Engineering Utility design

Designing ergonomic utilities

Author: Steve Bonte – Senior Project Engineer

In industrial environments, the focus is often on performance: flow rates, pressures, temperatures, and availability. Rightly so. But one crucial factor is too often underestimated: the people who work with these installations.

Ergonomic utilities design, starting from the perspective of the technician and operator, is not a nice-to-have. It is essential for reducing work-related stress, preventing errors, and carrying out maintenance more quickly and more safely.

Smart layout: from technical logic to operational overview

A well-thought-out layout of utility rooms and installations ensures that technology and use reinforce each other. It’s not just about where something “fits”, but about where it is logical and safe to use. Concretely, this means:

Safe and unobstructed walkways
Clearly defined paths, sufficient free space around components, and no crossings with hot, moving, or pressurised parts. Fewer obstacles means a lower risk of incidents.
Functional zones
Separation between operating zones, maintenance zones, and emergency facilities. This way, every user intuitively knows where to go for which task.
Clear panels and instrumentation
Logically grouped gauges, displays, and control panels, placed at ergonomic viewing and reaching height. Deviations and alarm situations are recognised more quickly, with less chance of interpretation errors.

A good layout not only reduces risk, but also shortens intervention times for inspection, maintenance, and malfunctions.

Why the human factor matters

Utilities are still too often designed from a purely technical perspective. The user only comes into the picture during commissioning, or worse, when the first problems arise.

This leads to increased work-related stress, a higher chance of errors due to poor accessibility, and longer downtimes with higher maintenance costs as a result.

In practice, we see the same pattern recurring: when components are not set up ergonomically, motivation to consistently follow up on installations also declines. If technicians have to scramble between cable trays, squeeze through narrow passages, or face a real risk of burns because insulation in “less visible” areas has been done inadequately, preventive maintenance drops into the background. Action is only taken once something fails.

What seemed like a design choice thus becomes a structural operational problem.

By integrating human-centered design right from the design phase, you create installations that support people instead of working against them. This delivers measurable gains in safety, efficiency, and maintenance culture.

Ergonomics affects not only how safely someone works, but also how consistently an installation is managed.

“Utilities often work behind the scenes, but for us they are crucial: designed to be safe, reliable, and easy to maintain.”

User-friendly systems: designed for maintenance

Ergonomics does not stop at the production area. The utilities themselves must also be designed with maintenance and operation in mind. Key points of attention:

Accessible valves, filters, and drain points
(ISO 6385, EN 614)
- No maintenance at knee height behind pipework.
- No tasks above shoulder height without aids.
Unambiguous and consistent operation
(EN 60204-1, ISO 12100)
- Clear tagging and colour coding.
- Uniform operating philosophy.
Practical ergonomic provisions
(EN 14122, EN 12464)
- Correctly installed platforms and stairs
- Sufficient lighting.

Ergonomics underpinned by standards

Standards only have value when they lead to better decisions on the shop floor. Ergonomic guidelines therefore translate directly into concrete design choices for utilities.

According to ISO 6385 and EN 614-1, valves are placed within the ergonomic reach zone, typically between 700 and 1,600 millimetres above floor level. Filters and drain points are installed at a height that allows maintenance to be carried out while standing upright. Pressure gauges, flow meters, and displays are positioned within the natural field of view so that process values can be read at a glance. By grouping critical parameters per utility, diagnosis in the event of deviations becomes faster and more targeted.

EN 60204-1 and ISO 12100 emphasise the importance of consistent and unambiguous operation. Switches, emergency stops, and local controls are labelled uniformly and applied according to a fixed logic across different utilities. This reduces the risk of operating errors, especially during interventions under time pressure.

The layout of the room itself is also decisive. Free space around pumps, skid frames, and electrical cabinets is determined on the basis of maintenance needs, not only installation requirements. According to ISO 14122-2, walkways must be at least 800 mm wide; for low-frequency interventions (less than two hours per day) this can be reduced to 600 mm. By clearly separating walkways and work zones and avoiding crossings with hot pipes or moving parts, the risk of incidents during both normal operation and maintenance is reduced. Proper lighting, in terms of both light level and positioning, is essential to ensure safe working (ISO 12464).

What SPARQ does

At SPARQ, we design utilities not only according to standards and specifications, but also in line with real-world working conditions. We combine technical expertise with operational insight and treat ergonomics as a fully-fledged design parameter.

No passing problems down the line. No compromises on safety. Simply: solutions that work.

Conclusion

Utility rooms are the beating heart of an installation. Yet they are still too often designed without sufficient attention to the human factor. Smart layouts, clearly arranged panels, safe walking routes and easily accessible components make a measurable difference.

Ergonomics is not a luxury. It is an investment in safety, efficiency and reliability.
