procedures take time! some times on the spot decisions need to over ride them before a train comes, an investigation can be made with out putting a suspension on his employment record.
Procedures are there for a reason.... First rule of first aid is DO NOT put yourself or others at risk especially if any others offering help are not trained to deal with the situation...... Fools rush in springs to mind..... One dead could quickly have become 5..
If there was a 3rd rail there's the real risk of the Rescuer getting a 700vdc shock. either off the casualty or by accidental contact with the live rail or been smacked by a express train and spread along 2 miles of track
Problem is in this day and age Staff get moved about the network one week they could be on a basic 2 rail terminal station getting 10 trains a day and a week later they could be covering a minor but on a express line station with 80 trains a day going through at over 100 mph by the time you hear the rails singing its too late with a electrified line adding to the risk.....
Bit old but you can see the real risks especially if you throw a metal wheel chair or crutches into the mess.
Its got to the stage now that many companies train staff NOT TO USE fire extinguishers even on a small fire just to get out of harms way and leave it to the pros..
Recent First aid training i did put this above everything else... Which i put into action when i come across a HGV tanker accident recently.. Before i got near i put the dynamic risk assessment into action for myself and others who had stopped and took charge of the scene until the emergency services turned up drawing on experience from working in the chemical industry, working with moving plant, having a health and safety qualification and HGV repair knowlage not forgetting the first aid training..
