Drivers of earth-moving machines are exposed to whole-body vibration (WBV). In mining operations there can be a combination of relatively high magnitudes of vibration and long exposure times. Effective risk mitigation requires understanding of the main aspects of a task that pose a hazard to health. There are very few published studies of WBV exposure from India. This paper reports on a study that considered the contribution of the component phases of dumper operations, on the overall vibration exposure of the drivers. It shows that vibration magnitudes are relatively high, and that haulage tasks are the main contributor to the exposure. It is recommended that driver speed, haul road surfaces and vehicle maintenance/selection are optimized to ensure minimization of vibration. If this is not sufficient, operation times might need to be reduced in order to ensure that the health guidance caution zone from Standard No. ISO 2631-1:1997 is not exceeded. © 2016 Central Institute for Labour Protection – National Research Institute CIOP-PIB.

The 60-film set was developed by experts (Expert Group) for examining 8 indices: sensitivity (X 1) and specificity (X 2) for pneumoconiosis, sensitivity(X 3) and specificity for (X 4) large opacities, sensitivity (X 5) and specificity (X 6) for pleural plaque, profusion increment consistency for small opacities (X 7), and shape differentiation for small opacities (X 8) of physicians' reading skills on pneumoconiosis X-ray according to ILO 2000 Classification. The aim of this study was to assess the appropriateness of the exam film set for evaluating physicians' reading skills. 29 physicians (Al-Group) and 24 physicians (A2-Group) attended the 1st and 2nd Asian Intensive Reader of Pneumoconioses (AIR Pneumo) training course, respectively, and 22 physicians (B-Group) attended Brazilian training course. After training, they took examination of reading 60-film exam set. The examinees' reading results in terms of 8 indices were compared between the examinee groups and the Expert Group by parametric unpaired /-test. The Examinee Group consisting of Al-Group, A2-Group and B-Group was inferior to the Expert Group in all indices. There was no significant difference for X 7 of Al-Group, X 7 and X 8 of A2-Group (p>0.05) compared with the Expert Group. There was a significant difference in X 8 at /K0.05 between Al-Group and A2-Group, in X 3 at /><0.05 between Al-Group and B-Group, in both Xj and in X 3 at/>0.05 between A2-Group and B-Group. Accordingly, the 60-film set providing 8 indices designed might be a good method for evaluation of the physicians' reading proficiency at different training settings. © 2012 National Institute of Occupational Safety and Health.

In the present study, antiimplantation activity of methanolic extract of Balanites aegyptiaca Delile bark was evaluated. The methanolic bark extract of Balanites aegyptiaca showed significant antiimplantation activity. Pretreatment with methanolic extract showed significant inhibition of number of implant site at a dose of 300-mg/kg-body weight. There was no change in ovulation; hence the antiimplantation activity observed in the present study with Balanites aegyptiaca bark can be attributed largely to its inhibition of number of implants. However, an investigation of the antiimplantation activity showed no increase in body weight or uterine content of blood glucose, cholesterol and triglyceride levels when compared with control group. © RJPT All right reserved.

22 locations in two coal preparation plants in India were evaluated in regard to their vibration characteristics and probable effects on the health of the operators and supervisors of those plants. In some cases notwithstanding the apparently sufficient isolation, vibration was found to be comparatively high. Seven hours as maximum possible exposure duration in any posture in a shift has been adopted in this study. Based on a comparative ranking DMC, vibrating screens, belt conveyors etc, in that order, pose certain health risk to the plant operators in terms of whole body vibration. The hazard potential was found to be related with the make of equipment, nature of installation, operating principles, operating practices, equipment capacity, etc. This exploratory study indicates that epidemiological studies should be conducted in large number of coal preparation plants to ascertain the nature of effects on health due to foot transmitted vibration in tropical climate, though risk assessment models from ISO Standards might not be effectively applied in such cases.

Fisheries industry in India is an unorganized sector of occupation where considerable proportion of workers is female. However, the prevalent gender inequality in terms of task allocation, wages, and other welfare facilities makes the men as dominant workforce. Furthermore, there are occasions when incidents of workplace violence take place. The present study was conducted to find the prevalence of workplace violence at worksite and study gender bias in such events. In a cross-sectional study 171 fishermen and fisherwomen were interviewed to collect information about workplace violence. The overall prevalence of workplace violence reported was 14.6%. This included 2 (8%) cases of physical assault, 1 (4%) case of sexual harassment of fisherwoman by her colleague and 22 (88%) cases of verbal abuse. A significant (p=0.002) association was found between gender and verbal abuse at the workplace. In conclusion, this study highlighted the occurrence of workplace violence among fishery workers in India. There was a gender bias towards females that can be attributed to male dominance in this occupation. © 2016, NIOC Health Organization. All rights reserved. Source
