Final answer:
One safe practice of aseptic technique is maintaining a sterile field using protocols that involve sterilized materials and procedures to prevent contamination and sepsis.
Step-by-step explanation:
A safe practice that is part of using aseptic technique includes maintaining a sterile field for medical procedures that carry a risk of contamination, to prevent sepsis. This involves following protocols for using sterilized materials, proper hand washing, and the application of sterilants. Furthermore, in microbiology labs, aseptic techniques involve practices such as flaming the openings of tubes or bottles to reduce airborne contaminants, using pre-sterilized pipettes and culture tubes, and sterilizing metal tools by heating.
