“Always guarantee your own safety before helping someone in a first aid situation! It might seem obvious, but it is overlooked way too often. For example: when someone is unconscious in a closed space and there are no direct clues to the cause, always assume there is CO and the room isn’t safe to enter. Try to ventilate the room and get the person out of there as quick as possible, but don’t risk your life by staying in there for too long!”
