Final answer:
The correct option is (2). Floors in the CS/SPD should typically be damp mopped at the end of each day to maintain cleanliness and prevent contamination.
Step-by-step explanation:
When considering the frequency of damp mopping of the floors in the Central Sterile Supply Department (CS/SPD), it is essential to maintain a high standard of cleanliness to prevent contamination and infection.
Typically, the floors should be damp mopped at the end of the day when the department is in operation. This ensures that any debris or contaminants that have accumulated during the day's activities are removed. More frequent cleaning may be necessary in cases of spills or significant contamination.
