Heat-Related Burn

Heat Burn

What it is

A burn occurs when the skin comes into contact with something very hot, such as fire, steam, boiling liquid, or a hot surface. Water-filled blisters may also appear.

What you can do at home

What to do
  • Cool the burn immediately by running cool (not ice-cold) water over it for at least 20 minutes. 
  • Remove clothing and jewelry near the burn, unless they are stuck to the skin. 
  • Gently wash the burn with tap water and mild, unscented soap. 
  • If the leg or arm is burned, keep that part of the body slightly elevated as often as possible for 1 to 2 days to help prevent swelling. 
  • To reduce pain, take acetaminophen (Tylenol) or ibuprofen (Advil). When in doubt, ask a pharmacist for advice.

Important: Ibuprofen is contraindicated for children under 6 months of age. 

If there is no open wound and the blister has not popped

  • Leave the burn uncovered. 
  • Apply an unscented moisturizer or aloe vera gel. 
  • Keep the burn clean. 

If there is an open wound, or if the blister has popped

  • Apply an antibiotic ointment (e.g., Polysporin), unless contraindicated. When in doubt, ask a pharmacist for advice. 
  • Cover the burn with a dressing and change it once a day or when it becomes dirty. Wash the burn before applying a new dressing. 
What to avoid
  • Do not apply butter, toothpaste, or other greasy products. 
  • Do not pop water blisters (also called blisters). 
     
When to seek medical attention
A water blister (blister) larger than 2.5 cm
Pain that continues even after taking medication
A burn that has a bad smell, or redness, swelling, or warmth around the burn, or pus (yellow-green fluid)
Fever
A burn that has not healed after 14 days, even after following the recommended care
Difficulty breathing, coughing, a hoarse voice, or black mucus when coughing

It is important to check whether the burned person’s tetanus vaccination is up to date.
