Flagpole safety in Germany: wind, liability and work at height
Published Written by Flagpole Guides
This page is an English translation of the German original. Where the two versions differ, the German text is the original.
A flagpole is a slender, tall structure that has to withstand wind and weather for years. If it breaks or a part comes loose, it can injure people and damage houses, cars or fences. Germany has no specific rule for flagpoles, but several general rules apply: building regulations, liability law under the Civil Code (BGB) and, for employers, occupational safety.
What building law requires
Even a flagpole exempt from the permit procedure is a structure. Under the Model Building Code, on which the state building codes are based:
- Section 3 MBO: installations are to be arranged, built, altered and maintained so that public safety and order, in particular life and health, are not endangered.
- Section 12 MBO: every structure must be stable as a whole and in its individual parts. The stability of other installations and the ground of neighbouring plots must not be endangered.
The building control authority can take action against installations that do not meet these requirements, even if they needed no building permit.
Wind and wind zones
Wind is the greatest load, and the flag provides most of the exposed area. Wind pressure rises with the square of the wind speed. For design, Germany applies DIN EN 1991-1-4 with the German National Annex, which divides the country into four wind zones. The German Institute for Building Technology publishes a table showing which municipality lies in which zone. Coastal regions and exposed high ground are subject to higher loads than inland areas.
- Manufacturer’s specifications: many manufacturers state which wind zone and which maximum flag size a pole is designed for.
- Smaller flag in a storm: a smaller flag catches less wind and relieves the pole and foundation.
- Severe weather warnings: the German Weather Service (DWD) publishes official warnings for every municipality. Before severe storms it is common to take the flag down or to lay a tilting pole down.
Liability under section 836 BGB
Section 836 BGB is particularly important for flagpoles. If a person is injured or property is damaged by the collapse of a structure connected to a property or by the detachment of parts, the possessor of the property is liable if the collapse or detachment results from faulty construction or inadequate maintenance. The duty to compensate does not apply if they exercised the care required in everyday life to avert the danger. A former possessor remains liable for up to one year after their possession ends.
General liability under section 823 BGB also applies. Whether a liability or buildings insurance policy covers such damage depends on the particular contract. Regular inspections and their documentation can help to show the care taken if damage occurs. More in the guide to flagpole maintenance.
Fall zone and location
A breaking pole can reach roughly as far as it is tall. Paths, play areas, parking spaces, buildings and neighbouring plots within this zone are affected, including during erection and lowering. More in the guide to flagpole installation.
Electricity and lines
- Overhead lines: aluminium and steel poles conduct electricity. Glass-fibre reinforced plastic can also become conductive when wet or dirty. This applies especially when raising and lowering the pole, as it swings out a long way.
- Underground lines: network operators provide information on lines before digging for the foundation.
- Lighting: under section 13 of the Low Voltage Connection Ordinance, apart from the network operator, only a registered installation company may install, extend or alter the electrical installation behind the house connection fuse.
Work at height
The greatest risk arises when something has to be done at the top of the pole: a snapped line, a jammed pulley, a stuck pole head.
- Not a point for ladders: DGUV Information 208-016 on the use of ladders expressly names poles and posts as unsafe points to lean ladders against.
- Tilting pole: a pole that can be laid down makes work on the pole head possible from the ground.
- Aerial work platform or specialist firm: for fixed, tall poles, aerial work platforms or specialist flagpole service firms are common.
- Employers: for employees, the Occupational Safety and Health Act and the Industrial Safety Regulation apply; the DGUV information explains when ladders are permitted as a workplace at all.
Common checkpoints
| What | When many check it |
|---|---|
| Cracks, dents, leaning | Spring and autumn |
| Bolts on the tilting device and foundation | Once a year |
| Line, pulley, snap hooks, pole head | Once a year |
| The whole pole | After severe storms |
A pole that leans, shows cracks at the base or moves in the foundation may be damaged. More in the guides to flagpole maintenance and flagpole repair.
Frequently asked questions
Who is liable if a flagpole falls over in Germany?
Under section 836 BGB, the possessor of the property is liable for damage caused by the collapse of a structure connected to the property or the detachment of parts, if this results from faulty construction or inadequate maintenance. The duty to compensate does not apply if they exercised the care required in everyday life.
May a ladder be leaned against a flagpole?
DGUV Information 208-016 on the use of ladders expressly names poles and posts as unsafe points to lean lean-to, extension and multi-purpose ladders against. The DGUV information is aimed at employers, but describes a risk that also exists in a private garden.
Is there a standard for flagpoles in Germany?
For design against wind, Germany uses DIN EN 1991-1-4 with its National Annex, which divides the country into four wind zones. In addition, the general requirements of the state building codes apply, under which every structure has to be stable.
When is the flag taken down in a storm?
There is no rule. Many manufacturers state a wind speed up to which the pole and flag are designed. The German Weather Service publishes official severe weather warnings for every municipality.
