HRN (Hazard Rating Number) Calculator (Unbranded)

A semi-quantitative hazard rating tool that scores potential outcome, likelihood of occurrence, frequency of exposure, and number of persons at risk across a defined scale, multiplying the four factors to produce an HRN score between 0 and 2,400. The score places each hazard in a risk band from acceptable through to unacceptable, providing a structured, auditable basis for prioritising control measures.

Fully interactive and fillable online, complete in your browser, then download or print when ready.

Buy once, use forever. A one-off purchase gives you permanent access to use the tool as many times as you need, across as many incidents or assessments as required, no subscriptions, no usage limits, no hidden costs.

Includes a comprehensive written guidance document covering the HRN method, all scoring tables, risk band definitions, and guidance on when HRN is more appropriate than a standard risk matrix.
