nadador-salvador

The person responsible for bathers on their stretch of beach, who also raises the flags: green — swimming allowed; yellow — you may go into the water but not swim; red — do not go into the water; black-and-white chequered — the lifeguard has stepped away for a while and nobody is watching the bathers. Lifeguards are on duty only during the bathing season and only on beaches designated as bathing areas.
