What this is
What is an ergonomic cost benefit record?
What is an ergonomic cost benefit record?
A business case that places the full cost of an intervention, capital, installation, training and running cost, against the cost it avoids: injuries, days lost, cover and overtime, and productivity or turnover effects. It exists because equipment is routinely refused when the cost is visible and the avoided cost is not.
Why does ergonomic equipment need a cost benefit case at all?
The cost of a fix is immediate and specific, while the cost of not fixing it, injuries, absence, turnover in a role only strong people can do, is diffuse and rarely attributed back to the task. Without this record, the comparison an approver needs is never put in front of them.
Who completes it?
Ergonomics prepares the case, finance validates the cost and avoided cost figures, and both sign it alongside a supervisor. It is a joint document, because a case that only ergonomics believes rarely survives approval.
Scope
When is an ergonomic cost benefit record required?
This record is the financial half of an intervention decision, and depends on assessment or redesign work that already identified the problem. Where the question is exposure, recovery or the redesign itself, a neighbouring template is the right instrument.
Use this template when
- An ergonomic equipment or intervention request is going into a capital approval process
- Injury, absence or turnover data exists for a task and needs setting against a proposed fix
- A task redesign case needs its financial justification recorded alongside the technical one
- A previously approved intervention is due for its post-install benefit review
- A rejected or deferred proposal is being reconsidered and needs the case updated
Do not use it for
- Cumulative Exposure Assessment, which measures total physical load across a shift; this record measures the cost of acting on that finding, not the exposure itself
- Work Rest Cycle Assessment, which judges whether recovery is adequate for the load, a technical question distinct from the case for changing it
- Task Redesign Record, which holds the redesign itself, what changed and the before-and-after scores; this record holds the money behind approving it
- Ergonomic Equipment Request, which is the operational request the equipment goes through once this case has justified it
- Any general capital expenditure case with no ergonomic basis, which belongs to the process that owns capital approval generally
Compliance mapping
Which ISO 45001 cl.9.1 requirements does this satisfy?
ISO 45001 cl.9.1 requires the organisation to monitor, measure, analyse and evaluate its OH&S performance, including control effectiveness, but does not prescribe a financial method. This record applies that requirement in the language an approval process actually uses.
| Clause | Requirement | Where it lands |
|---|---|---|
| ISO 45001 cl.9.1 | Monitoring, measurement and evaluation of OH&S performance, including whether controls are effective | Case |
| ISO 45001 cl.6.1.2.2 | Risk evaluation with defined methodology, used here to size the injury and absence cost an intervention addresses | Avoided cost |
| ISO 45001 cl.8.1.2 | Elimination and substitution ranked above administrative controls and PPE when an intervention is selected | Header |
| ISO 45001 cl.7.1 | Determination of the resources needed for the OH&S management system, reflected here as the full cost of the intervention | Cost |
| ISO 45001 cl.10.2 | Action following evaluation of a control's performance, including the decision to proceed, delay or decline | Case |
| ISO 45001 cl.10.3 | Continual improvement of the management system, of which a linked task redesign is one recorded instance | Related records |
What it does not cover
- Cumulative Exposure Assessment, which is the technical measure of shift-level physical load, and the input this record's avoided-cost side depends on, not something this record produces.
- Work Rest Cycle Assessment, which judges recovery adequacy directly, independent of any financial case.
- Task Redesign Record, which is the record of the redesign itself, what changed and its before-and-after scores, referenced here rather than duplicated.
- Ergonomic Equipment Request, which is the operational purchase or install request this case supports, not a replacement for it.
- A general capital appraisal, which covers non-ergonomic investment decisions and does not carry the injury, absence and productivity framing this record is built around.
Global
Ergonomic Cost Benefit Record requirements by country
No jurisdiction requires a cost benefit case by name. What differs is how directly cost may weigh against risk in the underlying legal test, which shapes how this record gets used to defend a decision.
Health and Safety at Work etc. Act 1974, reasonably practicable test
Requires risk to be reduced so far as reasonably practicable, weighing risk against the time, trouble and cost of controlling it.
Cost is legitimate in the UK test, but only prevails if grossly disproportionate to the risk; this record evidences the weighing was actually done, not a way to argue cost down the risk.
OSH Act General Duty Clause
No standard ties cost against risk explicitly; the duty is to address recognised hazards regardless of the cost of the fix.
A cost benefit case functions as an internal approval tool rather than compliance evidence; a documented cost case does not excuse leaving a hazard unaddressed.
ISO 45001 cl.9.1 and cl.7.1
Require monitoring and evaluation of control effectiveness and determination of the resources the management system needs.
Certification auditors expect an intervention's effectiveness, including its financial case, to have been evaluated rather than assumed at approval.
How to complete it
How to complete an ergonomic cost benefit record, step by step
The template calculates a payback period from whatever figures are entered. Whether those figures survive scrutiny is a matter the fields alone don't guarantee.
