Manual Picking Ergonomic Assessment

This assessment is one step in a larger programme, scored per pick face rather than per picker or per shift. Using it to cover the whole aisle, or a different task performed nearby, produces a record that does not map to a single golden-zone decision.

Manual handling in order picking is governed by general handling regulation and by ISO 11228's ergonomics standards, not by a picking-specific rule. What a regulator or auditor checks is whether the recommended mass, frequency and posture limits were actually applied to this pick face, and whether the avoid-assess-reduce hierarchy was followed rather than assumed.

The duty to control manual handling risk is close to universal. What differs is whether a specific hierarchy is written into law, and whether the standard behind the assessment is enforceable or advisory.

Most picking assessments are scored to the form and closed. What determines whether the record holds up is whether the golden zone was checked against how the zone is actually picked, and whether the highest control considered was recorded rather than assumed.

Manual picking assessments are unusual in that the golden-zone finding is almost always present in some form. What is missing is usually the follow-through: whether the finding changed the slotting, and whether the rate and recovery fields were read together.

A meat distribution site assessed its pick face for a fast-moving SKU family, found fast movers correctly placed in the golden zone, rated overall risk low, and moved on. Six months later the SKU was resized into two smaller case formats to meet a customer packaging spec, which doubled picks per hour at the same shelf. The assessment was not revisited because nothing about the zone had physically moved: same shelf, same aisle, same racking.

The corrective step was not a re-score of the same fields; it was recognising that picks-per-hour and recovery within the cycle are properties of the SKU's handling profile, not of the shelf location, and that a packaging change is exactly the kind of change that should trigger reassessment even when the physical layout is untouched.

The assessment is a score. What fails is the surrounding machinery: the reslotting that never happened, the aid that sat unused, and the zone that changed SKU without anyone re-running the form.

KnowErgo

Holds the manual picking assessment library against the pick-zone register, flags zones whose SKU or slotting has changed, and routes the reassessment to ergonomics.

Ella

Watches slotting changes, SKU resizing and discomfort reports for events that should trigger a re-score, rather than waiting for the periodic review.

KnowTrain

Connects a training-only control decision to the competency it produces, so a training entry on the form generates an actual requirement rather than a box ticked.

KnowSafe

Links the golden-zone finding to the Order Picking Risk Assessment and the Reversing and Manoeuvring Assessment covering the same aisle.

Golden zone

The vertical band, roughly knee to shoulder height, where lifting and reaching load the back and shoulders least; the reference band for slotting fast-moving stock.

Pick face

The section of racking or shelving a picker works from for a given SKU, the unit this assessment is scored per, not the whole aisle.

Recovery time

The pause between handling actions within a work cycle that allows the loaded tissue to recover before the next repetition.

Hierarchy of controls

The ranked sequence: elimination, substitution or redesign, mechanical aid, then administrative measures such as rotation or training, with training alone at the bottom.

Residual risk

The risk remaining once the proposed control, reslotting or a mechanical aid, is in place, the figure that determines whether the zone can run as designed.
