Case Study
Work design for a warehouse clerk with spasticity and epilepsy at a plastics company


With its 121 employees, the company manufactures precision injection molded parts and closures made of plastic, from customer inquiries to project development, tool manufacture to series production, for the automotive industry, packaging industry, control technology, etc. Three of the 121 employees have severe disabilities. The employer applied to the integration or inclusion office for approval of the termination of an employee with a severe disability.

Disability and functional restriction of the employee:

The woman has mono-spasticity, which affects the left arm, and epilepsy. Due to her handicapped limited abilities, she should not be used for manual load transport, which requires lifting, carrying and handling of loads with both hands / arms. Due to epilepsy, factors that could trigger an attack (e.g. flickering lights) should be avoided. The woman is severely disabled and has a degree of disability (GdB) of 60.

Training and job:

The woman completed an apprenticeship as an office clerk at the employer. After completing her training, she received an employment contract from the employer or a full-time job as a warehouse clerk.

Workplace and task:

Different colored granules are used to manufacture the plastic parts. The employee in the warehouse manages more than 1000 types of granulate in various colors and stores them in shelves in various types of packaging (plastic bags, cardboard boxes or plastic containers). The employee receives the daily requirement (quantity and color) of granules for production via the PC. Afterwards, it provides the required granulate on a shelf for pick-up by the production staff. The granules provided are booked out of the inventory using a PC using warehouse management software. On another shelf, the employees in the production place the unused granulate afterwards. The employee posts these quantities back into the inventory after weighing. Checking in and out is via the barcode on the packaging with a special wireless warehouse hand scanner with additional input options (e.g. for the weight), which sends the information by radio to the PC with the warehouse management software. An insufficiently suitable pallet truck was available for transport for storing / retrieving and weighing the granulate. For this reason it happened that the employee had to carry and lift granules weighing 15 kg and more up to twelve times an hour in certain situations - which should be avoided due to disabilities. During the visit to the workplace, the working conditions and burdens were analyzed by the technical advisory service of the integration or inclusion office and it was found that the lifting and carrying processes must be managed by the employee using suitable tools. Initially tested and later used, a so-called mini-lifter with a platform made of stainless steel and three loading rollers. With the help of the minilifter, the narrow aisles between the shelves can also be used. For storage and retrieval, the platform of the minilifter is moved to the loading height by an electric motor and the load is pulled over the roller onto the platform or pushed onto the shelf surfaces.

Working environment:

When the power consumption is high, it occurs in areas of the company, e.g. B. also in the warehouse, for flickering lighting. Since this situation is not just unbearable for the employee suffering from epilepsy, the lighting was converted to LED technology with low power consumption. Even with higher power consumption in the consumption peaks, the lighting no longer flickers.

Assistive devices used:

Work lights walk-behind pallet trucks (small forklift / mini lifter)

Funding and participation:

The workplace could be preserved thanks to the work-friendly design of the work and the dismissal avoided. The Integration and Inclusion Office promoted the necessary tools. The advice was provided by the technical advice service of the integration or inclusion office.
