We need to make sure all ADA commercial doors comply with the Following:
a) Swing of Doors should be: OUT swing
b) Threshold:
If provided, must not exceed 1 ⁄ 2 inch height for swing doors or 3⁄4 inch in height for exterior sliding doors.
Changes in level up to 1⁄4 inch can be vertical and do not need an edge treatment.
Changes in level between 1⁄4 inch and 1⁄2 inch must have a beveled slope equaling1:2.
If the changes in level are greater than 1⁄2 inch, the threshold must be equipped with a ramp. The floor or ground surface within the maneuvering clearances at the doorway must not have a slope steeper than 1:48.
c) Hardware height: Door handles, pulls, latches, locks and other operating devices shall be installed 34 inches (864 mm) minimum and 48 inches (1219 mm) maximum above the finished floor. Locks used only for security purposes and not used for normal operation are permitted at any height
Hardware:
The standard height of the panic bar is 41 inches above the floor, though the height varies among schools and daycares.
Handles, pulls, latches, locks and other operating devices on accessible doors must have a shape that is easy to grasp with one hand and does not require tight grasping, tight pinching, or twisting of the wrist to operate.
Lever-operated mechanisms, push-type mechanisms, and U-shaped handles are acceptable designs.
When sliding doors are fully open, the operating hardware must still be exposed and usable from both sides.
Hardware must be mounted no higher than 48 inches above finished floor.
d) Door size:
Width and Height Requirements:
By ADA standards, the clear width of a door opening must be a minimum of 32 inches and a maximum of 48 inches. This clear width measurement is taken between the face of the door and the stop of the frame with the door open to 90 degrees (Figure A).
Figure A
The clear height of a door opening must be a minimum of 80 inches (Figure B).
Figure B
e) Door Surface :
If there are any projections on the face of the door, they must be no lower than 34 inches above the floor or ground and must not extend more than 4 inches from the surface of the door (Figure C).
Figure C
Door Bottoms rail :
surfaces within 10 inches of the floor or ground must be a smooth surface on the push side extending the full width of the door. Any parts creating a horizontal or vertical joint on the surface shall be within 1⁄16 inch in depth. If cavities are created by added kick plates they must be capped.
- f) Closer and Hinges:
The closer and hinges selected should allow to comply with the closing and opening requirements see below:
Closing Speed (ADA Guidelines 4.13.10)
If a door is equipped with an automatic closing device (door closer), then the sweep range of the closer must be adjusted so that from an open position of 70 degrees, the door will take at least 3 seconds to move to a point 3 inches from the latch, measured to the leading edge of the door
Door opening force.
The opening force for interior side-swinging doors with-out closers shall not exceed a 5-pound (22 N) force. For other side-swinging, sliding and folding doors, the door latch shall release when subjected to a 15-pound (67 N) force. The door shall be set in motion when subjected to a 30-pound (133 N) force. The door shall swing to a full-open position when subjected to a 15-pound (67 N) force. Forces shall be applied to the latch side.
