What safety practices should be observed when working on aircraft electrical systems?

• A. Working on live circuits for efficiency
• B. De-energizing circuits before work
• C. Wearing basic uniforms only
• D. Ignoring protective gear in secure areas

Answer: (B)

When working on aircraft electrical systems, the essential safety practice is de-energizing circuits before performing any work. This is crucial because live circuits pose a significant risk of electric shock, which can be lethal. By de-energizing the circuits, technicians ensure their safety and prevent unintended short circuits and electrical fires that could arise from working on energized components. Additionally, this practice allows for a more controlled environment where necessary repairs and diagnostics can be performed without the interference or hazards associated with live electricity. It is a foundational safety protocol in aircraft maintenance and is in line with industry standards and regulations aimed at protecting personnel and ensuring the integrity of the aircraft systems.
