While frying snacks it bursted causing hot oil to spill over my wife's hands causing burn injury.. pl guide me for appropriate treatment considering the degree of burns

- For a mild burn (first-degree), rinse with cool water for 10-15 minutes and apply a soothing lotion. For moderate burns (second-degree), cover with a clean, non-stick bandage and seek medical attention immediately. If the burn is severe (third-degree), avoid touching it, keep the area elevated, and go to the emergency room right away.
