Abstract

Findings: In Quantitative measurements with weighing more than 2050 kg of normal, infectious and sharp wastes, the percentage of solid waste generation was 26.93%, infectious waste was 72.93%, and 0.1% was sharp and wastes wasted. Then, by calculating donation statistics per capita production The total waste per unit of donated unit was 0.277 kg per day and the per capita amount of infectious waste per kilogram was 0.202 kg per unit of donation per day (equivalent to 72.92% of total waste per capita). The highest amount of waste production was observed at Base No. 5 with an average of 394.49 kg / day and the lowest amount of waste production at base 8 with a mean of 21.74 / kg / day. Also, statistical tests with 95% confidence showed that there is a significant difference between the mean amount of waste produced in different parts of the bases; among these, the donor sector has the highest amount of normal waste and the laboratory section has the highest amount of infectious waste compared to other Sections produce. Also, the results of this study showed that in 66.7% of the cases, the Microbial vials had a positive response after 48 hours of incubation, and 57.2% of the devices were non-conforming with chemical and biological tests. Observations showed that among the used autoclaves, 44.5% of them were anticonvulsant autoclaves for infectious wastes (without chipping) and 55.5% were laboratory autoclaves. Also, in 100% of the laboratory autoclaves that were used to recycle waste, the results of the biologic tests were positive. By reviewing the IRAT checklist, the organization status was 94.37% (excellent), training 83.33% (excellent), classification and isolation was 72.86% (good), waste product information was 45% (poor), collected 85.53% (Excellent), waste transfer was 7.5% (critical), chemical waste was zero (critical), storage was 78% (excellent), and disposed and disposed of waste was 81.40% (excellent).
Conclusion: The results of this study showed that lack of knowledge of the potential hazards of chemical wastes, the imperfectness of the Material Safety Data Sheets (MSDS), and the lack of awareness of the correct disposal of chemical residues, the absence of policies or programs for the disposal of Chemical wastes, high volume of work in some centers and lack of attention to the issue of separation of wastes, lack of supervision over how to document waste production and daily weighing can be one of the causes of high percentage of infectious waste and weak and critical rating of some waste management parameters to be.
