when the burn turns red.
when the burn covers a large area or shows signs of infection.
when the burn is on your hand but stops hurting after a day.

Explanation:

• Question 4: First - degree burns affect only the outer layer of skin. Redness and mild swelling are common as the skin's surface is irritated. Charred or blackened skin is more typical of third - degree burns. Numbness is not a primary symptom of first - degree burns (more likely in deeper burns). Blisters and severe pain are common in second - degree burns.
• Question 5: Using ice directly on a burn can cause further damage as it can lead to frostbite - like effects on already injured tissue. Cooling under running water, covering with a non - stick bandage, and applying antibiotic ointment (in some cases, after cleaning) are generally accepted first - aid steps for minor burns.
• Question 6: When a burn covers a large area or shows signs of infection (such as increased redness, swelling, pus, or fever), medical attention is needed. A burn smaller than a dime is usually minor. A burn turning red is a normal part of the healing process for many burns. A burn on the hand that stops hurting after a day is likely a minor burn and may not require immediate medical attention unless there are other concerning symptoms.

Answer:

1. Redness and mild swelling.
2. Use ice directly on the burn.
3. When the burn covers a large area or shows signs of infection.
