Final answer:
Artificial respiration should be started immediately on a train operator who has suffered an electric shock by coming in contact with the third rail if he is unconscious and not breathing.
Step-by-step explanation:
Artificial respiration should be started immediately on a train operator who has suffered an electric shock by coming in contact with the third rail if he is unconscious and not breathing.
The third rail in train systems is the electrified rail that provides power to the trains. When a person comes in contact with the third rail, they can suffer from an electric shock, which can cause various injuries including cardiac arrest and respiratory failure.
To perform artificial respiration on the train operator, follow these steps:
Ensure your safety by not coming into direct contact with the electric source.
Check the person's responsiveness by gently tapping their shoulder and asking if they are okay.
If the person is unresponsive and not breathing, immediately call for emergency medical help.
Place the person on their back on a flat surface.
Tilt their head back slightly to open the airway.
Pinch their nose closed and cover their mouth with yours, forming a tight seal.
Blow into their mouth for about 2 seconds, watching their chest rise.
Remove your mouth and allow the person's chest to fall.
Repeat the breath every 5 seconds.
Continue artificial respiration until emergency medical help arrives or the person starts breathing on their own.
