The first step in caring for someone with a burn is ensuring your own safety and then removing the person from the source of the burn. Before you touch the victim, cool the wound, or do anything else, you need to stop the burning process by separating the person from whatever is causing the injury. After that, cooling the burn with running water is the most important treatment you can provide.
Stop the Burning Process
This sounds obvious, but in the urgency of the moment it’s easy to skip straight to treating the wound. The very first action is to move the person away from the heat source, or move the heat source away from the person, whichever is safer. For a kitchen burn, that might mean pulling a hand away from a hot pan. For a house fire, it means getting the person out of the burning structure. For clothing that has caught fire, it means smothering the flames with a blanket or having the person stop, drop, and roll.
Every second the skin stays in contact with the heat source, the burn gets deeper and larger. Stopping that contact is what prevents a minor burn from becoming a serious one.
Check for Scene Safety First
Before you reach anyone, make sure the scene won’t injure you too. This step is especially critical for electrical and chemical burns, where the danger isn’t always visible.
For electrical burns, stay at least 50 feet away from downed or sparking power lines. If possible, turn off the power source. If you can’t, use a dry, non-conducting object made of cardboard, plastic, or wood to separate the person from the electrical source. Never touch someone who may still be in contact with a live current.
For chemical burns, put on gloves before touching the person. Brush off any dry chemical residue first, then remove contaminated clothing and rinse the affected skin for at least 20 minutes under running water, ideally in a shower. Protect the person’s eyes from splashing chemicals during this process.
Cool the Burn With Running Water
Once the person is safe and the burning has stopped, cooling is the single most effective first aid treatment. Run cool (not cold) water over the burned area. The Mayo Clinic recommends about 10 minutes, and the International Liaison Committee on Resuscitation strongly recommends immediate active cooling with running water for both adults and children, though research hasn’t pinpointed a single optimal duration.
Cooling does three things: it reduces pain, limits how deep the burn penetrates into the tissue, and helps reduce swelling. The key word is “cool.” Ice-cold water or ice itself can actually worsen tissue damage and drop body temperature, especially in young children. If you’re cooling a burn on a small child, watch for shivering or signs that their whole body is getting too cold.
What Not to Put on a Burn
A number of home remedies that people reach for instinctively will make things worse. Butter melts on a hot burn, increasing pain and introducing bacteria. Ice numbs pain temporarily but damages already-injured tissue. Toothpaste raises the risk of infection because the tube isn’t sterile. Alcohol causes intense burning pain with no healing benefit. Cold meat from the fridge may feel soothing for a moment, but it’s a direct route to infection. Stick with cool running water.
Cover the Burn After Cooling
Once you’ve cooled the burn, cover it loosely with a clean, non-stick material. Plastic kitchen wrap works well in a pinch because it’s clean, won’t stick to the wound, and keeps air off the exposed skin (which reduces pain). If you have a first aid kit, use a sterile non-adherent dressing, then layer dry sterile gauze over it. Never place dry gauze or cotton directly against a raw burn surface; it will stick to the wound and cause more damage when removed.
The goal at this stage is simply to protect the burned skin from contamination and further irritation while the person gets to medical care if needed.
Burns That Need Emergency Care
Not every burn requires a trip to the hospital, but certain types always do. The American Burn Association flags these situations for referral to a specialized burn unit:
- Location: Burns on the face, hands, feet, genitals, or over major joints carry higher risks of complications and scarring.
- Size: Burns covering more than 20% of the body in adults (or more than 10% in children under 10 or adults over 50) need specialized care.
- Depth: Any full-thickness (third-degree) burn larger than about the size of the person’s palm.
- Cause: All electrical burns (including lightning strikes), chemical burns, and burns involving smoke or fume inhalation.
- Other injuries: Burns combined with fractures, blast injuries, or pre-existing medical conditions that could slow healing.
For smaller burns that blister but don’t meet these criteria, cooling, covering, and taking an over-the-counter pain reliever like ibuprofen or acetaminophen is typically enough to manage things at home. If the burn doesn’t improve within a few days, or if you notice increasing redness, swelling, or pus, that’s a sign of infection and a reason to get it checked.
Quick Sequence to Remember
In the moment, burn first aid comes down to a simple order: safety first, stop the burning, cool with water, cover loosely. The instinct to immediately treat the wound is strong, but the person who checks for hazards and removes the victim from the heat source before doing anything else will prevent the most harm. Everything after that, the cooling, the covering, the pain management, builds on that critical first step.
