Abstract
Backgrounds and Objectives: Medical waste management is one of the important issues in solid waste managment in each community. This research was carried out to study the quantity, quality and the management practices of solid wastes of hospitals in Zanjan City in 2011.
Materials and Methods: In the present study, the hospital wastes were categoried and weighted into four main categories. Waste management pattern was studied based on a checklist extracted from national guidelines. Then, hospitals were ranked from very poor to excellent classes. For data analysis, Excel soft ware was used.
Results: Waste generation rate was on average 2.402± 0.163 Kg/bed.day in the studied hospitals. The generation rate of domestic waste, infectious waste, sharp wastes, and chemical - pharmacological waste was 1.432±0.059, 0.926±0.096, 0.029±0.0055, and 0.015±0.002 kg/day.bed respectively. The status of the waste management practices was determined as average.
Conclusion: Waste generation rate in the hospitals of Zanjan was lower compared with the expected average value in other cities (e.g. 2.71 Kg/bed.day in Tehran). The percentage of medical waste in Zanjan hospitals was 34, which is higher than W.H.O. recommendations. Therefore, it is strongly recommended to reform and monitor certain solid waste management practices in order to reduce health and environmental issues.

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.
