How is a risk matrix used in OEH practice?

• A. A grid that scores risk by likelihood and severity to prioritize controls and resources.
• B. A weather forecasting model.
• C. A budget allocation tool for marketing.
• D. A randomizing device for schedules.

Answer: (A)

In OEH practice, a risk matrix is a simple, visual way to rank hazards by how likely they are to occur and how severe the harm would be if it did. You set scales for likelihood (how often it could happen) and consequence (how bad the outcome could be), and then use a cross-tab to assign a risk level such as low, medium, or high. This single view helps you decide which controls to implement first and where to devote resources, because hazards with higher risk require more urgent or robust interventions. It also supports clear communication with stakeholders and keeps documentation consistent about why certain controls were chosen. For example, a hazard with both high likelihood and severe potential harm would land in a top-priority category, prompting strong preventive measures; a rare, minor issue might just be monitored. The matrix can be adapted to fit different settings with various scales and color codes. It’s not about weather prediction, marketing budgets, or schedule randomization—those tools serve different purposes, while the risk matrix specifically guides assessment and prioritization of occupational and environmental hazards.
