Equipment classes AK-A, AK-B, and AK-C according to DGUV 201-056: What they mean and how they are determined
Equipment classes EC-A, EC-B, and EC-C are the central planning tool of the revised DGUV Information 201-056 (September 2025). They define the level of protection required for a roof area – depending on how often the roof is accessed, what activities take place there, and which groups of people have access.
Why Equipment Classes Were Introduced
The previous version of DGUV 201-056 from 2015 essentially focused on individual anchor devices. This was sufficient for a time when flat roofs were rarely accessed and only by specialist personnel.
The reality has changed: PV systems, air conditioning units, green roofs, and roof terraces have turned many flat roofs into frequently used areas. At the same time, there is no single requirement that fits every type of use. The equipment classes create a clear, graded structure here.
Equipment Class EC-A: Highest Requirement
EC-A applies to roof areas with frequent use, many different people, or areas with public access. Typical examples include roof terraces, highly frequented flat roofs with multiple technical installations, and buildings with regular inspections by changing personnel.
Typical measures for EC-A: permanent, fixed railings and side protection systems, secured access routes and stairs, clearly defined and marked traffic routes, and regular inspection of all systems.
Equipment Class EC-B: Standard for Maintenance Roofs
EC-B applies to areas with regular use by specialist personnel – such as service technicians for PV systems, air conditioning units, or ventilation technology. This is currently the most common case for commercially used buildings.
Typical measures for EC-B: permanent or long-term temporary anchor devices, suitable roof access (secured attic ladder or stairs), protection concept with documented risk assessment, and instruction of all persons accessing the roof.
Equipment Class EC-C: Rare Use by Instructed Specialist Personnel
EC-C applies to roof areas that are accessed very rarely – for example, once a year for inspection or as needed for repairs. This applies exclusively to specialist personnel with full instruction and their own protection concept.
Typical measures for EC-C: mobile fall protection systems (e.g., anchors or temporary roof edge protection), PPE against falls from a height with a suitable anchor point, rescue concept, and complete documentation of protective measures.
How Is the Equipment Class Determined?
The classification results from a systematic assessment of the roof area based on: frequency of access, type of activities performed, group of people (specialist personnel, changing personnel, public), and structural conditions (fall height, roof shape, existing infrastructure).
Important: The classification is not optional. Anyone who classifies a roof with regular PV maintenance as EC-C, even though EC-B applies, is acting against the content of DGUV 201-056 – with corresponding liability risks in the event of damage.

Frequently Asked Questions
Does the equipment class apply to the entire roof or only to sub-areas?
The classification can vary for different areas of a roof surface – a heavily used area around an air conditioning unit may require EC-B, while a remote area of the same roof surface is classified as EC-C.
Do I have to retroactively adapt existing buildings?
The DGUV Information is not a legal obligation, but it is considered the state of the art. Those who do not adapt existing buildings risk liability consequences in the event of damage. An assessment and an adaptation plan are recommended.
Who is allowed to make the classification?Typically the building operator or an appointed specialist planner. The classification should be documented and justifiably reasoned.
