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.

Housekeeping
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
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
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. |
Pulling 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. |
