Should have been on your hands and knees anyway to stay below the thermal layer.One of the fun things I remember during Boot Camp was ship board fire fighting training. There where large tanks of water that had oil or jet fuel floating on the surface, which would be lit on fire and we had to learn how to put out the fire. But the best part was a room shaped like a compartment on board ship which was full of smoke. We had to enter the room and walk out the other side. Of course somebody always tripped the group and there we were on our hands and knees in a smoke filled room coughing our lungs out.
