Glossary of Terms
The removal, usually with detergent and water, of adherent visible soil, blood, protein substances, microorganisms, and other debris from the surfaces, instruments, devices, and equipment, by a manual or mechanical process that prepares the items for safe handling and/or further decontamination, i.e. before using heat or chemicals, disinfection or sterilisation.
Exposure-prone procedures (EPPs) include procedures where the worker's gloved hands may be in contact with sharp instruments, needle tips or sharp tissues inside a patient's open body cavity, wound or confined anatomical space, where the hands or fingertips may not be completely visible at all times. However, other situations, such as pre-hospital trauma care, should be avoided by HCWs restricted from performing EPPs, as they could also result in the exposure of the patient's open tissues to the blood of the worker. The definition of EPPs given above embraces a wide range of procedures in which there may be very different levels of risk of bleed-back. A risk-based categorisation of clinical procedures has been developed, including procedures where there is negligible risk of bleed-back (non-EPP) and three categories of EPPs with increasing risk of bleedback. Please refer to the definitions and examples of three categories of EPPs in Emergency Healthcare Workers, Exposure Prone Procedures (EPPs) and the Exposure Prone Environment.
