Final answer:
Retractable lanyards are a type of lanyard that can extend and retract for convenience and safety.
Step-by-step explanation:
A retractable lanyard is a type of lanyard that can extend and retract, allowing users to easily adjust the length of the lanyard as needed. It usually consists of a flexible cord or strap, a retracting mechanism, and a clip or hook to attach items. Retractable lanyards are commonly used in workplaces, especially in industries like construction, manufacturing, and utilities.
One true characteristic of retractable lanyards is that they provide convenience and flexibility for users. They allow the wearer to extend the lanyard when needed to access an item or perform a task and retract it when not in use, reducing tangling or tripping hazards. Another true characteristic is that retractable lanyards often have a built-in braking system or a locking mechanism to control and prevent rapid retraction, ensuring safety.
