Fire Safety Device (PBZ) Inspections: What Must a Building Operator Check?
A fire extinguisher in the hallway and a fire hydrant behind a glass door are not the only fire safety devices (PBZ) a building operator must inspect regularly. Czech fire prevention regulations recognize six distinct types — alongside extinguishers and hydrants, also fire dampers, fire door assemblies, fire-stop penetration seals, and emergency lighting. An operator of offices, retail units, or warehouse facilities who has only two or three of these covered and overlooks the rest is, in reality, meeting only part of the legal requirements — and that is exactly the gap a Fire Rescue Service inspection tends to uncover.
The basic legal framework is Act No. 133/1985 Coll., on fire protection, and its implementing Decree No. 246/2001 Coll., on fire prevention, which requires regular functional inspections for both fire protection equipment and fire safety devices. Which specific PBZ your building must have, and to what extent, is set out in the building’s fire safety design and project documentation — it varies by use, floor area, and fire risk, whether the property is an office building, a retail unit, a studio, or a warehouse hall.
If you first need to clarify the general terminology, see our articles on inspection vs. review vs. expert examination or who is responsible for inspections at a company — this article focuses on what falls under the term PBZ and what is actually checked for each type.
Six types of PBZ recognized by law
| PBZ type | What it is in practice |
| Fire extinguishers | Portable or wheeled fire protection equipment for initial intervention when a fire breaks out, operable by essentially anyone in the building. |
| Internal hydrants and hose systems | Part of the internal fire water supply connected to a water source, used for initial and follow-up intervention on a larger scale than an extinguisher. |
| Fire dampers | A fire-separating element inside ventilation ductwork that closes automatically in the event of fire, preventing fire and smoke from spreading between fire compartments. |
| Fire door assemblies | Fire-rated doors, gates, or windows that must close reliably and completely in a fire, usually via a self-closing device. |
| Fire-stop penetration seals | Sealing at points where cables, wiring, or piping pass through a fire-separating wall or ceiling, so fire and smoke cannot spread through the opening. |
| Emergency (panic) lighting | Backup lighting for escape routes and signage that switches on automatically during a power outage, enabling safe evacuation of the building. |
What each inspection actually checks
| PBZ type | What the inspection verifies |
| Fire extinguisher | Seal and pressure gauge integrity, label condition and legibility, charge weight, mechanical damage to the cylinder, accessibility and visible placement. |
| Internal hydrant / hose system | Valve and nozzle function, hose and reel condition, water flow and pressure, periodic pressure testing of the hose. |
| Fire damper | Functional activation and complete closure (manually and via the fire alarm control system), actuator and sensor condition, seal tightness when closed, entry in the fire damper logbook. |
| Fire door assembly | Closing and sealing of the leaf against the frame, function of the self-closer and any door coordinators, integrity of the surface and seals, legibility of the fire-rating label, clear space for operation. |
| Fire-stop penetration seal | Integrity of the sealing material or system around the penetration, conformity with the certified installation, absence of additional cables or pipes routed through without re-sealing. |
| Emergency lighting | Functional test of switchover to emergency mode, duration of illumination against the rated time, condition and visibility of exit signage and fixtures, function of the central power source or batteries. |
How often inspections are required
Decree No. 246/2001 Coll. sets a general baseline of at least once a year for functional inspections of fire safety devices, unless the manufacturer, project documentation, or a fire risk assessment specifies a shorter interval. This baseline applies across all six types — what differs are supplementary tasks with their own cycle, such as hose pressure testing. An orientational overview:
| Device / task | Orientational interval |
| Fire extinguisher — functional inspection | Once a year (and immediately after any use) |
| Internal hydrant — functional inspection | Once a year |
| Hydrant hose — pressure test | Once every 5 years |
| Fire damper — functional check | Once a year |
| Fire door assembly — functional check | Once a year (more often for higher-risk facilities) |
| Fire-stop seal — integrity check | Once a year |
| Emergency lighting — functional test | Once a year (ideally supplemented by shorter functional checks) |
| Note: These intervals are the legal minimum, not recommended practice. The specific interval for your building may be shortened by the equipment manufacturer’s instructions, the building’s fire safety design, or a fire risk assessment — and during a Fire Rescue Service inspection, that specific interval takes precedence over the general table value. |
Who is authorized to perform the inspection
The decree refers generally to an “authorized person” — in practice, a fire protection technician or a person professionally qualified in fire protection. For fire extinguishers, manufacturer authorization for the specific charge type is often also required; for fire dampers, fire door assemblies, and fire-stop seals, training or authorization from the specific system’s manufacturer is often necessary, since the inspection procedure varies by construction. Before booking an inspection, it is worth verifying the technician’s authorization and scope of qualification — especially for dampers connected to an electronic fire alarm system (EPS).
