Importance of Door Specifications
Unlock Audio Lesson
Today, we’ll talk about why it's crucial for doors to have the right specifications, especially width and clearance. Can anyone tell me what the minimum door width should be for accessibility?
Isn’t it 800 mm?
Close, but not quite! The minimum clear opening width is **900 mm**. This ensures that wheelchairs can pass through easily. Why do you think this minimum is so important?
So that everyone can enter without assistance?
Exactly! This way, individuals with mobility challenges can maintain their independence. Let's also remember that on the pull side of the door, the space should be a minimum of **1200 mm x 1200 mm** to avoid any jams. Can anyone summarize what we covered?
The door should be at least 900 mm wide and 1200 mm on the pull side!
Perfect!
Door Handles and Hardware
Unlock Audio Lesson
Next on our list is door handles and hardware. Why do you think lever handles are preferred over knobs?
Because they’re easier to use?
Spot on! Lever handles allow easier operation for people with limited hand strength. It's also important that our handles are installed at **900 mm to 1100 mm** from the floor. Why might that height be critical?
So that everyone, including kids and shorter people, can reach them?
Yes! Furthermore, handles should allow one-handed operation without any tight grasping. Can anyone recall why this is particularly advantageous for us?
It makes them more accessible to people with disabilities!
That's exactly right! Well done.
Vision Panels and Safety
Unlock Audio Lesson
Now, let’s talk about vision panels. Why are they important in door design?
To see if someone is coming?
Absolutely! They help prevent collisions. The bottom edge of these panels should not be more than **900 mm** from the floor. Can anyone think of how this specification helps users?
It allows wheelchair users to see through it!
Exactly! And we also need to ensure that the panels have high-contrast warning strips if they’re frosted or obscured. Can someone tell me why?
To prevent accidents, right?
Right again! Safety is key to accessibility!
Mechanical Requirements: Force and Operation
Unlock Audio Lesson
Let’s move on to door closers and the force needed to open them. Why is it important that the opening force does not exceed **22 N**?
So that anyone can open the door, even if they’re not strong?
Exactly! It's crucial that doors are manageable for everyone. Additionally, automatic doors should remain open long enough for safe passage. Why is that critical?
Because some people might need more time to get through?
You got it! And they can use motion sensors to assist in ensuring the door opens automatically. To sum up, can anyone rephrase what we learned today about door operation and access?
Doors should be easy to open and stay open long enough for everyone to pass safely!
Well summarized!

Doors play a crucial role in maintaining accessibility within buildings. This section highlights key specifications, including minimum width, clearance, and hardware requirements crucial for individuals with disabilities, ensuring that all doorways are safe and easy to navigate.
Detailed
Doors: Width, Clearance, and Hardware
Understanding the specifications for doors is vital in creating an accessible environment for all. This section emphasizes the following key aspects:
5.1 Width and Clearance
- A minimum clear opening width of 900 mm is necessary for easy wheelchair access.
- In double-leaf doors, at least one leaf should maintain this minimum width.
- A clear space of 1200 mm x 1200 mm must be provided on the pull side of the door to facilitate smooth operations without obstruction.
- The swing of the door should not diminish the effective width available for passage, ensuring users can maneuver without hindrance.
5.2 Handles and Hardware
- Lever handles are recognized as the best option in favor of knobs, as they are easier to operate for users with limited hand strength.
- The height for door handles should be positioned between 900 mm to 1100 mm from the ground to accommodate different user needs.
- Hardware should be designed to allow operation with one hand, negating the need for tight grasping, pinching, or twisting.
5.3 Vision Panels
- Transparent doors are required to have vision panels that ensure visibility and reduce the risk of collision.
- The bottom edge of the vision panel should not exceed 900 mm from the floor to cater to individuals of varying heights, particularly wheelchair users.
- Any frosted or obscured glass should prominently feature high-contrast warning strips to alert users to the presence of a door.
5.4 Door Closers and Force
- The force required to open the door should be no more than 22 N to ensure it is manageable for all users.
- Automatic doors need to be designed to stay open long enough for safe passage, supplemented by motion sensors or push plates to assist in accessibility.
This section underscores the importance of designing doors that support autonomy for individuals with disabilities, ensuring compliance with regulatory standards while fostering inclusivity.

• Minimum clear opening width: 900 mm.
• In double-leaf doors, at least one leaf should have a clear opening of 900 mm.
• Minimum space on the pull side of the door: 1200 mm x 1200 mm.
• Swing of the door must not reduce the effective width.
Detailed Explanation
This section emphasizes the importance of door width and clearance in ensuring accessibility. The minimum width for door openings is set at 900 mm to accommodate wheelchair users comfortably. For double-leaf doors, one leaf must also meet this width requirement. Additionally, there should be at least a 1200 mm x 1200 mm clear space on the pull side of the door to allow ample maneuverability. Lastly, the door's swing should not obstruct the effective width, ensuring that the doorway remains accessible even when the door is open.
Examples & Analogies
Imagine trying to enter a room with a bulky wheelchair. If the door's opening is narrow, it can be frustrating and even impossible to pass through. A wide door, akin to having a spacious entrance to a cafe, makes the experience seamless and pleasant.