A payback period built on an optimistic productivity gain or understated running cost looks better on approval day and worse every day after. 'Assumptions Stated' and 'Conservative Assumptions Used' exist because the reviewer needs to see the reasoning, not just the result.
Cover and overtime cost, turnover attributable to the task, and a widened recruitment pool from removing a task only strong workers could do are real avoided costs that rarely get counted. A case limited to injury claims alone understates the actual benefit.
A record with no linked task, area or redesign record is hard to verify later, since nothing concrete exists for the post-install review to check the claim against. A Task Redesign ID gives the review something to measure.
Benefits Reviewed After Install is where the case earns credibility or spends it. A case approved and never revisited, however sound the original arithmetic, cannot demonstrate it was right, which is what makes the next proposal harder to approve.
What auditors find
Most common ergonomic cost benefit record findings
The case usually reads well at the point of approval. The findings concern what happens, or doesn't, afterward.
| Finding | Clause | What fixes it |
|---|---|---|
| Case approved on optimistic assumptions, with the benefit never checked after install. | ISO 45001 cl.9.1 | Schedule and complete the post-install review rather than leaving it at Scheduled or No. |
| Avoided cost limited to injury claim history, omitting cover, turnover and productivity effects. | ISO 45001 cl.6.1.2.2 | Complete the full avoided-cost set; the injury figure alone understates the case. |
| No task, area or redesign record linked to the business case. | ISO 45001 cl.10.3 | Require a Task Redesign ID or equivalent reference before the case reaches a decision. |
| Payback period stated without assumptions documented or marked conservative. | ISO 45001 cl.9.1 | Require Assumptions Stated and Conservative Assumptions Used answered before the case proceeds. |
| Capital cost captured, with installation, training or downtime cost omitted, understating total first-year cost. | ISO 45001 cl.7.1 | Complete every cost field before totalling; a partial figure produces an artificially short payback period. |
| Decision recorded without both ergonomics and finance sign-off. | ISO 45001 cl.10.2 | Require both signatures before a decision of Approved or Declined is treated as final. |
Case in point
Case in point: the case that was never checked
A packing line proposed a powered lift table to remove repeated bending from a task with a known injury history. The case put capital and installation cost against three years of injury claims, cover cost and a productivity gain marked significant, produced a payback period under a year, and was approved quickly on the strength of the number.
The lift table was installed, and nobody returned to check whether the productivity gain or injury reduction had actually happened, because the case had been approved and the file closed. Eighteen months later a second proposal, for a different task, was queried hard by finance specifically because the previous case's benefit had never been confirmed. The new case's technical merits were sound; the delay came entirely from the unverified promise of the last one. The fix was completing the review the first case had already committed to and never delivered.

From a document you fill in to a programme that runs itself
The case is a document, but the number inside it is a promise. What slips is the promise nobody goes back to check.
Holds the cost benefit record against the task or redesign record it supports, and flags a case with no benefit review logged after install.
Supplies the injury and absence history a case's avoided-cost figures are built from, grounding the estimate in the role's actual record.
Tracks the training cost and rollout an approved intervention depends on, so the total first-year cost reflects what has to happen.
Watches for cases with the benefit review left at Scheduled past its date, and raises it rather than letting the file close unverified.

Ergonomic Cost Benefit Record definitions and key terms
- Payback period
- The time for the avoided cost of an intervention to equal its total cost, used as the primary approval metric here.
- Avoided cost
- The injury, absence, cover, turnover and productivity cost an intervention prevents, set against its cost to justify the case.
- Conservative assumptions
- Estimates built to understate the benefit and overstate the cost, so the case that survives is the case likely to hold up in practice.
- Total first year cost
- Capital, installation, training and running cost combined for the first year, the figure the payback period is measured against.
- Reasonably practicable
- The UK legal test weighing risk against the time, trouble and cost of controlling it, where cost only prevails if grossly disproportionate to the risk.
FAQ
Frequently asked questions about ergonomic cost benefit record
Why does finance need to sign off an ergonomics record?+
Because the figures need to survive scrutiny beyond the function that proposed them. A case ergonomics alone believes is far more likely to be queried or rejected than one finance has already validated.
What counts as avoided cost, beyond injury claims?+
Days lost, cover and overtime cost, turnover attributable to the task, and productivity or quality gains all count, along with a widened recruitment pool where a task previously restricted who could be hired.
How conservative should the assumptions be?+
Conservative enough that the case stands up if the benefit comes in lower than hoped. An optimistic case that later underdelivers costs the programme more credibility than a smaller, reliable one ever would.
What happens if the case is declined or deferred?+
The record stays as evidence that the option was costed and considered, which matters if the same hazard is later challenged. A declined case with sound figures is not a wasted one.
Why review benefits after install at all, if the case was already approved?+
Because approval was based on an estimate. The review turns the estimate into evidence, and its absence is what makes the next proposal harder to get approved, regardless of how good it is.
Can this stand alone without a linked task redesign record?+
It can, but a case with nothing concrete attached is harder to verify at the post-install review. Linking a specific task, area or redesign record gives the review something to check the claim against.
