OFF duty lifeguards sprang into action after a girl collapsed at Seaburn beach.
The teenager fainted while three RNLI lifeguards were treating a cut on her friend’s foot.
The charity’s trio were coming out of the sea following a swim at 8.15pm on Saturday when they noticed a group of people huddled around a distressed girl, near the Promenade steps.
The lifeguards found that the teenager had cut herself on a bottle.
RNLI lifeguard Cosmin Petcu calmed the girl down, while fellow lifeguards, Beth Newport and Annabelle Joyce, carried out first aid.
As they were treating the casualty, her friend complained of feeling sick and then collapsed.
Cosmin treated the unconscious teenager and kept her airway open, to stop her from choking, while Beth and Alison stopped people crowding the girl.
They managed to stabilise her, while senior RNLI lifeguard, Alexander Richardson, called an ambulance.
Paramedics took both girls away for further treatment.
Alexander Richardson said: “RNLI lifeguards are comprehensively trained in first aid and casualty care. These vital skills are never off-duty and we were pleased that were able to help both girls and wish them both a quick recovery.”
