What construction feature must be part of a door for resident safety when accessing external rooms?

The requirement for a door to swing outward is grounded in resident safety and accessibility considerations. When a door swings outward, it helps ensure that in emergency situations, such as a fire or evacuation, it can be more easily opened from the inside. This design minimizes obstruction within the room and creates a clear exit pathway.

Moreover, an outward-swinging door can help prevent residents from becoming trapped in case of an emergency since it allows for easier egress when seconds count. The design helps in situations where assistance might be needed, as caregivers can pull the door open without needing to navigate around any obstacles that might be present inside the room.

While other features like manual openings or power operations might contribute to accessibility features in different contexts, they do not directly address the critical aspects of safety and quick egress during emergencies. Similarly, mechanisms like automatic locks could complicate exit procedures unnecessarily. Thus, having a door that swings outward is essential for ensuring that residents have safe and unobstructed access to external rooms when necessary.
