Boiling water is incredibly dangerous and will make the burn much worse. It can cause further damage to the skin, increase the risk of infection, and potentially lead to permanent scarring.
Here's what you should do instead:
1. Cool the burn immediately: Run cool (not cold) water over the burn for 15-20 minutes.
2. Remove any jewelry: If you have any jewelry on the affected hand, remove it before the area starts to swell.
3. Cover the burn: Apply a clean, dry bandage to protect the burn from infection.
4. Elevate the hand: Keep the hand elevated above your heart to reduce swelling.
5. Seek medical attention: For burns that are larger than 3 inches, deep, or involve the face, hands, feet, or genitals, seek immediate medical attention.
Remember: Always consult a healthcare professional for any burn injury. They can provide appropriate treatment and prevent further complications.
