Is IEC 61508 Relevant To Me?

Generally, the significant hazards for equipment and any associated control system have to be identified by the specifier or developer via a hazard analysis. The analysis identifies whether functional safety is necessary to ensure adequate protection against each significant hazard. If so, then it has to be taken into account in an appropriate manner in the design. Functional safety is just one method of dealing with hazards, and other means for their elimination or reduction, such as inherent safety through design, are of primary importance.

IEC 61508 defines appropriate means for achieving functional safety in the systems it covers.

See the document Functional safety and IEC 61508 for further details.
