OCCUPATIONAL HEALTH AND SAFETY RISK ASSESSMENT FOR PREVENTING ELECTRICAL INJURY IN UNDERGROUND MINING
Abstract
Risk assessment is a concept introduced for analysing the safety level in workplaces in order to assess if enough and proper precautions have been taken or if their number and quality should be improved so that to prevent hazardous situations. The underground coal mining industry is very hazardous, facing serious fatalities related to work, workplaces and workers as a consequence of the high-risk processes carried out underground and of the hazardous toxic and explosive atmosphere. The use of electrical equipment in such hazardous atmospheres (underground or surface) presents a series of particularities, the workers operating this equipment being exposed to electrical injury. The starting point for the optimization of the activity for preventing work accidents and occupational diseases in a system is represented by the risk assessment of that specific system. Regardless if it is a workplace, a workshop or an enterprise, such an analysis allows the ranking of risks depending on their dimension and the efficient allocation of resources for priority measures. Of the many methods used worldwide for assessing the risk of accidents, within this article is used a risk assessment method developed by a Romanian institute for research and development, the paper dealing with a case study in an underground coal hard coal mine carried out for presenting the practicality of this method, in case of assessing the risks of electrical injury of mining electricians.
