Planning of CSSD
The CSSD can broadly
be classified into two parts
Central unit – Responsible for receiving dirty Utilities
cleaning, processing, Sterilization, storage and supply
Peripheral unit – Mainly responsible for distribution to
various areas of hospital.
– TSSU (Theater

Planning a Department
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
Structural Designing
• The
Central Unit comprises of three zones, separated by two distinct barriers
• One
collection window
• one
supply window on the other end

Cleaning area:
• High
capacity pass through washer disinfector at 800C to 900 C

and hot water streams
• Detergent
Solution
• Steam
when available
• Hot
air ovens for drying instruments
• Wall
fixtures for drying
Sterilization area
• Autoclaves
using dry heat, moist heat
• Ethylene
oxide sterilizers
• Testing

METHODS OF
STERILIZATION
Types of Autoclaving Machines
•
Downward
Displacement
•
Vacuum
Assisted.
•
Pulsed
Steam Dilution
Storage
•
After sterilization the sterilized items are
kept in different racks as per labeling
•
Supplied as per the demand of different area
