Tactile Indicator FAQs

Tactile Indicator FAQs

Tactile Ground Surface Indicators (TGSIs) are installed throughout external and internal public environments.  They are installed at hazard points or locations where directional guidance is necessary for blind or vision impaired pedestrians.  Hazard points include the top and bottom of stairs, ramps, waiting platforms, pedestrian crossings, escalators and any other area deemed to be a potential hazard. Also, it's necessary to install directional tactiles where pedestrians need to be led in a prescribed line of travel. This includes areas such as street crossings and transport access points.

Yes, tactiles need to be installed according to Australian Standards. Why? To maintain consistency so that blind or vision impaired pedestrians can interpret cues provided by tactiles.  Inconsistency leads to misinterpretation and confusion.

The installer needs to have full knowledge of compliance requirements and be able to install according to these set standards.  Locations and substrates vary, and so do the appropriate installation methods.  The right installer will understand these variables and carry out the installation accordingly.

DTAC tactiles are available in:

  • Solid Brass
  • Stainless Steel - 316 marine grade
  • Urethane

DTAC tactiles can be applied to the following substrates:

  • Stone
  • Masonry
  • Timber
  • Vinyl
  • Porcelain
  • Ceramics
  • Glass
  • Metal

 

 

Tactiles are available in different colours due to the fact that a large percentage of vision impaired pedestrians retain some sight. Luminance contrast plays a role in assisting blind and vision impaired pedestrians to detect the presence of tactiles and follow their cues.

The general requirements that apply to tactile indicators:

It shall have the luminance contrast to the base surface as follows:

i) Where the integrated TGSIs are of the same colour as the underlying surface - not less than 30% across its entire area.

ii) Where discrete TGSIs - not less than 45%.

iii) Where discrete TGSIs are constructed using two colours or materials, the raised surface shall have a section that has 60% luminance contrast for a diameter of 24mm to 25mm.... 

Stainless Steel: Silver.

Brass: Gold.

Urethane: Black, yellow, ivory, light grey, silver.

Blacktop: A black urethane centre with a stainless steel surround.

Slip-resistance is very important when it comes to tactiles indicators as they are often placed at potentially hazardous locations. DTAC tactiles conform to slip resistance requirements. The ratings are as follows:

 Types Rating 
 Stainless Steel  R12
 Brass  R12
 ColourMax  R11
Polyresin / Urethane  R12

 

 

Option 1: Carpet

Install DTAC Metal plate to the subfloor and screw fit Tactile DT0116 into the threaded metal fixing plate. Hole punching of carpet may be necessary.

 

Option 2: Carpet Tiles

Up to 6mm thick can be fitted through the surface using DTAC ECOtac DT0130.

 

 

To remain compliant, tactiles need be able to withstand harsh conditions. Poor quality products that degrade quickly under the stress of constant foot traffic and harsh weather conditions, will lose their appearance and effectiveness. DTAC tactiles are designed and manufactured to withstand the harsh Australian conditions. Our products are extremely hard wearing and UV resistant meaning they offer a very long service life.
