Hospital emergency power systems are tested more frequently than almost any other building system — and yet generator failures during actual power outages remain a leading cause of life-safety incidents in healthcare facilities. The problem is rarely equipment quality. It is incomplete testing records, missed load bank cycles, and transfer switch tests that were done but never properly documented for the next CMS or Joint Commission surveyor who asks. OxMaint puts every generator PM, test log, load bank record, and escalation in one place — so your emergency power system is always survey-ready, not just operationally ready.

NFPA 110 and NFPA 99 Chapter 7 require documented monthly runs, annual load tests, and complete transfer switch records. Keep every test log, load bank result, and escalation visible and audit-ready in OxMaint.
Why Hospitals Receive Generator Citations Despite Conducting Tests
The Joint Commission's Environment of Care standard EC.02.05.07 requires hospitals to maintain emergency power systems with documented testing at specified intervals. Analysis of survey findings consistently shows that the most common citation pattern is not a generator that failed to start — it is a test log that was incomplete, a load bank report that arrived from the contractor and was never filed to the asset record, or a transfer switch test that was recorded on paper but cannot be retrieved two years later during a follow-up survey.

Every Test. Every Transfer. Every Escalation. Logged.
OxMaint auto-schedules every NFPA 110 task, logs test parameters in the field, routes failures to your team, and keeps a complete audit trail — from the monthly 30-minute run to the annual load bank test.
What OxMaint Does for Generator Maintenance
Register your generator assets once and OxMaint creates the full NFPA 110 test schedule automatically — weekly visual checks, monthly runs, quarterly battery tests, and annual load banks — all assigned to the correct team with due dates.
Technicians record voltage, frequency, start time, run duration, oil pressure, and coolant temperature directly on a mobile device next to the generator. No paper, no transcription errors, no back-filling from memory at the end of a shift.
Annual load bank tests and fuel quality sampling are typically performed by contractors. OxMaint provides a direct upload path so contractor-issued test reports are stored against the generator asset record — not lost in an email inbox.
If a monthly run reveals low oil pressure, abnormal voltage, or a generator that failed to start, OxMaint immediately opens a priority work order and routes it to your escalation contacts — with the test data already attached.
Each automatic transfer switch is tracked as a separate asset with its own monthly test schedule. Transfer time, re-transfer time, and switch condition are logged per event — giving surveyors a complete transfer history for every ATS in the facility.
NFPA 110 requires a minimum 72-hour fuel supply for Type 1 EPS in healthcare. OxMaint tracks fuel inventory readings against the rated consumption of each generator and alerts your team when reserves fall below the required threshold.
What Facilities Engineers Say About EPSS Compliance
Hospital Generator Maintenance Software — FAQ
What does NFPA 110 require for hospital generator testing?
NFPA 110 requires weekly visual inspections of standby generators, monthly operational tests of at least 30 minutes duration with recorded parameters (voltage, frequency, oil pressure, coolant temperature), quarterly battery load tests, and an annual full load bank test at rated kilowatt capacity for a minimum of two hours. For Type 1 EPS systems in healthcare facilities, transfer switch operation must also be tested monthly with transfer time documented. All test results must be retained in a retrievable record for surveyor review. OxMaint manages the complete schedule automatically.
How does OxMaint handle load bank tests performed by outside contractors?
When your contracted load bank testing company completes the annual test, the resulting report needs to be filed against the specific generator asset in your compliance system — not emailed and forgotten. OxMaint allows your facilities team to attach contractor-issued PDF reports directly to the generator asset record, with the test date, test parameters, and pass/fail status logged alongside the report. If the contractor does not provide the report within a specified window, OxMaint flags the asset as pending documentation — preventing the common scenario where a test was completed but the record cannot be produced at survey time. See how this works in a live demo.
What is the difference between NFPA 99 Chapter 7 and NFPA 110 requirements?
NFPA 99 Chapter 7 establishes the healthcare-specific requirements for emergency power supply systems — including the 10-second transfer time requirement for life safety and critical care branches, the 72-hour fuel supply minimum, and the requirement for separation of life safety and critical branches. NFPA 110 provides the testing, maintenance, and installation standards for the generator equipment itself. Healthcare facilities must comply with both: NFPA 99 Chapter 7 defines what the system must be capable of, and NFPA 110 defines how frequently and rigorously it must be tested. OxMaint pre-loads both standard's requirements into your testing schedule.
Can OxMaint track multiple generators and transfer switches across a large hospital campus?
Yes. OxMaint supports any number of generator assets, each registered as a distinct unit with its own asset profile, test schedule, and compliance history. For campuses with multiple buildings, generators and transfer switches are organized by building and floor — so your engineering team has an instant view of which assets have completed testing this month and which have open items. Cross-asset reporting gives your Director of Engineering a single dashboard view of EPSS compliance across the entire facility. Start a free trial to register your generator assets.
