Which selection is not a safety procedure used during overhaul at an aircraft incident?

During overhaul at an aircraft incident, it is critical to ensure the safety of all personnel involved in the operation. One key procedure is the disconnection of aircraft batteries and taping of terminals to prevent any electrical hazards. This step is particularly important because live electrical components can pose significant risks during firefighting operations.

However, it is also essential to employ other safety measures such as wearing full protective clothing to shield firefighters from heat and potential hazards, using the palm of the hand to detect "hot spots" as a method of thermal sensing, and cooling down identified "hot spots" to prevent reignition of any fuels or flammable materials. Each of these procedures plays a vital role in ensuring that the overhaul operation is conducted safely and effectively, maintaining operational integrity and protecting the safety of the firefighting personnel.
