engineering functional safety


In high-risk industries, safety isn't just a feature—it's the foundation. AAS Engineering is a specialized electrical controls engineering firm dedicated to Functional Safety. We provide the critical Front-End Engineering and Design (FEED) services that ensure your Safety Instrumented Systems (SIS) are designed, programmed, and commissioned to the highest standards, including IEC 61511 and IEC 61508. We bridge the gap between safety requirements and operational reality, delivering clarity and confidence for your most critical projects.

Is your safety out of complaince? we can help

  • Safety Instrumented Systems (SIS)

    Our certified TÜV functional safety engineers select and design systems that meet the target SIL/PL, ensuring hardware fault tolerance and architectural constraints are satisfied. We provide a rigorous, multi-stage V&V process. This includes verification during design and construction, culminating in a comprehensive final validation after commissioning. This step confirms the as-built system fulfills the original Safety Requirements Specification, delivering the documented proof of safety integrity required by standards like IEC 61511.

  • Hazard & Risk Assessment

    Our process starts with a HAZOP analysis, a collaborative and structured brainstorming session designed to uncover potential hazards and operational issues in your process. Once high-risk scenarios are pinpointed, we employ LOPA. This follow-on analysis acts as a scalpel, precisely evaluating the effectiveness of existing safeguards and quantifying the amount of risk reduction required from a Safety Instrumented Function (SIF). The output of LOPA is a clear, defensible SIL target, ensuring your safety investment is both adequate and cost-effective.

  • Controls Safety integration

    Bridge the gap between basic interlocks and a full Safety Instrumented System. Our Controls Safety Integration service provides machine safety solutions and functional safety for control systems by designing robust safety functions within your existing PLC or DCS. We implement safety automation including E-Stop circuits, light curtain integration, and process shutdowns following industry best practices. This approach delivers a cost-effective safety solution that enhances operational safety and protects your personnel and equipment.
