How to Conduct a Risk Assessment? A Step-by-Step Guide
Risk assessment means defining hazard sources, scoring each risk on a likelihood-severity matrix and building controls in a hierarchy. This guide walks through the method step by step, the equipment-risk link and how inspection data keeps the register alive.
Risk assessment is the systematic definition of hazard sources in the workplace; each risk is scored on a likelihood x severity matrix and controls are built in a hierarchy — elimination at source, engineering control, administrative measure, personal protective equipment. Law No. 6331 gives this duty to the employer; the aim is not producing a document but making the real field risk visible and manageable. On the engineering-control side, periodic inspection and test-analysis data form the spine of the table.
Step by Step Method
- 1. Hazard identification: equipment (crane, boiler, machine, installation), environment (chemical, noise, dust), organisation (shift, density) and behaviour sources; listed by walking the floor along the workflow.
- 2. Who is exposed: operator, maintenance, contractor, pedestrian groups; sensitive groups (new, untrained, disabled) marked separately.
- 3. Scoring: likelihood (rare-high) x severity (minor-fatal) matrix; acceptability class assigned.
- 4. Control hierarchy: engineering (guard, interlock, safety valve), administrative (procedure, permit, training), PPE; the top one is the permanent.
- 5. Monitoring-update: inspection results, measurements (earthing, tan delta, DGA, thermal), accident-near miss records and production-installation changes feed the table; revision time comes.
Tying Equipment Risk to Data
| Hazard source | Making it visible | Service link |
|---|---|---|
| Pressure vessel wall loss | UT thickness, DGA gas trend | pressure vessel control |
| Lifting member parting | Contact resistance, rope discard limit | Lifting machine control |
| Shock and arc | Insulation-earthing, thermal hotspot | Installation control |
| Rack collapse | Plumb-anchor, damage map | Rack static analysis |
Living Table, Falling Accidents
A risk assessment taken once and shelved is an outdated map after six months. The periodic inspection calendar matched to your equipment inventory, measurement trends and finding-closure minutes are the engineering input that keeps the table alive. Feed your machine-tool and door-rack findings into the matrix and let us build your site current map together.
