5x5 Risk Assessment Matrix Template
This structured 5x5 risk assessment matrix template enables you to systematically evaluate hazard probability and impact, calculate risk scores, and establish clear action priorities. Record key project details, select probability and severity ratings, determine your overall risk level, and define corrective measures. Conclude with a summary of recommendations for full traceability. Built for HSE teams and field operations, this template is fully adaptable to your organizational context and internal compliance standards.

How to Use This Checklist
- Open Risk Assessment and record the assessment date, the name of the person preparing it, the location, and the overview and instructions for the assessment.
- Describe the hazard or threat and record the assessment location or area so the hazard is tied to a specific part of the operation.
- Use the Risk Matrix – Probability Assessment section and the probability scale reference to choose the rating that best matches how often the hazard could occur, from Level 1 – Rare to Level 5 – Almost Certain.
- Use the Risk Matrix – Impact Assessment section and the impact scale reference to choose the rating that best matches the seriousness of the outcome, from Level 1 – Insignificant to Level 5 – Catastrophic.
- Use the Risk Matrix – Risk Level & Actions section to calculate the risk score by multiplying probability by impact, then record the risk level indicator and the risk priority category.
- Match the calculated score to the risk level: Low Risk (Score 1–4): Acceptable, Medium Risk (Score 5–9): Tolerable, High Risk (Score 10–15): Substantial, or Extreme Risk (Score 16–25): Intolerable.
- Record the recommended corrective and preventive actions for the hazard, then capture the signature and the finished time, along with the inspection real start and end dates, so the assessment is fully traceable.

What the 5x5 risk assessment matrix is for
A 5x5 risk assessment matrix gives you a consistent way to compare different hazards on the same terms. Instead of treating every issue as equally urgent, you rate how likely each hazard is to occur and how serious the outcome would be if it did. The matrix turns those two judgements into a single number, so you can sort hazards by priority and explain why one has been addressed before another. This template is built around that method. It takes you through hazard description and location, probability and impact rating, the calculated risk score, the risk level, the corrective and preventive actions, and a sign-off. It is designed for HSE teams and field operations and can be adapted to your organisation's context and internal compliance standards.
Why a structured risk assessment matters
Risk assessment is a legal duty in many workplaces, including duties owed under OSHA. The value of a structured matrix is not the score itself but the discipline of stopping to ask, for every hazard, how often it could happen and how bad it would be. That discipline surfaces hazards that might otherwise be accepted as normal, and it produces a record that shows the decision was deliberate. A consistent matrix also keeps assessments comparable across teams, sites, and dates. When everyone uses the same five probability levels and the same five impact levels, two assessments can be read side by side and the same score carries the same meaning. That is what makes the risk level a useful basis for deciding which actions to do first.
What a good risk assessment covers
A complete assessment starts with the basic context: the date it was conducted, who prepared it, and the location it applies to. The template captures these along with overview and instructions, so anyone reading the finished record understands what was assessed and on what basis. The core of the assessment is the hazard itself. Record the hazard or threat description and the assessment location or area. Being specific here matters: a hazard described as 'working at height' in a whole site is hard to act on, whereas the same risk tied to a particular task, area, or piece of equipment points directly at the control measure needed. The probability and impact scales are the two halves of the judgement. The template provides a scale reference for each, so you can rate the risk probability and then the risk impact using the same level definitions every time. A completed assessment also captures the calculated risk score, the risk level indicator, and the risk priority category, with the recommended corrective and preventive actions, the signature, the finished time, and the inspection start and end dates.
How to apply the probability scale
The probability scale asks how likely the hazard is to occur, given the controls that are already in place. The template sets out five levels for this judgement: - **Level 1 – Rare**: the event would only occur in exceptional circumstances. - **Level 2 – Unlikely**: the event could occur but is not expected. - **Level 3 – Possible**: the event might occur at some point. - **Level 4 – Likely**: the event will probably occur. - **Level 5 – Almost Certain**: the event is expected to occur. Use the probability scale reference in the template to keep the rating consistent, and rate the hazard as it actually stands, not as it would be if every control were perfectly followed.
How to apply the impact scale
The impact scale asks how serious the outcome would be if the hazard occurred. The template sets out five levels for this judgement: - **Level 1 – Insignificant**: little or no harm or disruption. - **Level 2 – Minor**: limited harm or disruption. - **Level 3 – Moderate**: a noticeable level of harm or disruption. - **Level 4 – Major**: serious harm or disruption. - **Level 5 – Catastrophic**: the most severe outcome. Use the impact scale reference in the template to keep the rating consistent. When you are unsure between two levels, the honest answer is often the higher one, because impact ratings are about the potential outcome, not the outcome you hope for.
Working out the risk score and priority
Once you have a probability rating and an impact rating, multiply them to get the calculated risk score. The template records both the calculation method and the result, so the arithmetic is visible rather than hidden behind a single figure. A score of 1 is the lowest possible outcome and 25 is the highest. The score then maps to a risk level indicator and a risk priority category: - **Low Risk (Score 1–4): Acceptable** - **Medium Risk (Score 5–9): Tolerable** - **High Risk (Score 10–15): Substantial** - **Extreme Risk (Score 16–25): Intolerable** Those four bands are the decision points. They tell you how much urgency the hazard carries and, in turn, how quickly the corrective and preventive actions need to be carried out.
Turning the score into action
The matrix is only useful if the score leads to something. For every hazard you assess, record the recommended corrective and preventive actions that will reduce either the probability or the impact — or both. Corrective actions deal with what has already been found; preventive actions reduce the chance of it arising again. Because the score is a product of the two ratings, it also shows you where to aim. Reducing the probability of a rare but catastrophic hazard, or reducing the impact of a frequent but minor one, both change the score in a way you can see and record. Re-score the hazard after the actions are in place to confirm the risk level has actually moved. The final fields — the signature, the finished time, and the inspection real start and end dates — close the record. They establish who completed the assessment and when, which is what makes the document traceable for internal compliance and review.
