🔍 Key Concepts

• Electrical fire safety hierarchy – make the situation safe before attempting any repair or cutting • Difference between securing power and just removing load • Risk of short circuits and arcing when insulation is damaged

💭 Think About

• Ask yourself: Is the cable, with burned inner insulation, still safe to touch or cut while energized? • What step must always come BEFORE cutting or insulating a damaged live cable? • Does ‘removing the electrical load’ guarantee there is no voltage present in the cable?

✅ Before You Answer

• Verify which option makes the circuit definitely de-energized at the source, not just unloaded • Consider which actions could cause arcing or shock if the cable is still energized • Identify the step that aligns with standard shipboard electrical isolation procedures before any physical work on the cable
