How to Care for a Burn: First Aid and When to Get Help

Burns can damage skin and deeper tissue through heat, steam, hot liquids, chemicals, electricity, or sunlight. Prompt first aid can limit further injury, but it cannot replace medical care when a burn is serious. This guide covers basic first aid for a minor thermal burn; chemical and electrical burns need urgent professional guidance.

Before helping, make sure the area is safe. Do not approach flames, exposed wires, or spilled chemicals if doing so puts you at risk. Call 911 for a life-threatening injury, trouble breathing, shock, or a major burn. If you are uncertain how serious the burn is, contact a health professional or emergency service for advice.

What You’ll Need

Clean, cool running tap water or a clean, cool wet cloth if running water is unavailable.
A clean, non-fluffy dressing, sterile gauze, or plastic wrap to cover a minor burn loosely.
Clean hands or disposable gloves, if available.
A phone to contact emergency services or a health professional when needed.

Step-by-Step

Stop the burning. Move away from the heat source if it is safe. Put out burning clothing by stopping, dropping, and rolling, or smother flames with a blanket; do not run. If clothing is stuck to skin, leave it in place. For a chemical spill, avoid touching the substance and follow emergency-service instructions.
Check for an emergency. Call 911 if the person has trouble breathing, is unconscious or confused, appears to be in shock, or has a large or deep burn. Also seek urgent care for burns on the face, hands, feet, genitals, or over a major joint; burns that circle a limb or the chest; and chemical or electrical burns. Do not delay a call to cool a severe injury.
Cool a minor thermal burn. Hold the affected area under cool, clean running water for about 20 minutes, as soon as possible. If running water is not available, use a clean, cool, wet cloth and replace it as it warms. Cooling helps reduce heat in the tissue and can ease pain. Do not use ice or ice water, which can worsen tissue damage.
Remove restrictive items. While cooling, gently remove rings, watches, belts, and loose clothing near the burn before swelling begins. Do not pull off anything stuck to the skin, and do not peel away burned material.
Protect the area. After cooling, cover the burn loosely with sterile gauze or a clean, non-fluffy dressing. Plastic wrap can be laid over the area as a temporary cover; do not wrap it tightly around a limb. Keep pressure and friction off the injury. Avoid adhesive directly on burned skin.
Leave blisters intact. Do not pop, drain, or peel them. Blisters help protect the underlying skin, and breaking them can increase the risk of infection. If one breaks on its own, keep the area clean and loosely covered; seek medical advice if it is large, painful, or showing signs of infection.
Watch for changes. Keep the dressing clean and dry, and check the area regularly. Get medical care if pain, redness, swelling, or drainage worsens, if the burn looks deep or larger than expected, or if healing is not progressing. Seek advice sooner for a child, an older adult, or someone with a condition that may affect healing.

Common Mistakes

Using ice: Ice can further injure burned skin. Use cool running water, not ice or very cold water.
Applying butter, oil, toothpaste, or creams: These do not cool the tissue and can make the burn harder to assess or clean. Avoid home remedies and do not apply ointments to a serious burn.
Removing stuck clothing: Pulling material away can tear damaged skin. Cut around it only if necessary and safe, and leave the stuck portion for medical professionals.
Breaking blisters: This removes a natural protective barrier. Keep blisters intact and covered loosely.
Underestimating the cause: Chemical burns may continue damaging tissue, and electrical burns can cause internal injury even when the skin mark looks small. Get urgent medical advice rather than treating these as ordinary minor burns.
Wrapping too tightly: Swelling can make a tight bandage restrict circulation. Cover loosely and do not encircle a limb with plastic wrap.

Tips

Start cooling promptly, but prioritize calling for help when the burn is serious.
Cool only the burned area when possible. Keep the rest of the person warm, especially a child or someone with a large burn, to reduce the risk of getting chilled.
Use clean materials and wash your hands before and after caring for a minor burn. Avoid cotton balls or fluffy fabric that may leave fibers in the injury.
Do not judge severity only by pain. A deep burn can damage nerves and may hurt less than a more superficial injury.
If a burn is on the face, near the eyes, or affects breathing, treat it as urgent. Swelling and smoke exposure can create problems beyond the visible skin injury.

Troubleshooting

You cannot reach running water: Use a clean, cool, wet cloth and keep replacing it as it warms. Do not use ice. Arrange medical care if the burn is serious or you cannot cool it adequately.
The burn is chemical: Call emergency services or poison control for instructions. If directed and it is safe, remove contaminated clothing and rinse the skin with plenty of water; brush off dry chemicals first without spreading them. Do not try to neutralize the chemical with another substance.
The burn is electrical: Do not touch the person until the power source is off and the scene is safe. Call 911 and get urgent medical evaluation, even if the skin injury appears minor.
Pain or swelling gets worse: Loosen or remove a dressing if it is tight, without disturbing the burn, and seek medical care. Worsening redness, warmth, pus, fever, or increasing pain can signal a complication that needs professional assessment.
You are unsure how serious it is: Contact a clinician or emergency service. A burn’s depth can be difficult to judge at home, and prompt assessment is safer than waiting when the injury is substantial or in a sensitive area.

Frequently Asked Questions

How long should I cool a burn?

For a minor thermal burn, use cool running water for about 20 minutes. Start as soon as you can, but do not delay emergency help for a severe burn.

Should I put ice on a burn?

No. Ice and ice water can worsen skin damage. Use cool, clean running water instead.

Should I cover a burn?

After cooling, cover a minor burn loosely with clean, non-fluffy material or sterile gauze. Do not use a tight wrap or place adhesive directly on the burned skin.

When does a burn need medical care?

Seek urgent care for a deep or extensive burn, a burn on the face, hands, feet, genitals, or a major joint, or any chemical or electrical burn. Call 911 for severe symptoms, breathing problems, or signs of shock.

Can I pop a burn blister?

No. Keep blisters intact because they protect the skin underneath. Get medical advice if a blister is large, very painful, breaks and becomes concerning, or appears infected.

Can I treat a chemical burn like a heat burn?

No. Chemical burns may need specific first aid and urgent evaluation. Contact emergency services or poison control, and follow their instructions rather than applying household remedies.
