Implementation of ergonomic programs to reduce sick leave due to low back pain among nickel mining operators

Whole body vibration (WBV) has been recognized as a main risk factor for low back pain (LBP) in coal mining activities. Heavy equipment operators in nickel mining may be exposed to a higher LBP risk due to the land condition of the overburden overlying nickel deposits, which is less stable than that of coal deposits. This report summarizes the efforts of a nickel company in managing LBP complaints among mining operators. The programs included risk assessment and mitigation, musculoskeletal complaint management, LBP training, and macroergonomic intervention. These programs were integrated into the occupational health management system of the company. Within a 3-year period, a decrease in LBP-related sick leave was reported. The present report shows how ergonomic programs may help to manage LBP and could be extended to other musculoskeletal cases.
