The indication of improper use of flexible cords and cables in the context of electrical safety is primarily tied to the potential hazards posed by their placement. Running flexible cords through doorways, windows, or similar openings can create a significant risk. This setup can lead to abrasion of the cords, increasing the chances of electrical shorts or shocks due to wear and tear over time. Additionally, such placements can cause tripping hazards and hinder the movement of objects or individuals in those areas.

In contrast, the other options highlight scenarios where flexible cords and cables are being utilized appropriately. Using extension cords for portable lamps or temporary installations can fall within acceptable safety practices if they are designed for such purposes. Permanent installations, however, typically require fixed wiring as per electrical codes, and while flexible cords should not be used for permanent installations, this indicates that their incorrect use is being contextualized appropriately in terms of safety. Thus, recognizing the dangers of running cords through openings is essential for maintaining safe electrical practices.
