Will there be lack of oxygen in the elevator when trapped?

In a narrow and sultry elevator, passengers may worry that they will be trapped and suffocated?

Will the trapped elevator suffocate?

National standards have strict regulations on the ventilation of elevators, even if the ventilation system is normal when the elevator is trapped. In addition, the elevator has many moving parts, such as some connection positions, such as gaps between the car wall and the car roof and the connection keys, which are generally enough for people to breathe.
