Accessibility, egress and fire-rating requirements are reviewed against the drawing set during scope review, because they normally determine device selection before any aesthetic preference does.
01ADA clearance and opening force
Accessible entrances require a clear opening width at 90 degrees, maneuvering clearance on the push and pull sides, hardware operable without tight grasping, pinching or twisting of the wrist, and a mounting height range for that hardware. Interior swing doors are limited to a 5 lbf opening force; exterior doors are governed by the authority having jurisdiction, which is why an operator is often the practical path.
02Closing speed and closer timing
Closers must be adjusted so the door takes a minimum sweep period to travel from the open position to near-closed, and a further interval through the latch. Doors closed too fast fail an accessibility review even when the hardware itself is compliant, so timing is set and verified on site rather than left at factory default.
03Egress and panic hardware triggers
Panic hardware becomes mandatory when the occupancy classification and calculated occupant load cross the code threshold — typically assembly, educational and high-hazard occupancies above the stated load. Egress doors must also open in the direction of travel, unlatch with a single motion, and require no key, tool or special knowledge from the egress side.
04Fire-rated door assemblies
A labeled opening is a system: door, frame, hinges, closer, latching hardware and glazing all have to carry compatible listings, and the label cannot be field-modified. Rated openings require self-closing and positive latching, and any hold-open must release on alarm. Fire-rated glazing is limited by size and by the assembly's rating.
05Safety glazing and marking
Glass in and adjacent to doors is a hazardous location under the code. Lites must be tempered or laminated safety glazing with a permanent manufacturer marking that remains legible after installation — a detail that regularly surfaces on retrofit work where original glass was replaced without documentation.
06Electrified hardware and egress interlock
Access control cannot compromise egress. Electric strikes, mag locks and delayed-egress systems require the correct release scheme, fail-safe or fail-secure selection, fire alarm interface and, where applicable, signage and request-to-exit devices — coordinated with the security scope before the door is prepped.
