Why Do We Need Handrail Extensions?

We all know how annoying handrail extensions can be. Architects would prefer having a handrail that fits the aesthetics of their design, however they are confronted with this somewhat restrictive handrail extension driven by compliance. But why?

The Importance of Handrail Extensions in Public Buildings in Australia

Handrails are a crucial safety feature in public buildings, providing support and stability for everyone, especially those with mobility challenges. However, the addition of handrail extensions—where the handrail extends beyond the top and bottom of the stairs or ramps—enhances this safety even further. Here’s why handrail extensions are essential in public buildings across Australia:

Enhanced Safety and Stability

Handrail extensions offer additional support as individuals transition from stairs or ramps to level surfaces. This extra length allows users to maintain their grip longer, reducing the risk of falls and providing a smoother transition.

Compliance with Australian Standards

In Australia, building codes and standards, such as AS1428.1-2009, mandate the inclusion of handrail extensions in public buildings to ensure accessibility and safety for all users. These standards are designed to accommodate the needs of people with disabilities, the elderly, and anyone who might require extra support.

1. Length and Orientation:

• • Top Extensions: Handrails should extend horizontally at least 300mm beyond the top riser of stairs or the end of a ramp.
  • Bottom Extensions: At the bottom, handrails should extend at the slope of the stair flight for a distance equal to at least one tread depth, plus 300mm horizontal extension.

2. Return to Surface:

• • Handrail extensions must return to a wall, guard, or the floor or have a 180’ turn. The turn to the wall, guard or floor is preferred to prevent clothing or objects from getting caught within the ‘hook’. AS1428.1-2009, figure 26 provides ways of terminating the handrail.

3. Protruding Objects Compliance:

• • Horizontal portions of handrail extensions must comply with protruding object requirements to ensure they do not pose a hazard.

4. Continuous Grip:

• • Handrails should provide a continuous gripping surface without interruptions, ensuring users can maintain a secure hold throughout their use.

5. Height and Clearance:

• • The height of handrails should be consistent, and must be 865mm and 1000mm above the stair nosing. There should be a min of 50mm clearance from adjacent surfaces to allow for a firm grip.

Improved Accessibility

Handrail extensions are particularly beneficial for individuals with disabilities. They provide a continuous support system, making it easier for people using mobility aids, such as canes or walkers, to navigate stairs and ramps safely. This inclusivity is vital for creating public spaces that are accessible to everyone.

Increased User Confidence

Knowing that handrails extend beyond the stairs or ramps can boost the confidence of users, especially those who are elderly or have mobility issues. This confidence can encourage more independent movement and reduce anxiety about using public facilities.

Cost-Effective Safety Measure

Implementing handrail extensions is a relatively low-cost modification that can significantly enhance the safety of a building. Compared to the potential costs associated with accidents and injuries, handrail extensions are a wise investment in public safety.

Where handrail extensions are not used correctly

Yes, handrail extensions can be unsightly when they are installed incorrectly. VBC has frequently encountered handrail extensions that protrude into the path of travel, creating both an eyesore and a safety hazard. These extensions can easily cause someone to knock their hip while walking along the passage. Figure 04, although meeting compliance standards, lack safety in design. The preferred option would be to continue the handrail along the glazing, as per Figure 05.

Get handrail extensions to fit into the design from the beginning

The above scenario can be prevented if they are considered from the beginning. Consider including the handrail extension as part of the wall. The below is an image of the stair in the New Victorian Parliament offices
of how the handrail extension continues on the landing of the stair. The extension of the wall allows for the handrail extension and the TGSI (Tactile Ground Surface Indicators) to remain snug with the stairway and not overflow into the path of travel.

In Australian standards, AS1428.1-2009, Figure 26A , it clearly shows that 900mm of length can accommodate for the handrail extensions and TGSI comfortably. Not only is this useful for internal design resolution, but also it must be considered at property boundaries.

In conclusion, handrail extensions are a simple yet effective way to improve the safety and accessibility of public buildings in Australia. By adhering to national standards and prioritizing the needs of all users, we can create safer, more inclusive public spaces.
