The man appears to be as able as any rescue squad, and he should be commended not charged for his efforts. However, for most people the best thing to do in these situations is to not make yourself the victim. That's one of the first things they teach you in emergency training. If you take stupid risks, you can become a victim, and you are no longer contributing to the solution. You're making it worse and putting rescuers at greater risk, because now they have two people to deal with. There's a reason why the elementary training for firefighters is almost 200 hours.
