Vibration is quantified by amplitude or intensity and frequency. Frequency is the number of cycles a vibrating object completes in a second, measured in hertz (Hz). Amplitude is the distance at which the object moves from a stationary position to the extreme position on either side, quantified in meters (m). Speed is used to determine the intensity of vibration and varies from zero to a maximum per cycle of vibration, quantified in meters per second (m/s). Acceleration measures the rate of change of speed with time, quantified in units of meters per second or meters per second squared. It increases whenever a vibrating object moves further from its statutory position. Resonance also plays a critical role in the impact of vibration on the human body. Since each organ has its own resonant frequency, when an employee’s body is exposed to the vibration of similar frequency to a body organ, risks are greatly increased.
Exposure to hazardous levels of vibration is linked to adverse health outcomes. Some of the health problems caused by vibration are back pain, carpal tunnel syndrome, and vascular disorders. Vibration injury is derived from outdoor activities such as farming, transportation, forestry, shipping, and construction. Vibration exposure is divided into two categories: whole-body vibration (WBV) and segmental vibration or hand and arm vibration (HAV). Their sources differ as they affect different parts of the body, of different symptoms.
This is a mechanical vibration transmitted to the human being through part or segment of the body, mostly the hands or arms. Hand-arm vibration causes permanent adverse health effects collectively referred to as hand-arm vibration syndrome (HAVS) and specific diseases like carpal tunnel syndrome. ...Download file to see next pagesRead More

Health and Safety Strand

... Section A: Health & Safety Introduction Majority of individuals are ignorant of the fat that vibration exposure has the ability to haver health effects on them. The agricultural, industrial, construction, transportation and fishing sectors are some of the areas likely to expose individuals to vibrations. Whole body and hand to body are two main types of vibrations, where each causes particular health problems. The former has the potential to cause back pains. Individuals working in the industries where they handle heavy machinery may experience these problems. However, they may not know the immediate cause. It is indicated that most of them may not actually know that the vibration exposure may be the main cause. Hands to arm vibration...

Health and Safety (Exposure to vibration )

...?Health and Safety (Exposure to vibration) Exposure to vibration can cause adverse health effects in workers i. Describe the nature of occupational vibration exposure and the health effects of exposure to vibration; provide researched examples of affected workers or groups of workers. Vibration Exposure to vibration by workers has not been viewed as a health hazard by many. Vibrations can be felt, but the determination of its harmful effects remains next to impossible. Vibration is defined as oscillations instigated mechanically from an object and originate from an equilibrium point. The oscillations may be regular or random, depending on the source. In determination of the health effects of vibration, overall pressure waves generated...

Vibration Training

... as a solution (History of Whole Body Vibration). Vibration training is a technology and not a device. The device employed is the vibration platform. In whole body vibration training vibration platforms are used and the individual stands, sits, or lies prone on the vibration platform, depending on how and for what are the objectives in the use of the technology. The frequency and the strength of the vibrations can be adjusted for achieving different ends. The individual holds the required position on the vibrating platform, which may be in the standing on one foot or squatting with knees fully bent and so on for a selected period of time, like sixty seconds. Vibration training is thus a simple means for achieving certain desired health...

Policies to Enhance the Safety Measures

... and mental stress generating from workload or distraction, chances of occurring accidents are even more. In order to analyse the health and safety priority for the surgical service area, the North Staffordshire Combined Healthcare NHS Trust must play an imperative role in establishing safety culture amid the team, enhancing teamwork and most vitally developing the design of the healthcare equipment. Owing to the exposure of the risks related to contamination, the Board needs to be involved in forming effective communication to develop greater consciousness regarding health and safety amid the practitioners (Patient Safety First, n.d.). Conclusion Based on the above analysis and discussion, it can be affirmed that people working with health...

Health consequences from exposure to tetrachloroethylene

... Health Consequences from Exposure to Tetrachloroethylene Introduction Tetrachloroethylene or tetrachloroethane is a chlorocarbon. It is usually in liquid form and is colourless. The chemical is mainly used for dry-cleaning of fabrics and people usually refer to it as “dry-cleaning fluid.” Tetrachloroethylene is a potent solvent for organic substances. The chemical nature of this chlorocarbon causes it to be an important agent in various industries. Tetrachloroethylene is volatile but is highly stable and inflammable. The chemical is widely used in the dry-cleaning industry and in degreasing metal objects (EPA). Health wise tetrachloroethylene is a potent carcinogenic. It can cause cancers in the human body. The chemical acts as a central...

Mechanical vibration

... 2631-1 provide a criterion through which vibrations can be evaluated, analysed, and monitored. The purpose of this standard is to protect employees from unnecessary and harmful modes of vibration in the work place. The BS EN 14253:2003+A1:2007 is an essential document that aids in calculating vibration doses an employee gets when using vibration equipment. Through the calculations, the employee is assured of his health as well as good practices for vibratory equipment (Finucane, 2006). The document contains methods of measuring and establishing the daily exposure of vibration. This can then be compared to the required daily dosage units for the purpose of employee safety and health. 2. Referenced Norms in the BS EN 14253:2003+A1:2007...

... behavior’ (Lingard, 2002, p. 209). The effectiveness of training in the construction industry – referring especially to the health and safety training programs provided to the employees in the above industrial sector – was also explored by Goldenhar et al. (2001); their study led to the assumption that these programs can be quite effective but they are not adequately examined by the employers/ contractors; as a result the exposure of employees to hazards or their readiness to respond to the needs of construction projects are not appropriately evaluated. It is concluded that an appropriately customized health and safety training program should be provided to the employees that will participate in the specific project; however, it would...
