1) Policy
– Waste disposal direction shall be taken special note to prevent hospital infection.
– Infections wastes shall be handled, kept strictly and burned by a incineration located at hospital website.
2) Waste Disposal Plan
- a)Classification
– Medical wastes in hospital have been categorized as follows;
| Infections Waste | Specially-controlled waste | Organ, needle, etc. |
| Industrial waste | Rubber gloves, etc. | |
| General waste | Gauze, etc. | |
| General Waste | Plastic, Rubber | Infusion bottle, etc. |
| Paper, wood, Vinyl | Voucher, etc. | |
| Metal, Glass | Can, Glass bottle |
- b) Infections Waste Disposal
– Segregation: Infections waste disposal shall be segregated appropriately and packed in particular containers and delivered to particular storage. The segregation, packing and delivery shall be operated appropriately at every room such as outpatient, performance theater, blood collection room and dialysis room.
– Precaution: Infections waste shall not be place in other containers on the means of segregation, packing and delivery.
– Storage: Infections waste shall be kept in the storage in hospital website temporarily until infections waste is incinerated.
– Incinerator:
It is intended to sterilize medical waste, reduce its quantity, and render its components unrecognizable all in a single fully enclosed and automatic system.
It unites guide heated steam, higher pressure and shredding to take care of infectious substances.
The contaminated waste is loaded into the top stainless steel room where a heavy-duty shredder reduces the waste to small pieces. Using gravity, then the processed material falls to the treatment room where each piece is heated to 134 and pressurized to 3 to pub for 20 minutes. The working conditions are always tracked and verified to achieve complete sterilization.
The 60 minutes average length process cycle is completely automated. A computerized program monitors the process and automatically prints a report together with the fundamental sterilizing parameters in the close of the cycle for accurate record keeping.
The capacity is between 500 to 600 kg/cy.h or longer.
Treatment bicycle:
1- Loading; the contaminated waste is automatically -loaded to the room of the unit
2-Shredding; the heavy-duty shredder cut the material into small pieces and features a unique reversing system to avoid jamming
3-Heat; saturated pressurized steam raises the temperature to 134 C along with the strain to 3 pub
4-Sterilization; the sterilization comes into direct contact with all the shredding material (134 c , 3 bar) to get 20 minutes
5-Cooling; temperature is lowered to 80 C by spraying cool water onto Double coat of the treatment vessel, simultaneously, the unit returns to ambient pressure
6-Draining; the steam is condensed to water and discharged together with the cooling water to the sanitary sewer system
7-vacuum; the residual residual steam is vented through a vacuum pump
8-Unloading; an electronic sign informs the operator which all safe working conditions have been met
The condition unlocks the unit and allows air unloading of the treated waste into a container
