Importance of Ramps in Accessibility
Unlock Audio Lesson
Today, we're focusing on ramps and their critical role in accessibility. Can anyone tell me why ramps are especially important for wheelchair users?
They help people in wheelchairs to enter buildings where there might be stairs!
Exactly! Ramps provide a way to enter without barriers. Now, who can explain what the maximum gradient for ramps should be?
Is it 1:12?
Correct! A 1:12 gradient is the maximum, but there's an even better option. Who can remember what that is?
1:20 is the preferred one!
Great! Now, let’s summarize: Ramps must not exceed a 1:12 gradient, but preferring 1:20 is ideal for user comfort. Ramps are crucial for accessibility.
Design Specifications of Ramps
Unlock Audio Lesson
Let’s look at the specifics of ramp design now. How wide should a ramp be?
It should be at least 1200 mm wide.
Exactly! A minimum width of 1200 mm is essential to allow safe passage. What about handrails? Why are they important?
They provide support for users as they go up and down the ramp.
Correct! Handrails on both sides of the ramp are crucial for safety. Can anyone tell me the two height levels at which handrails should be placed?
750 mm and 900 mm.
Well done! To recap: ramps must be at least 1200 mm wide, have a maximum gradient of 1:12 (or 1:20 preferably), and feature handrails at 750 mm and 900 mm.
Rest Landings and Their Importance
Unlock Audio Lesson
Landings are also an integral part of ramp design. Who can remind us how often we need them along a ramp?
Every 5 meters!
Absolutely! Landings should be placed every 5 meters. Why do you think that is important?
It gives people a place to rest if they get tired going up the ramp.
Correct! They allow users to pause and navigate comfortably. Let's summarize: landings enhance usability and safety on ramps by providing rest points every 5 meters.

The section outlines key specifications for ramp design, including gradient, width, landings, and handrail requirements, emphasizing the importance of accessibility in public spaces for individuals with disabilities.
Detailed
Ramps - Detailed Summary
In this section, we explore the crucial design specifications for ramps within wheelchair-friendly facilities. Ramps serve as vital access routes for individuals with mobility challenges, ensuring they can navigate public spaces safely and effectively.
Key Specifications
- Maximum Gradient: The steepest approved gradient for ramps is 1:12, although a gradient of 1:20 is preferred for enhanced safety and ease of navigation.
- Width: Ramps should have a minimum width of 1200 mm to allow comfortable passage, accommodating wheelchair users and caregivers.
- Landings: Landings are essential for rest and safe navigation; they should be installed every 5 meters to break the ramp's long stretches.
- Handrails: For user security, ramps should feature handrails on both sides, positioned at two height levels: 750 mm and 900 mm. This dual height accommodates various user preferences and physical abilities.
Significance
The design and implementation of ramps are foundational to an inclusive environment, reflecting the principles of Universal Design. Properly designed ramps ensure that public facilities are accessible to all, promoting dignity and independence for persons with disabilities.

• Maximum gradient of 1:12 (preferably 1:20).
Detailed Explanation
The ramp's gradient refers to how steep it is. A gradient of 1:12 means that for every 12 units of horizontal distance, the ramp rises by 1 unit vertically. A gradient of 1:20 is even gentler, making it easier for wheelchair users to navigate. The gentler the slope, the less physical effort is needed by users, enhancing accessibility.
Examples & Analogies
Imagine pushing a stroller up a hill. If the hill is very steep (like a 1:12 gradient), it would be very tiring and challenging. A less steep hill (like a 1:20 gradient) would be much easier to manage, just like a ramp for wheelchair users.
Width of Ramps

• Width: Minimum 1200 mm.
Detailed Explanation
The minimum width of the ramp must be 1200 mm to ensure that there is enough space for wheelchair users to maneuver comfortably. This width also allows for someone to assist the person in a wheelchair without feeling cramped or at risk of falling off the sides.
Examples & Analogies
Think of a one-lane road vs. a two-lane road. A one-lane road can only accommodate one vehicle, leading to traffic jams, whereas a two-lane road can manage two vehicles moving side by side, making the traffic flow much smoother. Similarly, a wider ramp allows better movement for users.
Landings

• Landings every 5 meters for rest.
Detailed Explanation
Landings are flat areas on the ramp where users can rest. The requirement for landings every 5 meters helps prevent fatigue for prolonged use. It offers users the opportunity to take a break, ensuring they do not become overwhelmed when navigating longer ramps.
Examples & Analogies
Consider a long staircase without any landings. Climbing it would require a lot of stamina, and you might need to stop frequently. Having flat landings every few steps would allow you to pause and catch your breath, making the journey manageable.
Handrails

• Handrails on both sides at two levels (750 mm and 900 mm).
Detailed Explanation
Handrails are crucial for providing support and stability to users on ramps. Installing them at two heights, 750 mm and 900 mm, ensures that they can accommodate different users, including those who might be standing or seated in their wheelchairs. This dual-height feature increases safety and comfort.
Examples & Analogies
Imagine walking down a staircase. If there were no handrails, you might feel unsteady. Handrails give you something to hold onto, increasing your confidence. With two sets of handrails at different heights, more people can safely navigate the stairs or ramps.
