10. Risk Waste – Infectious waste
Division in accordance with a Waste Management System:
Waste which need special attention for collection and treatment out of infectious preventive reasons.
Infectious waste
Origin: Blood and blood products, items contaminated with blood, serum or plasma and all contaminated waste from the diagnosis and treatment of patients with infectious diseases e.g. AIDS, Hepatitis, CJD, Cholera, Typhus, Dysentery, Tuberculosis, Meningitis, Diphtheria, Rabies,etc.

Disposal/Treatment: Treatment, collection and disposal under consideration of the characteristic of the chemicals

15. Risk Waste – Other Chemical waste
Division in accordance with a Waste Management System:
Acid Waste
Alkaline Waste
Solvents
Inorganic laboratory chemicals
Organic laboratory chemicals
Chemical waste
Origin: Laboratory, Research, etc.
Disposal/Treatment: This chemicals should be collected, transported and treated according to their chemical characteristics.

16. Risk Waste – Photo Chemicals

Fixing bathes, Bleaching-fixing bathes
Mercury, Cadmium, etc.
Amalgam, etc.
Heavy Metals
Origin: Laboratory, X-Ray, Dental Department, Wards, Technical department, etc.
Disposal: Photo Chemicals should be de-silvered and vaporized; Mercury, Amalgam must be separately collected and can be recycled. 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.

19. Packaging
Producer
Take the direct responsibility for the segregation and packaging process.
Segregate in the production sites.
Use coded bags and containers.

20. Receptacle for highly infectious waste
Puncture proof
Liquid proof
Irreversible closable
Autoclavable, without PVC
UN, local approved
Easy to handle
Coded

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.
