  5. Doors are “appliances” • 36" door requires about14 square feet to open 180° • Hardware • Privacy Locks • Passage Locks • No door may cover a light switch • Light switch is nearly always near the doorway on the wall on knob side of the doorway • Breaking a door against the jamb takes approximately 50 times the force as against the latch!

  6. Exterior Doors—Business • Part of an exit system • Must be clearly marked • If occupancy load of ≥50 must: • All doors that are part of the system must swing toward the outside (Field expedient compass) • Be equipped with nonmanipulable handles(“panic locks”) 36-48" InsideOutside

Exterior Doors—Residence • All houses require two exit doors • Front “entrance” door leaves (>95%=36 wide“) • Most are single doors, multiple doors look for: • Peephole & Doormat—identify moving leaf • Mail slot—in fixed leaf • Rear door may be hinged (~30-32"), but also French or Sliding Patio Doors 36-48"1-3/4" solid core InsideOutside
