A frequent hazard on a construction site involves a cord assembly with improperly connected what?

The correct answer is related to the safety concerns associated with electrical connections, particularly in a construction setting. Improperly connected terminals in a cord assembly can lead to several hazards including electrical shocks, short circuits, or even fires.

When terminals are not securely connected, they can create high resistance points, which can overheat and potentially lead to arcing. This poses significant dangers not only to the individual using the equipment but also to others in the vicinity. Ensuring that terminals are correctly and securely connected is essential for maintaining safety standards and operational efficiency on construction sites.

In contrast, while area lighting, breakers, and ventilation are critical aspects of a construction environment, they do not directly relate to the specific dangers posed by improperly connected terminals in electrical cord assemblies. Properly managing and connecting these terminals is foundational to preventing electrical incidents on the job site.
