Noise Risk Assessment Example: A Worked Template for a UK Joinery Workshop
A fully worked noise risk assessment example for a small UK joinery workshop — noise sources, exposure estimates, action value comparison, controls, gaps, and action plan.
Covers UK employer duties only. Not legal advice.
Free noise risk assessment templates are easy to find. What is harder to find is a completed one — a filled-in example that shows what each section actually looks like when the boxes are not empty.
This worked example walks through a noise risk assessment for a small joinery workshop. Every section uses illustrative data so you can see the structure, level of detail, and reasoning that a practical assessment contains. Use it as a reference alongside your own assessment — not as a copy-paste substitute, because your workplace will have different noise sources, exposure patterns, and controls.
This is an illustrative example for a fictional workshop. It is not a template for direct use and is not a substitute for a competent assessment of your own workplace. For guidance on conducting the assessment itself, see How to Complete a Noise Risk Assessment.
The scenario
Business: A small joinery workshop in the West Midlands. 12 workers in five groups: 2 machine operators, 4 bench joiners, 3 assembly and finishing workers, 2 apprentices rotating across all areas, and 1 office-based administrator with occasional workshop access.
Operations: Cutting, planing, routing, sanding, and assembly of bespoke joinery products. Standard shift: 08:00–16:30 with a 30-minute break.
Why the assessment is needed: Multiple powered woodworking machines running throughout the day. The owner-manager cannot hold a normal conversation at 2 metres in the machine area — a rough indicator from HSE guidance that noise levels are likely at or above 85 dB(A).
Section 1: Noise source inventory
| Source | Location | Typical level | Operating pattern | Peak events |
|---|---|---|---|---|
| Circular saw (panel) | Machine shop, bay 1 | ~97 dB(A) | Intermittent, ~3 hours/day | Short bursts during crosscuts |
| Planer/thicknesser | Machine shop, bay 2 | ~93 dB(A) | Intermittent, ~4 hours/day | Feeding start/stop |
| Spindle moulder/router | Machine shop, bay 3 | ~96 dB(A) | Intermittent, ~2 hours/day | High-speed passes |
| Band saw | Machine shop, bay 4 | ~88 dB(A) | Intermittent, ~2 hours/day | None significant |
| Belt sander (bench) | Bench area | ~87 dB(A) | Intermittent, ~1.5 hours/day | None significant |
| Orbital sanders (hand) | Assembly area | ~83 dB(A) | Intermittent, ~3 hours/day | None significant |
| Dust extraction system | Ducted, central unit outside | ~82 dB(A) at duct openings | Continuous during production hours | None |
| Compressed air (blowgun) | Throughout workshop | ~90 dB(A) at 1m | Occasional, short bursts | Peak ~130 dB(C) during bursts |
Noise levels here are estimated from manufacturer declarations and HSE published benchmarks for woodworking equipment, not from a formal survey with calibrated instruments. A workplace with levels this close to and above the upper action values should consider a formal measurement survey for defensible evidence — see the discussion of when to use measurement vs estimation in UK Workplace Noise Exposure Limits.
Section 2: Worker exposure mapping
| Worker group | Noise sources | Estimated daily duration near source | Estimated LEP,d | Action value reached |
|---|---|---|---|---|
| Machine operators (2) | Circular saw, planer, router, band saw, dust extraction | ~7 hours in machine shop | ~93 dB(A) | Upper action values exceeded |
| Bench joiners (4) | Belt sander, dust extraction, background machine noise | ~6 hours in bench area, ~1.5 hours near machines | ~88 dB(A) | Upper action values exceeded |
| Assembly/finishing (3) | Orbital sanders, occasional machine use, dust extraction | ~3 hours near machines, ~4 hours in assembly area | ~84 dB(A) | Lower action values exceeded |
| Apprentices (2) | Rotate across all areas | Variable — worst case follows machine operators | ~90 dB(A) (worst case) | Upper action values exceeded |
| Administrator (1) | Office with door closed, occasional workshop visits | ~30 minutes/day in workshop | ~68 dB(A) | Below all action values |

Section 3: Comparison against action values
The Control of Noise at Work Regulations 2005 set three thresholds. For each worker group, the assessment records which threshold applies and what duties that triggers.
| Worker group | LEP,d estimate | Lower (80 dB(A)) | Upper (85 dB(A)) | Limit (87 dB(A) with protection) | Duties triggered |
|---|---|---|---|---|---|
| Machine operators | ~93 dB(A) | Exceeded | Exceeded | Check protection adequacy | Full duties: controls, mandatory HPE, zones, health surveillance, training |
| Bench joiners | ~88 dB(A) | Exceeded | Exceeded | Below with adequate HPE | Full duties as above |
| Assembly/finishing | ~84 dB(A) | Exceeded | Not exceeded | N/A | Assessment, HPE available on request, information and training |
| Apprentices | ~90 dB(A) worst case | Exceeded | Exceeded | Check protection adequacy | Full duties. Additional consideration: young workers may need extra monitoring |
| Administrator | ~68 dB(A) | Not exceeded | Not exceeded | N/A | No noise-specific duties |
For a detailed breakdown of what each threshold triggers, see UK Workplace Noise Exposure Limits.
