Intent
Intent 1: 
To limit the probability of delays in opening an exit door that does not open in the direction of travel in an emergency situation, which could lead to delays in the evacuation or movement of persons to a safe place, which could lead to harm to persons.
Intent 2: 
To limit the probability that an exit door that does not open in the direction of travel will be difficult to open in an emergency situation if several persons approach it at the same time and the pressure of the group prevents the first person from pulling the door towards them, which could lead to delays in the evacuation or movement of persons to a safe place, which could lead to harm to persons.
Intent 3: 
To limit the probability that a person falling in front of an exit door that does not open in the direction of travel in an emergency situation will obstruct the opening of the door, which could lead to delays in the evacuation or movement of persons to a safe place, which could lead to harm to persons.
Intent 4: 
To limit the probability of delays in the evacuation or movement of persons to a safe place in an emergency situation, which could lead to harm to persons.
