Quick Answer
A burn that covers more than 15% of a person's body surface area or a burn that affects a sensitive area such as the face, hands, or feet is considered a medical emergency.
Burn Classification and Emergency Response
Burns are classified based on their severity, which is determined by the depth and extent of the damage. The most common classification system is the “Rule of Nines,” which assigns a percentage of the body surface area to each region. For example, the head and neck account for 9% of the body’s surface area, while the arms and legs account for 18% each. A burn that covers more than 15% of the body surface area is considered a medical emergency.
Assessing the Severity of Burns
To determine the severity of a burn, look for specific signs, such as the depth of the burn and the presence of blisters. First-degree burns, which affect only the outermost layer of skin, are less severe and often heal quickly. Second-degree burns, which affect both the outermost layer and the layer beneath, are more severe and may require medical attention. Third-degree burns, which affect all layers of skin and may damage underlying tissues, are the most severe and require immediate medical attention.
Emergency Response and Treatment
If a burn is considered a medical emergency, call for emergency medical services immediately. Until help arrives, keep the burn clean and cool by running cool tap water over it for 10-15 minutes. Do not apply ice or ice water, as this can cause further damage. Cover the burn with a non-stick dressing or a sterile gauze pad to protect it from infection. Do not break blisters or remove clothing that is stuck to the burn, as this can cause further damage and increase the risk of infection.
