Control of OHS risks in the mining industry has been attracting increasing attention in recent years. Because of their great diversity in a complex system, hazards can be difficult to identify and classify, especially when system components interact. Risk cannot be managed successfully without comprehensive investigation of all its aspects. A coherent and integrated classification for identifying and categorizing all hazards is currently lacking in mining. We propose an integrated system classification of OHS hazards in mining based on our review of 44 studies retrieved using PRISMA. Considering Canadian and international standards, regulations and conventions, new hazard categories are proposed and hazard prevention is discussed from 12 perspectives: physical, chemical, biological, ergonomic, accident and psychosocial risks, as well as policy, legislation, management, design, geography, and uncertainty, with reference to each of the four phases of a typical mine life cycle, the hazards were shown in a portrait. This paper provides suitable categories based on rational data for creating a portrait in order to OHS hazards prevention in life cycle activity in mine.

Objective: To establish the possible aetiology of febrile children presenting with thrombocytopenia.Method: In this observational study, all children, aged 1 month to 18 years, admitted to paediatric wards of the ESIC Medical College & Postgraduate Institute of Medical Sciences and Research, Bengalaru, India, from October 2012 to September 2013, with fever and thrombocytopenia, were included. A thorough history was obtained and a general and systemic examination done. Routine investigations were done in all cases and specific investigations as and when required. Results: Of 1551 children admitted with febrile illness during the study period, 306 with thrombocytopenia fulfilled the inclusion criteria and were included in the study. Thirty five percent of children had mild thrombocytopenia. The commonest cause of thrombocytopenia was dengue fever (83%). The mortality was low (0.7%) and was seen only in dengue fever in our study. Conclusions: The commonest cause of febrile thrombocytopenia in this study was dengue fever, accounting for 83% of cases.Sri Lanka Journal of Child Health, 2018; 47(2): 146-148
