You do not need to blow the whistle to call a T in this situation if you ask me. Depending one what happens, you might have to separate players without any whistle at all. First of all if their is some kind of altercation, I do not know if I want a whistle in my mouth so I can have it and my teeth knocked out at the same time. You should only use the whistle if you are far away and the players cannot hear your voice. You might have a fight break out and you will have no whistle but multiple technical fouls.

Peace
