Importance of Handrails
Unlock Audio Lesson
Today, we'll discuss the important role handrails play on ramps and stairs. Who can tell me why handrails are important?
They help people climb stairs safely!
Exactly! Handrails provide necessary support, especially for those with mobility challenges. What heights should handrails be mounted at?
They should be between 850 mm and 900 mm above the ramp or stair!
Good job! This ensures that most users can easily grip the handrails. Remember this height by the acronym HEM—'Handrail Height Makes.' Let’s dive deeper into how we install these handrails properly.
Design Requirements for Handrails
Unlock Audio Lesson
Now, let’s look at the design requirements for handrails. Who remembers where handrails should be placed on ramps?
On both sides of the ramps and stairs!
Correct! Why do we install them on both sides?
So everyone has support, no matter which side they hold onto!
Exactly! And they should extend beyond the ramp or stairs by at least 300 mm. This extension is critical. Remember the mnemonic LEE—'Long Enough Extensions.'
Grip and Shape of Handrails
Unlock Audio Lesson
Let’s discuss the grip shape and sizes for handrails. What should be the diameter for circular handrails?
Between 32 mm and 40 mm!
Great! Can anyone tell me about non-circular handrails?
Their perimeter should be between 100 mm and 125 mm!
Excellent! Remember, we need at least 40 mm of clearance between the handrail and the wall—think of it as 'Room for My Hand'—a memory phrase. Let's wrap up with why these specific shapes matter.
Introduction & Overview
Read a summary of the section's main ideas. Choose from Basic, Medium, or Detailed.
Quick Overview
Standard
This section discusses the importance of handrails as a critical component in ensuring safety and usability for individuals with limited mobility. It outlines design requirements such as placement, continuity, grip shape, and dimension considerations that contribute to enhanced independence and accessibility.
Detailed
Handrails on Ramps and Stairs
Handrails play a crucial role in enhancing the accessibility of ramps and stairs, providing essential support and stability for individuals with balance issues or mobility impairments. The design and installation of handrails must adhere to specified guidelines to ensure safety and usability. This section addresses critical design requirements including:
3.1 Placement
- Handrails must be installed on both sides of ramps and stairs to provide balanced support.
- They should be mounted at a height of 850 mm to 900 mm above the ramp or stair nosing to accommodate most users.
- For added accessibility, a second lower handrail, positioned at 700 mm, can be available for children and shorter individuals.
3.2 Continuity and Extensions
- Handrails must be continuous along the entire length of ramps and stairs, extending at least 300 mm beyond the start and end to facilitate secure gripping.
- The ends of handrails should be turned downward or returned to the wall/floor to prevent clothing from getting caught.
3.3 Grip and Shape
- Handrails should also follow specific dimensions for grip: circular handrails should be between 32 mm and 40 mm in diameter, while non-circular handrails have a perimeter of 100 mm to 125 mm and a maximum cross-section of 45 mm.
- Adequate clearance of at least 40 mm should be maintained between the handrail and the adjacent wall to allow for easy gripping and use.
By following these guidelines, handrails significantly enhance the usability of ramps and stairs, empowering individuals with mobility limitations to navigate spaces with greater independence.

Handrails are critical components that provide support and stability, particularly for individuals with limited mobility or balance issues.
Detailed Explanation
Handrails are essential for safety on ramps and stairs. They help individuals stabilize themselves while using these elements, making it easier and safer for those who may have difficulty maintaining balance.
Examples & Analogies
Imagine walking up a steep hill; having something to hold onto can make the journey much easier. Similarly, handrails act as that supportive element, helping people navigate ramps and stairs without fear of falling.

Must be installed on both sides of ramps and stairs. Mounted at a height between 850 mm and 900 mm above the ramp/stair nosing. A second lower handrail at 700 mm can be added for children or shorter individuals.
Detailed Explanation
For maximum accessibility, handrails should be placed on both sides of stairs and ramps. This allows users to choose the side that feels most comfortable for them. The primary handrail should be at a height of 850 to 900 mm, which is typically comfortable for most adults. Adding a second, lower handrail at 700 mm helps accommodate children or shorter individuals, making it universally accessible.
Examples & Analogies
Think of how a staircase is used in a home. Just like a parent might install a lower rail for their child’s safety, incorporating different heights for handrails ensures that everyone has the support they need.
Continuity and Extensions of Handrails

Handrails should be continuous along the ramp and must extend at least 300 mm beyond the start and end of the ramp or stairs. Ends of handrails should be turned downward or return to the floor/wall to prevent clothing from getting caught.
Detailed Explanation
It is important for handrails to be continuous, meaning they shouldn’t have breaks or gaps along their length. They should extend slightly beyond where the ramp or stairs end, helping users maintain grip and stability even after they have traversed the incline. The ends should be angled downwards or connect back to walls to avoid snagging on clothing, which can be a safety hazard.
Examples & Analogies
Consider holding onto a rope while climbing. If the rope suddenly stops short, you might lose your balance. The extended handrail works the same way, providing a safe and secure hold until you’re fully stable on flat ground.
Grip and Shape of Handrails

Circular handrails: Diameter between 32 mm and 40 mm. Non-circular: Perimeter between 100 mm and 125 mm, with a maximum cross-section of 45 mm. Must have adequate clearance (at least 40 mm) between handrail and wall for gripping.
Detailed Explanation
The design of handrails is crucial for user comfort and safety. Circular handrails should fall between 32-40 mm in diameter for a secure grip. For non-circular shapes, the thickness should be manageable to hold onto. It’s also essential to have enough space between the handrail and nearby surfaces to allow people to grip without feeling cramped.
Examples & Analogies
Picture a bicycle handlebar – if it’s too thin or too thick, it can be hard to hold onto during a ride. Handrails work on the same concept; the right shape and size make sure everyone can hold on safely while they move up or down.
