Part 5 First aid treatment Ex. 4--discussion 1.Wrong: Sam should not have broken the blisters because the burns could become infected. He should have poured cool water, not icy water on the burn. The correct treatment for a second degree burn like Sam’s is described in No 2 of the exercise. 2.Right 3.Wrong: Mr Casey was right to take his wife’s blouse off but he should not have picked bits of blouse off the burn.
