What are the appropriate actions for managing a passenger with a severe burn?

Covering a severe burn with a sterile, non-adhesive dressing is the appropriate action because it helps protect the burn area from infection and further damage. A sterile dressing promotes a clean environment for the wound, which is crucial in the initial management of burns. Keeping the area covered can also help with pain management, as the dressing acts as a barrier to external irritants and can provide a degree of insulation.

In contrast, applying ice directly to the burn, although it may seem soothing, can actually exacerbate the injury by causing further skin damage and increasing the risk of complications. Leaving the burn exposed to the air could lead to increased pain and exposure to bacteria, heightening the risk for infections. Using a wet cloth can provide temporary relief, but it is generally not advisable for severe burns because the water may not be sterile and could introduce contaminants to the wound.

Thus, covering the burn with a sterile, non-adhesive dressing is the best practice for ensuring the burn is managed effectively while minimizing the risk of infection and promoting healing.
