Task 9: Trimmer/Clean-up
Employee
obtains separated pieces of poultry from conveyor and uses scissors to trim excess
skin, fat, and pieces of bone.
Hazards of
this task may include:
Ergonomic hazards from use of scissors
|
Hazardous Situation:
Use of traditional scissors forces the fingers to
repeatedly open and close the blade, which can stress tendons, increasing the risk of
tenosynovitis
and carpal tunnel. Contact trauma to sides of fingers can damage nerves, which can cause
numbness and tingling in the tips of the fingers and thumb.
Possible Solutions:
- Provide
pneumatic scissors;
these scissors can be activated by employees with little
finger force and with the wrist in a neutral posture.
- Provide
spring
activated scissors; these scissors open
automatically after each cutting motion.
- Rotate
workers to those
tasks that do not require scissor use.

Standing for a long time periods
|
Hazardous Situation:
Standing for a long time
reduces blood flow to the legs and forces isolated muscles to work for extended periods of
time increases risk of fatigue and varicose veins.
Possible Solutions:
- Install
sit/stand stools, which allow
employees to lean and have their weight supported while still remaining in an upright
posture.
- Rotate
employees to tasks that do not require prolonged standing.
-
Provide
shoe insoles that cushion the feet and spread foot pressure over a larger surface.
-
Provide a foot rest
in front of employees so they can shift their posture.

Reaching hazard
|
Hazardous Situation:
Employees repeatedly reach to conveyor or shelf to obtain
parts to be trimmed and reach to place finished parts in tubs or baskets. Repetitive reaching stresses the
shoulder and upper back.
Possible Solutions:
- Use
diverter
bars to push the product closer to the employee.
- Reduce width of supply conveyor so the product is presented
closer to the employee.
-
Position
product and work fixtures so all activities of the task can be performed with the elbows in
close to the torso.
-
Tilt work surface so
product slides to the employee.
