Volume 10, Issue 1 (6-2017)
Abstract

Background and Objective: Identification of potential risks in laboratories and trying to create safe conditions for the staff is very important from different aspects. The main objective of this study was to evaluate the potential risks in the laboratories of three research centers affiliated to Iranian Fisheries Science Research Institute.

Materials and Methods: In order to assess and classify risks associated with working in the laboratories (11 laboratories of the Persian Gulf and Oman Sea Ecological Research Center, 9 laboratories of National Shrimp Research Center and 2 laboratories of National Aquatic Organisms Processing Center), the method of "Failure Mode Effects Analysis" (FMEA) as well as statistical methods (concerning compare means) were used.

Results: The risk levels in all the laboratories of the Persian Gulf and Oman Sea Ecological Research Center, except for benthos laboratory, could be evaluated as moderate or high. Only in the case of the sample preparation laboratory, significant differences between the values ​​of RPN before and after corrective action was observed. However, in this case the corrective actions have not been effective in decreasing the risk level. In most laboratories of National Shrimp Research Center, the corrective actions were effective in reducing the risk levels (with the exception of three laboratories). In both laboratories of National Aquatic Organisms Processing Center, after the corrective actions, the risk levels were sharply reduced.

Conclusion: Considering the high level of risk in many evaluated laboratories, appropriate corrective actions were proposed. But after the second-stage evaluation, it was realized that the proposed corrective measures in some laboratories (especially in the Persian Gulf and Oman Sea Ecological Research Center) were notperformed sufficiently and hence the risk still was remained at critical or semi-critical level


Risk detection and assessment of hospital waste management and approaches for risks reduction in children's medical center hospital using failure mode and effects analysis

Volume 10, Issue 3 (12-2017)
Abstract
Background and Objective: The failure mode and effects analysis (FMEA) is one of risk assessment techniques. The aim of this study was to identify, assess and prioritize the risk associated with the process of medical waste management using the FMEA method and provide appropriate strategies and measures for controlling the risk of this process in the Children's Medical Center Hospital.
Materials and Methods: This descriptive cross-sectional study was performed in this hospital during the first 6 months of 2016. For data collection, the standard worksheet of FMEA and object-oriented sampling were used. In this method, each error based on the severity, the occurrence rate and probability of finding an error is scored between 1 and 10, which the priority number of the risk is obtained from the product of these 3 indicators.
Results: In this study, a total of 33 potential risks associated with the management of medical wastes were identified using FMEA risk assessments. The highest priority number for non-washed waste containers is 360 and the lowest priority number is the risk of not having the Safety box for disposal of sharp waste in the wards, which is 30.
Conclusion: One of the most important sources of environmental pollution is medical wastes that have high costs in different stages of waste management in the hospital, thus, the use of the FMEA technique can reduce costs and increase the safety and health of the personnel. It also helps to preserve the environment.

Abstract
Background and Objective: The health and safety of the employees of any industry is one of the most important issues to prevent the occurrence of accidents. This study aimed to identify and assess related risks in a battery-manufacturing industry using FMEA method and estimate the ratio of the cost of accidents to prevention.
Materials and Methods: In this descriptive and analytical study, the production activities of the industry were first identified. Then the work process, employee duties, and Potential risks were determined by the HAZID method. Evaluation and prioritization of risks were done using FMEA method. Risks whose RPN was higher than 145 were determined as important risks and the ratio of incident cost to accident prevention was calculated.
Results: In 62 active units of this industry, 716 risks were identified and prioritized, 16 of which (2.23%) had RPN above 145 with the highest priority. The financial pulp unit with falling and fire hazards and the assembly unit with the risk of fumes and lead dust leakage with RPN 245 were among the most dangerous units and hazards identified in the industry. In all units except one unit, the ratio of the cost of accidents to prevention varied from 1.2 to 25.
Conclusion: The results showed that it is necessary to consider the correction of the important risks by the industry officials, according to the set priorities so that potential accidents caused by these risks are minimized. This prioritization can play an effective role in optimal risk management and reduce related costs.
