A good thing to have in your first aid kit is burn ointment.
I keep a jar of prescription Silvadene cream in my first aid kit, both at home and in the camper. 
Here's my PSA--
First degree burns leave redness and pain, similar to sunburn. Be careful what you put on a burn--anything Vaseline or oil based can make things worse.  Cool cloths will help take the heat out. I have used wet tea bags on minor burns. An NSAID like Advil or Aleve will help with the inflammation.
Second degree burns leave blisters. If it's confined to one small spot you can probably treat it yourself. Larger than 2", multiple blisters, or blisters on the hands, face or feet should be treated by a doctor. These burns are very painful and can get very infected when the blisters pop.
Third degree burns cause destruction of all 3 layers of skin. Usually turn black, may or may not be very painful because the burn destroys the nerve endings. This is a serious emergency--call 911. This person will be shocky; he needs medical supporte and need IV fluids immediately.
