No one has compared "man-on-the-tracks" to confined space rescue yet. Before you attempt it you must protect yourself or you risk creating more victims or fatalities. Chemists know all about it because of the risk of poisonous gas. If I saw someone collapsed in front of their fume hood not knowing what was going on I wouldn't even try to pull the fellow out without breathing gear, even if it was a friend or colleague. This is left to trained personnel, that is the fire brigade. There was this incident about twenty years ago at my old university where they dispensed liquid nitrogen in a basement that had no oxygen sensor (!). The ventilation had failed, and a student who came to fill up his dewar fell unconcious for lack of oxygen and couldn't turn off the tap. A second student tried to pull him out and became unconscious as well. It took number three to pull out numbers 1 and 2. Result: one dead, one disabled. There is bravery, and there is insane heroics. Pulling a fellow bent on suicide off a train track is the second kind. It takes discipline not to do it.
