The use of the thermal lance is unrealistic. A skilled operator would check the gases are on and at the correct pressure before ignition, rather than relying on a third party to "turn on the oxygen" at the cylinder. As both the oxy-acetylene torch and the lance have shutoff valves, the operator could isolate all the gases if required. Since Bambas was the expert on drilling / tunneling, it is unlikely he would have allowed anyone else to operate the lance, as they would have had no experience of it.
