The design minimizes hazards and the adverse consequences of accidental or unintended actions.
Guidelines:
-Arrange elements to minimize hazards and errors: most used elements, most accessible; hazardous elements eliminated, isolated, or shielded.
-Provide warnings of hazards and errors.
-Provide fail safe features.
-Discourage unconscious action in tasks that require vigilance (Story et al., 1998, p.44).

Mayor’s Office (2001, p.23) suggests that ideal design should eliminate, isolate or shield design features that inherits hazardous or inconvenient properties. If the potential dangerous conditions are unavoidable, users should receive warnings when they approach the design feature; like providing "slippery slope" warnings.
