How do you wear a whistle and chain on a police or security uniform?
The whistle chain attaches to the button for the right epaulet (shoulder strap) of your uniform shirt. The chains come in 2 varieties: a button-hook style and a clip on style. The button hook style is more common. Unhook the shoulder strap, attach the button hook under the button, then re-button the shoulder strap over the end of the whistle chain. The chain will then go from your shoulder strap to your right shirt pocket. If you are carrying the whistle on the outside, you need a whistle hook. They usually come with a clasp style back. Attach the whistle hook to the center of the flap for the right shirt pocket. Then attach the whistle chain to the whistle and hang the whistle on the hook.
