Plastic barriers cover the light handles, chair controls, and air-water syringe. How should they be managed?

Barriers are removed with gloved hands after each patient, discarded, and replaced with fresh barriers once hands have been cleaned and regloved, since the barrier surface is considered contaminated. Wiping a barrier and reusing it defeats its purpose. Contamination is frequently invisible, so leaving barriers up for a day, a week, or until they look dirty allows cross-contamination.
