Treat second-degree burns using the following steps:

1. Follow the DRSABCD St John Action Plan.
2. If clothing is on fire, have the injured person stop, drop and roll.
3. Stop them from moving around.
4. Assess their breathing.
5. Immerse the burn in cool running water for 20 minutes.
6. Do not apply ice since it could cause further damage.
7. Do not remove clothing that is stuck to the skin.
8. Do not puncture blisters or apply ointments, which could cause infection.
9. Cover the burnt area with a light, non-stick dressing, or clean, dry, non-fluffy material loosely and secure it with gauze or medical tape.
10. Lay the person down, elevate their feet about 30 cm, elevate the burn above the heart and cover him/her with a blanket.
11. When in doubt, call Triple Zero (000) for immediate medical assistance. Burns may be lethal.
