Warning Tactile vs Guidance Tactile: What’s the Difference
In public realm design<
Tactile attention indicators, also known as Tactile Walking Surface Indicators (TWSI), are an important accessibility feature required by the Ontario Building Code (OBC) to help visually impaired persons safely navigate buildings and public spaces.
As a leading supplier of tactile products, we at Tactile Solution Canada want to provide a comprehensive overview of what the current OBC says about tactile attention indicators to help architects, contractors, building owners, and property managers understand the code requirements and select compliant products.
The key section outlining standards for tactile attention indicators in the current OBC is Section 188.8.131.52. It states that where a tactile attention indicator is required, it shall conform to the specifications outlined in Sentence (2) and Clauses 4.1.1 and 4.1.2 of ISO 23599 standard for Assistive Products for Blind and Vision-Impaired Persons – Tactile Walking Surface Indicators.
Some key criteria for OBC-compliant tactile attention indicators as per ISO standard 23599 are:
The OBC mandates the installation of tactile attention indicators in the following locations:
Per OBC 184.108.40.206, tactile attention indicators must be installed:
This alerts those with vision impairments that they are approaching a set of stairs.
As per OBC 220.127.116.11, tactile indicators are required:
This prevents people from unintentionally walking off the edge of an elevated or steeply sloped platform.
Per OBC 18.104.22.168, tactile attention indicators must be demarcated:
This warns pedestrians when they are entering a potentially dangerous vehicular travel way.
The OBC requires tactile attention indicators to have truncated dome textures with specific dimensions:
Dome Top Diameter Spacing
These specifications allow the tactile cues to be easily discernible underfoot and detectable with a cane without posing a tripping risk.
