Glossary Terms for Physical Accessibility

A

Access aisle

An area next to an accessible parking space set aside for the person using that parking space. Drivers and passengers use these aisles to enter and exit a vehicle, deploy wheelchair lifts, or transfer from a vehicle to a mobility device. ¹

Accessible

describes a place, object, service, or content that a person with a disability can perceive, use, interact with, or understand. In some countries, “accessible” describes places, objects, services, or content that meet legal standards for accessibility to people with disabilities. ^{2 1 3 4 5}

Accessible means of egress

A continuous and accessible route from any point in a building facility to an exit, refuge area, or public right of way. The routes lead to emergency egress points. ¹

Accessible path of travel

See accessible route

Accessible restroom

See accessible toilet room ¹

Accessible route

A route that provides a consistent connection between different accessible elements. The route must be continuous and uninterrupted, without any objects or obstructions that would interrupt it. There are three types of accessible paths of travel:

Accessible routes from site arrival points

Connect facility entrances and sidewalks, parking, drop-off areas, or transit stops. These are also called accessible paths of travel.

Exterior accessible routes within a site

Connect different facilities or buildings to one another

Interior accessible routes

Connect different points of interest within a facility or building to one another.

In some countries, all accessible routes are called accessible paths of travel. These routes can include circulation paths.^{2 1 4}

Accessible toilet room

Any room with a toilet that meets accessibility standards. These are usually restrooms, but can be part of a restroom facility - for example, if the toilets and sinks are in separate rooms. In many countries, the terms accessible restroom or accessible washroom are more common. ^{2 1}

Accessible washroom

See accessible toilet room.

Alert and signal devices

tools that indicate an emergency or other important event to people present in a building. Common examples include fire alarms, smoke detectors, entrance bells, and door closing warning devices. ² Many regulations specify the need for audible signals that someone can hear and visual signals that someone can see. Audible signals must meet certain sound and frequency requirements. Visual signals must meet certain brightness and frequency requirements. ^{1 2}

Alteration

A temporary or permanent physical change to a building or facility that could affect whether the building is accessible. Common alterations include construction detours, renovations, equipment replacement, refinished floor surfaces, and revised signage. In some cases, alterations can pose obstacles, create protrusions, or lead to a change in level. ^{2 1}

Approach

A route leading to the entrance of a site, building, facility, or element, or a specific fixture or element. An accessible approach meets standards for accessible routes. Approaches to facilities and elements must meet certain standards to be accessible. There are two types of common approach: forward approaches, which allow someone to come directly to an element or site, and side or parallel approaches, in which someone can come such that the element or fixture is to their side. ¹

Assembly area

A part of or an entire building or facility used for gatherings. These areas may be for entertainment, government, educational, or business purposes. Examples include classrooms, courtrooms, theaters, auditoriums, and arenas. Laws in most countries mandate that these areas must be accessible. ¹

Assistive listening device

A portable system used to amplify or distinguish sounds. Many people use these devices to provide additional support beyond a hearing aid or cochlear implant. They are often used together with assistive listening systems. ⁶

Assistive listening system

A system installed in a building or facility that provides amplified audio for people who use hearing aids or other assistive technology. The system connects with the device a person uses to provide amplified, clear sound. The system is connected with a microphone. Systems are named for their technology. The most common system is an audio induction loop; FM radio devices, Bluetooth devices, and infrared headset systems are also in use. ^{2 1 6 5}

Audible signal

See alert and signal devices.

B

Check-out counter

See counter

Circulation path

An indoor or outdoor path for pedestrians. Examples include sidewalks, hallways or corridors, elevators, ramps, and stairs. In some countries, these are called pedestrian routes. A circulation path can be part of an interior or exterior accessible route. ^{2 1}

Clear line of sight

The ability of someone to see an event or object they wish to watch without anything blocking it. Examples of where this applies include performance venues, signs, and other wayfinding cues or indicators, such as vehicle controls and art exhibit layouts. ^{1 2}

Clear floor space

See clearance

Clear ground space

See clearance

Clear opening

A space in which there are no protrusions. Accessible routes and door openings must have clear openings of a minimum width. ¹

Clearance

This term is used in two separate ways.

• A clear floor or ground space in front of elements, fixtures, doors, controls, and other features of a building, facility, or site. Clearances help people with disabilities approach, use, and leave these features. Clearances also help people who use wheelchairs and other mobility devices turn or maneuver in a space. In some countries, regulations distinguish clear floor space, clear ground space, and turning space, as well as transfer spaces. ^{2 1}
• Space under, above, or around an element that protects people from bumping into surfaces, especially if those surfaces can harm them. Common forms include headroom or vertical clearance, knee clearance, and toe clearance. These help people avoid bumping or hurting their heads, knees, and feet. ^{2 1}

Common use

Any private space or path that is meant to be used by multiple people. Examples include shared office kitchens, classrooms, conference rooms, and workplace hallways. ¹

Control

See operable parts

Counter

E

Edge barrier

See edge protection.

Edge protection

A raised feature at the edge of a change of level, path, ramp, or platform. This tool helps people with mobility disabilities not fall, and people who use canes to navigate to find edges. Some types of edge protection are called edge barriers, flared sides, or flares in some countries. ^{2 1}

Element

A part of a building, facility, or site which people use. For example, doors, appliances, and kiosks are elements. ¹

Elevator

• The landing by the elevator
• Elevator doors and call buttons (which may be kick buttons)
• The elevator car, in which people travel
• Operable parts (controls or buttons) used in the elevator

Elevators that are used in residences, closed areas, and public spaces must meet slightly different standards in some countries. ¹

Skid resistance

See slip resistance

Slip resistance

Describes a floor surface that reduces the risk of people and their mobility aids from losing grip on the floor and falling. These surfaces are made of materials that provide friction to the foot or mobility aid. Slip-resistant surfaces are also configured to prevent slipping, for example, through texturing. Hazards, such as spills of water and oil or protrusions, can affect slip resistance. Different levels of slip resistance are required in different contexts. The slip-resistant surface must also be stable. Some countries use the term “skid resistant.” ^{2 1}

Slope

The incline of a surface such as a ramp, curb ramp, walkway, or corridor. You can measure slope by using a ratio, such as 1:12. The ratio measures the amount of vertical rise over a length of horizontal distance. For example, a rise of 1 centimetre over 12 centimeters of length would produce a ratio of 1:12. There are two types of slope:

• Cross slope: A change in slope that is perpendicular to the direction of travel. This change is called perpendicular slope in some countries.
• Running slope: parallel to the direction of travel.

In some countries, the term pitch is used for the slope of ramps and stairwells. Stair pitch is the angle, or slope, at which stair steps ascend or descend. Slope is often measured alongside rise. ^{2 1 3 4}

Space

A definable area. Examples include a room, toilet room, hall, or lobby. ¹

Stable surface

See stable, firm surface

Stable, firm surface

These surfaces are generally hard and continuous, such as wood, concrete, or vinyl planking. In some countries, these are also called stable surfaces. Such surfaces must also be slip resistant. ¹

Stair lift

See platform lift.

Stair nosing

The extended front edge of a step on a staircase. These both protect the staircase and help blind people detect the edge. ²

Step-free access

Describes a route or facility that does not require steps or stairs to enter or use. Surfaces may be level or flat, or include ramps, elevators, or lifts. This approach supports people who use mobility devices. The term barrier-free access is more common in some countries. ^{1 5}

Story/storey
