How to Inspect a Hospital Battery Backup System Under NFPA 855

NFPA 855 inspections are unlike any other inspection in the fire protection world. There's no prescriptive list of "check these 12 items annually" the way NFPA 25 or NFPA 72 provides. Instead, the standard creates a framework centered on documentation verification and physical condition assessment — the inspector's job is to verify that required documentation exists, is current, and that physical safety systems are operational.

This guide walks through the inspection checklist for a hospital energy storage system (ESS) — specifically the UPS and battery backup systems that are most commonly found in healthcare facilities.

Before the Inspection: What to Know Going In

Before you walk into the mechanical room, you need three things:

• The ESS technology type — lithium-ion is most common in hospitals, but lead-acid and nickel-based systems exist in older facilities. The technology type determines which specific requirements of Chapter 9 apply.
• The aggregate stored energy capacity in kWh — this determines whether NFPA 855 applies at all (20 kWh threshold for Li-ion) and which installation requirements are triggered by capacity.
• The manufacturer's O&M documentation — NFPA 855 defers inspection frequency to the manufacturer. You need to know what the manufacturer requires before you can assess compliance.

If the facility doesn't have the manufacturer's O&M documentation on site, that's a finding before you've touched anything else.

The Inspection Checklist

What follows is organized by the inspection sections in NFPA 855, built from the 2026 edition.

What Goes on the Report Cover

The NFPA 855 inspection report should document — at minimum — on the cover page:

• Facility name and address
• ESS technology type (Li-ion, Lead-Acid, etc.)
• Aggregate stored energy capacity in kWh
• UL 9540 listing status (listed / not listed)
• HMA (Hazard Mitigation Analysis) on file (yes / no / N/A)
• Inspection date and inspector name/license
• Overall compliance status

The Frequency Question

Inspectors new to NFPA 855 often ask: how often should I inspect? The standard's answer is: per the manufacturer's O&M documentation. There is no prescriptive annual/quarterly/monthly schedule in NFPA 855 itself — it defers to the manufacturer.

In practice, most hospitals schedule NFPA 855 inspections annually in coordination with their other annual fire protection inspections. Some manufacturers specify more frequent checks for certain components. The inspector should note the manufacturer-specified inspection frequency in the report and confirm that the schedule is being followed.

Documentation Is the Inspection

More than any other NFPA standard, 855 compliance is primarily demonstrated through documentation. An AHJ or Joint Commission surveyor reviewing an ESS installation will ask to see the O&M documentation, the maintenance records, the testing records, and the SDS. The physical condition inspection confirms that safety systems are in place and operational — but the paper trail is what establishes ongoing compliance.

This means the inspection report isn't just a checklist — it's a record of which documents exist, whether they're current, and who reviewed them. That's a different documentation discipline than NFPA 25 or NFPA 72, and it's one more reason why inspection software that supports 855 is valuable: the structured checklist ensures no documentation gap goes unrecorded.
