UD Principle #5 - Tolerance for Error
Designs should provide interactions that minimize hazardous and unintended actions, warnings and fail-safe features. This also prevents the adverse consequences of accidents and errors. Universal Design aims to design for all users—as well as design in anticipation for different environments and users’ actions; this principle pushes you to think beyond the screen and how the system and user will interact with each other.

- Arrange elements so as to minimize hazards and errors: most used elements, most accessible, with hazardous elements eliminated, isolated, or shielded.
- Provide warnings about hazards and errors.
- Provide fail-safe features.
- Discourage unconscious action in tasks that require vigilance.