Section 4: Existing controls
| Control type | What is in place | Notes |
|---|---|---|
| Engineering | Dust extraction ducted outside (reduces dust noise at source). Band saw blade guard acts as partial enclosure. | No other engineering controls for primary machine noise. Circular saw, planer, and router have no enclosures, barriers, or damping. |
| Administrative | Apprentices rotate weekly between areas. Break room is separated from workshop by fire door. | No formal time limits in the machine shop. No job rotation for machine operators. |
| Hearing protection | Disposable foam ear plugs available in a wall dispenser at the workshop entrance. | No record of who takes them or when. No fitting guidance. No information on the attenuation rating (SNR) of the plugs provided. |
| Signage | One "Ear Protection Must Be Worn" sign on the main workshop door. | No hearing protection zone boundaries marked. Sign is faded and partially obscured. |
| Training | Induction covers noise as part of general H&S. No dedicated noise awareness training. | No records of who received what training or when. |
| Health surveillance | None in place. | No baseline audiometry for any worker. No follow-up programme. |
Section 5: Gaps and action plan
| # | Gap identified | Action required | Who | By when | Status |
|---|---|---|---|---|---|
| 1 | No engineering noise controls on primary machines | Investigate enclosures or barriers for circular saw and router. Get quotes from two suppliers. Consult HSE guidance on noise controls. | Workshop manager | 8 weeks | Not started |
| 2 | Hearing protection is unsuitable — no SNR data, no fitting, no records | Source rated hearing protection (SNR ≥ 25 for machine shop). Implement issue log with name, date, product, and size. | H&S lead | 2 weeks | Not started |
| 3 | No hearing protection zones marked | Define zone boundaries (machine shop + bench area = above 85 dB(A)). Install compliant signage at all entry points. | H&S lead | 3 weeks | Not started |
| 4 | No health surveillance | Arrange baseline audiometry for all workers exposed at or above upper action values (machine operators, bench joiners, apprentices). Set up annual follow-up programme. | Owner-manager | 6 weeks | Not started |
| 5 | No dedicated noise training | Deliver noise awareness training covering: risks, hearing protection use, signs of hearing damage, right to health surveillance. Record attendance. | H&S lead | 4 weeks | Not started |
| 6 | No review schedule | Set 12-month review date. Define triggers for earlier review (new equipment, layout changes, health surveillance findings). | Owner-manager | 1 week | Not started |
| 7 | Assessment based on estimates, not measurements | Commission formal noise survey for machine shop and bench area to replace estimates with measured data. | Owner-manager | 12 weeks | Not started |
Section 6: Health surveillance requirements
| Worker group | Audiometry required? | Baseline test | Follow-up interval |
|---|---|---|---|
| Machine operators | Yes — upper action values exceeded | Within 6 weeks (action #4) | Annually for first 2 years, then as advised by OH provider |
| Bench joiners | Yes — upper action values exceeded | Within 6 weeks | As above |
| Apprentices | Yes — upper action values exceeded on machine days | Within 6 weeks | As above, with additional monitoring for young workers |
| Assembly/finishing | Not currently required — below upper action values | N/A | Reassess if exposure changes |
| Administrator | No | N/A | N/A |
Section 7: Review schedule and sign-off
- Assessment date: [date of assessment]
- Assessed by: [name, role, competence basis]
- Next scheduled review: 12 months from assessment date
- Early review triggers: New machinery, changes to workshop layout, changes to shift patterns, health surveillance results showing hearing deterioration, any worker complaint about noise
What this noise risk assessment example shows — and what to adapt
This worked example covers a specific scenario. Your assessment will differ in the details, but the structure applies to any workplace with regular noise exposure:
- Inventory every source — not just the obvious machines. Dust extraction, compressed air, and background noise all contribute.
- Map workers to sources and durations — the assessment is about people, not just equipment.
- Compare against all three thresholds — not just the upper values. Workers between 80 and 85 dB(A) still trigger duties.
- Record what you already have in place — this is the section most blank templates skip, and it is where most assessments are weakest.
- Write specific actions with owners and deadlines — "improve hearing protection" is not an action. "Source rated HPE with SNR ≥ 25, implement issue log, complete by [date]" is.
