Fire Protection Maintenance Duties —
what, how often, by whom?

Structural fire-protection elements must be maintained — doors, gates and hold-open devices at least annually, penetration seals and cladding by regular visual inspection. The duty falls on the operator personally — neglect risks loss of insurance and personal liability.

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
03 —

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
04 —

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
05 —

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
08 —

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
09 —

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
11 —

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.
