The healthcare market in the KSA can be divided as follows : HOSPITALS Ministry of Health – 27,279 Beds Private Sector – 8,766 Beds Other Governmental Sectors – 9,169 Beds Total = 45,214 Beds At average of 1.13 kg/bed/day - Total quantity of HCW = 51 tons per day = 18,615 tons / year 2. PHC’s & CLINICS At average of 0.08 kg/visitor/day – Total quantity = 7,626 tons / year TOTAL = 26,421 tons/ year = 71,893 kg / day

Batteries, fluorescent lamps, etc. can be treated in treatment plants.

17 Risk Waste – Radioactive and Cytotoxic waste
Division in accordance with a Waste Management System: Genotoxic Waste Radioactive Waste Pressurized Containers Radioactive W. Genotoxic W. Containers Origin: Cancer treatment, Nuclear medicine, Laboratory, Research, Engineering department, etc. Disposal/: Genotoxic waste can be treated by special waste incineration (> 1200°C), radioactive waste can be interim stored, pressurized containers are not allowed to be incinerated in any way.

22 Cleaning and supply staff often do not know the real significance.
Labelling The internationally valid symbol for infectious substances has to be used in all cases when healthcare waste is being handled. The hospital has to guarantee that all bags and containers are labelled with this sign. Experience from many hospitals is that not all of the staff is aware that the symbol is important for any person dealing with healthcare waste. Cleaning and supply staff often do not know the real significance.
