FUNCTIONAL SAFETY

For the right safety level – anywhere!
Process and Machinery functional safety is one of Global Functional Safety’s (GFS’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 GFS’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).

Safety Lifecycle
Based on the Safety Lifecycle Model, GFS’s experts assist the customer through the different stages as defined in the standards. From the project’s conceptual phase to final commissioning and handover to operation & maintenance:

Define Risk (e.g. by use of HAZOP, What-if methods)
Determination of safety functions and required safety level (Performance Level PL / Safety Integrity Level SIL) Safety Requirements Specification
System Design
Validation and Verification of Design
Commissioning

In addition, GFS offers to assist with the preparation of the operating and maintenance procedures.

Functional Safety Management
One of the key points to obtain a safe design and operation is to implement Functional Safety Management. This methodology shall, among others, deal with general requirements, organizational requirements, implementing and monitoring of procedures as well as continuous risk evaluation and risk management.

Software solutions
GFS uses the leading software package to document the risk assessment, verification of the safety functions and component failure modes.

For correct documentation and reporting, we mainly use:
