Functional safety ensures your equipment performs safely even when components fail. We conduct formal studies, perform SISTEMA calculations, and produce the documentation to prove it — to the standard required.
Functional safety actively prevents the failure of a system from causing harm to people and the environment. It achieves this through electrical, electronic, and programmable electronic technology — either maintaining a safe state or moving the system to one.
This is not a tick-box exercise. It is a structured engineering discipline that starts at concept and runs through to validation.
Define Safety Function Requirements — identify all safety-related functions and their required behaviour.
Determine Required Performance Level (PL) — risk assessment to establish the required PLr for each safety function.
Design and Technically Implement the Safety Functions — hardware, software, and architecture selection to meet PLr.
Determine and Quantitatively Evaluate the Achieved Performance Level — SISTEMA calculations and component data verification.
Verification — confirm the achieved PL meets or exceeds the required PL for each safety function.
Validation — test and confirm the complete safety system performs as designed under all relevant conditions.
SISTEMA v2.1+ for PL calculations. Allen-Bradley GuardLogix / Safety I/O. Safety PLCs and safety-rated field devices throughout.
Machine Safety — Safety-Related Parts of Control Systems. Primary standard for functional safety on machinery.
Instrument Society of America standards for instrumentation and automation in process industries.
AS/NZS standards applicable to the specific machinery type, industry sector, and installation environment.
Functional Safety of Electrical/Electronic/Programmable Electronic Safety-related Systems — reference for software and hardware requirements.
Functional safety is a legal and commercial requirement across Australian industry. Getting it right protects people, protects the business, and protects you.
