NFPA 780-engineered protection for life-safety systems and patient data
A hospital cannot delay a lightning assessment until the forecast clears. A single strike or nearby surge doesn’t disrupt a building — it disrupts patient care, life-safety systems, and the imaging and monitoring equipment that clinicians depend on in minutes. In a healthcare facility, the stakes aren’t uptime for revenue. They’re patient safety.
All South Lightning Protection designs and installs engineered lightning protection and surge suppression systems built specifically for hospitals, clinics, ambulatory surgical centers, and healthcare facilities across Florida. We protect what matters: emergency power, life-safety systems, networked patient monitoring, EHR servers, imaging equipment (MRI, CT), telemetry and nurse-call systems, elevators, and the electrical service feeding all of it. Every system is purpose-designed to NFPA 780, NFPA 99 (Health Care Facilities Code), and UL 96A — not pulled off a shelf. We have done this, and only this, for 40 years.
Florida is the lightning capital of the United States, with roughly 1.4 million cloud-to-ground strikes a year. If your hospital sits here, the question isn’t whether it gets exposed. It’s whether it’s protected when it does — and whether your staff has the documentation to prove it.
A hospital’s redundancy systems, backup power, redundant networks, and failover systems protect against power loss. They do not stop a lightning transient. That’s a separate engineering discipline, and it’s ours. Here’s what is actually at risk when a strike or nearby surge reaches an unprotected healthcare facility:
Most healthcare facilities believe they’re covered because they have backup power, UPS systems, and medical-grade surge strips. Those protect against some things, but almost nothing about a lightning event. Use the layered model below to audit your own facility — top to bottom, the strike enters the same way every time, and a gap at any layer is the gap that gets used. Each layer lists what it does, the failure mode when it’s missing, and the standard it maps to.
| Layer | What it does | Failure mode if missing / undersized | Maps to |
|---|---|---|---|
| 1. Structural strike termination | Intercepts a direct strike at air terminals and routes it to earth via down conductors, around the building. | Strike attaches to the roof, HVAC, or structural steel and arcs internally looking for ground through your equipment. | NFPA 780 (Rolling Sphere) |
| 2. Service-entrance SPD (Type 1) | Clamps the large conducted surge on the utility feed and generator connection before it enters the facility. | Full service-entrance transient reaches distribution gear and everything downstream — life-safety systems, imaging, EHR servers. | UL 1449 / NFPA 780 Ch. 4 |
| 3. Distribution SPD (Type 2) | Catches residual surge at panels feeding critical loads (OR, ICU, imaging, pharmacy). | Let-through voltage from Layer 2 still exceeds what medical equipment survives. | UL 1449 |
| 4. Data/telemetry/signal line protection | Protects network, nurse-call, telemetry, medical gas alarm, and laboratory LIS data entering the facility or crossing between buildings. | Transient bypasses all power-side protection — enters on data lines. Corrupts EHR, disables nurse-call, and crashes telemetry monitors. | NFPA 780 / IEC 62305 |
| 5. Grounding & equipotential bonding | Ties all systems (structural, water, medical gas, lightning protection, power, equipment racks) to a common reference so nothing floats at a different potential during a strike. | Unequal grounds arc between each other — the classic source of “unexplained” imaging and monitor failures in healthcare. | NFPA 780 / NEC Art. 250 / NFPA 99 Ch. 5 |
| 6. Point-of-use protection | Final trim at imaging, pharmacy, ventilators, infusion pumps, monitors — the last layer before the device itself. | On its own, it’s asked to absorb a service-entrance event it was never rated for. Imaging and monitor manufacturers often specify downstream protection, assuming upstream layers exist. | UL 1449 (Type 3) |
| 7. Inspection & recertification cycle | Confirms the whole chain is intact after changes, additions, strikes, and facility renovations. Joint Commission readiness. | Documentation lapses; a modified or expanded facility no longer matches its certified drawings. | UL 96A / NFPA 99 Ch. 5 |
Healthcare buyers require more documentation than most sectors. Every All South healthcare system is engineered and installed to the standards below, and delivered with sealed, permit-ready drawings, a documented submittal package, and Joint Commission readiness report.
| Standard | What it covers |
|---|---|
| NFPA 780 | Installation of lightning protection systems |
| NFPA 99 | Health Care Facilities Code (electrical, power, life-safety, medical gas) |
| NFPA 110 | Emergency and Standby Power Systems (emergency generator protection context) |
| UL 96A | Master Label requirements and inspection for LP systems |
| IEC 62305 | International lightning protection standard |
| LPI-175 / LPI-177 | Lightning Protection Institute design and installation certification |
| NEC Art. 250 | Grounding and bonding requirements |
Is lightning protection required by code for hospitals?
NFPA 780 is the governing standard for lightning protection system design and installation, and NFPA 99 explicitly addresses healthcare facilities’ life-safety electrical needs. Most jurisdictions, accrediting bodies, insurers, and healthcare networks require documented, code-compliant protection on critical facilities. We design every system to be permit-ready, fully documented, and audit-ready for your AHJ, Joint Commission, and carrier.
Does lightning have to hit the building to damage hospital equipment?
No. Most lightning-related healthcare equipment damage comes from surges, not direct strikes. A strike up to a quarter-mile away can induce a transient that travels into the facility on power lines, data lines, or medical gas alarm lines. That’s why surge protection and signal-line protection matter as much as the structural system.
Will installation disrupt patient care or infection-control zones?
No. The work is planned entirely around your operations. Structural work is external (roof, down conductors, grounding). Service-entrance and panel work is scheduled during off-hours or planned maintenance windows. Signal-line and bonding work uses existing conduit routes. You get a detailed implementation plan with the quote, and we work with your facilities team to coordinate around patient care and infection-control requirements.
Does lightning damage imaging equipment even without a direct strike?
Yes. MRI, CT, X-ray, ultrasound, and nuclear medicine equipment are sensitive to transient overvoltage from nearby strikes. A surge can degrade magnets, damage gradient coils, corrupt imaging data, or disable the system entirely. Even a “near miss” strike miles away can induce a surge on the power and signal lines feeding imaging equipment. Proper upstream surge protection and point-of-use protection are critical for imaging availability.
Do you protect data and telemetry lines, not just power?
Yes. This is a must in healthcare. Nurse-call systems, telemetry monitors, continuous cardiac monitoring, laboratory LIS data, pharmacy network systems, and EHR server connections all run on copper data lines vulnerable to surge entry. Most healthcare surges that damage equipment come in on the data side, not the power side. We protect both.
Do you provide the documentation Joint Commission and our insurer require?
Yes. You receive sealed engineering drawings, a permit-ready submittal package, UL 96A certification, a full specifications document, and a Joint Commission readiness report. Recertification on schedule keeps your documentation audit-ready as your facility changes.
