Tactile Indicator Warning PolyStud® Plastic Spigot 35mm Yellow

Frequently Asked Questions

What are tactile indicators?

Tactile indicators are a navigational aid used by the visually impaired to safely make their way around public spaces. They are often in the shape of raised studs or bars, and typically made from a variety of different materials such as plastic polymers or stainless steel. Tactile indicators use the contract between different colours, textures and shapes to provide important information to the visually impaired. A blind or low vision person using a walking stick relies on feeling these changes in texture to safely navigate ramps, stairs, kerbs or pedestrian crossings

Where are tactile indicators required?

According to Australian Standard AS1428.4.1:2009, tactile indicators are required at the top and bottom of stairways, ramps, escalators and moving walks. There are exceptions which are explained in detail in the Australian Standards code.

What are tactile indicators used for?

Tactile indicators are used to provide the visually impaired with directional information and warnings of potential hazards in outdoor and indoor spaces. They are often used near pedestrian crossings, stairways, lifts, ramps and escalators.

How do you install tactile indicators?

The installation of your tactile indicators will depend on the make and model. SureSteel® tactile indicators do not come with an adhesive backing. However, the SureSteel® installation kit and adhesives A27110 are sold separately and can be found on the Seton website. Other tactile indicators require the use of a rotary drill (to drill a hole into the surface it will be stuck onto) and epoxy glue to stick the stud into place. We recommend following the manufacturer’s instructions to get the most out of your tactile indicators.

Are there different types of tactile indicators?

There are two different types of tactile indicators. The first type commonly uses studs or raised dots to inform a blind or low vision person of potential hazards. The second type uses a series of raised bars to provide directional cues to lead a visually impaired person down the safest path. This type is often referred to as a ‘leading tactile’.

Can I use these tactile indicators outside?

These tactile indicators are made from a UV Stabilised Plastic Polymer that is designed to be used outdoors. Stainless steel is another popular material, and can also be used for outdoor applications.

Do tactile indicators need to be yellow?

Although many tactile indicators are yellow, it is not a mandatory colour. According to the regulations of AS1428.4.1.2009tactiles must have a distinct contrast to the background colour of the surface they are attached to. This is to help those who have low vision and rely on coloured tactile indicators to navigate obstacles. While there are online luminance calculatorsavailable to determine this, it is best practice to affix light colours to dark background surfaces.

For Integrated Tactile Indicators, a minimum of 30% luminance contrast is needed. If using discrete or Individual Single-Colour Tactile Indicators, a minimum of 45% luminance contrast is required. Discrete or Individual Two-Colour Tactile Indicators have a mandatory requirement of a minimum of 60% luminance contrast.

Where should I install tactile indicators?

Tactile indicators should be installed wherever they are required to identify a potential hazard, obstacle or information point in an open public space. This is a legal requirement and must be installed in order to comply with Australian Standard AS1428.4.1.2009Examples of potential hazards include stairs or steps, ramps, escalators, level road crossings and embarkation points on public transport.

Are tactile indicators mandatory by law?

Tactile indicators are mandatory in all refurbished and new public buildings. If your facility is being used as a thoroughfare by the general public, or there are collision hazards present, tactile indicators must be used.

What are the coverage requirements for tactile indicators?

Depending on the type of tactile indicator, coverage requirements may differ. According to AS1428.4.1.2009, warning tactiles are required to cover the entire path of travel. On public streets, it is recommended that a width of 600mm is used to allow enough warning to the pedestrian of an incoming hazard. For directional tactiles, a width of 300mm (or 4 bars) is recommended.

Why should I use tactile indicators?

Currently, there are nearly 575,000 people* in Australia living with a visual impairment. With this number set to grow in the coming years, it is important that infrastructure is updated to keep up with this demand. Improving the quality of life for those living with a visual impairment is a great way to make a more equal Australia for all.

What type of tactile indicator is best for my project?

When purchasing tactile indicators, it is important to consider two things: First, are they being used to provide warnings of potential hazards or provide direction. Secondly, what sort of surface will they be applied to? Knowing the answer to both these questions will help you make the right decision. If you’re still unsure, we recommend looking through Seton’s selection guide here.

For outdoor projects, we recommend using tactile indicators made from polyurethane polymer or stainless steel. Both materials are renowned for their wear resistance, and are easy to install on a wide range of surfaces.
