Under the Hierarchy of Hazard Controls, where does virtual (telehealth) consultation fall?

Virtual/telehealth consultation is classified as an Administrative Control — it is a practice change (policy/procedure) that reduces exposure by changing the workflow. Administrative controls include scheduling, policies, training, remote work, and telehealth. They are the 4th tier in the hierarchy. Engineering controls involve physical changes to the environment (ventilation, HEPA filters, barriers). Elimination would be canceling all appointments.
