What tags are used to indicate tanks that have not had the special chemical introduced during FNA procedures?

The use of green tags in the context of indicating tanks that have not had the special chemical introduced during FNA (Fuel Neutralization Application) procedures serves a vital purpose in ensuring safety and protocol compliance. The color green is typically associated with a "go" status or an indication that something is clear for use or operation, specifically in this context signaling that the tanks are still considered safe.

In operations involving hazardous materials, clear labeling is essential for proper handling and understanding of current tank conditions. Green tags inform personnel that the aforementioned chemical application has not yet occurred, thus indicating the need for caution and adherence to safety measures before engaging with these tanks. This color coding aids in effective communication among the crew and minimizes the risks associated with mishandling hazardous materials.

Using contrasting colors for other tagging procedures, such as red for danger or warning, creates a robust system for quickly assessing tank statuses. Such a tagging system helps ensure that all personnel are aware of specific handling protocols and the current state of each tank.
