Its primary purpose is to provide testable success criteria covering visual, auditory, motor, cognitive needs. Key approach: layered model with stable normative requirements separate from evolvable techniques.
Key Components
- **POUR principlesPerceivable, Operable, Understandable, Robust.
- 13 guidelines, ~80 success criteria at A/AA/AAA levels.
- Informative techniques, failures, understanding documents.
- Conformance via full pages, complete processes, accessibility-supported tech, non-interference.
Why Organizations Use It

- Planning (hazards, risks, objectives)
- Implementation (training, controls, emergencies)
- Checking (audits, incidents, measurements)
- Management review/continual improvement Aligns with ISO 45001; ~6 hazard categories; voluntary certification via SCC-accredited bodies.
Why Organizations Use It
Meets legal duties via incorporation-by-reference; demonstrates due diligence; reduces risks/fines. Strategic: accelerates policy, builds trust, aids procurement/market access, lowers insurance costs.
Implementation Overview
Phased: gap analysis, policy/training, audits, integration. Suits mid-large orgs in manufacturing/construction/energy (Canada/global). Involves worker participation; certification optional but recommended.
