The purpose of the article is aimed at raising concern on the implications of vibration on workers. Of particular interest is the risk on miners in Indian and the consequent effect relative to other areas of the world in terms of management and control. The paper scientifically analyzes how vibration occurs in a view to create our consciousness of related health consequences on the susceptible workers in mining firms.
The author points to 1977 International Labor recommendation as touching the putting in place of regulations to protect employees from vibration through certain criteria that includes limitation of the duration of exposure per time, and encouragement of regular medical check up to quantify the present cumulative effects of the hazard.
It discusses problems pose by vibration and legislative contribution in the exacerbation of the effects and submit in a thesis that there is a need to develop a practical management strategy for evaluation, monitoring and control of equipment-induced vibration in Indian mining industry due to severe ill-health mining poses on miners. In a view to understand approach at management of the resulting problems, the author types vibration into whole-body exposure and body segmental exposure. The categorization is equally aimed to assist in the understanding of the material which has different parameters in the determinant of magnitudes.
The understanding of the materials shows that constant exposure to vibration result in both vascular and neural disorders. The author’s method procedurally involves itemization of notable machineries and tools commonly used in mining industries to demonstrate the incidence of repeated exposure. Secondly, is the gathering of information from literature review of medical implications of vibration induced disorder from three non-indigenous authors. Thirdly, the author theoretically formulates determination of threshold vibration frequency that is pathological for various systems of human body.
The material researches into similar situation of vibration exposure in many regions of the world. The author progresses to evaluating the population of indigenous subject and quantifies the number of workers at risk in the two categories of exposure. In order to make provision for the author’s inability to measure optimum dose exposure per individual, there is presentation of a general formula to determine this from simple recording of exposure duration and equipment frequency. Finally, the author review and relate India’s legislative regulatory standard in the protection of workers to other developed nations like US, UK, and Canada.
The author’s finding quantitatively speculates that projections of teaming population of Indians miners are exposed to forms of vibration. He qualitatively discovers warm climate interplay that probably results in Indian’s complications with peripheral neuropathy and musculoskeletal abnormality and less pronounced circulatory effects. Furthermore, the insufficient data finds it impossible to determined standard causative dose of health risks. All are compounded by the legislature unspecific and unscientific guidelines in the evaluation and control of the occupational vibration in mining industries.
More importantly, the author dealt extensively on the health risk associated with mining vibration exposure. Section 2: Article Critique In the author’s thesis of the need to develop a practical management strategy for evaluation, monitoring and control of equipment-induced vibration in Indian mining industry due to severe ill-health it poses on large scale mechanization, the author fails to elaborate on past government effort as in the control and the positive or the negative outcomes.
Review of effectiveness of strategic control in line with legislative policies in other developed nations mentioned is necessary in order to evaluate the current position of Indian in a standard comparative study. The author lays much emphasis on the health statistic without a review of historical mortality relevance to the severe ill health claimed by theories. Less data is gotten of hospital cases. The two researched mining industry in Indian cannot by any means, provide a generalized extrapolation of population of miners who are susceptible to health risks.
Findings from concerned employees seem not to come up in the analysis. Since employees are directly involved in the study, one supposed that a provision for questionnaire who voice out issues from the direct sufferers. On the basis of information gap and undocumented studies of Indians’ miners on related issues, author’s interpretation of data is faulty. Though one may agree that the outcome of both author’s qualitative and quantitative results are products of limited resources.
More so, since there is no indigenous research on the subject matter, more efforts need to be invested in indigenous research before any logical conclusion could stand acceptable. Furthermore, since it is yet unproven with field studies that certain dose of exposure is required for listed medical diseases, the theoretical measurement of vibration dose is only best left paralleled without any connection with the study. The relevancies of theory and formulas of vibration to a certain dose with the risk of developing neural or vascular disease need to be substantiated by real-time survey for consolidated acceptance.
While one may be tempted to agree with the author’s conclusion, it would be safer to give the second chance of thorough review of indigenous materials in order to propose a more specific monitoring, controlling policy to safeguard the health of Indian miners. The orientation of the article needs to be more focused on regional policy unification of legislative measures. Reference Bibhuti B. Mandal, Anup K. Srivastava (n. d).
