Do Lifeguards at Nudist Colonies where bathing suits?

Do Lifeguards at Nudist Colonies where bathing suits? The easy answer seems to be no they do not. They are at a nudist colony therefore why do they have to. But this issue is more complicated than that. First of all if they were to be nude how are they to be distinguished from the patrons. If everyone is nude how does one know which person is a guard. There is no possible way to tell them apart. You may say painting but that comes with to many risks, such as allergies etc. Apart from all of this though, I don't think that everyone at the colony would be comfortable with nude lifeguards. If I am a nudist, while I may be comfortable with nudes around me, I may not be comfortable with nudes touching me. If I am being saved I may not want a male lifeguards stuff all up in mine, and this goes for both male and female. The idea of a nude lifeguard is not feasable and would not work. Ever.
