Sanjay is a sous chef at a very upscale new restaurant in Los Angeles. Currently, he is in charge of the pasta station, which means that he regularly works with a hot stovetop and boiling water. Earlier today, he accidentally splashed scalding hot water on his forearm and suffered a burn. The burn quickly turned deep red and began to swell, with blisters filled with fluid forming soon after. Sanjay soaked his burn in cool water for 30 minutes, then applied antibiotic cream, and covered it with a clean dressing. What type of burn does Sanjay most likely have and did he treat it correctly?
