Читать книгу Risk Assessment - Marvin Rausand - Страница 57

Reason (1997) distinguishes between active failures and latent conditions. Active failures are events that trigger unwanted events. Examples of active failures are errors and violations by field operators, pilots, and control room operators.³ These are the people in the operation – what Reason calls the sharp end of the system. Latent conditions do not trigger an accident immediately, but they lie dormant in the system and may contribute to a future accident. Examples of latent conditions are poor design, maintenance failures, poor and impossible procedures, and so on. Latent conditions can increase the probability of active failures.

There are clear similarities in the way that Reason uses these terms and our way of using enabling events and conditions.
