Hello all, I have been browsing this site for a while now but this is my first post. Just wanted to see if you guys could offer any pertinant advise on the following:
I currently keep in my car a decent sized first aid / medical kit which I use both for any incidents at home and when I am out and about at work or doing some other activity (I keep it in the car rather than a cupboard at home because then I know I always have it with me) . I put together the kit myself and I keep it in a medium sized bag and have things divided inside using zip-lock bags It also contains a smaller first aid kit which I can pull out and take with me when I go travelling and so on (specifically a Pyramid Global First Aid Kit see

Also in Glove Compartment I have a small LED head torch and pocket knife.
If people have any advice on items that are either not needed, or additional items that would be required it would be most appreciated. Liekwise any advice at all regarding this sort of kit would be appreciated. Its been used primarily for the occasional sporting injury and the usual cuts and scrapes arround the house, but I wanted it to be capable of being useful in the even of anything more serious (car crash or injuries such as falling off cliffs (which I've previously had to deal with)).
As an additional point I'm looking to create a smaller kit that I can use for camping and other such outdoor activities, so advice on that would be helpful as well.
If it helps I live in the UK, and have done courses in first aid, lifeguarding and sports physio.
