How frequently should extension cords be inspected for safety?

The correct answer states that extension cords should be inspected regularly, at least before each use. This approach aligns with best safety practices for electrical equipment. Regular inspections help to identify any visible signs of wear and tear, such as fraying insulation, loose connections, or other damage that could pose a risk of electrical hazards. Checking extension cords before each use ensures that any potential issues are caught early, which is critical in preventing accidents such as electrical shocks or fires.

Additionally, the emphasis on regular inspections reinforces the importance of proactive safety measures. By making it a habit to inspect cords before use, users increase their awareness of safety standards and promote a culture of safety in the workplace or at home. This is particularly vital in environments where cords are frequently moved or subjected to environmental stressors, making wear and damage more likely.

While other options suggest various frequencies for inspection, they do not guarantee the same level of precaution as inspecting before every use. Thus, regular checks before using extension cords are essential for ensuring ongoing safety and functionality.
