HSE example risk assessments (qualitative hazard → control structure)
Canonical, citable source document for the IACE qualitative hazard→control pattern. The UK HSE risk-assessment template and worked examples give an openly-licensed, non-numeric model of how a hazard is paired with existing controls and further actions — used by IACE to validate that each identified hazard has at least one mapped control/measure.

Qualitative only: the HSE method is deliberately non-numeric — it does not
assign severity/probability scores or a risk matrix. It identifies hazards,
records existing controls, and plans further action. (Numeric severity×probability
comes from PRISM, see prism_risk_methodology.md.)
Assessment structure (7 fields)
The HSE blank template is a single table with seven columns:
| # | Column |
|---|---|
| 1 | What are the hazards? |
| 2 | Who might be harmed and how? |
| 3 | What are you already doing to control the risks? |
| 4 | What further action do you need to take to control the risks? |
| 5 | Who needs to carry out the action? |
| 6 | When is the action needed by? |
| 7 | Done (date completed) |
Method: walk the workplace, note hazards, talk to workers/safety reps, record who could be harmed, list existing controls, then decide what more is needed. HSE stresses the examples are illustrative — "do not just copy an example."
Named worked examples published: office-based business, local shop/newsagent, food preparation and service, motor vehicle repair shop, factory maintenance, warehouse.
Worked example — maintenance work in a factory (hazard → controls)
| Hazard | Existing controls / further action (summary) |
|---|---|
| Machinery / equipment | Guards and emergency-stop buttons fitted; add operator training on lockout/isolation procedures. |
| Slips, trips, falls | Housekeeping protocols in place; improve drainage and floor markings in work areas. |
| Chemical exposure | Safety data sheets held; upgrade ventilation, provide respiratory protection where needed. |
| Noise | Hearing protection supplied; assess noise levels, consider engineering controls at source. |
| Manual handling | Mechanical lifting aids available; refresh safe-lifting training. |
| Electrical | Maintenance staff qualified; set a formal inspection schedule and document lockout/tagout. |
Worked example — warehouse (hazard → controls)
| Hazard | Existing controls / further action (summary) |
|---|---|
| Manual handling | Proper lifting techniques, mechanical aids, ergonomics training, weight limits. |
| Storage & stacking | Appropriate racking, stable stacks, regular inspection, clear aisles / emergency routes. |
| Falls from height | Guardrails on elevated platforms, fall-protection equipment, working-at-height training. |
| Moving / powered equipment (FLTs) | Speed limits, segregated pedestrian zones, operator licensing, scheduled maintenance, visible warnings. |
| Slips, trips & falls | Floors clean/dry, walkways clear, lighting, suitable footwear, prompt spill clean-up. |
| Noise | Hearing protection where needed, noise barriers, equipment maintenance, sound-level monitoring. |
How these are used in IACE
- Hazard → control completeness check: the 7-field structure backs the IACE rule that every identified hazard must carry at least one existing control and, where residual risk remains, a further-action/measure entry.
- Control vocabulary: the worked-example hazard→control pairs seed IACE's library of typical machinery/warehouse measures (guarding, LOTO, segregation, manual-handling aids, PPE) for suggesting measures against a detected hazard.
- Qualitative complement: HSE supplies the narrative control side; PRISM supplies the numeric severity×probability side — IACE combines both.
