Tray 1-A: NIOSH Investigations of WMSDs in Work Settings

Standard industrial classification

3751 Manufacturing (Motor vehicle parts)

Work setting and tasks

Manufacture of flywheels in motorcycle plant. Milling, assembly, truing, and balancing jobs were focus of evaluation.

Work-related musculoskeletal problems found

Hand/arm, back, and shoulder musculoskeletal disorders.

Ergonomic risk factors found

Excessive manual materials handling and lifting, awkward postures, hand/ arm vibration, and repetitive, forceful hammering.

Recommendations

Pre-post evaluations show that engineering controls recommended earlier have reduced risk factors and the number and severity of WMSD cases. Further controls include gravity conveyors, added hoists, and optimal workstation layouts to further reduce manual materials handling loads. Enhance efforts for early detection, awareness training of WMSDs, and risk factors.
