Isolated Power System Requirements

• 3.3.171 – "Wet Procedure Locations. The area in a patient care space where a procedure is performed that is normally subject to wet conditions while patients are present, including standing fluids on the floor or drenching of the work area, either of which condition is intimate to the patient or staff."
• 6.3.2.2.8.4 – "Operating rooms shall be considered to be a wet procedure location unless a risk assessment conducted by the health care governing body determines otherwise."
• 6.3.2.2.8.1 – "Wet procedure locations shall be provided with special protection against electric shock."

In addition to Operating Rooms, "wet procedures" are often performed in other Category 1 (Critical Care) Areas. Such as Emergency Department, Labor and Delivery, Cath Lab, Intensive Care Unit, and Post-Op areas.* These areas may pose an elevated safety risk of electrical shock to patients or caregivers due to contact with conductive fluids such as antiseptics, irrigation, and body fluids. The Isolated Power NFPA 99 System safely limits the first-fault ground current without interrupting the supply of power to critical equipment. GFCI protection is not recommended on any critical load that cannot have an interruption of power while in use.

* In circumstances where special options are needed for interoperative magnetic resonance imaging (iMRI) surgical suites, PG LifeLink's SafeDetec line isolation monitors can accomodate this requirement. Contact PG LifeLink sales and application engineering for more information.
