What is door hardware release?
Door hardware release of electrically locked egress door assemblies. Doors utilizing this locking arrangement are locked with an approved electrical locking system that is released by door hardware that is affixed to the door leaf itself.. The door leaf is typically held locked to its frame with an electromagnet. The biggest difference between this type of locking arrangement and that described in condition (2) is the location of the releasing hardware (affixed to the door leaf vs sensor). Doors with this arrangement operate very similarly to a traditional door assembly.

Is it safe to leave a building during an emergency?
Leaving a building or relocating to another point of safety during an emergency should not present obstacles to occupants trying to do so. One of the greatest impediments to this free egress is an unexpected and noncompliant locked door. Fundamental door operation requirements ensure that doors are readily openable, easy to operate and available for use when the building is occupied. However, when security needs also dictate a need for additional protection, balancing that security need with additional life safety measures will help to ensure occupants continue to be offered safe and reliable means of egress during emergency situations.

How far does a door swing into a required egress?
When a door swings into the required egress width, the encroachment of the door into the required width must be considered. According to the IBC, a door may not reduce the required egress width by more than one-half at any point during the door’s swing. For example, if a corridor is 5 feet wide and the required egress width is 5 feet, a 3-foot door swinging into that corridor would encroach too far into the required egress width, because at 90 degrees the door will obstruct more than half of the required egress width. These restrictions do not apply to doors within individual dwelling units or sleeping units of R-2 and R-3 occupancies, which would include apartments, hotels, dormitories, and child/adult care facilities.
