The correct approach to treating a third-degree burn involves cooling the affected area and protecting it from further injury and contamination. Covering the burn with a clean cloth helps to shield it from bacteria and debris, which is essential since the skin's protective barrier has been compromised. It is crucial to avoid applying cold water directly for an extended period, as this could lead to further tissue damage due to the severity of the burn.

Seeking medical help promptly is also necessary, as third-degree burns typically require professional evaluation and treatment, including possible interventions such as fluid replacement, pain management, or surgical procedures like skin grafting.

In this context, while applying ointment can be beneficial for less severe burns, it's not appropriate for third-degree burns, where the risk of infection is high. Instead, basic first aid measures focused on cleaning and protecting the area should be prioritized.
