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 four 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 and readily identifiable. Minimizing the possibility of damage of the emergency power source is a design consideration for new installations.

Observations:
Name: CLASS C ASF - Component: 01 - Tag: 0918
Based on document review and interview, it was determined the facility failed to maintain the emergency generator, affecting the entire facility.
Findings include:
Document review on May 15, 2024, at 10:00 a.m., revealed the March 5, 2024, Annual Fuel Quality Report indicated high particulate contamination. Proof of corrective action was not available at the time of survey.
Exit Interview with the Administrator and Facilities Manager on May 15, 2024, at 11:00 a.m., confirmed the fuel quality deficiency.
| | Plan of Correction - To be completed: 06/15/2024
Fuel polishing will be conducted on 06/06/24 and fuel will be re-tested once polishing has been completed.
Assuming we have a clean result of the fuel following the polishing, fuel testing will resume on its previous annual schedule next occurring on 03/2025.
Any deficiencies found in the fuel will result in a temporary generator being utilized until fuel issue is rectified.
Generator will be tested weekly as per NFPA 110 requirements. Results will be reviewed by the EOC Committee for a period of 3 months of 100% compliance.
Deficiencies and corrective actions will be reported annually to the EOC Committee.
