Quick answer
Examine the whole task: repetition, force, reach, posture, duration and work organisation. Reduce the risk through suitable task and equipment design, workload and recovery arrangements. Use an assessment tool suited to the activity and check improvements with the workers.
Why one posture instruction may miss the task risk
A packing job can combine repeated movement, force and awkward reach for a long period. HSE’s upper-limb guidance identifies these factors and the need to assess and control work-related risks.
Ask workers about difficulties and observe the real task, including busy periods. Do not assume a person’s discomfort identifies a diagnosis or proves that one factor is the sole cause.
Connect the risk factor to a design question
| Factor | Design question | Verification |
|---|---|---|
| Repetition | Can the movement or task sequence be reduced or changed? | Observe the complete cycle after the change. |
| Force | Can suitable tools or process changes reduce the effort? | Check use and any new safety hazard. |
| Reach and posture | Can the position of materials, equipment or work be improved? | Check the arrangement with different users. |
| Duration and recovery | Can the work pattern provide meaningful variation or suitable breaks? | Review actual work, including overtime. |
| Organisation | Are pace, resources and training suitable? | Ask workers whether the method is practical. |
Choose the assessment tool for the activity
HSE’s ART tool supports assessment of repetitive upper-limb tasks, including relevant production, packing and sorting work. It considers movement, force, posture and additional factors. Suitable learning is needed to use it reliably.
ART is not a DSE assessment. For screen work use the DSE workstation approach; use other appropriate methods for hazards outside a tool’s scope. A colour or score is a prompt for decisions, not proof that controls are complete.
Implement changes and check the whole effect
Work with employees to choose practicable controls. Changing reach or introducing a tool can affect other hazards, so assess the proposed change. Rotating people between tasks with essentially the same exposure may provide little useful variation.
Encourage early reporting of problems and obtain suitable occupational-health advice where needed. The guide concerns work design and assessment; it does not prescribe treatment or a universal stretching routine.
For relevant NI screen work, use HSENI’s DSE guidance, alongside the applicable NI framework for other tasks.
Example: redesign a repeated packing reach
A team repeatedly reaches across a bench to retrieve packaging. The supervisor observes the cycle with workers and reviews the location of materials, workspace and task pace.
The proposed layout is trialled safely and checked for both ergonomic improvement and new obstructions or equipment risks. Worker feedback and observation establish whether the change helps during normal output.
Common mistakes
- Giving posture advice while leaving an avoidable long reach.
- Using one assessment tool for unrelated hazards.
- Assuming job rotation always reduces exposure.
- Ignoring reported problems until absence occurs.
Next steps
Observe one repetitive task with its users and identify the combination of factors. Select suitable assessment support, implement a specific design improvement and verify it in normal work.
Check the scope and use of HSE’s ART tool — A task-appropriate assessment method and suitable competence are needed; ART does not cover every posture or DSE issue.
