Appendix O
HOSPITAL ELECTRICAL SAFETY
O-1. ELECTRICAL SAFETY TESTING FREQUENCY.
a. All medical equipment will be electrically safety tested prior to initial use and at least annually thereafter as per AR 40-61, Medical Logistics Policies.
b. Medical equipment will also be tested after repair or modification.
O-2. ELECTRICAL SAFETY TEST REQUIREMENTS.
a. All electrical safety tests will be performed in accordance with the most recent version of NFPA 99, Health Care Facilities Code.
b. Equipment that meets the manufacturer’s recommended standard and passes that standard will be considered safe, even if it does not meet the NFPA 99 standard.
c. Resistance Tests (appliance chassis to ground) must be performed before any Leakage Current Tests. The resistance level for conventional medical devices shall not exceed 0.50 ohms.
d. Chassis Leakage Current Tests for both fixed and portable medical equipment from frame to ground shall not exceed 5.0 ma (mill-amperes) or 300 (a (microamperes) respectively, with all grounds lifted.
e. All other pertinent electrical safety tests, to include Lead-to-Ground, Isolation, and Between-Leads are found in chapter 7 of NFPA 99 and must be performed when applicable (e.g. lead-to-ground for an EKG machine).
O-3. DOCUMENTATION OF ELECTRICAL SAFETY TESTING.
a. The scheduled DMLSS work order will serve as an approved record and fulfills the documentation requirement for all successful electrical safety testing. For an electrical safety that is unsuccessful use DA FORM 5621-R, Medical Equipment Electrical Safety or DA FORM 5622-R, Leakage Current Measurements. One is for general use and one is for EKGs. Instructions for filling out the forms are in chapter 2 of TB 38-750-2, Maintenance Management Procedures for Medical Equipment.
b. Line Isolation Monitors (LIM) will be tested IAW NFPA 99.
O-4. OTHER REQUIREMENTS.
a. The use of extension cords and plug adapters is not authorized on medical equipment unless manufactured with the piece of equipment. All other use is limited and will be permitted only as detailed in NFPA 99 (or later). For example, no appliance that draws at least 6 amperes of current can be connected to an extension cord. See TB MED 750-1, Operating Guide for Medical Equipment Maintenance and NFPA 99 for more technical and detailed information.
b. Familiarize yourself with emergency power systems here in the hospital. Pending approval, plug in any medical device requiring an uninterrupted power source to an emergency outlet which is color-coded red and marked “emergency power.”
c. The testing of systems that use a power cord, (e.g. Scope Tower) must also be tested in unison with all of the system components in addition to individual equipment test. The entire system tested together must meet standards stated in O-2 c & d.
