Boning Table at Poultry Plant
To debone a chiocken breast with a knife.
This job requires frequent exertion of force, grasping, pushing, pulling, reaching, and constant standing. Among these risk factors, force, number of exertions in a given cycle, and posture are identified as key risk factors which contribute to the upper distal extremity injuries. Sustained non-neutral postures and localized mechanical stresses also contribute to injury.
The modified Lazy Susan is a device of 16-inch diameter, which is designed as a cutting surface for the chicken breast. This is a built-in, adjustable, rotating device so that the position of the chicken breast can be easily manipulated. A foot pedal would be able to adjust the height and angle of the Lazy Susan.
Evaluation of Intervention
- Reduces forces on the non-dominant hand
- Wrist remains in neutral during the cutting task, thereby eliminating awkward posture
- Lazy Susan is easy to clean and very durable
- Repetitive motion is not reduced
- Possible sliding of poultry on cutting surface
Semi-Quantitative Evaluation of Intervention
- Reduction of Identified Risk Factor
- No New Risk Factors Introduced
- Productivity not Reduced
- Low Cost
Other Possible Interventions
- New design of boning knife
- Increased steeling of knife
- Well-fitted gloves
