Electrical Systems - Essential Electric System Maintenance and Testing The generator or other alternate power source and associated equipment is capable of supplying service within 10 seconds. If the 10-second criterion is not met during the monthly test, a process shall be provided to annually confirm this capability for the life safety and critical branches. Maintenance and testing of the generator and transfer switches are performed in accordance with NFPA 110. Generator sets are inspected weekly, exercised under load 30 minutes 12 times a year in 20-40 day intervals, and exercised once every 36 months for 4 continuous hours. Scheduled test under load conditions include a complete simulated cold start and automatic or manual transfer of all EES loads, and are conducted by competent personnel. Maintenance and testing of stored energy power sources (Type 3 EES) are in accordance with NFPA 111. Main and feeder circuit breakers are inspected annually, and a program for periodically exercising the components is established according to manufacturer requirements. Written records of maintenance and testing are maintained and readily available. EES electrical panels and circuits are marked, readily identifiable, and separate from normal power circuits. Minimizing the possibility of damage of the emergency power source is a design consideration for new installations. 6.4.4, 6.5.4, 6.6.4 (NFPA 99), NFPA 110, NFPA 111, 700.10 (NFPA 70)

Observations: Name: MAIN BUILDING 01 - Component: 01 - Tag: 0918
Based on documentation review and interview, it was determined the facility failed to maintain the generator set in several instances, affecting four of four floors.
Findings include:
1. Observation on July 8, 2024, between 12:20 p.m., and 12:25 p.m., revealed the following:
a. 12:20 p.m., the facility lacked a natural gas reliability letter. b. 12:21 p.m., the facility lacked recorded, weekly, generator set, visual inspection documentation. c. 12:22 p.m., the facility lacked recorded, weekly, generator set, battery Electrolyte or Battery Voltage readings. d. 12:25 p.m., the facility lacked recorded, monthly, generator set, load testing data. e. 12:29 p.m., the generator set emergency stop button was located within the same enclosure (room) as the generator set.
Exit interview with the Facility Administrator on July 8, 2024, between 12:45 p.m., and 1:05 p.m., confirmed the generator set deficiencies.
| | Plan of Correction - To be completed: 08/30/2024
The facility will obtain a natural gas reliability letter from the supplier. Weekly generator set will include visual inspection documentation, battery voltage readings and load testing data. The facility will have the emergency stop button relocated out of the generator room.
