Call 911 now if you have:

The person is on fire, was in an enclosed fire, or breathed smoke, with any trouble breathing, hoarse or changed voice, noisy/harsh breathing (stridor), coughing up black/sooty mucus, or singed nose hairs or facial burns (airway swelling can close the throat fast)
A large burn, roughly the size of the person's palm or bigger, or a burn covering a large area of the body (more than about 10% of body surface)
A burn that looks white, waxy, leathery, charred, or blackened, or where the skin is numb (a sign of a deep, full-thickness burn)
Any electrical burn (including lightning or high-voltage) or a burn with collapse, confusion, seizure, or an abnormal heartbeat; do not touch someone still in contact with a live wire, separate them with a non-metal object first
A large chemical burn, a chemical burn to the eye, or a chemical burn with trouble breathing, fainting, or severe pain (while calling, brush off dry chemical and rinse with lots of water)
Signs of shock: pale/clammy skin, rapid or weak pulse, fainting, or confusion
Deep or widespread burns in an infant, young child, or older or medically fragile person

When in doubt about a possible emergency, call 911. Do not drive yourself.

Call 911 for large burns (palm-sized or bigger), deep/white/charred or numb burns, and any burn with smoke inhalation, breathing trouble, electricity, or major chemicals.
Go to the ER or a burn center for deep burns or burns on the face, hands, feet, genitals, joints, or that wrap around a limb, even if they look small.
Small, superficial burns can be cooled with running water and managed at home; do not use ice or butter, do not pop blisters, and watch for signs of infection.

ER, Urgent Care, Doctor, or Home?

Go to the ER

The ER (or a dedicated burn center) is the right choice for deep burns, burns to high-risk areas like the face, hands, feet, genitals, or joints, burns that wrap around a limb, and any burn from electricity, chemicals, or a fire with possible smoke inhalation. These burns can worsen over hours, threaten the airway or circulation, and often need specialized wound care, so err toward the ER rather than waiting.

A deep (full-thickness) burn of any size, or a blistering burn on the face, eyes, ears, hands, feet, genitals, or over a major joint
A burn that circles all the way around a limb, finger, toe, or the chest
A blistering (second-degree) burn larger than about 3 inches across, or larger than the palm
A chemical or electrical burn that is not clearly small and superficial, even if it looks minor on the surface
Severe, uncontrolled pain, or a burn from a house fire, explosion, scald with hot oil/grease, or steam
Suspected non-accidental injury or abuse, in a child or adult

Urgent care

A blistering (second-degree) burn smaller than about 3 inches across on an arm, leg, or torso, away from the face, hands, feet, genitals, and joints
A superficial burn that is very painful, dirty, or you cannot keep clean and dressed at home
A minor burn that is not healing, or where you need a wound checked, dressed, or a large blister evaluated
You are due for or unsure about a tetanus shot after a burn
Early signs of a mild skin infection (spreading redness, warmth, pus) in an otherwise small burn

See your doctor / telehealth

A minor burn that is slow to heal, still painful after several days, or looks like it may scar
A healing burn with increasing redness, swelling, warmth, pus, red streaking, or fever, which can signal infection
Questions about long-term skin care, itching, discoloration, or scar management after a burn heals
A minor sunburn or small scald when you want reassurance or advice, often handled by telehealth
Checking your tetanus vaccination status is up to date

Safe to manage at home

Reasonable at home for first-degree burns (red, dry, painful, no blisters, like most sunburns) and small second-degree burns under about 2 inches, away from the face, hands, feet, genitals, and joints
Cool the burn right away: run cool (not ice-cold) water over it for 10 to 15 minutes or until pain eases, or use a cool, clean, damp cloth; do not use ice, butter, toothpaste, or grease
Do not break blisters; intact blisters protect against infection. If one breaks on its own, gently clean with water and apply an over-the-counter antibiotic ointment
Cover loosely with a clean, non-stick dressing, and take acetaminophen or ibuprofen for pain; aloe vera or moisturizer can soothe after cooling
Remove rings, watches, and tight clothing near the burn before it swells, unless fabric is stuck to the skin

Common Causes

These are possibilities to discuss with a clinician, not a diagnosis. Only an exam and sometimes tests can tell which applies to you.

Thermal burns from flames, hot surfaces, steam, or scalds from hot liquids or grease (this is education, not a diagnosis of your specific injury)
Sunburn and other ultraviolet or radiation exposure
Chemical burns from acids, alkalis, or strong household or industrial cleaners
Electrical burns from outlets, cords, appliances, or high-voltage lines and lightning
Friction or contact burns (for example, from road rash or hot machinery)
Inhalation injury of the airway from breathing hot air, smoke, or chemical fumes

What to Expect if You Are Seen

A clinician estimates the burn's depth and size (percent of body surface) and checks the location and whether it wraps around a limb
The burn is cleaned; loose dead skin or some blisters may be trimmed, and a specialized dressing or topical antibiotic (such as ointment) is applied
You may get a tetanus shot, pain medicine, and for larger burns, IV fluids
For possible smoke inhalation, expect oxygen, monitoring of your breathing, and sometimes a scope of the airway or blood tests; electrical burns may include an ECG and urine tests
Serious burns may be referred or transferred to a specialized burn center, with instructions for follow-up dressing changes

Worried about the cost?

Before You Go, Have This Ready

How and when the burn happened (flame, scald, chemical name, voltage), and whether smoke or fumes were involved
Your tetanus vaccination date, allergies, and a current medication list
For chemical burns, the product container or a photo of the label/ingredients if it is safe to bring
The person's age and any major medical conditions (diabetes, heart, lung, or immune problems)

Frequently Asked Questions

How do I know if a burn is second- or third-degree?

Second-degree (partial-thickness) burns are red, wet, blistered, swollen, and very painful. Third-degree (full-thickness) burns damage all skin layers and often look white, leathery, charred, or blackened, and may feel numb because nerves are destroyed. Any suspected third-degree burn, or a deep burn, needs emergency care.

Should I pop a burn blister?

No. Intact blisters act as a natural barrier against infection. Leave them alone. If a blister breaks on its own, gently clean it with water and apply an over-the-counter antibiotic ointment, then cover loosely. Large blisters may need a clinician to drain or trim them safely.

Is it safe to put ice, butter, or toothpaste on a burn?

No. Ice can cause further skin damage, and butter, toothpaste, oils, and home remedies trap heat and raise infection risk. Cool the burn with running cool water or a cool, damp cloth for 10 to 15 minutes, then cover loosely with a clean, non-stick dressing.

Why is a burn on my hand or face treated as more serious?

Burns to the face, eyes, ears, hands, feet, genitals, and joints, or burns that circle a limb, can cause lasting problems with function, appearance, movement, or the airway, even when small. These are considered high-risk and should be evaluated in the ER or a burn center.

My burn looked minor but seems worse today. Is that normal?

Burns can deepen and swell over the first 24 to 48 hours, so a burn can look worse before it looks better. Watch for spreading redness, increasing pain, swelling, pus, red streaks, or fever, which suggest infection and warrant prompt medical evaluation.
