What is the first action you should take for a swimmer with a significant burn?

The first action that should be taken for a swimmer with a significant burn is to remove the swimmer from the source of the burn. This is essential to prevent further injury and stop the burning process. If the swimmer remains in contact with the heat source or environment causing the burn, they may suffer additional damage, which could escalate the severity of their injuries.

Removing the swimmer from the burn source not only mitigates the immediate danger but also allows for the proper assessment of the injury, enabling you to take subsequent steps such as cooling the burn with running water or seeking further medical assistance. This initial action lays the foundation for effective treatment and helps ensure the safety and well-being of the swimmer.
