Woodworkers commonly perform operations like sawing, chipping, planning, shaping, nailing and drilling in daily work environment. This study focused the consequences of exposure to hand arm vibration among woodworkers working with handheld drill machine. Subjects’ hand grip strength was measured by a digital hand grip dynamometer. The vibration generated by a handheld drill machine was the main concern and hence the same handheld drill machine was used during this study. The results showed that workers exposed to hand arm vibration had higher prevalence of musculoskeletal disorders. Future studies should include other contributing factors also like ergonomic interventions and workers’ postures.
