1. Our Commitment
Trusted Tech Africa believes that responsible innovation must include accessible technology. We are committed to making SafetyMeter accessible to as broad an audience as possible, regardless of ability or technology. This means we aim to meet the Web Content Accessibility Guidelines (WCAG) 2.1 at Level AA, as published by the World Wide Web Consortium (W3C).
2. Conformance Status
SafetyMeter is partially conformant with WCAG 2.1 Level AA. "Partially conformant" means that some parts of the content do not fully conform to the accessibility standards. We are actively working to address known gaps.
3. Technical Specifications
SafetyMeter relies on the following technologies for conformance:
- HTML5
- CSS3 (including CSS Custom Properties)
- JavaScript (React 19)
- WAI-ARIA roles and attributes
- SVG for inline iconography
The Platform is designed to function with modern web browsers and assistive technologies including screen readers (NVDA, JAWS, VoiceOver), keyboard-only navigation, and high-contrast display modes.
4. Known Accessibility Limitations
We are aware of the following areas that do not yet fully meet WCAG 2.1 AA standards and are working to resolve them:
| Area | Issue | Status |
|---|---|---|
| Incident Simulator 3D Scene | The 3D WebGL viewport is not accessible to screen readers. A text-based alternative summary is provided for all visual states. | In progress |
| PDF Reports | Downloaded PDF reports are not fully tagged for screen reader navigation. We are working to add proper PDF/UA tagging. | Planned |
| Complex data visualisations | Some score charts and bar graphs do not yet have full ARIA-described text alternatives. | In progress |
| Mobile touch targets | Some interactive elements on small screen sizes may fall below the 44×44px minimum touch target recommendation. | In progress |
5. What We Have Done
- All form inputs have associated labels and descriptive placeholder text
- All interactive elements are reachable via keyboard navigation (Tab, Enter, Space, arrow keys)
- Focus indicators are visible on all interactive elements
- Colour is not used as the sole means of conveying information
- Text contrast ratios meet or exceed 4.5:1 for normal text and 3:1 for large text
- All images and icons have appropriate alternative text or are marked as decorative
- ARIA landmarks are used to define page regions (navigation, main, footer)
- Modals and dialogs trap focus and are dismissible via keyboard (Escape key)
- Page language is set in the HTML element
6. Feedback and Contact
We welcome your feedback on the accessibility of SafetyMeter. If you encounter barriers or have suggestions for improvement, please contact us:

8. Assessment Approach
Trusted Tech Africa assesses the accessibility of SafetyMeter through:
- Self-evaluation against WCAG 2.1 success criteria
- Manual keyboard and screen reader testing during development
- Automated accessibility linting in our development workflow
- User feedback from the community
We intend to commission a formal external accessibility audit in the next 12 months.
