• Walls (when necessary)
• Operating room furniture
• Environmental contamination sources

The goal is to eliminate microorganisms that may cause infection transmission.

What Are the CDC Guidelines for Terminal Cleaning?

According to infection prevention principles promoted by the CDC, healthcare facilities should:

Why Is Operating Room Terminal Cleaning Important?

Operating rooms are high-risk environments where contamination can directly impact surgical outcomes.

Benefits include:

✔ Better accreditation performance

How to Terminal Clean an Operating Room?

Operating room terminal cleaning is typically performed:

• At the end of the day
• After contaminated procedures
• Following isolation cases
• During scheduled deep-cleaning periods
