Depends on the brand you choose. Some medical alarm system companies come with free installation charges.

it's good that you're asking as some basic sensible first aid advice can make a difference to how burns heal.

Before you treat burns you need to figure out the severity; whether they are first, second or third degree burns. This will depend on the extent of the tissue damage.

First degree burns are superficial and don't blister. The burn may be red and swollen. Run the affected area under cool water and you can put some silver sulphadiazine on it to help the healing.

Second degree burns may turn white on touch and blisters may develop. The burns extend to the middle skin layer. To treat; gently clean and dry the area. Apply antibiotic cream and seek medical treatment immediately.

Third degree burns damage all 3 skin layers and can be very dangerous and even life threatening if they affect over 90% of the body. Treatment involves immediate medical care, fluids will be needed to deal with dehydration and possibly oxygen.
