Safety Instrumented Systems (SIS)

The SIS is the instrumentation installed in a plant for the purpose of taking the process or specific piece of equipment in the process to a safe state. The SIS is designed to respond to upcoming plant emergency and generate the correct output before any hazardous event takes place.

The SIS requires planning and is designed to the particular characteristics of the plant. Once the SIS requirements are determined, the appropriate technology is chosen and the SIS in installed and tested for functionality and operability. Once the plant is operating the SIS must be maintained and checked at regular intervals.

This course has been designed to introduce participants to the design considerations and relevant information needed to properly select an SIS.  Participants will also be exposed to the process involve in choosing the technology that best fits to the plant as well as installation, testing and managing the SIS.

Day 1
Safety Instrumented Systems

    • Introductory
    • Design Considerations
    • Protection Layers
    • Safety Integrity Levels

On day 1, participants will learn about the fundamentals of the SIS. They will be exposed to the design considerations which involve life cycle and hazard and risk analysis. They will gain knowledge in determining the protection layers which give the overall protection available from operating the process to emergency response. The participants will be exposed to the process of determining the safety integrity level needed to meet the possible risks in operating the plant.


Day 2
Safety Instrumented System Technology

    • Choosing a Technology
    • SIS Evaluation
    • Hardware
    • Control & Safety Systems Integration

On day 2, participants will be exposed to the types of SIS that are available on the market as well as the elements used to evaluate “best fit” for the plant. The participants will learn about the initial evaluation to of the SIS once the technology has been selected. They will gain knowledge on the importance of selecting the proper hardware for the selected technology. The participants will learn about the precautions that must be considered in the integration of the control and safety systems.


Day 3
Safety Instrumented System Installation

    • Installing the SIS
    • Initial Testing
    • Functional Testing
    • SIS Checklist
    • Managing the SIS

On day 3, participants will be exposed to the requirements for installing the SIS. They will gain knowledge in the initial factory and site testing as well as functional testing once the SIS is installed. Once the SIS has been installed and tested the participants will learn what is involved in managing the SIS during normal operation.

This course is mainly targeted to instrumentation technicians working in the field as an introduction or refresher.

The course can be applicable to technicians working in other disciplines, equipment purchasers, procurement and storage personnel, job planners and immediate supervisors.
