Any first aider or medical person Why should I put cling film on a small burn?

[CPandme]

Ive just got a very small burn on my arm putting something in the oven (glove slipped). I’ve run it under the cold tap for a long time, no clothing near it. The NHS guidance says

1. When the burn or scald has cooled, lay cling film over it if you can. Do not wrap the cling film around it.

I don’t have any and cerebral palsy means I’d find it quite hard to apply a dressing. Can anyone explain why it is suggested. Am I ok just to leave it or does it have to be protected and if so how?
thanks

It’s to provide a skin like covering, but I haven’t ever done it for small burns. I think it’s more for a serious or larger burn that’s going to need hospital treatment. I usually apply a final layer of aloe Vera gel if you have any.

It just keeps it clean and should hopefully stop it hurting so much when the air hits it.
If it's a small burn it shouldn't make too much difference though.

Thanks, would be helpful if they had a small explanation including how long to leave it there. - fingers crossed won’t need more treatment. I did the running water then thought I’d have a look at the NHS site and saw it

If it’s a small burn running cold water over it constantly for at least 20 should be enough. As per pp, the cling film is to keep it clean. Don’t put bandages/cloth/paper towel on a burn as the fibres stick to it.

**edit typo

Cling film is to stop air getting to the burn to ease pain and stop infection
you have done the right thing by having it under cold running water for at least 20 mins . Cover with a dressing if needed but don’t use creams or stuff to sooth it

if you are able to take paracetemol or ibuprofen, take one because that makes a massive difference to the pain from a burn.
