The concept of ergonomics is central to the discussion on the effect of health and safety on productivity [1]. The aim of ergonomics is to ensure the well-being of worker by attaining optimal working conditions by using the most suitable physical characteristics and psychological capability [2]. Occupational and environmental respiratory diseases have a long history with respiratory disorders among tobacco workers [3]. As early as the beginning of the 18th century, ‘Ramazzini’ wrote about diseases of tobacco workers [4].
The study of the relationship between health and environment led to the conclusion that ill health was as a result of imbalance between human beings and environment. Technology changes work content and create new hazards while …show more content…
It is used to evaluate and monitor diseases that affect the lung function, monitor the effects of environment, monitor occupational exposures, assess risks of surgery and in pre-employment evaluation or for insurance purposes. The PEFR measures the movement of air into and out of the lungs during breathing. When lung function tests are used in monitoring the effects of occupational exposures or as an aid in diagnosis, the signal is usually the candidate’s results compared with the expected result for subjects without disease but similar in the personal characteristics that determine lung function such as gender, age, height and weight [7]. Monitoring of PEFR is useful only when adequate base-line studies are available for comparison. A change in a subject’s base-line value is more likely to indicate pulmonary injury than the traditional comparison of values measured in the subject with reference values obtained from population studies as a change from base-line of 5 to 10 percent may be significant for a person …show more content…
[16] reported that respiratory or nasal symptoms in cigar and cigarette making workers were significantly higher than control. Also, Mustjbegovic et al. [3] showed that tobacco workers tended to have lower forced vital capacity (FVC), forced expiratory volume in 1sec. Mwaiselage et al. [17] found that exposure to respiratory dust had significant correlation with a decrease in percentage cross-shift of peak expiratory flow (PEF) values. Abdel Rasoul et al. [18] found changes in the mean values of different spirometric measurements among exposed workers compared with control group which they attributed to sensitization to tobacco dust. The preliminary study carried out showed that many cigarettes manufacturing workers complained of respiratory symptoms and continuous exposure to tobacco dust reduced workers lung volume and peak expiratory flow rate
