Background Ergonomics focus on evaluating the fit between the work environment and the worker with a goal of adapting the environment to reduce health risks, and to increase safety and performance (Mani et. al, 2016 & Robertson, Huang & Lee 2017). The Ergonomics Risk Factors (ERF) are situations that contribute against the principles of ergonomics which may cause harm to the health and well-being of workers (Jaffar et. al 2011). In line with ergonomics, Work Related Musculoskeletal Disorders (WMSDs)
Many important mechanical vibrations in tractors lie in the very high frequency range corresponding to rotation speed of 60-6000 rpm. Vibration describes the physical energy from a vibrating object, and also what we feel when that energy is transmitted to us. The main terms used to define this movement are “amplitude” and “frequency”. There are two of vibration occurs on Tractors operators : “segmental vibration”
interaction between humans and machines, as each side strove to produce more effective weapons systems. This led to a wave of interest in the area among researchers, and the formation of the Ergonomics Research Society in 1949. Traditionally, ergonomists have been concerned primarily with the physical characteristics of machines and systems, and how these affect
and assessment techniques are being used to calculate the probability of the negative events to determine the effectiveness of potential preventative actions. There are three points of preventative actions. Firstly, analyze process or conduct characteristics for negative trends that if a person is left alone, that person could be
years to develop and in other cases this can result in premature death. Many of those in the industry do not consult their doctor unless seriously ill and so levels of ill health are unclear. In developing countries where work is becoming increasingly mechanized, a number of work process have been developed that treat workers as tools in production, putting their health
