Functional Safety is one of DotBlue’s key performance areas, and we support our customers with all kinds of Functional Safety aspects ranging from management systems to procedures for equipment selection. It is our intention to make your working place safer.

Experts in IEC standards
The basis for DotBlue’s work with Functional Safety are the standards IEC 61508, IEC 61511, IEC 62061 and ISO 13849. These standards are the key elements for safety design and are applicable to all kinds of industry. They also define the framework conditions for design, engineering, commissioning, operation & maintenance including change of Safety Instrumented Systems (SIS).
