Paper Title
Ergonomic Evaluation of Hand Arm Vibrations among Carpentry Workers

Abstract
Ergonomic interventions in small and medium enterprises (SMEs) have been highly emphasized in several researchers' studies over the past few decades. SME workers are facing various health problems along with musculoskeletal disorders (MSDs) which make this study important. This study presents the results of an investigation conducted on carpenters from Jaipur, Rajasthan who were involved in hand-operated operations using vibrating and non-vibrating tools. The limit of vibration exposure of the hand arm is identified with the help of international standards. This is due to the known fact, since under repetitive load conditions the structure may result in its fatigue failure, the vibrating hand arm can sometimes be damaged in the same way. The duration of vibration exposure becomes an important parameter that needs to be measured by an appropriate method. Different types of tools are used in different ways; therefore, they are associated with disorders of various body parts. Despite the common causes of MSDs, the main cause of such disorders is hand arm vibration (HAV). The current state of the studies conducted reflects a clear future scope of more studies related to ergonomic interventions that can reduce HAV by optimizing important factors such as handle design, dimensions, handle grip and others.
