Checklist Items (21)
Assess the burn
Determine if the burn is minor (superficial or small partial-thickness) before proceeding with first aid.
Determine burn depth
Look for redness, pain, and possible blistering; superficial burns affect only the outer layer.
Check burn size
Measure the burned area; minor burns are usually less than 3 inches (about 7.5 cm) in diameter.
Identify exclusion criteria
If the burn involves the face, hands, feet, genitals, or covers a large area, seek professional care.
Run cool water over the burn
Use cool (not cold) water for 10-20 minutes; do not use ice.
Use a clean cool compress if water unavailable
Soak a clean cloth in cool water, wring out excess, and gently place on the burn.
Avoid ice or very cold water
Extreme cold can worsen tissue damage and increase pain.
Wash with mild soap and water
Use a gentle, fragrance-free soap and lukewarm water to cleanse the burn.
Pat dry with sterile gauze
Use a clean gauze pad or soft cloth to dry the area; do not rub.
Do not scrub or break blisters
Leave intact blisters alone; breaking them can introduce infection.
Apply petroleum jelly or aloe vera gel
Spread a thin layer to keep the burn moist and reduce pain.
Cover with non-stick sterile dressing
Use a gauze pad or specialized burn dressing that won’t stick to the wound.
Secure with medical tape
Wrap tape loosely around the dressing to hold it in place without restricting circulation.
Look for increased redness or swelling
Expanding redness beyond the burn edges can indicate infection.
Check for pus or foul odor
Yellow or green drainage with a bad smell suggests bacterial growth.
Note fever or increasing pain
A temperature over 100.4°F (38°C) or worsening pain warrants medical evaluation.
Take acetaminophen or ibuprofen as directed
Follow dosing instructions on the package; do not exceed the maximum daily dose.
Keep the burned area elevated
If possible, raise the limb above heart level to reduce swelling and throbbing.
Apply a clean cool cloth for comfort
A damp, cool (not cold) cloth can provide soothing relief between medication doses.
Seek medical attention if needed
Know when a minor burn requires professional evaluation to prevent complications.
Burn larger than 3 inches or on sensitive areas
Face, hands, feet, genitals, or major joints need urgent care regardless of depth.
Signs of infection appear
Increasing redness, pus, fever, or worsening pain after 24-48 hours.
Burn caused by chemicals, electricity, or inhalation
These sources can cause deeper damage than visible; seek emergency care.
