When is a burn an emergency?
Last updated September 3, 2026.
Emergency burns: bigger than your palm; on the face, eyes, hands, feet, joints, or genitals; white, leathery, or painless (full-thickness); chemical or electrical; circling a limb or the chest; or any burn with breathing trouble or smoke signs. Depth tells: red and painful is first-degree, blistered and very painful is second, white or charred and strangely numb is third, and third is always an emergency. Location and cause override size: small burns to the face, hands, feet, joints, or genitals still get professional care, and chemical burns (rinse 20-plus minutes), electrical burns (hidden internal damage), and smoke-inhalation signs (singed nose hairs, sooty mouth, hoarseness, breathing trouble) all mean the ER. Babies, the elderly, and people with diabetes or poor circulation get lower thresholds. For the genuinely minor burn: cool running water 10 to 20 minutes, never ice, butter, or toothpaste, a loose clean cover, un-popped blisters, and acetaminophen or ibuprofen. Days later, spreading redness, worsening pain, pus, or fever means infection and a visit.
What to do
- Bigger than your palm or full-thickness: ER.
- Face, hands, feet, joints, genitals: get care even when small.
- Chemical, electrical, or smoke signs: ER regardless of size.
- Minor burns: cool water 10-20 minutes, never ice or butter.
- Never pop blisters; spreading redness or pus later means get seen.
