Perhaps the movie "One Hundred Thousand Fires" can be viewed as a tunnel rescue teaching film.
First, the ventilation method of the tunnel
The most exciting part of the whole movie is that Stallone used a high-power exhaust fan to rescue.
Any tunnel needs ventilation. Because underground facilities often accumulate some harmful gases, ventilation shafts and high-power industrial ventilation fans need to be arranged during design and construction. This allows the air to circulate in the tunnel.
The picture below is a huge industrial ventilating fan.
Second, fracture of the cervical spine
The tunnel officer suffered a fracture of the cervical spine due to an accident. Stallone fixed his head.
According to the Wiseman Survival Manual, when a fracture of the cervical spine is suspected, the neck must be surrounded by a neck circumference or other materials to prevent it from shaking.
Rolled newspapers and towels can be made into a neck circumference, and then tied with a tie or cloth strip.
