Task 2: Tail Cutter
The tail is
cut from the bird before the bird is placed on the cone. A standard scissors is
generally used to perform the operation.
Hazards of this task may include:
|
Ergonomic hazards from use of scissors
|
Hazardous Situation:
Using 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
for cutting off tail; these scissors can be activated by employees with little finger
force and with the wrist in a neutral posture.
- Provide
spring
activated scissors for cutting off tail; these scissors open
automatically after each cutting motion.
- Rotate
to tasks that do not require using scissors.

Standing for a long time
|
Hazardous Situation:
Standing for a long time reduces blood flow to the legs, forces isolated muscles to work for
an extended time, and 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 lift one foot, allowing them to
continually shift their posture.
