What is a scaffold inspector (competent person)?
A scaffold inspector is a competent person (befähigte Person) who checks a scaffold after erection and before it is handed over for use. The aim is to confirm that the scaffold is structurally sound and complete so that workers can use it safely. The inspector documents the result and releases the scaffold with a scaffold tag (Gerüstkennzeichnung).
The legal anchor is the Betriebssicherheitsverordnung (BetrSichV, the German industrial safety ordinance), which requires work equipment to be inspected by a competent person before first use and after events affecting safety. The technical detail sits in TRBS 2121 Part 1 on the use of scaffolds, and the practical guidance comes from DGUV Information 201-011. The occasion for an inspection, and its depth, follow from the employer's risk assessment, the manufacturer's assembly instructions, and what the site actually looks like on the day.
Two things have to be kept apart. The inspection after erection or alteration belongs to the scaffold contractor, who evidences a safe scaffold to the user with an acceptance inspection report and marks it. An employer erecting a scaffold for its own workers must have it inspected by a competent person before first use under § 14 (1) BetrSichV. The scaffold user, the employer whose workers use it, owes something else: a visual check and, where needed, a function check for obvious defects under § 4 (5) sentence 3 BetrSichV, assigned under TRBS 2121 Part 1 number 4.3.3 to a qualified person, which is not the same as a competent person. After storms, longer standstills or modifications, inspection by a competent person under § 14 (3) BetrSichV applies again. The inspection follows the assembly instructions: anchoring, bracing, decking, side protection, access points, ground bearing, then whether the load class and width class match the planned work.
Competence requires suitable vocational training, professional experience and recent practical activity in scaffold work. The competent person needs sufficient knowledge of the relevant scaffold standards, such as the DIN EN 12810 and DIN EN 12811 series, and of the assembly instructions in use. The role is responsibility, not a transfer of the employer's duties: the employer appoints a genuinely competent person and, under § 14 (6) BetrSichV, gives that person no technical instructions on the inspection. What an inspecting authority queries is rarely the check but its trace: a tag without a date of the last inspection, no cover arranged for holiday or sickness.
Core duties of the scaffold inspector
- Inspect the scaffold after erection or alteration against the assembly instructions and TRBS 2121 Part 1
- Inspect a scaffold the employer erects for its own workers before first use under § 14 (1) BetrSichV
- Mark the scaffold under TRBS 2121 Part 1 number 4.2.9 with erector, scaffold type, load class, width class, any usage restriction, warnings, date of the last inspection
- Verify anchoring, bracing, decking, side protection, access and ground bearing
- Document the inspection result, defects found and the release decision
- Re-inspect after modifications requiring inspection and after exceptional events such as storms or long standstills under § 14 (3) BetrSichV
- Block or flag scaffolds that are incomplete or unsafe until rectified
- Confirm the load class and width class match the intended work
- Cooperate with the scaffold contractor and the user company on defect rectification
- Keep the inspection records available for the supervisory authority and the accident insurer
When is a scaffold inspector appointed?
The employer must have scaffolds inspected by a competent person under the Betriebssicherheitsverordnung before first use and after every event that may have affected their safety. The appointment of a competent person is therefore not optional wherever scaffolds are erected and used; it is the practical means of meeting the inspection duty.
Two roles have to be kept apart. For the inspection of the scaffold, TRBS 2121 Part 1 number 5.5 requires a competent person, who may be one of the scaffold contractor or one of the employer that makes the scaffold available to its workers. The visual check and function check before use are assigned by the scaffold user, under TRBS 2121 Part 1 number 4.3.3, to a qualified person, meaning someone the user entrusts with that task and who is qualified for it. The contractor's tag does not release the user: under number 4.2.9 the marking is a precondition for the visual check, not a substitute for it.
Competence is defined in § 2 (6) BetrSichV and detailed in TRBS 1203 (Befähigte Personen): suitable vocational training, professional experience and a recent, time-proximate occupation with scaffold inspection. The employer selects and, in practice, appoints the person in writing, naming the type of scaffolds covered. The employer must give the inspector the time, information and freedom from instruction needed to judge safety honestly. DGUV Information 201-011 provides the practical checklists for the appointed person.

How CIVAC supports the scaffold inspector role
CIVAC maps scaffold inspection as a role with a file of its own. The written appointment of the competent person (befähigte Person), the competence evidence under TRBS 1203 and the assembly and use instructions for the systems in service sit in the documentation area, versioned instead of scattered across site folders. Every handover inspection and every inspection after a storm or a modification becomes a scheduled task with an owner and a reminder, with the completed scaffold tag, the photos and the release decision attached.
Training is documented per person with proof, and stand-in and handover live in the same role file. Every change lands in an append-only audit trail, so at a site visit it stays traceable who released which scaffold and when. Data is held in the EU. Where the role cannot be filled in-house, an external competent person can be appointed through CIVAC, at 49 euros per role per month.