What happens if a PBZ type is missing or fails inspection
Operating a building without valid inspections of fire safety devices is a breach of the operator’s obligations under Act No. 133/1985 Coll., with three main consequences in practice:
• during a Fire Rescue Service inspection, a legal entity or self-employed person faces a fine, significantly higher for facilities with elevated fire risk than for ordinary operations,
• in the event of a claim — particularly a fire — the insurer may reduce or fully deny payout if a device lacked a valid inspection,
• a non-functional extinguisher, a leaking door assembly, a compromised fire-stop seal, or emergency lighting that fails to switch on directly endangers people in the building and neighboring fire compartments — so this is primarily a safety risk, with sanctions only a secondary consequence.
Checklist: Do You Have All Six PBZ Types Under Control?
☐ An overview of all PBZ types in the building
You know how many fire extinguishers, hydrants, fire dampers, door assemblies, and fire-stop seals are in the building and exactly where they are located.
☐ Current labels and inspection records
Every device has a legible label showing the date of the last and next inspection.
☐ Fire damper logbook maintained and current
Records of functional tests match the inspections actually carried out.
☐ Fire door assemblies and fire-stop seals are not overlooked
Fire-rated doors are not wedged open, and penetrations are not modified afterward without re-sealing.
☐ Emergency lighting still functional after a year in service
The annual functional test for the full rated illumination time has been performed, not just a brief switch-on.
☐ Unobstructed access to all devices
Fire extinguishers, hydrant cabinets, and escape routes are not blocked by furniture, pallets, or goods.
☐ Verified technician qualification
The person performing the inspection is authorized for that specific device type, with manufacturer training where required for dampers, door assemblies, or fire-stop seals.
FAQ
Must every office or retail unit have all six types of PBZ?
Not necessarily — which specific PBZ a building must have is set out in the fire safety design based on floor area, fire load, and intended use. A small office may not need fire dampers or fire-stop seals if none are specified in the project, but fire extinguishers and emergency lighting are almost always required.
Is it enough to inspect only the visible PBZ, such as extinguishers and hydrants?
No. Fire dampers in ventilation ducts, door assemblies, and fire-stop seals are often hidden above suspended ceilings or in service shafts, but they are subject to inspection just like visible equipment — and a Fire Rescue Service inspection checks all PBZ listed in the building’s documentation, not only what is in plain sight.
Who maintains the fire damper logbook and similar records for fire-stop seals and door assemblies?
The building operator is responsible for maintaining the records, but in practice they are usually created and updated by the technician who installs or inspects the equipment — the operator should ensure the records exist and are kept up to date for every PBZ type, not just fire dampers.
Can we skip the hydrant hose pressure test if the hose looks fine visually?
No. Visual condition does not demonstrate the material’s strength at maximum operating pressure — the pressure test is a separate requirement, independent of appearance, with its own cycle (typically once every 5 years).
Does one inspection deadline apply to the whole building, or does each PBZ type have its own?
Each type has its own, and deadlines can even vary within a single type depending on manufacturer or location — aligning all inspections to a single date is convenient organizationally, but it is not a legal requirement.
Six types of PBZ, one record in the Client Portal
Fire extinguishers, hydrants, dampers, door assemblies, fire-stop seals, and emergency lighting each have different technical requirements and deadlines — but in practice that doesn’t have to mean managing their records and scheduling in a fragmented way. INTECHI provides inspections for all of these PBZ types as a single, comprehensive service and manages them in the INTECHI Client Portal:
• Deadline tracking — the system automatically tracks the inspection deadline for every fire extinguisher, hydrant, damper, door assembly, fire-stop seal, and emergency light individually, and sends an email alert well in advance so none of them lapses unnoticed.
• Equipment record matching — every PBZ, from an extinguisher to a fire-stop seal, has its own record with a full inspection history, not just a general entry for the whole building, so you can look up the status of a specific unit in a few clicks.
• Automated follow-up steps — if an inspection finds a defect (a leaking damper, a damaged hose, a non-functional self-closer), you submit a repair request immediately, and INTECHI’s dispatch schedules the fix along with the follow-up verification.
• CAD drawing import — you upload the layout of every PBZ type directly into the system and link it to the specific equipment records.
• Documentation processing and archiving — inspection reports, the fire damper logbook, and hose pressure test records are all digital and in one place, ready to retrieve during a Fire Rescue Service inspection or for insurance purposes.
How INTECHI Handles This
INTECHI provides inspections for all six types of fire safety devices as part of comprehensive technical building management — from offices to retail units, studios, and warehouse facilities — and manages every inspection and follow-up repair in the Client Portal, giving the building operator an immediate overview of the status of every device in one place.
