ABSTRACT:
An alerting mechanism integrated with a hand-held whistle utilizing a structural member having a first and a second surface. The structural member is secured to the whistle or a cavity found in the whistle structure, to permit the structural member to rotate and be held between a first and a second position. The first position exposes the first surface of the structural member while the second position exposes the second surface of the structural member. Coloration or other marking may be employed on the first surface to visually distinguish the first surface from the second surface.
