How to Use This Checklist

  • Start the session with the **Audit** section. Record the date the risk assessment is conducted, who prepared it, and the location it covers, so the completed matrix can be linked to a specific place and a specific assessor.
  • Open the **Risk Matrix: Probability** section and work through the probability scale one hazard at a time. Ask the people who actually do the job how often the hazard is likely to occur, and record your judgment against the scale rather than against a single memory of one incident.
  • Move to **Risk Matrix: Impact** and apply the impact scale to the same hazards. Make sure the impact column captures the scope of the worst realistic outcome, not the most common one. If you have more than one person contributing, keep the scale definitions visible and refer to them aloud so two people do not apply the same number to different severities.
  • In **Risk Matrix: Level of Risk**, read the probability and impact scores together to establish the risk level for each hazard. This is where the matrix does its work. Take the time to check that the two component scores still reflect your original judgments before you accept the combined level.
  • Close the assessment with the **signature** field and record the finish time, start date and end date. The sign-off is what tells the reader that a named person stands behind the scores and the reasoning.

Why a 5x5 matrix works

A 5x5 risk matrix scores each hazard on two dimensions (probability and impact) and combines them into a single level of risk. Probability answers the question "how likely is this to happen?" Impact answers the question "how bad would it be if it did?" A rating scale of five options in each dimension gives you twenty-five possible risk levels, which is fine-grained enough to separate a hazard that is unlikely but catastrophic from one that happens daily but causes minor harm. The two-dimensional approach forces a valuable discipline: you cannot score a hazard on how alarming it feels. You have to justify a probability and justify an impact, then show your work by combining them. That structure lets you prioritise across a long list of hazards in a way that a single severity rating cannot.

Assess both dimensions with equal care

The Audit section anchors the score to a time, place and person. A matrix produced without these details is difficult to use later because you cannot tell whether it still applies. The **Risk Matrix: Probability** section asks for the likelihood of the hazard occurring. The **Risk Matrix: Impact** section asks for the severity of the consequences if it does. Both dimensions need to be scored against their own definitions. A common mistake is to score every hazard as improbable if it has never happened, or as insignificant if the last occurrence caused no harm. Neither of those is the same as the true probability or impact of the hazard. > Apply the probability scale and the impact scale as independent judgments, then look at what the combination produces.

From scores to a level of risk

The **Risk Matrix: Level of Risk** section is where the two dimensions combine. A low probability with a high impact is not automatically a low risk, and a high probability with a low impact is not automatically acceptable; the combined level is what drives how quickly you act. Once the level of risk is set, you can rank hazards and allocate your attention where it is most needed. The matrix is a scoring tool, not the whole assessment. Your reasoning, the controls you already have, and the actions you intend to take all sit around the scores, not inside them.

Closing the assessment

Finish the assessment by recording the time and date the work was carried out and the period it covers. Then sign. A completed matrix with a named signature and a recorded date is a record that a competent person applied the scale at a known point in time. That record is what makes the assessment auditable, and it is what allows someone else to read the scores later and understand who agreed to them and when.

Frequently Asked Questions

The matrix itself does not define which hazards to look for, and you should not rely on it to tell you. Its purpose is to score hazards that you have already identified and described realistically. Use it after you have walked the work area, reviewed incidents and near misses, and spoken with the people doing the job.

A probability of 5 means the hazard is almost certain to occur, and an impact of 5 means the consequences would be severe. Multiplying them gives a risk level of 25, which falls at the top of the 5x5 scale. Treat a score like that as the trigger for immediate action, not as a label to record and move on from.

Not automatically. The matrix gives you the chance to compare risks against each other so you can prioritise, but acting on the result is a separate step. If your risk assessment is required by a regulation or a workplace procedure, the matrix output is the intermediate stage, and the actions you take and record are what discharge your obligation.

Start by making sure your probability and impact scales are defined in plain language that everyone applying them understands. The matrix gives consistent scores only when two people reading the same scale definitions reach the same number. Spend your effort there before you start scoring rows.
