What kind of occupations might NOT require a Blue Card?

The choice indicating that administrative staff might not require a Blue Card is correct because these positions typically do not involve direct physical work with construction sites or hazardous materials. The Blue Card is primarily designed for those whose occupations are directly related to construction projects, which include high-risk responsibilities such as handling hazardous materials, performing demolition work, or installing scaffolding.

Administrative staff generally work in an office environment, managing paperwork, scheduling, and communication rather than engaging in activities that pose safety risks on construction sites. Therefore, they may not need the specialized training and certification that comes with obtaining a Blue Card, which is focused on ensuring safety and compliance in physically hazardous environments.
