An original classification of technological safety systems is presented, for the purpose of assessing the actual or possible contribution of models of cognition to the design and operation of these systems. Systems are classified as passive or active; active as responsive or autonomous; autonomous as usual or unusual; unusual as dormant or latent; and latent as danger-centred or cognition-centred. For passive systems, cognitive models are of limited use. For responsive and usual systems relevant models are beyond reach. For dormant and danger-centred systems, models of cognitive capacity, load or control mode may be relevant. A good cognition-centred system would benefit from a contextual model that identifies the boundaries of what is usual or familiar. Such a model, and a related safety-system concept, SACHE, are outlined.
