Which way should a hospital corridor door swing — and why did the inspector just reject your submittal? Opening direction and leaf configuration are among the first decisions on a door schedule, and among the most expensive to change after frames are welded into partitions. Getting them right requires reconciling circulation logic, egress code, accessibility, and pressure-control requirements.

6.1 Handing: the language of swing doors

Door handing describes both the direction of swing and the side on which the leaf is hinged. The dominant North American convention determines handing from the outside of the room — the side from which you pull (not push) the door open, or for corridor doors, the corridor side:

  • Left-hand (LH): hinges on the left, leaf swings away from you.
  • Right-hand (RH): hinges on the right, leaf swings away from you.
  • Left-hand reverse (LHR) / right-hand reverse (RHR): the leaf swings toward you.

European practice (DIN 107, EN 12519 terminology) instead names the hinge side as seen from the pull side, so a DIN "left" door is not always identical to an ANSI "left-hand" door. Common mistake #1: mixing the two conventions on an international order. Always confirm handing with a plan-view diagram, not abbreviations, and state which standard the notation follows.

Handing is not just about the leaf. It determines lock backset orientation, closer arm geometry, coordinator placement on pairs, and which leaf of a double door is active. Steel door hardware is often non-reversible — a mortise lock ordered LH cannot be flipped to RH.

6.2 Inward vs. outward opening

Inward (into the room) is the default for small rooms — offices, patient rooms, storage — so the open leaf does not obstruct the corridor. Outward (into the corridor / direction of escape) is required where codes demand it and preferred in several functional situations:

  • Egress: IBC Chapter 10 (Section 1010.1.2) requires doors to swing in the direction of egress travel where the occupant load is 50 or more (Group H occupancies: any load). NFPA 101 contains an equivalent rule. Corridor doors serving assembly spaces, large labs, or pharmacies therefore swing outward.
  • Pressure control: in negative-pressure isolation rooms an inward-swinging door is pulled tighter against its seal by the pressure differential; in positive-pressure cleanrooms the reverse holds. See Chapter 10 for how this interacts with gasketing.
  • Hygiene: doors into scrub areas and sterile cores often open away from the user so they can be elbow- or sensor-operated without touching the pull handle on the clean side.

Trade-off: an outward-swinging corridor leaf is an obstruction and a strike hazard in narrow corridors. Mitigations include recessed door pockets, vision panels, swing-clear hinges (Chapter 7), or switching to a sliding door.

6.3 Single-leaf vs. double-leaf

Configuration Typical clear width Use
Single leaf 700–1200 mm Offices, patient rooms, WCs
Unequal pair (active + inactive) 1200–1800 mm Patient rooms needing bed access, equipment rooms
Equal pair 1500–2400 mm Corridors, operating suite entries, logistics routes

Pairs add an inactive leaf with flush bolts, a coordinator to sequence closing, and an astragal or meeting-stile seal — each a potential failure point for fire latching, air leakage (Chapter 10), and cleanability. A wide single sliding leaf often achieves the same clear opening with fewer interfaces, which is why equal-pair hinged doors are increasingly reserved for egress-rated routes where codes restrict sliding doors.

6.4 Sliding directions

Single-slide, bi-parting, telescopic (multi-panel), and hermetic sliding layouts each impose different requirements:

  • Track length: a single slider needs clear wall equal to the leaf width on the open side; telescopic systems halve this at the cost of a more complex drive (Chapter 8).
  • Direction of slide relative to traffic flow matters at corridor junctions — an opening leaf should not sweep across an intersecting route.
  • Egress limitation: power-operated sliding doors must either be on the required egress route with full redundancy per ANSI/BHMA A156.10 and EN 16005 provisions, or a hinged egress door must be provided nearby. Common mistake #2: placing the only exit from an OR as an automatic slider without a swing-door alternative.

6.5 Accessibility and circulation

Accessible routes require minimum clear widths (32 in / 815 mm under ADA; 800 mm under many EN-based national rules), maneuvering clearances on both pull and push sides, and maximum opening forces (interior doors: 5 lbf / 22 N under ADA; EN 17210 gives similar limits). Fire doors with closers frequently exceed these forces — the accepted solution is a low-energy power operator (ANSI/BHMA A156.19) rather than weakening the closer.

Practical checklist

  1. Confirm the handing convention (ANSI vs. DIN) in writing with the supplier; attach plan-view diagrams.
  2. Check occupant load → swing direction per IBC 1010.1.2 or local egress code.
  3. Match leaf configuration to the largest item that must pass (bed, trolley, imaging equipment) plus 100–150 mm margin.
  4. Verify the sliding door's egress status before deleting hinged alternatives.
  5. Confirm opening-force compliance with closers installed, or specify A156.19 low-energy operators.
