End-to-end machine validation solutions
Most safety consultants only provide a theoretical advisory report, leaving you to guess whether the physical installation actually performs as intended under heavy industrial loads. This disjointed approach leaves your facility vulnerable to non-compliance, unsafe workarounds, and unmitigated risks.
MEX Engineering Group provides a complete, end-to-end machine validation solution. Maintaining strong machine-safety performance is more than meeting regulatory requirements; it requires physical, practical confirmation. By deploying stable, long-term experts who understand live production environments, we confirm that all installed safety measures effectively reduce identified risks to an acceptable level. From functional checks of interlocked guarding to reviewing the safety-related components of PLC control systems, we engineer strategic, long-term compliance that protects both your people and your production output.

Trusted by Australia’s Leading Manufacturers
MEX Engineering Group provides embedded site teams and engineering services to some of the country’s largest production facilities. We maintain critical infrastructure for industry leaders across FMCG, food and beverage, and high-speed packaging, including Tooheys, CHEP, Ullrich Aluminium, Goodman Fielder, and BlueScope Steel.
From Engineering Design to Boots-on-the-Ground Execution
We eliminate contractor inconsistency by managing the entire lifecycle of your plant’s compliance. Instead of handing a validation report over to a third-party contractor, we deploy our own in-house trained industrial electricians and mechanical fitters to execute any required upgrades.
Our process begins with isolating root causes and confirming the safety concept. We then execute precise, data-driven functional checks, ensuring that the engineering strategy is perfectly translated into a safe, high-performance reality on your factory floor. We secure your uptime by providing clear asset documentation, Performance Level validation, and ongoing fractional maintenance coverage.
Full-stack safety compliance and execution for industrial manufacturing
Our steel manufacturing client operates a heavy industrial environment where extreme structural loads and severe safety risks are a daily reality. MEX Engineering Group was engaged to execute a comprehensive slitting line safety upgrade and validation at their Chullora facility.
Our CMSE® – Certified Machinery Safety Expert began by performing a detailed machine safety assessment, followed by the design and construction of two new control panel consoles. Crucially, we didn’t just install the hardware; our in-house team programmed, commissioned, and comprehensively verified the new safety PLCs and HMIs. This full-stack execution and rigorous functional validation ensured our client achieved total regulatory compliance without enduring the delays and risks of managing multiple fragmented contractors.
Reliable machine validation framework
We follow a structured 6-step framework to embed our safety verification expertise inside your facility:
Safety design review
Evaluating the original safety concept and risk assessment to understand the required Performance Level (PLr) for the machinery.
Visual and structural inspection
Confirming that mechanical guarding and physical safety components are correctly positioned and securely installed.
Functional safety testing

Adapting to strict audit demands
Australian manufacturing facilities face increasing regulatory scrutiny and audit pressure from bodies like SafeWork. Relying on unverified safety systems or undocumented legacy machinery exposes your operations to severe compliance risks, imminent danger to employees, and revenue-draining shutdowns.
Confirming that your safety PLCs, presence detection, and interlocked guarding actually perform as intended is no longer optional. Comprehensive machine validation is required to protect your workforce, survive real audits, and safely transition to high-speed automation while preventing the massive cost of halted production.
