New Task Ergonomic Screening

This screen belongs to change control, not to the assessment programme. Its misuse is chronological rather than categorical: the right form, filled in at the wrong point in the project, once the questions it asks have stopped being open.

Design-stage ergonomics is one of the few areas where the standards are more demanding than the regulations. Most regimes put a duty on designers and suppliers, and a duty on the employer to identify hazards before implementation, without prescribing a review; the standards describe the review itself.

The design-stage duty sits in different places in different regimes: on the designer and supplier in Australia, on the machinery manufacturer in the EU, on the employer's suitability judgement in Great Britain, and almost nowhere explicitly in the United States.

The form is short and every answer is a forecast. Four judgements decide whether the record changes the design or merely describes it.

Findings on this record are almost never about content. They are about dates, about middle answers, and about the distance between what the screen recommended and what was bought.

A dairy site installed a new case-packing cell on a filling line. The screening was raised properly, referenced the MOC, and was signed by ergonomics and engineering. It recorded lifting, repetitive work, moderate force demands and a chilled environment. Working height adjustable was answered Limited, because the infeed table was fixed at the conveyor deck level of 1,050 mm. Fits range of body sizes was answered Partly. No mock-up was planned. Every answer was accurate.

The screen was signed eleven days after the purchase order, because the ergonomist had been on leave through the design freeze and the project would not hold. Nine months in, three operators of around 1.6 m were reaching above shoulder height to place cases for four hours a shift. Two discomfort reports and a physiotherapy referral later, the fix was a platform at the infeed: a capital request, a hygiene review because it sat in a wash-down zone, and a shutdown window. Eleven months, and more than an adjustable table would have added to the order.

Nothing had been hidden. Limited and Partly were both true, and neither carried a consequence, because the form had no rule turning a non-Yes into a hold and no route by which a finding reached the purchase specification. The change afterwards was structural: the screening became a prerequisite for the requisition rather than for installation, and any answer below Yes now blocks sign-off until a design change or named acceptance is attached.

The form is one page. What fails is around it: the change that raised no screening, the recommendation that never reached the order, and the baseline assessment that was going to be booked once the project settled down.

KnowErgo

Holds the screening against the change and task registers, carries each recommendation into the design review, and blocks sign-off while a non-Yes answer sits without a change or an acceptance.

KnowSafe

Owns the management of change record, so a new or altered task raises the ergonomic screening as a prerequisite of approval rather than a document collected later.

KnowMaintain

Brings the maintenance and cleaning routines into the design questions, so strip-down, wash-down and fault-finding postures are examined by the people who will perform them.

Ella

Tracks screenings against project stage, flags any raised at or after procurement, and chases the baseline assessment date before the project closes and its budget disappears.

Management of change

The controlled process for reviewing and authorising planned changes to process, equipment, materials, layout or crewing before implementation, required by cl.8.1.3.

Prevention through design

Addressing occupational risk at the design and specification stage of equipment, processes and facilities, where elimination and engineering control are still cheap.

Anticipated demand

A predicted physical requirement of a task that does not yet exist, derived from design intent rather than measurement. Provisional, and always in need of a baseline check.

Anthropometry

Measurement of body dimensions across a population, used in design to set heights, reaches and clearances so small and large operators are both accommodated.

Reach envelope

The volume within which an operator can work without extending the shoulder or leaning from the trunk. Most often exceeded by a workstation that looked correct in plan view.

Mock-up

A full-scale rig of a proposed workstation, built cheaply and used by real operators before fabrication is released. The highest-yield ergonomic activity at design stage.

Machine-paced work

Work whose cycle rate is set by equipment rather than the operator, removing the micropauses recovery depends on and making rate a design decision, not a behavioural one.

Baseline assessment

The first full task assessment once the new task runs at rate, establishing the measured starting point against which any later redesign is compared.
