For egress doors, what maximum projection into the egress width is allowed?

The maximum projection of 7 inches into the egress width for doors is based on safety and accessibility guidelines that ensure safe passage during emergencies. This standard is established to maintain an unobstructed path for individuals evacuating a building, allowing sufficient space for people to maneuver, especially in crowded or urgent situations.

When a door swings into an egress path, it can reduce the effective width available for movement. Permitting a maximum projection of 7 inches helps to balance the need for door functionality while still prioritizing safety. This dimension has been determined to be minimal enough to allow for free movement while providing adequate clearance, especially in spaces where every inch matters for accessibility, including compliance with the Americans with Disabilities Act (ADA) and building codes.

The other options may reflect less common dimensions that do not align with current codes or safety protocols regarding egress, which is crucial in emergency planning and building design.
