Abstract :

Background and objective: Hospital wastes are the second hazardous wastes after radioactive wastes. Proper management of this wastes cause to affordable disposal of hospital wastes which is also compatible with the environment. The present study has been done to evaluate the quantity of waste produced and also the function of safety methods in Sari's hospitals. Method: Required data were collected by going to the production and storage of waste and assessment of the devices function have been done based on biological monitoring of indicator bacteria in infectious wastes. Findings: Average of total wastes produced were 3198 kg per day in Sari's hospitals and per capita waste production were estimated kg per bed per day 2.49. Average of normal wastes, infectious wastes and winning wastes and radiation wastes were determined per bed respectively, 1.56, 0.7, 0.22, 0.01 kg per day. The total wastes and infectious wastes in private hospitals were more than of public hospitals and Social Security. The results showed that 46% and 36% of infectious wastes have been annihilated by incineration and safe methods respectively. Biological monitoring showed that the most of function Safety devices were at an acceptable level in hospitals. They have been eliminated with an average 80% of microorganisms. Discussion and conclusion: Waste production in the most of our hospitals, especially private hospitals, are much higher than usual offered by the World Health Organization. The results show that the size of hospitals (large or small) have no influence in the production of solid waste per bed, and there were related to the type of ownership and management procedures largely.
