Central overview table
This table is the core of the article — listing every structural fire-protection element with duty, interval, legal basis and required qualification. Save it, print it, hand it out — the table covers 95 % of the questions.
| Element | Duty | Interval | Basis | Who may inspect |
|---|---|---|---|---|
| Fire doors | Maintenance + inspection | annually | DIN 31051, DIN 14677 | Specialist firm with qualified knowledge |
| Fire gates | Maintenance + inspection | annually | DIN 31051, BetrSichV, DIN 14677 | Specialist firm with qualified knowledge |
| Hold-open devices | Function check | monthly | DIN 14677 | Operator (trained) |
| Hold-open devices | Qualified inspection | annually | DIN 14677 | Specialist firm with qualified knowledge |
| Smoke detector hold-open | Replacement | every 5–8 years | Manufacturer | Specialist firm |
| Cable seals | Visual check | regularly | MLAR, LAR | Operator / specialist firm |
| Pipe seals | Visual check | regularly | MLAR, LAR | Operator / specialist firm |
| Fire-protection cladding | Visual check | during walk-through | — | Operator / specialist firm |
| Inspection openings | Visual check | during maintenance | — | Operator / specialist firm |
| Overall: fire-safety audit | Official control | every 3–5 years | State law | Fire brigade / authority |
Fire doors in detail
Doors are the most common position — and by some margin the most common source of defects in fire-safety audits. Annual maintenance is mandatory, as is the qualified knowledge of the inspector.
- What's checked: closing behaviour, seals, hardware, frame, glazing and approval label
- Who may inspect: specialist firm with qualified knowledge per DIN 14677
- Documentation: inspection protocol with defect levels A / B / C, entry in the inspection log
- When in doubt: a service contract — automatic scheduling removes the burden of monitoring
Fire gates
Gates are more complex than doors — drive, control, safety devices. In high-frequency operations (logistics) shorter intervals than annually are often necessary.
- What's checked: closing behaviour, drive, control, safety devices and seals
- Interval: annually, more often in high-frequency use
- Who may inspect: specialist firm with manufacturer qualification
Hold-open devices — two-tier inspection
Hold-open devices are a special case: two mandatory layers. Monthly the operator checks function (press the smoke-test button, the door must close); annually the qualified inspector comes.
- Monthly function check by trained operator (smoke test button)
- Annual qualified inspection by a specialist firm
- Smoke detector replacement every 5–8 years — depending on the manufacturer date
- Entry in the inspection log both monthly and annually
Penetration seals — the most common defect at audits
Penetration seals — cable, pipe, combination — have no explicit annual maintenance duty but must be checked regularly by visual inspection. By far the most common defect at fire-safety audits is a subsequently violated seal — a cable pulled through, the hole never properly resealed.
- No explicit annual maintenance duty, but visual inspection is mandatory
- Most common defect: subsequently violated seals (cables pulled through later)
- Recommendation: include the annual visual check together with the door maintenance
Cladding and enclosures
Fire-protection cladding for steel beams and ventilation ducts, enclosures for server rooms or machinery — visual check for damage suffices here. Important: always inspect after refurbishments or retrofits, because interventions often cause creeping damage.
Legal basis at a glance
The maintenance duty arises not from a single rule, but from several sources that together paint a clear picture:
- DIN 31051 — principles of maintenance
- DIN 14677 — qualified inspection of fire- / smoke-resisting closures
- Workplace Safety Ordinance (BetrSichV)
- ASR A1.7 — workplace technical rules
- Cable Installation Directive (MLAR), in NRW LAR — penetration seals
- State building codes — operator duties
- Manufacturer specifications — condition for keeping the approval
Who is liable?
The maintenance duty falls on the operator personally — under state building code and criminal law. Who that is depends on the constellation: owner, manager, management; in some cases also tenant or lessee (depending on contract).
On consequences of neglect: no scaremongering, but the reality is clear. Insurers refuse to pay in case of a claim if maintenance evidence is missing. Building-authority orders up to use prohibition are possible. On personal injury, criminal relevance is on the table.
- Owner (transferable on letting — check the contract!)
- Tenant / lessee (depending on contract design)
- Management (personal liability possible)
- Not the maintenance contractor for missed dates — unless explicitly agreed in the service contract
Documentation duty
Complete documentation is part of the maintenance duty — not reconstructable after the fact, but kept continuously in the inspection log. The effort is manageable; the benefit in case of dispute is enormous.
- Inspection protocols per position
- Inspection log or file for the entire property
- Photos before / during / after repairs
- Defect lists with remediation evidence
- Approval evidence and conformity declarations
- Retention over the entire useful life of the component
What happens at the fire-safety audit?
The fire-safety audit is official, controlling and can issue orders. The fire brigade checks samples but explicitly demands inspection protocols as evidence. Anyone who cannot produce maintenance documentation has a problem — even if the doors are technically fine.
- Fire brigade checks samples
- Inspection protocols are demanded — must be presented
- On defects: deadlines for remediation, possibly follow-up inspection
- On imminent danger: immediate use prohibition possible
A service contract is the simplest solution
The most reliable way to fulfil all maintenance duties is a service contract. Automatic scheduling, predictable cost, one contact for all maintenance — and the certainty that no date slips through.
- Automatic scheduling — no forgetting
- Predictable cost per door / gate / device per year
- Legally defensible documentation
- One contact for doors, gates, hold-open devices, penetration seals
- Repair priority outside the maintenance cycle
Common misconceptions
Four sentences we hear regularly in initial conversations — and why they don't hold.
- "We did fire protection at construction." — One-off doesn't suffice. Regular inspection is mandatory regardless of installation date.
- "Our caretaker handles it." — Only with documented training per DIN 14677. No qualified knowledge, no valid maintenance.
- "We've never had problems." — Liability exists regardless of incidents. In a claim event, complete evidence counts, not a clean track record.
- "Our insurer knows about it." — Insurance cover requires evidence. Without inspection protocols, the insurer will refuse to pay.
