Safety & Environmental Risk Matrix

Find out what your biggest risk is before it finds you.

Order & safety

What it is and when to use it

Without a structured review, an owner usually finds out what their worst operational risk is after it already happened — an injury, a fine, a spill, a shutdown. This matrix walks every task or area, scores likelihood and severity, and points a limited safety budget at the two or three risks that actually matter.

Worked example

Risk matrix worksheet filled in with a worked example. Conclusion: Chemical storage scores 20 (4×5) — the highest risk in the shop, with no engineering control yet. Sections: 5×5 matrix · where each risk falls, Risk register, Hierarchy of controls, Result and action.
A chemical storage 4×5 high · B handling 3×3 moderate · C panel 2×2 low after LOTO

What goes on the sheet

  1. Task/area/process evaluated
  2. Hazard identified, by category: mechanical, chemical/environmental, ergonomic, electrical, fire
  3. Who or what is exposed: operator, community, environment, equipment
  4. Existing controls, and likelihood / severity scored 1-5 each (severity includes environmental impact, from contained on-site spill to reportable release)
  5. Risk score (likelihood × severity) and color-coded risk level (low/medium/high/critical)
  6. Recommended additional controls, following the hierarchy: eliminate, substitute, engineering control, administrative control, PPE
  7. Owner, target date, residual risk after controls

In a business like yours

  • Pool service company: chemicals, ladders and driving scored side by side, so the top risk gets fixed first.
  • Restaurant kitchen: hot oil, knives and wet floors ranked by likelihood and severity.
  • Small shop floor: which machines need a guard or a lockout before the next hire starts.
