How hot is scalding water?
Water at 60 °C (140 °F) can induce scalding injuries in less than 3 seconds, while it takes 10 seconds to get an injury at 57 °C (135 °F) and 1.5 to 2 minutes in 52 °C (126 °F) hot water. Scalds are generally more common in children, especially from the accidental spilling of hot liquids.
