Inspection Service

What is equipment and who is allowed to inspect it?

According to Betriebssicherheitsverordnung (BetrSichV) §2 are work equipment (operating equipment) tools, devices, machines or systems used for work, as well as systems requiring monitoring. The inspection of such work equipment may only be carried out by a competent person. A competent person is a person who has the necessary knowledge for the inspection of work equipment due to his professional training, his professional experience and his recent professional activity.

How often must equipment be inspected?

To this end, the Ordinance on Industrial Safety and Health stipulates in the §3 BetrSichV Gefährdungsbeurteilung: The employer shall determine and specify the type and scope of required inspections of work equipment as well as the intervals for periodic inspections in accordance with §§ 14 and 16, insofar as this Ordinance does not already contain corresponding specifications. The intervals for periodic inspections must be set so that the work equipment can be used safely until the next specified inspection. For most work equipment, this means that it must be inspected at least once a year by a competent person. Depending on the place and purpose of use as well as the intensity, equipment wears out more quickly. In order to keep the service life as long as possible and to avoid expensive new purchases, it should therefore be in the interest of every company to regularly inspect its equipment. This saves money.

Why is it worthwhile to outsource the inspection service for equipment?

Prüfservice von Carl Stahl

Carl Stahl has decades of knowledge in the field of testing and repair. More than 120 highly trained mobile test technicians are on the road every day throughout Germany and carry out the testing and repair of equipment on site at the customer's premises.
The mobile test technicians are trained on innovations in technology and regulations in regular update events. Thus, they are up to date in all areas and can optimally accompany you in the implementation in practice. According to BetrSichV §2, the assessment of work equipment requires, above all, timely professional activity. This means that there must be experience in the assessment. The training period for Carl Stahl test technicians is several months and is a major key to success in order to guarantee the safety of the professional assessment. It is often very difficult for our own employees, who only carry out this activity once a year, to obtain this professional assessment.

Some manufacturers not only require the competent person to inspect work equipment according to BetrSichV §2, but explicit training for their equipment. So sometimes you can even find sentences like this in the operating instructions: "Irrespective of the regulations of the individual countries, the hoists must be checked for functional safety at least once a year by authorised HADEF technicians or by a person who has received qualified training from them".

Thus, there are several arguments in favour of awarding the audit to competent, external partners:

The diverse knowledge about

  • the latest state of the art
  • Current regulations, rules, information from DGUV, TRBS and other relevant standards
  • Different manufacturer specifications for different series

As well as the wealth of experience

  • proper use of the work equipment
  • the assessment for safe use until the next examination.

To maintain these resources and the necessary know-how is often out of proportion to the scope of the inspection and therefore speaks in favour of external specialists. Test technicians from external companies are often already able to assess during the testing process whether a repair is still worthwhile.

At the Carl Stahl testing service, important spare parts can be found in the testing service vehicles as well as all kinds of equipment for testing. The heart of the testing process and the subsequent documentation is the Carl Stahl equipment portal.

Confusion-free labelling: Equipment due for inspection must first be marked clearly and without confusion. In practice, this is usually done using type plates with serial numbers, barcodes or modern RFID transponder technology such as the Chipster from Carl Stahl. Products that you purchase from Carl Stahl can already be marked by us ex works and are thus directly inventoried in your future digital inspection directory. This saves you time when assessing the products and documenting the commissioning.
