also important.

Economic benefits

Economic benefits are a by-product of practicing smart ergonomic practices. Productivity goes up as injury claims and missed workdays are reduced. Over time, insurance costs are reduced. Turnover is reduced when workers enjoy their jobs more and experience less injury.

HousekeepingHousekeeping

Establishing a strong housekeeping program will keep the work place tidy and reduce the risk of tripping over cords and debris. It also extends the life of tools and equipment, and results in increased productivity.

Lifting

Lifting properly is important. While there are some general lifting guidelines, a different approach may be needed for each load to be lifted. Sometimes it is appropriate to lift with the legs, and other times the back should be used to lift. These techniques depend on the size and shape of the load, and the frequency of lifting that is required.

Planning

Planning should be done with ergonomics in mind. Items to be planned include determining routes between staging areas and work spaces, scheduling for members of other trades, and knowing what services and utilities will be provided.

Power zonePower zone

The power zone for lifting is close to the body, between mid-thigh and mid-chest height. Comparable to the strike zone in baseball, this zone is where arms and back can lift the most with the least amount of effort.

Proper handholdsProper handholds

Proper handholds make lifting easier and reduce the risk of injury. Handholds should be made large enough to accommodate larger hands and should not dig into fingers and palms.

pushing and pullingPulling vs. Pushing

Pushing is generally preferable to pulling. Pushing allows the worker to use large muscle groups and apply more force to the load. Pulling carries a greater risk of strain and injury.

Staging

Staging is an important step in any electrical project. Proper staging includes placing materials as close as possible to work spaces, and storing materials at ideal heights so workers can utilize the power zone to take materials from storage.

Task Rotation

Rotating repetitive tasks allows different muscle groups to be used and reduces the risk of cumulative damage. Good planning makes this possible.
