The hotel safe passage door can't be opened from the passage to the floor, right?

it's right that the door of the hotel safety passage cannot be opened when it enters the floor from the passage. The hotel security access door is opened in one direction, and it can only enter the passage from the inside of the floor through the security access door, but not from the passage to the floor. This is because the main function of the safety access door is to provide a safe escape route for evacuation and ensure the safety of personnel in case of emergency. Therefore, the one-way opening design of the safety passage door is to ensure that people in the passage escape first.
