ATXplained: Why Do Austin Lifeguards Have So Many Different Types Of Whistles? 

R.I.P. the whistle

For sure a difference in whistle types. I work at great wolf lodge and our whistles go something like this 1 short whistle : To get the attention of a guest. 2 short whistles : To get the attention of a lifeguard. 3 short whistles : To call for a supervisor 1 long : activate EAP 2 long : life threatening emergency 3 long : same as above but in our lazy river

Your whistles are different from my lifeguard job

Loud whistles
