Ergonomic Risk Assessment

What an ergonomic risk assessment does

An ergonomic risk assessment systematically defines the factors in the work environment that increase load on the musculoskeletal system. The subject of the assessment is not the person’s health status, but the working conditions themselves: how long a position is held, how often a movement is repeated, how force-demanding tasks are done, and how far the work pattern allows for this loading.

This work is not a health screening and does not produce an individual diagnosis. Its output is a priority list that shows which working conditions the organisation needs to improve, and in which order. That way improvement decisions rest on observations made in the organisation’s own work environment, not on general assumptions.

The assessment does not replace the organisation’s occupational health and safety processes. Carrying out legal obligations is the responsibility of the organisation’s own occupational health and safety structure; the work here is a technical assessment that contributes to that process from a physiotherapy and ergonomics perspective.

Which loading themes are examined

The first theme is static loading: fixed postures held for a long time, unsupported arm and shoulder positions, the neck and trunk being held at the same angle continuously. This is the most common form of loading in desk work and usually continues unnoticed.

The second theme is repetitive movement. In tasks where the same movement is repeated intensively and at short intervals, the amplitude of the movement, its speed and the pauses between repetitions are assessed together. The third theme is demanding positions and reaching distances: layouts that require reaching, turning or leaning forward.

The fourth theme is the conditions created by the flow of work. Unbroken work blocks, task patterns that make it hard to change position, and teams in which a break habit has not settled prepare the ground for physical load to accumulate. That is why the risk assessment covers not only the physical setup but also work organisation.

These themes are not independent of each other. A mismatch that comes from screen height, when it combines with long unbroken work blocks, creates a different loading picture than it would on its own. That is why the assessment tries to define which conditions sit together in the same employee group, rather than scoring each theme separately.

Prioritising and reporting the risks

The risk themes that are defined are prioritised by looking together at how many employees they affect, how long they last, and how easily they can be improved under current conditions. Themes that can be reduced quickly by adjustment are grouped separately from themes that need a change in layout, equipment or work flow.

Findings are presented at department and task-type level inside the Corporate Ergonomics Assessment Report. The report explains, with its rationale, why a given condition has been defined as a risk theme; that way different units inside the organisation understand the same finding in the same way.

The report does not contain employees’ individual health information. Observations that belong to a person are shared only with that employee; the content presented to the organisation is made of grouped findings.

Repeating the assessment

The ergonomic risk picture is not fixed. Moving to a new office layout, team growth, a change in task content or an increase in the share of remote work can change the findings of the previous assessment. That is why the risk assessment is designed as a piece of work that is updated, not as a one-off document.

Reassessment is done comparatively with the previous findings: which themes have improved, which are being kept, which new conditions have appeared. This comparison lets the organisation follow its development on the ergonomics theme with its own data.

How the assessment is shared inside the organisation also affects the outcome. Sharing the findings in the same frame with human resources, the occupational health and safety unit and the relevant department managers prevents improvement decisions from being read differently in different units. That is why the report is written so that it keeps the technical detail while building a shared language inside the organisation.

An ergonomic risk assessment is more useful when it is designed as a piece of work that reviews conditions at regular intervals, rather than as a reaction to the organisation’s existing complaints. This approach lets improvement decisions be taken on a whole-organisation order of priority, not through individual requests.
