7. PLANNING OF CSSD
The CSSD can broadly be classified into two parts
Central
unit
Peripheral
unit
-Responsible for receiving dirty
Utilities cleaning, processing,
Sterilization, storage and supply
- Mainly responsible for distribution
to various areas of hospital.
- TSSU (Theater Sterile Supply Unit)

10. LAY OUT DESIGNING PRINCIPLE
 There is no back tracking of sterile goods.
 One way movement from receiving counter to issue counter.
 Sterile area should be prior to sterile storage and issue.
 The receiving counter must be away from the issue counter.
 Separate receiving and issuing counter
There should minimum six basic division in CSSD

 It is a process of freeing an article from all living
organisms including bacteria ,fungal spores and viruses.
 A material is pronounced sterile if it
achieves 99.99% kill of bacterial spores.

21. 1.Indicator tapes
• Time, temperature, pressure sensitive tapes.
• Does not indicate for sensitivity for sterilization but only suggest the required
time and pressure the items have been subjected
2.Bacteriological indicator :
• Kept in center of pack before the process and later on subjected to lab for
colony count and growth
• A pack of non- pathogenic bacterial spore (stearo- thermopiles) is placed in
each load to check quality.
• If the level of sterilization is satisfactory, the green/ brown color change to black.
3.Personnel should be adequately trained to handle the equipments.
4.Regular maintenance of equipments be done.
5.The hospital infection control committee monitors the sterilization by drawing
samples and growing in medias for colony count.
QUALITY CONTROL
