Safety Instrumented System (SIS)

Industrial processes and plants increasingly experience concern about potential incidents that can affect people, assets and the environment in and outside the plant. A safety instrumented system (SIS) can dramatically reduce the risk of accidents in your plant. The ANSI/ISA 84 functional safety standards is widely used to implement safety instrumented systems and are 'good engineering practices in relation to Process Safety Management' (OSHA PSM 29 CFR Part 1910).

In the continuously evolving process industry, the need for expansion and upgrades of aging safety platforms and infrastructures is undeniable. Yokogawa understands your need to implement a safety system that is compliant with the new safety regulations, such as the ANSI/ISA 84 and NFPA standards.

Our expertise covers all major applications such as ESD (Emergency Shut Down), F&G or FGS (Fire and Gas Systems), BMS (Burner or Boiler Management Systems) as well as HIPPS or HIPS (High Integrity (Pipeline) Protection Systems).

Yokogawa has over 50 years of experience in the development and implementation of safety systems and is the world's most trusted automation solutions partner for efficient project execution and safety system solutions.
