This document provides guidance for health care facilities (see 3.9) and offsite reprocessing centers (see 3.11) for the external transportation of processed medical devices (see 3.10) between these facilities (e.g., from one health care facility to another, between offsite reprocessing center and health care facility). It provides guidance on maintaining the integrity of sterilized items and transport for contaminated (see 3.3) and processed (see 3.14) items. This TIR does not provide guidance for transport of single use items which are supplied sterile from the manufacturer. Single use sterile items are often transported alongside items that have been processed by the facility, such as a picked/loaded case cart.
