Frequently asked questions
How is the risk level calculated?▼
The level is Probability × Severity (scale 1 to 5). The product from 1 to 25 defines the band: low, medium, high, or critical, shown on the matrix and table.
Is this for a formal risk assessment?▼
The tool helps organize your risk inventory and heat map for occupational safety programs. Formal assessment should be done by a qualified professional.
Is my data saved?▼
Yes. The inventory is saved automatically in your browser (localStorage) so you can continue later.
Can I export the matrix?▼
Yes. You can download PNG or PDF with the heat map, legend, and risk table, with no watermark.
