What is accessibility and universal design?
Accessibility refers to the extent to which products, systems, and environments can be used by people from a population with the widest range of characteristics and capabilities.1
Universal design is the design of products, systems, and environments to be usable by all people without the need for adaptation or specialized design. Examples include curb cuts, automatic doors, and zero-step entrances to buildings.2
Why is accessibility important in standards development?
Accessibility is important in standards development because one-size-fits-all solutions rarely meet every person’s needs, but the incorporation of accessibility requirements into safety standards can support the development of systems that accommodate more users, including those with disabilities.
How is ULSE addressing accessibility when developing standards?
- Identifying accessibility needs — ULSE is conducting focus groups with people who have disabilities, to identify specific needs or hazards that can be addressed through standardization.
- Gathering stakeholder recommendations — ULSE is convening technical experts and people with lived experience to provide recommendations on how to address needs.
- Improving impact of existing standards — ULSE is revising its standards to improve the safety impact for people with disabilities.
How do UL standards consider the needs of people with disabilities?
We are analyzing our standards catalog to identify opportunities to provide construction and performance requirements that help make products and systems more accessible to people with disabilities. One example is the inclusion of low-frequency alarms for smoke and fire alarm systems. These low-frequency alarms are more effective at alerting people with hearing impairments, as well as sleeping persons, children, and the elderly. Several UL fire safety related standards include requirements for both low frequency and high frequency alarms:
- UL 217, Smoke Alarms
- ULC S531, Smoke Alarms
- UL 268/ULC S529, Smoke Detectors for Fire Alarm Systems
- UL 464/ULC S525, Audible Signaling Devices for Fire Alarm and Signaling Systems, Including Accessories
