Treating burns and scalds
Appropriate first aid must be used to treat any burns or scalds as soon as possible. This will limit the amount of damage to your skin.
You can apply the following first aid techniques to yourself or another person who has been burnt.
First aid for burns
Stop the burning process as soon as possible. This may mean removing the person from the area, dousing flames with water, or smothering flames with a blanket. Don’t put yourself at risk of getting burnt as well.
Remove any clothing or jewellery near the burnt area of skin, including babies’ nappies. However, don’t try to remove anything that’s stuck to the burnt skin as this could cause more damage.
Cool the burn with cool or lukewarm running water for 20 minutes, as soon as possible after the injury. Never use ice, iced water, or any creams or greasy substances such as butter.
Keep yourself or the person warm. Use a blanket or layers of clothing, but avoid putting them on the injured area. Keeping warm will prevent hypothermia, where a person’s body temperature drops below 35C (95F). This is a risk if you are cooling a large burnt area, particularly in young children and elderly people.
Cover the burn with cling film. Put the cling film in a layer over the burn, rather than wrapping it around a limb. A clean clear plastic bag can be used for burns on your hand.
Electrical burns may not look serious, but they can be very damaging. Someone who has an electrical burn should seek immediate medical attention at an A&E department.
If the person has been injured by a low-voltage source (up to 220-240 volts) such as a domestic electricity supply, safely switch off the power supply or remove the person from the electrical source using a material that doesn’t conduct electricity, such as a wooden stick or a wooden chair.
Don’t approach a person who is connected to a high-voltage source (1,000 volts or more).
Acid & Chemical burns
Acid and Chemical burns can be very damaging and require immediate medical attention at an A&E department. If possible, find out what chemical caused the burn and tell the healthcare professionals at A&E.
If you’re helping someone else, put on appropriate protective clothing and then:
remove any contaminated clothing on the person
if the chemical is dry, brush it off their skin
use running water to remove any traces of the chemical from the burnt area
