First, slipped his grease-colored tubes, then sealed with low-melting solder. Running once past this point, I noticed that there was no on oil line is not set, this inscription is not visible. I realized that being prepared is a serious diversion, more important than that to which I was involved. In one of the night shift at the beginning of March 1942 the Germans staged a trial run Krupp and reduced turbine generator power of 1000 kW. After repairing the turbine, according to the instructions, it was necessary to listen at full speed, without covering the turbine casing with thermal insulation.

Heated with saturated steam cylinder of the turbine has a temperature above 300oC. A German guard only then did that leave an observation platform and was hiding in the principal's office to escape the scorching heat in the engine room. In the night of those days were on duty mechanic Privalov turbines, electrical N. , electrician N. Yarotsky, shift engineer heating engineer Ermak (in the boiler room).

Choosing the moment when the guard was away, Privalov sharply raised pressure oil pump, perhaps something pierced with a sharp place the inscription, soldered fusible solder, or it is itself soldered to the heat. With space on the oil line, which was the inscription, raising the jet oil, which began to pour corps bare hot cylinder, floor, wooden stairs, walls, painted with oil paint. Oil, hitting on a hot cylinder of the turbine, suddenly ignited. The fire covered the entire space machine room.
