A simple operator Idea has sparked a global safety innovation. It has been more than a decade in development, but Mass Products has been at the forefront of this real-world solution.
What began as a modest idea from a Gold Coast field operator in 2013 has grown into one of the water industry’s most influential safety innovations. The Safe Access Maintenance grate, widely known as SAM, wasn’t created in a boardroom. It was born in the field, by operators frustrated with unsafe, outdated requirements for working around manholes and confined spaces.
Mass The Safe Access People, the small Gold Coast company behind SAM, have taken on the role of continuous innovator improving, testing, and evolving operator-led ideas into a world-ready engineered solution. SAM’s development reflects a rare commitment to frontline reality rather than administrative theory.
2013: The first prototype
SAM’s origin began when a City of Gold Coast operator approached Mass, seeking a circular grate to fit over common manholes. Operators accessed multiple assets per day, but harness systems were impractical, slow, or impossible to tie off safely. They needed a simple, lightweight engineered barrier to prevent falls while allowing work to continue safely. That request sparked a decade-long evolution.
2014: Collaboration unlocks new capabilities
The City of Gold Coast initiated a formal collaboration with Mass to refine the grate. The next major advancement was adding a slot, allowing the grate to protect workers above while preventing tools, debris, and objects from falling on personnel below. Workplace Health and Safety officers soon confirmed that once the grate was installed, a full confined-space setup was no longer required. This eliminated the need for harness systems, a three-person crew, and about $500 worth of equipment per job. Operator risk decreased, and productivity improved.
2015: The half-door design
Operator feedback led to the addition of a half-opening door in the grate. This feature allowed tools, CCTV equipment, and drain-cleaning gear to pass through the grate without removing it—transforming how maintenance activities were conducted.
2016: Sydney Water drives the next evolution
Sydney Water took the innovation to the next level—literally bringing every type of manhole cover and frame they worked with daily to Mass’s facility for a week-long, hands-on prototyping sprint. It was an intense collaboration that pushed the design further than ever before.
Key upgrades included:
- A nylon roller to protect sensitive CCTV cables and hoses
- Compatibility with multiple manhole sizes, including the notoriously tricky triangular frames
- A sacrificial pinch-weld strip to safeguard high-value equipment during use
The result? A universal, field-tested design that didn’t just impress—it became mandatory across Sydney Water’s entire network, with over 250 units deployed. This partnership didn’t just improve safety gear—it redefined what utility-led innovation can achieve.
2017: A compact foldable version
Fleet managers requested a SAM version that fit smaller modern vehicles. Mass responded by developing a fold-in-half grate offering the same protection with greater portability.
2018–2019: SAM goes international
SAM made its international debut at two of the world’s biggest water industry events—IFAT in Germany and WEFTEC in New Orleans—where it quickly turned heads and sparked global interest. Riding the wave of enthusiasm, Mass teamed up with U.S.-based Halliday Products to tailor a version specifically for American utilities. By 2019, SAM had officially entered production in the United States, marking a major milestone in its global journey.
2021: Solving high-pressure jetting risk
When Veolia Brisbane approached Mass with a tough challenge—could SAM withstand the intense forces of high-pressure jetting?—it pushed the team into new territory. While the existing grate was more than capable for low-pressure plumbing, high-pressure systems came with strict Australian safety regulations, requiring full water containment and anti-withdrawal compliance. Rising to the occasion, Mass launched into extensive R&D and real-world testing. The result? A world-first engineered safety solution that met every requirement—tackling one of the most hazardous routine maintenance tasks in the water industry head-on.
2022: Recognition and further innovation
This high-pressure SAM version was nominated as a finalist at the Australian Water Association Safety & Innovation Awards. Though it did not win, Mass’s joint venture product “Lock It Out,” developed with Logan Water and Downer, won the award. This device introduced a new method to safely isolate sections of the water network.
2023 and Beyond: Standardisation and sustainability
The next chapter is all about global standardisation and advancing a lightweight, recycled-plastic version of SAM, tailored specifically for CCTV inspection work. But most importantly, future innovations will continue to be shaped by the same driving force that started it all—feedback and insight from the operators out in the field.
SAM: Where real-world safety meets real-world work
SAM has done more than improve safety—it’s transformed how safety is understood and applied in the field.
Across Australia, many operators still face risky conditions: tying off to objects never meant for fall restraint, working beside open manholes, and relying on layers of paperwork instead of practical safeguards. There’s often a gap between what safety policies say should happen and what actually does happen on the ground.
SAM bridges that gap. It replaces ropes, exclusion zones, and harnesses—which are often difficult, impractical, or even non-compliant—with a simple, engineered barrier that meets safety legislation while fitting seamlessly into everyday operations.
SAM isn’t about theoretical safety. It’s about real-world safety—a physical solution that replaces administrative controls with something tangible, effective, and easy to use.
For the first time, operators can maintain critical underground infrastructure with gear that’s built by operators, for operators—keeping crews safe, efficient, and confident on every job, every day.
