Protecting people, assets and operations through engineered functional safety systems.
Enquire about safety systems
At FAIRFIELDS, safety is fundamental to how we design, integrate and support control systems.
We work with you to identify risk, define required performance levels and implement safety solutions that protect people, equipment and reputation.
From standalone machines to complex, multi-asset facilities, we develop safety systems that comply with recognised standards while remaining practical, maintainable and aligned with operational performance.
We believe safety should strengthen operations, not restrict them. Our approach begins with detailed risk assessment in line with EN ISO 12100, defining required safety functions before selecting the most appropriate architecture.
Our designs are built around internationally recognised functional safety standards including BS EN ISO 13849-1, IEC 62061 and IEC 61508. Whether the solution requires safety relays, configurable safety controllers or failsafe PLC systems, we integrate safety directly into the machine or process.
Our TÜV accredited engineers combine deep control system knowledge with practical site experience to deliver validated, documented and fully verified safety systems.
We support the full safety lifecycle, including:
• Risk assessment and hazard analysis
• SIL and Performance Level determination
• Safety concept development
• Hardware and software design
• SISTEMA calculations and verification
• Installation and validation testing
• Technical documentation and compliance support
The result is a safety system that reduces risk, supports productivity and stands up to regulatory scrutiny.
What our Safety Systems cover
We design and implement safety solutions across:
• Machine guarding and interlocking
• Emergency stop and safe isolation systems
• Immobilisation and safe access systems
• Safety PLC and distributed failsafe architectures
• Drive-integrated safety functions (STO, safe speed monitoring)
• Process and burner management safety systems
• High-integrity moving structures and infrastructure assets
• Safety-related instrumentation and sensor selection
• System upgrades to current legislation
• Obsolescence and migration of legacy safety systems
But what does it included?
Functional Safety
Our TÜV accredited engineers design systems in accordance with ISO 13849, IEC 62061 and IEC 61508, carrying out SIL and Performance Level assessments to define the correct level of risk reduction.
We develop documented safety cases, validate designs and provide full verification records to support compliance and audit requirements.
Safety PLC & Integrated Safety
Where flexibility and diagnostics are required, we implement failsafe PLC systems that combine standard control and safety functions within a structured architecture.
This approach reduces wiring complexity, improves fault diagnostics and supports future expansion while maintaining required integrity levels.
Machinery Compliance & UKCA Support
When machines are modified, integrated or upgraded, compliance responsibilities can change. We support clients with risk assessments, safeguarding design and documentation required to demonstrate conformity with the Supply of Machinery (Safety) Regulations.
Our team ensures safety performance aligns with operational requirements without unnecessary over-specification.
Drive-Integrated Safety
Modern drive systems offer integrated safety functions such as Safe Torque Off (STO), safe limited speed and safe brake control.
We design these functions into the overall safety architecture to reduce hardware complexity while maintaining required performance levels and safe access during maintenance or set-up.
Lifecycle Support & Validation
Safety does not end at commissioning. We provide validation testing, periodic inspection support, system audits and long-term service agreements to ensure your safety systems remain compliant and effective throughout their lifecycle.
