Which of the following methods can be used to mark tools for accountability?

Marking tools for accountability is an essential practice in preventing Foreign Object Debris (FOD) incidents. Utilizing tags or sensors is highly effective because this method allows for precise tracking and monitoring of tools. Tags can provide information such as the tool's unique identification number, its use history, and maintenance records, which enhances accountability. Additionally, technology like RFID sensors can automate the tracking process, alerting personnel if tools are missing or left behind.

Other methods, while they may serve some purpose, do not provide the same level of durability or functionality as tags or sensors. For instance, stickers can peel off or fade over time, which could lead to loss of identification. Plastic wrap is not practical for marking accountability since it does not provide identification and can be easily removed. Paper labels can also deteriorate or become illegible due to environmental factors, making them less reliable for long-term tracking. Thus, using tags or sensors is the most reliable and effective method for ensuring accountability in tool management.
