Functional Safety

Safe Projects Start with Personnel

SIS SILverstone is a Keystone subsidiary who helps us provide clients with services regarding functional safety with associated design. Silverstone has functional safety engineering personnel that have supported our clients in their quest for compliance in the oil & gas, refining, chemical, mining, PHA/HAZOP facilitation, and other process and discrete manufacturing industries.

As regulations and technology continue to evolve and become increasingly complex, organizations expend considerable resources to ensure projects meet PSM standards (OSHA 1910.119) and functional safety RAGAGEP (Recognized and Generally Accepted Good Engineering Practices) (ISA 84/IEC 61511).
