Safety validation

According to lEC 61508 and lEC 61511 the safety validation should be performed in terms of the overall safety functions requirements and the overall safety integrity requirements, taking into account the safety requirements allocation for the E/E/PE safety-related system in designing. In particular PFDavg value has to be verified in the probabilistic modeling process for the architectures considered of the E/E/PE safety-related systems taking into accoimt the probabihstic interval criterion for selected SIL. [Pg.102]

In the example company that developed this lean design process, its use commences when an assumption is made that a project is of such magnitude that it will require following the steps outlined in its Request for Capital Expenditure Procedure. For purchases below the capital expenditure request level, the basics in the process are applied, but not as extensively. For example, if the machine shop supervisor submits a request to purchase a metal cutting saw, safety considerations would be established and they would have to be reviewed by environmental, health, and safety professionals as well as more than one level of management. Those safety requirements would be included in the purchase order. After receipt and installation of the equipment, a safety validation would be made. [Pg.259]
