This regulation requires hospitals to test and maintain electrical receptacles at patient bed locations and anesthesia administration areas, including post-installation testing and interval-based retesting based on performance data. Line isolation monitors (LIMs), if present, must be tested monthly (or annually if self-testing) and after any electrical system repairs or renovations. Facilities must maintain records of all tests, repairs, and modifications, including date, location, and results. This is a life-safety/electrical systems maintenance requirement applicable to hospital settings.
View official sourceK914 Electrical Systems – Maintenance and Testing Hospital-grade receptacles at patient bed locations and where deep sedation or general anesthesia is administered, are tested after initial installation, replacement or servicing. Additional testing is performed at intervals defined by documented performance data. Receptacles not listed as hospital-grade at these locations are tested at intervals not exceeding 12 months. Line isolation monitors (LIM), if installed, are tested at intervals of ≤ 1 month by actuating the LIM test switch per 6.3.2.6.3.6, which activates both visual and audible alarm. For LIM circuits with automated self-testing, this manual test is performed at intervals ≤ 12 months. LIM circuits are tested per 6.3.3.3.2 after any repair or renovation to the electric distribution system. Records are maintained o f required tests and associated repairs or modifications, containing date, room or area tested, and results. 6.3.4 (NFPA 99)
