For the escharotomy training, the MSTC guide placed a piece of skin over the mannequin and used a blowtorch to create the burn appearance. Underneath that was a thin piece of foam and Saran wrap with some simulated blood, and underneath that was a yoga mat, which was supposed to be more deeper muscle tissue. This helped to simulate the various layers of tissue you'd encounter as you cut through the skin and the fascia.‰
