Workstation ergonomics checklist: how to plan healthy and efficient workstations

On the shopfloor, millimeters and seconds determine safety, quality, and cycle stability. With an ergonomics checklist for the workstation, you assess grasping area, working height, postures, forces, and visibility systematically and make improvements quickly. This reduces strain, eliminates sources of error, and stabilizes cycle time without burdening the workflow with extra effort.

The guiding principle is clear: reduce strain, increase efficiency. To do this, you take the body dimensions of the entire workforce into account, typically from the 5th to the 95th percentile, plan reaches and working heights based on elbow height, and arrange parts by grasp frequency. The guide values in parentheses give you orientation. They belong in a pragmatic workstation analysis that stands up to the reality of assembly and production.

If you want to compare variants quickly and back up decisions as a team, Halocline supports you with VR. You build workstations with no training required and without CAD data, check grasping areas and heights with grasping area avatars for different body heights, measure distances, and spot problems in the workflow early.

Why is an ergonomics checklist important for safety, quality, and cycle time?

Ergonomics has a direct effect on process capability. Shorter grasping paths and neutral postures reduce mispicks and rework, and cycle time stays stable even at high frequency. If you minimize neck and back flexion as well as twisting, and the hands work at a suitable height, fewer compensating movements arise that cost time and endanger quality.

For reliable results, you plan for a range of people instead of an ideal type. Anthropometry ensures that short people don't have to overreach and tall people don't end up in awkward postures. In practice, this means setting working heights relative to elbow height, designing grasping areas based on real reaches, and placing heavy, frequently used parts close to the body.

Ergonomics is also a safety factor. Lower loads and lower grip or trigger forces reduce the risk of acute and cumulative injuries. At the same time, search times get shorter when displays are in the main field of view and material is ready in a logical order. The sum of these details results in robust ergonomic workstation design that proves itself in the cycle.

How do you put the checklist into practice?

Anthropometry

• Plan for the 5th to 95th percentile.
• Derive working heights from elbow height.
• For seated work, check knee clearance and legroom.
• Where people of different heights work at the same station, height-adjustable solutions have the advantage. They avoid stretching and bending and take the actual height at the workpiece into account.

Grasping area

• Frequently used parts in the primary area close to the body (about 25 to 45 cm), rarely used parts in the secondary area (up to around 60 to 70 cm).
• No grasping above shoulder height; provide heavy parts below shoulder height.
• Design two-handed work areas symmetrically so that both hands have equally long paths and holding and guiding stay cleanly separated.

Working height

• Precision work just above elbow height (about 0 to 5 cm above).
• Light assembly slightly below (about 5 to 10 cm below elbow height).
• Force-intensive tasks lower still (around 10 to 20 cm below elbow height).
• Always check the total height including attachments and workpiece so that the effective working level is right.

Sitting and standing

• When sitting, set the height so that the knees are at about 90 degrees and the feet rest flat.
• When standing, anti-fatigue mats and a footrest that makes it easier to shift weight provide relief.
• Being able to switch between sitting and standing reduces fatigue and stabilizes the cycle over the entire shift.

Postures and movements

• Neck flexion below 20 degrees where possible.
• Minimize back flexion and twisting by placing things close to the workpiece and using rotating fixtures.
• Keep wrists neutral and elbows as close to the body as possible.
• For repetitive tasks, micro-breaks of one to two minutes every 20 to 30 minutes help without disrupting the workflow.

Forces and loads

• Frequent lifting under 10 to 12 kg, infrequent lifting under 20 kg.
• Keep grip and trigger forces low (no more than 10 N, ideally under 5 N at high frequency).
• Pushing is preferable to carrying.
• Plan aids such as balancers, lift tables, or carts as a fixed part of the process, not as an exception.

Visibility and information

• The main field of view is tilted slightly downward (about 10 to 20 degrees), so no head rotation is needed.
• Place displays glare-free and easy to read, typically at a distance of 50 to 80 cm.
• Clear visuals shorten search time and reduce the risk of operating errors.

Tools and material supply

• One-handed tools as light as possible (under about 2.5 kg) or suspended from balancers.
• Handles suited to hand size and task, with low vibration and noise.
• Provide parts at a favorable height and in the right order.
• Cable and hose routing must not interfere with the grasping area or cause extra movements.

Environment

• Illuminance for assembly in the range of about 500 to 750 lx.
• Noise below 80 dB(A) where possible.
• Avoid drafts and provide non-slip standing surfaces.
• Clear, marked traffic routes secure material flow and prevent disruptions at the line.

Organization

• Fewer variants or clearly structured product families reduce complexity.
• Standardized workflows and job rotation distribute monotonous strain.
• Instructions make the intended posture and reach clear.
• Assess risks by frequency, strain, and duration, implement quick improvements first, and document before-and-after values for grasping path, working height, angles, and cycle time with clear responsibilities and deadlines.

How do you speed up ergonomic workstation analysis with Halocline in VR?

Halocline is the planning platform for production layouts and workstations. Here's how to proceed:

1. Build the workstation: in VR or on the desktop with library elements, from the table to racks and parts logistics. Sketch the material flow as it actually runs in the cycle. This quickly gives you a layout you can walk through right away.
2. Set body heights: Grasping area avatars show the optimal and maximum grasping area and the working planes for the gender and body height you set, calculated according to DIN 33402-2 and DIN EN ISO 14738. Set short and tall people, and the differences in reach and working height become visible without any real rebuilding.
3. Measure grasping areas and working heights: Use the measuring tool to check whether frequently used parts are in the primary grasping area (about 25 to 45 cm) and whether the effective working level suits the task. Document distances and heights as reference values.
4. Assess postures: Run through the workflow yourself in VR and record it. The ergonomics check rates the postures based on the key indicator method and marks problematic object movements in yellow or red. At these points, you move workpieces or displays until neutral postures result.
5. Check routes and workflows: The recording with realistic grasp sequences and intermediate storage shows routes and searching movements in the spaghetti diagram. This lets you correct the material layout and tool positions in a targeted way.
6. Compare variants: such as fixed versus height-adjustable, alternative rack layouts, or different tool holders. Create them as planning variants, record the workflow for each variant, and weigh the ergonomic effect and the impact on cycle time as a team.

During the team walkthrough, one person walks through the workstation in VR while assembly, industrial engineering, and occupational safety (HSE) follow along in spectator mode on screen. This creates acceptance and speed: decisions are made at the object, change rounds get shorter, and workstation analysis turns from a one-off project into a routine part of production planning.

Siemens in Karlsruhe shows how much time this saves: there, workstation design with Halocline became 4x faster.
