Which action is NOT permitted in the sterile compounding process?

In sterile compounding, maintaining the integrity of the sterile environment is crucial to preventing contamination of the products being prepared. Applying hair spray is not permitted because it can introduce airborne particles and aerosols into the sterile area, increasing the risk of contamination. The use of personal grooming products like hair spray can lead to particulate matter settling onto surfaces and into the air, compromising the sterile conditions necessary for compounding.

On the other hand, wearing a mask, using gloves, and washing hands are essential practices in the sterile compounding process. Masks help reduce the risk of respiratory droplets contaminating the work area, gloves protect the compounding area from direct contact with contaminants, and thorough hand washing is fundamental in removing any residual microorganisms before starting the compounding process. These protocols are key to ensuring that compounded sterile preparations remain safe and effective for patient use.
