Flagging (tape)

It is commonly made of PVC or vinyl, though wood fibre cellulose-based biodegradable flagging also exists.

Flagging is widely used in wildlfire suppression both as a navigational aid for firefighters and to mark trees.

Hot pink flagging is considered the best colour for marking escape routes due to its visibility.

Flagging tape can be used in the field of crime scene photography to show the trajectory of bullets.
