System and method for a retractable reel safety flags on a strap

A method for deploying a retractable safety banner;

• winding out the safety banner from a reel inside of a reel housing, wherein the safety banner comprises a strap having a plurality of strap sections, wherein the strap sections are longer than a flag attached to a bottom surface of each strap section, wherein the flags are configured to extend downward past a lower edge of the strap sections and hang perpendicularly from the strap sections when the strap sections are unwound off the reel, wherein the safety banner is stored on the reel inside of the reel housing;
• winding in the safety banner through an organizing guide formed in the reel housing;
• and
• aligning the flags and strap in the organizing guide so that the flags are aligned along the longitudinal axis of the strap so that the safety banner is stored on the reel with the flag section of strap to which it is attached;
• and
• sensing a tension event from a tension sensor that measures tension on a deployed safety banner, wherein a processor determines a tension event when a tension on the deployed safety banner is changed.
