Slide 9: Preparing the Operatory

•	Identify surfaces: Determine which surfaces need to be covered or disinfected.

•	Use barriers: Apply plastic or foil barriers to surfaces that are difficult to clean, like electrical switches.

Slide 10-13: X-Ray Machine Preparation

•	Cover components: Ensure the tubehead, position-indicating device (PID), control panel, and exposure button are either covered with barriers or disinfected.

•	Disinfection: Use EPA-registered hospital-grade disinfectant for surfaces that are not covered.

Slide 14-18: Work Area Preparation

•	Set up work area: Disinfect the area where x-ray film and film-holding devices are placed during exposure.

•	Use barriers: Place barriers such as paper sheets, paper towels, or plastic covers. After procedures, discard barriers and clean the surfaces.

Slide 19-24: Infection Control During Exposure

•	Avoid contamination: After putting on gloves, touch as few surfaces as possible.

•	Wipe films: After removing films from the patient’s mouth, wipe them with a paper towel to remove saliva.

Slide 25-29: Handling Contaminated Films

•	Contain films: Place wiped films in a disposable container, such as a plastic bag or paper cup labeled with the patient’s name.

•	Transport carefully: The container should not be touched with gloved hands. Transport films to the darkroom only after removing gloves and washing hands.

Slide 30-33: Film-Holding Devices

•	Use disposable or sterilize: Film-holding devices should either be disposable or sterilized/high-level disinfected before reuse.

•	Packaging: Keep sterilized devices packaged until the patient is seated to ensure visible hygiene practices.

Slide 34-37: Post-Exposure Management

•	Discard contaminated items: Dispose of all contaminated items and disinfect any uncovered surfaces.

•	Handwashing: Remove gloves and wash hands after handling contaminated items.

•	Surface disinfection: Use an EPA-registered disinfectant for cleaning exposed surfaces.
