Burns from the galley, engine, sun and electricity

Hold a burn or scald under cool running water for 20 minutes, as soon as you can, and within 3 hours of the injury. If the boat has no running water, use cool bottled water or a wet towel. While you cool, take off clothing and jewellery near the burn unless it is stuck to the skin.

NHS inform in Scotland says at least 10 minutes for a thermal burn, or until the pain eases. This course uses the longer 20-minute cool from the NHS England page.

When the burn has been cooled, lay cling film over it. Do not wrap the film around the limb. Do not use creams, oils, butter, or sticky plasters. Do not burst blisters.

Get emergency help if the burn is very large or deep, if it is on the face, genitals, or bottom, or if a chemical or electricity caused it.

For a chemical on the skin, rinse with cool running water for at least 20 minutes and do not get the chemical on yourself.

Cooling a large burn can itself chill a child, an older person, or anyone else. If that risk appears, stop cooling long enough to avoid hypothermia.
