Toolbox Tray 1-A: NIOSH Investigations of WMSDs in Work Settings |
| Standard industrial classification
|
3751 Manufacturing (Motorcycles) |
| Work setting and tasks | Flywheel milling and assembly tasks in a motorcycle manufacturing plant. |
| Work-related musculoskeletal problems found | Upper limb, neck, and back |
| Ergonomic risk factors found | Repetitive, static, and forceful exertions, contact stress, awkward postures, heavy lifting, vibration |
| Recommendations | Specific engineering control recommendations include reducing the weight of the flywheel forging to reduce milling time and the weight handled, and improving the work layout to reduce manual material handling and excessive reaches. Work practice controls include training in better lifting techniques. Administrative controls, specifically job rotation, were recommended until engineering controls can be implemented. |
