A minor burn or scald: a case-based approach
This is an illustrative educational case, not a real patient. It follows an adult who spills a hot drink on their hand, to explain how NHS teams think about minor burns and scalds and, above all, the correct first aid. Acting quickly and correctly in the first minutes can reduce how deep a burn becomes and how much it hurts. The single most important step is to cool the burn under running water for 20 minutes. The aim is to explain safe first aid, common mistakes to avoid, and when a burn needs medical help. This is not a guide to treating serious burns yourself, and it names no medicine doses. For large, deep, or facial burns, or if someone struggles to breathe after smoke or fire, phone 999.

The case: a spilt hot drink
An adult knocks over a mug of tea, splashing the back of one hand. The skin quickly turns red and stings, and a small blister begins to form. This is a scald, a burn caused by hot liquid or steam, and it is one of the most common household injuries, especially in young children. Most such burns are minor and heal well if treated promptly and correctly. The immediate priority is not creams or dressings but cooling the injury and removing anything that could trap heat. How well those first few minutes are handled often makes the difference between a burn that heals quickly and one that becomes deeper and more painful. Knowing the right steps in advance means you can act without hesitating.
Correct first aid: cool running water for 20 minutes
The recommended first aid for a burn or scald is to cool it under cool or lukewarm running water for 20 minutes, as soon as possible after the injury. This helps stop the burning process, ease pain, and limit damage, and it is worth doing even up to about three hours after the injury if you could not do it straight away. Do not use ice, iced water, or any creams or greasy substances such as butter, as these can worsen the injury. While cooling, gently remove any clothing or jewellery near the burn, unless it is stuck to the skin, in which case leave it. After cooling, keep the person warm overall, for example with a blanket, taking care not to chill them, especially children, since prolonged cooling can lower body temperature.
After cooling: covering and comfort
Once the burn has been cooled for the full 20 minutes, cover it loosely with cling film, laid in a layer over the burn rather than wrapped tightly around a limb, or use a clean, non-fluffy cloth or plastic bag for a hand or foot. This keeps the area clean and reduces pain by keeping air off the exposed nerves. Do not burst any blisters, as the skin underneath protects against infection while it heals. Simple over-the-counter pain relief, taken as directed, can help with discomfort; a pharmacist can advise on suitable options and on caring for a minor burn as it heals. Keep the area clean and watch for signs of infection, such as increasing pain, redness, swelling, or pus, over the following days.
What not to do
Some traditional remedies do more harm than good. Do not apply ice or very cold water directly, as this can damage tissue and deepen the burn. Do not put butter, oil, toothpaste, or ointments on a fresh burn, as they trap heat and can increase the risk of infection. Do not burst blisters or peel away loose skin yourself. Avoid using fluffy cotton wool or sticky dressings directly on the wound, as fibres can stick. Do not remove anything that is firmly stuck to the burn. If in doubt, keep it simple: cool with running water, cover loosely with cling film, relieve pain, and seek advice. Getting these basics right protects the skin and gives the best chance of quick, clean healing.
When to seek medical help
Many minor burns can be looked after at home with a pharmacist's advice, but some need medical care. Seek help for burns larger than the affected person's hand; burns that are deep, look white, brown, or charred, or that cause little pain because nerves are damaged; and any burn to the face, hands, feet, genitals, or over a joint. Chemical and electrical burns, and burns in babies, young children, older people, or those who are pregnant or unwell, should always be assessed. Go to A&E or call 999 for large or deep burns, and if someone has breathed in smoke or fumes or shows signs of shock. For smaller burns you are unsure about, contact NHS 111 or a pharmacist, who can advise whether further care is needed.
In short
Key takeaways
- Cool a burn or scald under cool or lukewarm running water for 20 minutes as soon as possible — this is the key first-aid step.
- Do not use ice, iced water, butter, creams, or greasy substances, and do not burst blisters.
- After cooling, cover loosely with cling film or a clean non-fluffy cloth, and use simple pain relief if needed.
- Seek help for burns bigger than the person's hand, deep burns, or burns to the face, hands, feet, or genitals; call 999 for large or deep burns.

Answers
Frequently asked questions
How should I treat a minor burn straight away?
Cool it under cool or lukewarm running water for 20 minutes as soon as you can, remove nearby clothing or jewellery unless stuck, then cover loosely with cling film. Do not use ice, creams, or butter, and do not burst blisters.
When is a burn an emergency?
Call 999 for large or deep burns, burns to the face, hands, feet, or genitals, chemical or electrical burns, or if someone has breathed in smoke or fumes or seems in shock. For smaller burns you are unsure about, contact NHS 111 or a pharmacist.
Why should I not put ice or butter on a burn?
Ice can damage the skin and deepen the injury, while butter, oil, and creams trap heat and raise the risk of infection. Cool running water is safer and more effective, which is why it is the recommended first aid.
